Synopsis

Hypertrophy, dilation, or malfunction of the right ventricle as a complication of pulmonary hypertension. The chronic presentation is more common and can be caused by chronic obstructive pulmonary disease, interstitial lung diseases, pulmonary vascular diseases, or obstructive sleep apnea. The acute presentation can be caused by a sudden worsening of these diseases or by pulmonary embolism. Symptoms include chest pain, fatigue, syncope, dyspnea on exertion, cough, hypoxemia, hemoptysis, cyanosis, and peripheral edema.

Acute presentations may also present with pallor, diaphoresis, hypotension, and tachycardia. Chronic presentations are harder to detect and may present with clubbed fingernails, wheezing, crepitations, papilledema, tender hepatomegaly, and ascites. Treatment and prognosis depend on the causal underlying disease.
