What causes the heart to enlarge?

A doctor has provided 1 answer

Many causes: All very fit athletes have big hearts, which is good, and all fat people have bit hearts which lets them carry the extra weight. The heart bulks like a bodybuidler's biceps when worked extra hard. High blood pressure and anemia are easy to understand, some hearts are malformed with dangerous enlargement as bumps in bad places. Many others. Clinical correlation required!
