Living with pulmonary arterial hypertension living

Overview

Pulmonary arterial hypertension (PAH) is a rare type of high blood pressure that happens in the arteries of your lungs. These arteries carry blood from the right side of your heart to your lungs to get oxygen. In PAH, the walls of these arteries become thick and stiff, so it's harder for blood to flow. This puts extra strain on your heart, especially the right side, and can make you feel breathless and tired.

No. PAH is rare. It affects around 15 to 50 people in every million. Because it is rare, it may be missed at first, and a specialist team is usually needed.

PAH can affect people of any age, including children, but it is more often found in adults. Women are about twice as likely as men to have it. It can be inherited, run in families, or happen alongside other health conditions like connective tissue disease or congenital heart disease. Sometimes no cause is found.

Symptoms

Common symptoms

• Shortness of breath during everyday activities, like climbing stairs or walking
• Feeling tired or fatigued even after little effort
• Chest pain or pressure, especially during physical activity
• Dizziness or lightheadedness, sometimes causing fainting
• Swelling in your ankles, legs, or around your belly
• A racing or pounding heartbeat (palpitations)
• A dry cough, especially with exercise

Symptoms in children

• Your child may tire easily or not want to play as much as other kids
• They may seem more irritable than usual
• They might have trouble keeping up with friends during activities
• Slower growth or poor weight gain
• Turning blue around the lips or nails (call a doctor right away)

Symptoms in older adults

• Symptoms like breathlessness and swelling may be mistaken for normal aging or other heart/lung problems
• You may notice it's harder to carry groceries or walk longer distances
• Dizziness and falls are a concern, so talk to your doctor if these happen
• Older adults might also have other conditions that make symptoms more confusing, so a careful check-up is important

Causes

Main causes

• The exact cause is often unknown (called idiopathic PAH)
• It can be caused by gene changes that run in families (heritable PAH)
• Other health conditions can lead to PAH, such as connective tissue diseases (like scleroderma), HIV, liver disease, or congenital heart defects
• Certain medications or toxic substances, such as some appetite-suppressant drugs or illegal drugs, may trigger it

Risk factors

• Being a woman
• A family history of PAH or other related heart/lung conditions
• Having an autoimmune disease, such as lupus or rheumatoid arthritis
• Advanced liver disease called portal hypertension
• Using certain drugs or toxins that affect blood vessels
• Living at high altitude or having sleep apnea (though these are less well proven)

When to see a doctor

See a doctor urgently if:

• If you have sudden fainting, severe chest pain, or trouble breathing even at rest, call your local emergency number immediately.
• If you are coughing up blood, get emergency help right away.
• If you develop rapid swelling in your legs or belly that feels worse, seek care the same day.

Book a routine appointment if:

• If you notice increasing shortness of breath, tiredness, or dizziness during daily activities, make a doctor's appointment.
• If you have a heart or lung condition and new symptoms appear, tell your doctor.
• If you have a family member with PAH, discuss whether you need any screening tests with your doctor.

Diagnosis

Diagnosing PAH usually starts with a careful conversation about your symptoms, your health history, and a physical examination. Because PAH is rare, your doctor often needs to rule out more common causes of breathlessness first. If PAH is a possibility, you will be referred to a specialist, usually a pulmonologist (lung specialist) or a cardiologist (heart specialist), for a series of tests.

Tests that may be done

• Echocardiogram (ultrasound of the heart) to look at the heart's shape and function and estimate pressure in the lung arteries
• Right heart catheterization – a thin, flexible tube is passed into the heart and lung arteries to measure the pressure directly; this is the gold standard test
• Electrocardiogram (ECG) to check the heart's electrical activity
• Pulmonary function tests to measure how well your lungs are working
• Blood tests to check for underlying causes, anemia, or autoimmune diseases
• Chest X-ray or CT scan to look at the heart and lungs
• Sometimes, a 6-minute walk test to measure your functional capacity

What to expect at your appointment

The tests are usually done as an outpatient procedure, though some may require a short hospital stay. Right heart catheterization sounds scary, but it is done under local anesthesia, and most people go home the same day or after a few hours. Your care team will explain everything and guide you step by step. You will not be left alone to wonder what's happening.

Treatment

There is no cure for PAH yet, but treatment has improved greatly. The goal is to ease symptoms, slow down the disease, and help you feel better. Your treatment plan will be tailored to you, and you will be looked after by a specialist team. You'll have regular check-ups to monitor how you're doing and adjust treatments as needed.

Self-care at home

• Balance activity with rest – pace yourself and listen to your body
• Do light exercise like walking, stretching, or stationary cycling, but always talk to your doctor first about what is safe for you
• Avoid extreme physical exertion, heavy lifting, and intense sports unless your doctor says okay
• Stop smoking and avoid secondhand smoke
• Manage stress with relaxation techniques like deep breathing or meditation
• Weigh yourself regularly and tell your team about sudden weight gain – it may be a sign of fluid buildup
• Get enough sleep and avoid sleep deprivation

Medical treatments

Medicines for PAH work in different ways. Some relax the blood vessels in your lungs to lower pressure. Others help the heart pump better. Some are water pills (diuretics) to remove extra fluid and reduce swelling. Blood thinners may be used to lower the risk of blood clots. You may also need oxygen therapy if your blood oxygen levels are low. It is important to never start, stop, or change any medication without talking to your healthcare provider. Your doctor will explain your options, how they are taken (pill, infusion, injection, or inhaler), and what side effects to watch for.

When is surgery considered?

If other treatments are not enough, some people may be offered a procedure called a balloon atrial septostomy, which creates a small opening in the heart to ease pressure. For advanced PAH, a lung transplant or heart-lung transplant may be considered in very select cases. These are major procedures, and your specialist team will talk with you about the risks and benefits if they think this is an option for you.

Living with this condition

Living with PAH means learning to manage your energy and pace yourself. Some days will be better than others. It's helpful to plan your day, sit rather than stand when possible, and ask for help with heavy chores. Keep a symptom diary so you can talk to your care team about changes. Remember that you are an important part of your care team – your insights matter.

Lifestyle tips

• Eat a balanced diet with less salt to help reduce fluid buildup
• Stay hydrated, but follow your doctor's advice on fluid intake – some people may need to limit fluids
• Aim for a healthy weight – being overweight or underweight can affect your heart and lungs
• Avoid alcohol and illegal drugs, as they can harm your heart
• Make sure you get all recommended vaccinations, especially flu, pneumonia, and COVID-19
• Avoid high altitudes – talk to your doctor before flying or traveling to high places
• If you are planning to become pregnant, discuss this with your doctor – pregnancy can be risky in PAH

Diet and exercise

Eating well is an important part of feeling strong. A low-salt diet helps control swelling. Your doctor or a dietitian can give you advice. For exercise, gentle activity is usually encouraged, but always check with your healthcare provider first. Many people with PAH benefit from pulmonary rehabilitation – a supervised exercise and education program designed for lung conditions. Stop exercise if you feel very breathless, dizzy, or pain in your chest.

Mental health and emotional wellbeing

Living with a chronic condition can bring up many emotions – anxiety, sadness, frustration, or even worry about the future. These feelings are completely normal. It's important to talk about them, whether with your doctor, a counsellor, or a trusted friend or family member. Taking care of your mental health is just as important as taking care of your physical health. If you ever feel overwhelmed, please talk to someone. Looking after your mental well-being helps you live better with PAH.

Prevention

For many forms of PAH, there is no known prevention because the cause is not always clear. If you have risk factors, such as a family history or a connective tissue disease, you can work with your doctor to monitor your heart and lungs closely. Avoiding smoking, staying active, and avoiding drugs that can harm your blood vessels may help reduce your risk of developing PAH or may help slow its progression.

Vaccines

Vaccines are very important for people with PAH because respiratory infections like flu and pneumonia can put extra strain on your heart and lungs. Make sure you're up to date with your seasonal flu vaccine, pneumonia vaccine, and COVID-19 vaccine. Talk to your doctor about which vaccines are recommended for you.

Screening programmes

Routine screening for PAH is not recommended for everyone. But if you have a family member with PAH or a condition that puts you at higher risk (like scleroderma), your doctor may suggest regular echocardiograms to check your heart. If you have symptoms, screening can help find PAH early, when treatment is most effective.

Complications

If left untreated

• The right side of your heart can enlarge and weaken over time (right heart failure)
• Irregular heart rhythms (arrhythmias)
• Blood clots in the lung arteries
• Bleeding in the lungs
• Fainting episodes
• Difficulty doing everyday tasks due to breathlessness and fatigue

Long-term outlook

A diagnosis of PAH can feel overwhelming, but there is real cause for hope. Treatments have come a long way, and many people live active, fulfilling lives for years after their diagnosis. Your outlook depends on what is causing the PAH, how severe it is, and how your body responds to treatment. With a committed medical team, healthy lifestyle choices, and strong support, you can face the road ahead with confidence. There is always something that can be done to help you feel better.
