Question

Which is a characteristic of dilated cardiomyopathy?

a. Results from replacement of myocardial tissue with fibrous tissue
b. Causes stiff ventricles that restrict filling during diastole
c. Causes symptoms of left ventricular failure
d. Causes a stiff left ventricle

Answer 1

Dilated cardiomyopathy is characterized by a weakened and enlarged left ventricle, causing symptoms of left ventricular failure.

Step-by-step explanation:

Dilated cardiomyopathy is characterized by a weakened and enlarged heart chamber, specifically the left ventricle. It is caused by the stretching and thinning of the heart muscle, which impairs its ability to pump blood effectively. This leads to symptoms of left ventricular failure, such as shortness of breath, fatigue, and fluid buildup in the lungs and extremities.
