Etymed
cor pulmonale
Definition
A condition where the right side of the heart becomes enlarged due to lung disease, causing the right ventricle to work harder to pump blood through the lungs
Clinical context
A 65-year-old smoker presents with progressive shortness of breath and peripheral edema. On examination, there is jugular venous distension and hepatomegaly. Echocardiogram shows right ventricular dilation and elevated pulmonary artery pressures. The patient's chronic obstructive pulmonary disease has led to increased pulmonary vascular resistance, causing right heart failure.
Mnemonic
Lung disease = Right heart failure = Cor pulmonale
