A patient is in systolic heart failure. Which description best fits the state of the left ventricle?

A. A thin and strong left ventricle is not typical of systolic heart failure. B. A thick and weak ventricle is more characteristic of diastolic heart failure (impaired relaxation and filling). C. Systolic heart failure involves impaired contraction of the left ventricle, which often becomes thin and weak due to ventricular dilation and loss of contractile strength. D. A thick and strong ventricle is not typical of heart failure.
