Shortness of breath that won’t quit, tiredness after small tasks, or fainting spells—these can be signs of pulmonary hypertension (PH). PH means high blood pressure in the arteries that carry blood from your heart to your lungs. That extra pressure strains the right side of the heart and makes breathing feel hard. If you notice these symptoms, bring them up with your doctor; early action matters.
How do doctors check for PH? Most often they start with an echocardiogram (ultrasound of the heart). If that suggests PH, a right heart catheterization is the test that confirms it and measures pressures directly. Other tests often include blood work, lung function tests, and a CT scan to look for causes like lung disease or blood clots.
Treatment aims to lower pressure in the lung vessels, ease symptoms, and protect the heart. Your doctor may recommend one or more drug classes: vasodilators (prostacyclin analogs), endothelin receptor antagonists, PDE5 inhibitors, or newer drugs like soluble guanylate cyclase stimulators. Some people benefit from oxygen, diuretics to reduce fluid, or blood thinners in specific situations. A small group responds to calcium channel blockers after a vasoreactivity test.
Medications can work well but often need careful monitoring. Side effects, interactions, and dosing matter. For example, potassium-sparing diuretics like spironolactone can raise potassium—mixing alcohol or other meds can make that worse. Talk openly with your clinician about side effects and about other medicines you take, including supplements.
Track your symptoms: note walking distance, climb count, and any chest pain or dizziness. Cut down on salt to help control fluid buildup. Keep up with vaccinations (flu, COVID, pneumonia) to avoid lung infections that can worsen PH. Plan activity—short walks and breaks work better than pushing through heavy exercise. If you’re pregnant or planning pregnancy, discuss risks with your specialist—PH can raise complications and needs expert care.
Know when to seek help: sudden worse breath, chest pain, fainting, or swollen legs deserve urgent care. Keep a list of your medicines, doses, and allergies in your phone and share it with any clinician you see.
