What is heart muscle growth?

Heart muscle growth refers to the increase in the size and number of muscle cells in the heart muscle. This process, also known as cardiac hypertrophy, is a normal response to certain stimuli, such as exercise or strenuous physical activity.

Normally, the heart muscle responds to increased demands by increasing its wall thickness and the number of muscle cells. This allows it to pump more blood and meet the body's needs during physical activity. However, in some cases, such as certain heart conditions or diseases, the heart muscle can undergo abnormal or pathological hypertrophy, which can have adverse effects on heart function.
