A stroke occurs when blood flow to a part of the brain is disrupted, either by a blockage (ischemic stroke) or bleeding (hemorrhagic stroke). This deprives brain cells of oxygen and nutrients, causing them to die. As a result, the functions controlled by that part of the brain are affected, such as movement, speech, and cognition. The symptoms of a stroke can vary depending on the area of the brain affected but may include weakness or numbness on one side of the body, difficulty speaking, vision problems, and loss of balance or coordination.
Atopic dermatitis, also known as atopic eczema, is a condition that causes the skin to become dry, itchy, and inflamed. Atopic dermatitis is the most common chronic inflammatory skin disease. It usually begins in infancy or childhood but can develop at any age. [1]
There are many different types of atopic dermatitis. The most common ones are:
This is the most common form, often starting in childhood. It causes dry, itchy, and inflamed skin, usually on the face, elbows, and knees. [2]
This occurs when your skin reacts to allergens or irritants like soaps, fragrances, or metals. It causes redness, itching, and sometimes blisters. [3]
This type affects oily areas like the scalp, face, and chest, causing redness, scaling, and dandruff-like flakes. It is linked to yeast overgrowth and genetics. [4]
This type appears as round, coin-shaped patches of irritated skin, often after skin injuries like cuts or insect bites. It is more common in adults. [5]
Atopic dermatitis happens due to a mix of genetics, immune system issues, and environmental factors.
If your family has a history of eczema, asthma, or allergies, you will likely develop atopic dermatitis. If one parent has atopic dermatitis, your risk of developing it is 50%, increasing to 80% if both parents are affected. Similarly, a gene mutation can compromise your skin barrier, leading to dryness and increased sensitivity to irritation. [6]
Your immune system may overreact to harmless substances, leading to inflammation, redness, and itching. [7]
A weak skin barrier allows moisture to escape and irritants, allergens, and bacteria to enter, making your skin dry and easily inflamed. [6]
Pollen, dust mites, pet dander, soaps, and fragrances can trigger flare-ups by irritating your skin. [8]
Cold, dry air can worsen eczema by drying out your skin, while hot weather and sweating can cause itching and irritation. [6]
Emotional stress can trigger or worsen eczema by increasing inflammation in your body. [9]
People with atopic dermatitis may report periods with less marked symptoms followed by periods when symptoms are more severe, known as flare-ups. There may be various triggers that may lead to such flare-ups, such as strong soaps, detergents, skin care products, perfumes, makeup products, fabrics like wool or linen, pollen, mold, dust mites, animal dander, tobacco smoke, stress, anger, anxiety, low humidity, dry skin, sweating, or skin infections. [10]
The most common symptom of atopic dermatitis is itching. Other common symptoms include:
Atopic dermatitis usually starts with dry, itchy skin that becomes inflamed due to repeated scratching. In the early stages, the skin appears red and irritated and may have small bumps that ooze fluid. As the condition progresses, persistent scratching and rubbing cause the skin to thicken and become rough, a process called lichenification. This thickened skin develops deep lines, a leathery texture, and darker or lighter patches than the surrounding skin. Lichenified lesions are more resistant to treatment and can cause chronic itching and discomfort, often worsening in flare-ups. [11]
Examination of the lesion is the initial and the most important way to diagnose the conditions. You might need repeated examinations by your doctor to recognize the type of atopic dermatitis. Other tests that might be helpful to diagnose eczema are:
A dermoscopy is a tool your doctor may use to examine your skin closely. This handheld device magnifies the skin’s surface and helps the doctor identify patterns and small details that may not be visible to the naked eye. Dermoscopy can help distinguish atopic dermatitis from other skin conditions, ensuring an accurate diagnosis. [12]
Since atopic dermatitis can be triggered by allergens, your doctor might suggest allergy testing. Skin prick tests or blood tests can help identify environmental or food-related triggers that might worsen your symptoms, like pollen, dust, or certain foods. These tests can assist in managing flare-ups by avoiding triggers. [13]
Patch testing is a special allergy test that may be done if your doctor suspects that a contact allergen could trigger your symptoms. This test involves applying small amounts of different substances to your skin to see if any cause irritation or allergic reactions. It helps identify potential triggers that might be worsening your eczema. [14]
In some rare cases, a skin biopsy may be performed when the diagnosis is unclear. A small skin sample is removed and examined under a microscope to rule out other skin diseases with similar symptoms, such as psoriasis or contact dermatitis. [15]
Various treatment options are available, and the choice is made based on the type, stage, and severity of the condition.
One of the most important aspects of treating atopic dermatitis is regularly using moisturizers. These help lock moisture into your skin, which is key because dry skin can trigger or worsen flare-ups. Moisturizers come in different forms, such as creams, ointments, or lotions. Ointments are thicker and work better for severe dryness, while creams are lighter and can be used more frequently. It’s best to apply moisturizers right after bathing when your skin is still damp, as this helps to trap moisture in. Emollient-rich moisturizers can help create a protective barrier that reduces water loss and soothes irritated skin. [16]
Topical corticosteroids are often prescribed to reduce inflammation and itchiness. These medications are available in different strengths, from mild to potent, depending on the severity of the condition. You have to use them sparingly and only during flare-ups to avoid side effects like skin thinning. A milder steroid may be preferred for sensitive areas, like the face or groin. [17]
If your condition is severe or you need to use steroids for a very long period, topical calcineurin inhibitors, such as tacrolimus or pimecrolimus, can be your alternative. These medications help to control inflammation by inhibiting the immune system’s inflammatory response without the risks associated with steroids. They’re typically used in sensitive areas like the face or eyelids. [17]
For more severe cases of atopic dermatitis, doctors might prescribe oral medications, such as oral corticosteroids or immunosuppressive drugs like cyclosporine. These suppress the immune system’s overactive response and reduce inflammation. Systemic medications, however, are typically used as a last resort due to potential side effects. [18]
Since it is one of the most common symptoms of auto dermatitis, antihistamines are often recommended. They work by blocking histamine, a substance released by your immune system during an allergic reaction, which can cause itching. These can be helpful, especially at night, as they may also have a sedative effect to help with sleep when itching is severe. [17]
Phototherapy (or light therapy) involves exposing the skin to controlled amounts of ultraviolet (UV) light under medical supervision. This treatment can help reduce inflammation and improve symptoms, particularly in severe cases of atopic dermatitis that don’t respond to topical treatments. It’s commonly used in cases where the condition is widespread and persistent. [18]
Antibiotics are not needed for dermatitis, but with the cracks in the skin because of atopic dermatitis, there is a very high chance of infection. Atopic dermatitis is commonly associated with infections caused by Staphylococcus aureus. Managing these infections can help prevent the condition from worsening. [19]
Making lifestyle adjustments is crucial in managing atopic dermatitis. This includes avoiding known triggers like harsh soaps, certain fabrics (such as wool), and hot water. Using gentle, fragrance-free skin care products and wearing soft, breathable clothes can also help minimize irritation. Additionally, managing stress through relaxation techniques like meditation or yoga can prevent flare-ups since stress is a known trigger. [20]
People with atopic dermatitis may be more likely to develop other health conditions.
Duchenne muscular dystrophy (DMD) is a genetic disorder marked by progressive muscle degeneration and weakness. It can be inherited, meaning it gets transferred from parents to the child, and is known to be one of the most severe forms of inherited muscular dystrophy. [1] It affects approximately 1 in 3500 male births worldwide. [2]
DMD is an X-linked recessive disorder caused by alteration in the dystrophin gene, which encodes the protein dystrophin. [3] The gene makes a protein called dystrophin, important for keeping muscle cells strong. [4] The mutation of this gene leads to various muscle disorders, and DMD is one of the most common pathologies. [5] Without dystrophin protein, muscles become more easily damaged, leading to weakness and wasting. Over time, muscle tissue is replaced by fat and scar tissue. [6]
The first signs and symptoms of DMD may appear as early as 4 months; most signs develop around 2 to 3 years. [7]
In the case of DMD, muscle weakness selectively affects the limb muscles closer to the trunk. This is known as proximal muscle weakness. [8] The muscles of the hip, pelvic areas, and thighs are affected first, followed by the involvement of the shoulder muscles. Children often exhibit difficulty with activities such as running, jumping, and climbing stairs. [9, 10]
DMD often involves the proximal muscles, resulting in difficulty standing up due to weakness in the hip and thigh muscles. They use their hands to “walk” up their body to compensate. They push off from the floor to their knees and then use their hands to push themselves upright. [11]
In most patients, the calves appear enlarged. This is due to pseudohypertrophy, which replaces muscular tissue with fat and connective tissue. Hypertrophy of the tongue and muscles of the forearm can also be seen, although it is less common. [12]
Children suffering from DMD have delayed milestones such as sitting, standing, and walking. For instance, a delay in the age of first independent walking is common in DMD. [13]
Cognitive delays and intellectual impairment are seen in most people with DMD. Children with DMD experience delays in speaking and other cognitive functions. [14]
DMD can present with low bone mineral density and a higher risk of bone fractures. Moreover, corticosteroid therapy, an authorized DMD treatment, may have a variety of consequences on the health of the bones in DMD patients. [15]
Features of cardiomyopathy usually develop in the early teens. Dilated cardiomyopathy may present with different symptoms, such as persistent tachycardia, signs of heart failure, and arrhythmia. [16]
The diagnosis of DMD usually begins with your doctor noticing signs like muscle weakness or delayed milestones, such as trouble walking or climbing stairs. If your doctor suspects DMD, they may start by asking about your family history since this condition is often inherited. They might also perform a physical exam to check for specific signs, like calf muscles that look large but feel weak.
Your doctor may recommend a blood test to measure your creatine kinase (CK) levels to confirm the diagnosis. CK is a protein that leaks into your bloodstream when muscles are damaged, and high levels can be an early clue for DMD. Serum CK is elevated even before the development of clinical features. Levels of serum CK peak by the age of two and are often 10 to 20 times the normal limit. Other muscle enzymes, such as aldolase, may also be elevated. If your CK levels are elevated, your doctor may suggest genetic testing. This test looks for mutations in the dystrophin gene, which is the most common cause of DMD. It’s a simple test done by taking a blood or saliva sample. [17]
In some cases, your doctor might also recommend a muscle biopsy, where a small sample of muscle tissue is taken to look for the presence of dystrophin protein. This is less common now, as genetic testing is usually enough to confirm DMD. If needed, imaging tests like MRI can also help your doctor assess the extent of muscle damage. [1]
Currently, there is no cure for DMD, but it can be managed symptomatically with medications and surgery in some cases.
Glucocorticoids reduce the rate of muscle damage. Prednisone and deflazacort have been shown to prolong ambulation and delay the onset of secondary complications. Prednisone is used in patients over four years of age whose muscle function is declining. Deflazacort is another alternative with a better side effect profile. The major side effects of glucocorticoids include weight gain, bone mineralization, and behavioral changes. [18, 19]
Angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), and beta-blockers are used to manage cardiomyopathy. These agents prevent the onset of heart failure. Overt cases of heart failure are managed with digoxin and diuretics. [20]
Physiotherapy is the first choice for weakness. Physiotherapy options are based on the patient’s requirements. In advanced cases with contractures, surgery is suggested. Surgery is also used to correct scoliosis and improve pulmonary function.
Emerging therapies for DMD offer new hope by targeting the root cause of the condition, mutations in the dystrophin gene. Gene therapy is a promising area where scientists aim to deliver healthy copies of the dystrophin gene to muscle cells, helping them produce the protein needed to strengthen muscles. Another exciting approach is exon skipping, a technique using specialized medicines to skip over faulty parts of the gene, allowing the body to create a functional, though shorter, version of dystrophin. Other treatments focus on reducing inflammation and protecting muscle tissue from further damage, such as medications targeting specific proteins or pathways involved in muscle breakdown. These therapies are still being studied in clinical trials, but they represent a big step forward in improving the lives of individuals with DMD. [19]
The prognosis for DMD has improved over the years due to advances in medical care, but it remains a serious and life-limiting condition. DMD is a progressive disease, meaning it worsens over time as muscle weakness spreads throughout the body. Most children with DMD lose the ability to walk usually by the age of 12, the onset of scoliosis around 14 years. They may face complications such as heart and lung problems needing ventilatory support by late teens. The most common causes of death in individuals with DMD are respiratory failure and heart failure due to the weakening of the muscles involved in breathing and heart function. With proper medical management, including physical therapy, many individuals with DMD can live into their 20s or 30s, and some even longer. [21]
DMD cannot be entirely prevented because it is caused by genetic mutations, and about a third of cases happen randomly without a family history of the condition. However, genetic counseling and testing can help identify if you or your partner are carriers of the gene before planning a family. This can help assess the risk of passing the condition on to your child. For families with a history of DMD, prenatal testing or preimplantation genetic diagnosis during in-vitro fertilization can detect the mutation early. [21]
Guillain-Barré syndrome (GBS) is a neurological condition where the immune system mistakenly attacks the peripheral nervous system, [1] which consists of nerves connecting the brain and spinal cord to the rest of the body. [2] GBS often follows a respiratory or gastrointestinal infection, commonly triggered by a bacteria named Campylobacter jejuni, though other organisms are also involved.[3]
Nerves have a central core called the axon, surrounded by a protective myelin sheath that speeds up nerve signals. In GBS, the immune system attacks and damages the myelin and sometimes the axons, causing rapid nerve damage. This disrupts communication between the brain and body over hours, days, or weeks, causing pain, numbness, and muscle weakness. [4]
GBS can affect anyone, but it is slightly more common in adults and men. However, depending on other risk factors, it can also occur in children. [5]
GBS has several types, each with distinct features. The most common type, Acute Inflammatory Demyelinating Polyneuropathy, starts with sudden leg weakness that can spread to your arms and face. [6] It is more common in East Asia. [7] Other types can affect movement, sensation, or coordination. [8] Some may target the muscles around your eyes, while others might cause weakness in your throat, neck, or upper arms. Each type varies in how it impacts your body. [9, 10, 11]
The exact causes of Guillain-Barré syndrome are unclear, but it likely involves an autoimmune reaction triggered by various factors:
Guillain-Barré Syndrome often follows respiratory illnesses or stomach infections. Common triggers include the flu, Epstein-Barr virus, or Campylobacter jejuni bacteria, which is found in undercooked poultry. [12] These infections can confuse your immune system, leading it to mistakenly attack your nerves. [13, 14]
Sometimes, surgery or trauma can trigger GBS, especially when it affects your nerves. This may happen because the body’s immune system becomes highly active during recovery and mistakenly targets nerve tissue. [15]
In rare cases, certain vaccines, such as the flu vaccine, rabies, meningococcal disease, and COVID-19 vaccine, may be linked to Guillain-Barré Syndrome. While this connection is very uncommon, it’s thought that vaccines might trigger an overactive immune response in some individuals. [16, 17, 18]
Guillain-Barré syndrome (GBS) symptoms usually begin 1-3 weeks after an infection. They get worse over 2-4 weeks, then stay the same for a while before gradually improving. [19] Common symptoms include:
You may experience sudden weakness that starts in your legs and moves up to your arms and face. In severe cases, this can lead to complete muscle paralysis. You might also feel tingling or a pins-and-needles sensation, usually starting in your toes and fingers and spreading upward. [20] You might find it hard to smile or shut your eyes tightly, especially if both sides of your face are affected.
You might feel pain in your lower back and legs, with burning, tingling, or shock-like sensations in your arms and legs. This pain often starts early, sometimes before muscle weakness, and can spread to your upper body as the condition worsens. Some people find the pain very distressing or even excruciating, and it may be severe enough to need strong painkillers like opioids. [21]
You may have trouble swallowing food and drinks, which can cause choking or a feeling that something is stuck in your throat. Your speech might be slurred or unclear, making it hard for others to understand you. [22]
GBS commonly causes coordination problems and a wobbly feeling. It can also affect automatic body functions, like blood pressure and heart rhythm, which can be serious. Some people may experience weak breathing muscles and might need a ventilator.
Diagnosing GBS can be tricky because its symptoms are similar to other conditions.
Blood work can rule out other conditions that mimic GBS, such as infections or metabolic disorders, but it doesn’t directly diagnose the syndrome.
It checks how well nerves send signals. In GBS, damaged nerves send signals more slowly because the myelin sheath is damaged. [23]
In this test, a small amount of fluid is taken from your spinal cord. The fluid is called cerebrospinal fluid. This fluid is then tested to see if the results are consistent with GBS. If you have GBS, the fluid usually shows higher protein levels without an increase in white blood cells. This is a key diagnostic clue. [24]
Anti-ganglioside antibodies in GBS help identify specific antibodies that attack gangliosides. Gangliosides are molecules found in the nervous system, and their role is connected to the onset of GBS. [25]
Sometimes, a nerve ultrasound or an MRI scan of the spinal cord or brain can help determine if something else is causing muscle weakness. [26]
Currently, there is no cure for GBS, but treatments can lessen its severity and speed up recovery. There are two main treatments to stop nerve damage caused by the immune system:
Plasma exchange is a useful treatment for GBS, especially for those with moderate to severe cases. This treatment involves removing plasma (the liquid part of your blood) and replacing it with a substitute like albumin or fresh frozen plasma. It helps by removing harmful antibodies attacking your nerves, reducing inflammation, and potentially speeding recovery. [27]
IVIG is a treatment where healthy antibodies are given through a vein to neutralize the harmful ones attacking your nerves. It is often as effective as plasma exchange and easier to administer. [28]
While most people with GBS recover well, some may have lasting effects. Studies show that many patients are symptom-free within a few years, but up to 20-40% may still experience weakness, pain, or fatigue. [29] Although the risk of death is low, outcomes can be influenced by factors like age, early severe symptoms, and the need for a ventilator. Long-term quality of life might be affected, especially for those who need intensive care. Children usually recover with minor issues, but severe cases can impact their daily life and development. [30]
Close monitoring and support are essential in GBS, especially in the early stages. Breathing support is often a priority because GBS can weaken the muscles you use to breathe. In severe cases, a ventilator might temporarily help you breathe until your muscles regain strength. Heart rate and blood pressure may also need to be monitored closely, as GBS can affect your nervous system, leading to sudden changes. If swallowing becomes difficult, a feeding tube might be used to ensure you get the nutrition your body needs during recovery. [31]
As you stabilize, care focuses on helping you regain strength and independence. Physical therapy plays a big role in rebuilding your muscles and improving mobility. Eating and drinking are also important as you recover, and you might need to work with a speech therapist if swallowing remains a challenge. Emotional support is just as crucial. GBS can be overwhelming, and talking to a counselor or joining a support group can help you cope with the physical and emotional effects. [31]
GBS can lead to various complications in different parts of the body:
Around 20-30% of patients may need a ventilator to help them breathe because their breathing muscles are weak. Trouble swallowing can also cause pneumonia from food or liquid entering the lungs. [32]
Nervous system issues can change blood pressure and heart rhythm, which can be life-threatening. [33]
Some patients may have long-lasting muscle weakness that affects their ability to move. Sensory problems like tingling or pain can also continue and may need ongoing care. [32]
Many patients may still have trouble walking independently after six months. Ongoing fatigue is common and can affect daily activities. The stress of long-term disability and pain can also cause depression and lower quality of life. [34]
Pulmonary hypertension occurs when the blood pressure in the pulmonary arteries is higher than it should be. [1] These arteries carry blood from your heart to the lungs to get oxygen. When they are too narrow, the heart has to work harder to push blood through them. Over time, this extra work can weaken the heart. [2,3]
Pulmonary hypertension can be caused by other diseases, such as Chronic Obstructive Pulmonary Disease (COPD), heart disease, or conditions like blood clots in the lungs. Oftentimes, the cause of pulmonary hypertension is unknown and is called idiopathic pulmonary hypertension. [4]
Pulmonary hypertension is grouped into five main types based on its underlying cause.
Pulmonary hypertension can develop due to various underlying conditions, including:
If someone in your family has pulmonary hypertension, you might be at a higher risk due to genetic factors. Genes like BMPR2 are linked to an increased risk of PAH and can run in families. [7]
Conditions that affect the left side of your heart, like heart valve problems or heart failure, can increase pressure in the blood vessels of your lungs over time, leading to pulmonary hypertension. Structural heart defects present from birth can also increase blood flow and pressure in your lungs, causing pulmonary hypertension. These defects include left to right shunt defects or left heart obstructive lesions such as ventricular septal defect (VSD), atrial septal defect (ASD), and persistent ductus arteriosus (PDA). [8, 9]
Chronic lung problems such as COPD, interstitial lung disease, or sleep apnea can damage your lungs and make it harder for blood to flow through, raising the risk. [10]
A history of blood clots blocking the arteries in your lungs can lead to chronic high blood pressure in the lung’s vessels, especially if left untreated. [11]
Conditions like scleroderma, lupus, or rheumatoid arthritis can cause inflammation and damage to your lungs and blood vessels, increasing the chances of pulmonary hypertension. [12]
Severe liver conditions, like cirrhosis, can affect blood flow in your body and lead to increased pressure in your lung arteries, a condition known as portopulmonary hypertension. [13]
Using illegal drugs like methamphetamines or certain chemotherapy drugs has been linked to the development of pulmonary hypertension. [14]
If you live at a high elevation for an extended time, the lower oxygen levels can strain your lungs and increase the risk of developing pulmonary hypertension. [15, 16, 17]
Pulmonary hypertension can present with no symptoms, particularly in its early stages. This asymptomatic presentation can lead to delayed diagnosis. For instance, individuals with heritable pulmonary arterial hypertension may report no symptoms, and the condition might be suspected incidentally due to abnormal findings on physical examination on a routine doctor’s visit. The nonspecific symptoms of pulmonary hypertension, such as exertional dyspnea and fatigue, contribute to the diagnostic challenge, and some patients may remain asymptomatic until the disease progresses. Some common symptoms of pulmonary hypertension are as follows:
You might notice that you get out of breath easily, especially when climbing stairs or walking short distances. Over time, this can happen even while you’re resting. [18]
Feeling drained is common because your heart and lungs work harder to pump blood. About 57% of patients with pulmonary hypertension experience significant fatigue, which is the second most debilitating symptom. [19]
You may feel pressure or discomfort in your chest, especially during physical activity. This can be similar to the angina and compression of one of the arteries supplying the heart, which is found to be the cause of such pain. [20, 21]
Your ankles, legs, or even your belly might swell. This happens because your heart struggles to pump blood effectively, causing fluid buildup. [21]
You might feel lightheaded or even faint, particularly when you’re active. This occurs because your brain isn’t getting enough blood flow. [22]
You may feel like your heart is racing, fluttering, or skipping beats due to the strain on your heart. [21]
This is one of the symptoms caused by the compression of your airway by the dilated pulmonary arteries. This cough is generally persistent and increases with time. [23]
Key Diagnostic Tests for Pulmonary Hypertension are:
Pulmonary hypertension is not linked to any particular abnormalities in your blood. However, the stretch on your heart might increase brain natriuretic peptide (BNP) levels, which can also be elevated in other conditions. [24]
A chest X-ray provides a simple way to examine your heart and lungs. In pulmonary hypertension, the pulmonary arteries may appear enlarged, and the right side of the heart may look bigger. It can also help identify other lung conditions, such as interstitial lung disease or scarring, which might contribute to your symptoms. [25]
An ECG records the electrical activity of your heart. It’s a quick and painless test that can detect signs of strain on the right side of your heart caused by increased pressure in the pulmonary arteries. Your doctor will look for abnormalities, such as changes in heart rhythm or evidence of an enlarged right ventricle. [26]
This test is a key step in diagnosing pulmonary hypertension. It uses sound waves to create moving images of your heart. The echocardiogram helps your doctor estimate the pressure in your pulmonary arteries and assess how well your heart is pumping. It can also reveal structural abnormalities, such as thickened heart walls or valve problems, which can occur in pulmonary hypertension. [26]
Advanced imaging techniques like CT or MRI provide detailed pictures of your heart and lungs. A CT scan can detect blood clots in your lungs or structural abnormalities, while an MRI can provide a more detailed look at the heart’s structure and function. They also help to create a baseline assessment of the disease severity. [26, 27]
A VQ scan, or ventilation-perfusion scan, is a test that helps diagnose pulmonary hypertension, especially when caused by CTEPH. It has two parts: inhale a harmless gas to check how air moves through your lungs (ventilation), and a small tracer is injected into your vein to track blood flow (perfusion). Comparing these scans helps identify blocked blood flow areas that may point to clots. [28, 29]
This is the gold standard for diagnosing pulmonary hypertension. A thin tube (catheter) is inserted into a vein in your neck or groin and guided to your heart and pulmonary arteries. This procedure directly measures the pressure in your pulmonary arteries and assesses how well your heart functions. It also tests how your heart responds to medications or other treatments. [30, 31]
This test measures how well the lungs work and helps identify any lung diseases that might contribute to or occur alongside PH. [32]
This test measures how far a person can walk in six minutes. It’s a simple way to evaluate exercise tolerance and how well the lungs and heart work together. [33]
Pulmonary hypertension (PH) is a chronic and potentially life-threatening condition that requires a comprehensive treatment approach. Treatment strategies vary based on the underlying cause and severity of PH, and they typically include medications, lifestyle modifications, and in some cases, surgical interventions.
Medications are the main treatment for pulmonary hypertension. These can include vasodilators, which relax and widen blood vessels, improving blood flow and reducing pressure in the lungs. [34] Drugs like prostacyclins, endothelin receptor antagonists, and phosphodiesterase-5 inhibitors may be used to help lower pulmonary artery pressure. [35] Diuretics are also prescribed to reduce fluid buildup in the body, which can relieve symptoms like swelling and difficulty breathing. Additionally, blood thinners (anticoagulants) may be recommended to prevent blood clots, especially in Chronic thromboembolic pulmonary hypertension (CTEPH) cases. [36]
For patients with low oxygen levels, oxygen therapy can help improve breathing and reduce the strain on the heart and lungs. It involves using a portable oxygen tank or concentrator to provide supplemental oxygen, particularly during physical activity or sleeping. This treatment can prevent complications related to low oxygen, such as fatigue, dizziness, and organ damage. [37]
While medications are essential, lifestyle adjustments can also support treatment. A low-sodium diet helps prevent fluid retention, which can worsen symptoms of PH. Regular but light exercise can improve cardiovascular health and help manage symptoms. Avoiding high altitudes is also important because the lower oxygen levels at high altitudes can exacerbate breathing problems and increase stress on the heart. [38]
In severe cases of pulmonary hypertension that do not respond to medications, surgical treatments may be necessary. Atrial septostomy is a procedure that creates a hole between the heart’s chambers to relieve pressure in the lungs, helping improve blood flow. [39, 40] For patients with CTEPH, surgery to remove blood clots or a pulmonary thromboendarterectomy may be an option. In the most severe cases, a lung transplant may be considered when other treatments are no longer effective. [41]
Treating the underlying condition is vital if pulmonary hypertension is secondary to another disease. For instance, managing heart diseases like left-sided heart failure or lung conditions such as COPD can significantly impact pulmonary hypertension. Additionally, treating conditions like autoimmune diseases or infections can help control pulmonary hypertension symptoms and prevent further complications. [42]
Pulmonary hypertension can lead to several serious complications if left untreated. As the pressure in the lungs’ blood vessels increases, the heart has to work harder to pump blood through the lungs, which can cause the right side of the heart to enlarge and weaken, a condition known as right heart failure. [7] Additionally, pulmonary hypertension can increase the risk of blood clots, leading to a higher chance of stroke or other clot-related issues. [4] In severe cases, it can cause organ damage due to reduced oxygen levels in the body. Left untreated, pulmonary hypertension can significantly impact the quality of life and shorten life expectancy.
Pregnancy and pulmonary hypertension can be a risky combination because of the strain pregnancy places on your heart and lungs. Pulmonary hypertension causes high blood pressure in the blood vessels of your lungs, which forces your heart to work much harder to pump blood. During pregnancy, the body’s blood volume increases significantly, further stressing your heart and lungs. This can lead to serious complications such as heart failure, arrhythmias, or low oxygen levels, both for you and your baby. Pregnancy in women with pulmonary hypertension is associated with high maternal and fetal risks, and careful management by a multidisciplinary team is essential to mitigate these risks. [43]
