Hypertrophy may occur as the result of normal physiologic or abnormal pathologic conditions. The
increase in muscle mass associated with exercise is an example of physiologic hypertrophy. Pathologic

urinary outflow and the myocardial hypertrophy that results from valvular heart disease or hypertension.
What is compensatory hypertrophy?
