Is pulmonary hypertension always associated with heart failure?

No. Only when the pulmonary hypertension causes the right ventricle to dilate (enlarge) does heart failure occur. This type of failure may affect the right side of the heart causing increased leg swelling, fluid buildup in the abdomen and elevation of liver enzymes. If the swelling of the right heart becomes severe it can affect the function of the left side of the heart and cause pulmonary edema.
PH and Heart Failure. High blood pressure (BP) in the lungs is called pulmonary hypertension (ph) or pulmonary arterial hypertension (pah). Pah is a chronic and life-changing disease that can lead to right heart failure if left untreated. Many treatments are now available to prevent heart failure associated with ph.
No. The patients who develop phtn initially do not have heart failure. They have shortness of breath, fatigue, and even syncope. But heart failure develops over time in our patients with phtn and is the cause of death. Thus, patients with phtn need to be monitored closely so that if they develop heart failure, doctors can treat them quickly and increase medications.
