Symptoms of pulmonary hypertension (PH) vary in each individual and by how advanced the condition is. In less advanced functional classes of PH, there may not be any symptoms. As damage progresses, symptoms can become debilitating, forcing those with PH to significantly limit their activities. Symptoms of PH are similar across different types of PH.
PH treatments can improve symptoms and slow the progress of the disease in many people with the condition.
People with PH may not experience every symptom.
Most people with PH may experience shortness of breath or trouble breathing. You may notice breathing difficulties only with exertion, or even at rest. You may feel lightheaded or dizzy, like you are going to faint. You may even faint. A dry or persistent cough may also be a symptom of PH. In advanced PH, coughing may bring up blood. Some people with PH may experience respiratory infections or vocal changes.
Angina (chest pain), pressure, and discomfort are common in people with PH. Pain can sometimes be felt in the right upper abdomen. Some people with PH may experience leg cramps.
Fatigue is a common and debilitating symptom of PH. The heart is working harder than ever, but the body may not be receiving enough blood and oxygen. You may feel especially tired after exercise or exertion.
If your skin is not receiving enough blood or oxygen, it may appear pale grey or blue, especially your lips and nails. This discoloration is called cyanosis. Some people with PH develop Raynaud's phenomenon, a condition involving the small blood vessels of the fingers that can cause them to turn red, white, blue, or a combination of these colors. Cold temperatures sometimes cause color changes in those with Raynaud's phenomenon.
If your heart is having trouble pumping blood around your body, you may notice edema (swelling) in the legs, abdomen, or around the eyes. Edema in the abdomen is also referred to as ascites. Edema may also occur in the hands, ankles, or feet.
Cognitive changes, often referred to collectively as “cog fog” or “brain fog,” can include problems with memory, focus, paying attention, processing information, forgetting or confusing words, learning and remembering new things, organization, and getting lost in familiar places.
Depression, anxiety, and insomnia are common in those with PH, as with all chronic illnesses.
People with some types of PH may experience heart palpitations or changes in the heart rate.
PH can cause serious complications. The pulmonary artery may dilate (widen) and put pressure on the coronary artery that supplies the heart muscle itself with blood. Compression of the coronary artery can result in angina (chest pain), myocardial infarction (MI or heart attack), or sudden death. Dilation of the pulmonary arteries can also cause compression of the airways, leading to coughing and wheezing that sound like asthma. Rarely, the pulmonary artery may rupture — usually a fatal complication.
Other dangerous pulmonary (lung) complications in PH can include bleeding and the formation of blood clots.
PH can cause heart failure, also known as congestive heart failure (CHF). Heart failure is not a specific heart disease, but rather an advanced state of heart disease when the heart can no longer supply enough blood and oxygen to keep all the tissues of the body healthy.
Approximately half of the people with PH develop pericardial effusion — excess fluid in the protective sac that surrounds the heart. If too much fluid builds up, it can exert pressure on the heart that makes it difficult to beat, a life-threatening condition called cardiac tamponade.
People with PH can develop arrhythmia, or abnormal heart rhythm. Some types of arrhythmia are potentially fatal.
Some people with PH have a greater risk for developing severe pneumonia and other serious lung infections. Those who have central venous catheter lines for the infusion of medication can develop dangerous infections due to pathogens introduced via the line.
PH can cause liver damage known as cardiac cirrhosis.
