Final answer:
Dilated Cardiomyopathy (option C) is the correct answer as it refers to the left ventricle of the heart being enlarged, leading to a decreased cardiac output. Other conditions such as Hypertrophic Cardiomyopathy, Restrictive Cardiomyopathy, and Ischemic Cardiomyopathy involve different mechanisms of heart malfunction.
Step-by-step explanation:
When the left ventricle of the heart becomes enlarged and causes a decrease in cardiac output, the condition is referred to as Dilated Cardiomyopathy. This condition occurs when the heart's ability to pump blood is decreased because the left ventricle is enlarged and weakened. In contrast, Hypertrophic Cardiomyopathy is characterized by the pathological enlargement or thickening of the heart muscle, generally without a known cause, leading to a reduction in the size of the ventricular cavity and potentially causing obstruction to blood flow.
Restrictive Cardiomyopathy involves the stiffening of the heart muscle, not necessarily enlargement, which restricts the heart's filling with blood. Ischemic Cardiomyopathy is caused by narrowed or blocked coronary arteries, leading to a reduced blood supply to the heart muscle and often associated with a prior heart attack or chronic coronary artery disease.
