Arrhythmias and bundle branch blocks of the heart Blood clots in the pulmonary arteries Bleeding in the lungs, which may be life-threatening Heart failure, especially right ventricular failure Liver damage from increased pressure in the right heart Pericardial effusion , which is a collection of fluid in the sac-like structure around the heart Pregnancy complications that can be life-threatening for the mother and baby Look for - Pulmonary Hypertension Diagnosis will discuss tests and procedures used to detect signs of pulmonary hypertension and help rule out other conditions that may mimic pulmonary hypertension.
Treatment will discuss treatment-related complications or side effects. Diagnosis - Pulmonary Hypertension To diagnose pulmonary hypertension, your doctor may ask you questions about your medical history and do a physical exam. Your doctor may also test you for pulmonary hypertension based on your signs and symptoms and risk factors. A diagnosis of pulmonary hypertension will be made if tests show higher-than-normal pressure in the pulmonary arteries. Confirming high pressures in the pulmonary arteries - Pulmonary Hypertension Normal pressure in the pulmonary arteries is between 11 and 20 millimeters of mercury mm Hg when measured by cardiac catheterization.
Your doctor may perform the following tests to confirm high pressures in the pulmonary arteries. Cardiac catheterization to provide a definite diagnosis of pulmonary hypertension. A diagnosis of pulmonary hypertension is made if the pulmonary artery pressure is 25 mm Hg or greater while at rest. Echocardiography to estimate pulmonary artery pressure. An estimated pulmonary artery pressure of 35 to 40 mm Hg or greater on echocardiography suggests pulmonary hypertension.
A diagnosis of pulmonary hypertension may be made when enough changes are seen on an echocardiogram. If the echocardiogram suggests pulmonary hypertension, then right heart catheterization may be the next step. Medical history and physical exam - Pulmonary Hypertension Your doctor may ask you about any signs and symptoms you have been experiencing and any risk factors such as other medical conditions you have. Your doctor will also perform a physical exam to look for signs that may help diagnose your condition.
As part of this exam, your doctor may do the following: Check whether the oxygen levels in your blood are low. This may be done by pulse oximetry, in which a probe is placed on your finger to check your oxygen levels. Feel your liver to see if it is larger than normal. Listen to your heart to see if there are changes in how it sounds, and also to find out if your heartbeat is faster than normal or irregular or if you have a new heart murmur.
Listen to your lungs for sounds that could be caused by heart failure or interstitial lung disease. Look at the veins in your neck to see if they are larger than normal. Look for swelling in your abdomen and legs that may be caused by fluid buildup. Measure your blood pressure. Blood tests to look for increased risk of blood clots, stress on the heart, or anemia. Cardiac MRI to get detailed pictures of the structure and functioning of the heart and surrounding blood vessels.
Chest X-ray to look at the size and shape of the heart and surrounding blood vessels, including the pulmonary arteries. You may still have pulmonary hypertension if you have a normal ECG. Tests for other medical conditions - Pulmonary Hypertension Your doctor may order additional tests to see whether another condition or medicine may be causing your pulmonary hypertension. Doctors can use this information to develop your treatment plan. Reminders - Pulmonary Hypertension Return to Risk Factors to review family history, medical conditions, or other factors that increase your risk of developing pulmonary hypertension.
Return to Signs, Symptoms, and Complications to review common signs and symptoms of pulmonary hypertension. Treatment - Pulmonary Hypertension If you are diagnosed with pulmonary hypertension, your doctor will determine your treatment plan based on the cause of disease, if it is known. Your doctor may recommend healthy lifestyle changes, medicines, or other treatments aimed at keeping your symptoms from getting worse, increasing your ability to exercise, improving heart function, and ensuring a better quality of life.
There is no cure for pulmonary hypertension unless chronic blood clots in the lungs are the cause. Healthy lifestyle changes - Pulmonary Hypertension Depending on the cause of your pulmonary hypertension, your doctor may recommend healthy lifestyle changes. Heart-healthy eating , which includes eating less salt, to lower blood pressure or cholesterol if high levels of these contributed to the cause of your pulmonary hypertension.
Eating less salt will help control your body fluids and may improve heart function. Physical activity as recommended and supervised by your doctor Physical rehabilitation to improve your ability to exercise and also boost your quality of life Medicines - Pulmonary Hypertension Medicines to treat pulmonary hypertension may include: Anticoagulation or blood thinners to prevent blood clots in people whose pulmonary hypertension is caused by chronic blood clots in the lungs.
These thinners also can help some people who have pulmonary arterial hypertension, heart failure, or other risk factors for blood clots. Digitalis, or digoxin to control the rate blood is pumped throughout the body.
Vasodilator therapy to relax blood vessels and lower blood pressure in the pulmonary artery most affected in people who have pulmonary arterial hypertension.
This includes calcium channel blockers such as nifedipine and diltiazem, as well as newer groups of medicines called endothelin receptor antagonists and phosphodiesterase type 5 inhibitors.
Procedures and therapies Your doctor may recommend a procedure, surgery, or therapy to treat pulmonary hypertension. Oxygen therapy if oxygen levels in the blood are too low. Balloon atrial septostomy to decrease pressure in the right heart chambers and improve the output of the left heart and oxygenation of the blood. In this procedure, a small hole is made in the wall between the right and left atria to allow blood to flow from the right to the left atrium.
Balloon pulmonary angioplasty to lower the blood pressure in your pulmonary artery and improve heart function in people who cannot have a pulmonary endarterectomy. Pulmonary endarterectomy surgery to remove blood clots from the inside of the blood vessels of the lungs. Treatments for other conditions - Pulmonary Hypertension Your doctor may recommend medicines or procedures to treat the condition that is causing your pulmonary hypertension. Blood pressure medicines such as angiotensin-converting enzymes inhibitors, beta blockers, or calcium channel blockers when left heart disease is the cause Blood transfusions or hydroxyurea to treat sickle cell disease Heart valve repair Iron supplements to increase blood iron levels and improve anemia Look for - Pulmonary Hypertension Research for Your Health will discuss how we are using current research and advancing research to treat people with pulmonary hypertension.
Participate in NHLBI Clinical Trials will discuss our open and enrolling clinical studies that are investigating treatments for pulmonary hypertension.
Living With will discuss what your doctor may recommend, including lifelong lifestyle changes and medical care to prevent your condition from recurring, getting worse, or causing complications.
Living With - Pulmonary Hypertension After you are diagnosed with pulmonary hypertension, it is important to follow your treatment plan, get regular care, and learn how to monitor your condition.
Taking these steps can slow down the progression of the disease and may improve your condition. Your specific treatment plan will depend on the cause of your pulmonary hypertension, as well as how advanced it is. Receive routine follow-up care - Pulmonary Hypertension Your follow-up care may include recommendations such as these: Participate in support groups, counseling, and education efforts that can help you manage the activities of daily living, experience a successful pregnancy, and generally improve the quality of your life.
Get the recommended vaccines, which often include a vaccine for pneumococcus and an influenza, or flu, shot every year at the start of flu season. Return to Treatment to review possible treatment options for your pulmonary hypertension. Monitor your condition - Pulmonary Hypertension Talk to your doctor about new or concerning symptoms.
People who have pulmonary hypertension may need regular tests. Prevent complications over your lifetime - Pulmonary Hypertension To help prevent some of the complications of pulmonary hypertension, your doctor may recommend the following. Make heart-healthy lifestyle changes such as heart-healthy eating if your pulmonary hypertension is due to heart failure from ischemic heart disease or high blood pressure.
Engage in regular physical activity. Before starting any exercise program, ask your doctor about what level of physical activity is right for you. Avoid high altitudes when possible and discuss with your doctor any plans for air travel or visits to places at high altitude.
Talk to your doctor if you are planning to get pregnant, as there is an increased risk of pregnancy complications. Treat other medical conditions, such as COPD, heart conditions, and sleep apnea. Learn the warning signs of serious complications and have a plan - Pulmonary Hypertension Even with treatment, pulmonary hypertension may lead to serious complications such as heart failure and arrhythmias.
Know the signs and symptoms of pulmonary hypertension and how to recognize the possible complications. If you are taking a blood thinner, this will increase your risk of bleeding. If you experience any abnormal bleeding, such as blood in your stool, black stool, or coughing up blood, contact your doctor right away.
If you fall while taking a blood thinner, you are at higher risk for bleeding inside your head. Let your doctor know if you have fallen while taking a blood thinner. Some treatments for pulmonary hypertension must be given through a long-term intravenous IV line. Call your doctor right away if you have any signs of infection.
Signs of infection include redness, swelling, or yellow discharge where the IV is inserted; a fever of We are committed to advancing science and translating discoveries into clinical practice to promote the prevention and treatment of heart, lung, blood, and sleep disorders, including pulmonary hypertension.
Learn about the current and future NHLBI efforts to improve health through research and scientific discovery.
Improving health with current research - Pulmonary Hypertension Learn about the following ways the NHLBI continues to translate current research into improved health for people with pulmonary hypertension.
VITA seeks to address unmet clinical needs for vascular diseases, particularly in underserved medical communities. The NHLBI and the Cardiovascular Medical Research and Education Fund held a workshop that addressed multiple topics that are central to the development of true personalized medicine in pulmonary vascular disease, including pulmonary hypertension. The workshop also identified needs and made recommendations to the NHLBI for future research priorities in this area.
Researchers in this program have discovered a new way to stop and potentially reverse the changes that occur with pulmonary hypertension through the use of antibodies that target two proteins which contribute to the disease.
