Which term denotes disease of the heart muscle?

• A. Cardiomyopathy
• B. Cardiology
• C. Cardiac
• D. Cephalic

Answer: (A)

This question tests how word parts combine to give a precise meaning. Cardiomyopathy breaks down into cardio- meaning heart and myopathy meaning disease of muscle, so it literally names a disease of the heart muscle. That specificity makes it the term that fits. The other options don’t denote a disease of the heart muscle: cardiology is the medical field that studies the heart, cardiac is an adjective relating to the heart, and cephalic means relating to the head.
