Abstract
Whenever sustained changes of activity and/or load occur all tissues of the body adapt their structural design. The hypertrophic response of skeletal muscle of athletes is an illustrative example of such an adaptative process. As a consequence of elevated arterial pressure, wall stress increases and, in an attempt to bring wall stress back to normal, the left ventricle adds contractile elements in parallel. Posterior and septal walls thicken and concentric left ventricular hypertrophy (LVH) [1] develops. Initially this increase in cardiac mass has little functional consequence; however, LVH cannot be simply considered a physiological adaptative process. In fact, it is known that, if elevated blood pressure is left untreated, the adaptative response ultimately fails, leading to heart failure. Furthermore, several epidemiological studies have demonstrated that LVH is one of the most powerful risk factors for heart attack, sudden death, and myocardial infarction [2-4]. These phenomena can be ascribed to abnormalities of myocardial structure and function associated with the development of LVH.
