Cor Pulmonale
-
Pathophysiology
Pulmonary Vascular Resistance goes up due to vasoconstriction, obstruction, or alveolar distension
Blood backs up and afterload of Right Ventricle increases. Right ventricle compensates by increasing Ventricular Contractility
Chronic increase in contractility wears out the ventricle and blood continues to back up causing an increase in afterload, preload and a decrease in contractility.
