Cor Pulmonale

Cor pulmonale is a medical condition in which the right ventricle of the heart becomes enlarged, weakened, and unable to effectively pump blood due to an underlying respiratory disorder. It is a form of pulmonary heart disease and is usually caused by an underlying lung condition, such as chronic obstructive pulmonary disease (COPD). The right ventricle of the heart is responsible for pumping oxygen-poor blood from the body to the lungs, where it can be oxygenated. When the respiratory disorder impairs the ability of the lungs to oxygenate the blood, the right ventricle must work harder to pump the blood, leading to increased pressure and strain on the heart. Symptoms of cor pulmonale include shortness of breath, chest pain, fatigue, and swelling in the ankles and feet. Diagnosis is made through a physical exam and tests such as an echocardiogram. Treatment typically involves managing the underlying respiratory condition and lifestyle modifications to reduce the strain on the heart.
