SUMMARY

Whenever the heart is challenged with an increased work load for a prolonged period, it responds by increasing its muscle mass--a phenomenon known as cardiac hypertrophy. Although cardiac hypertrophy is commonly seen under physiological conditions such as development and exercise, a wide variety of pathological situaยญ tions such as hypertension (pressure overload), valvular defects (volume overload), myocardial infarction (muscle loss), and cardiomyopathy (muscle disease) are also known to result in cardiac hypertrophy. Various hormones such as catecholamines, thyroid hormones, angiotensin II, endothelin, and growth factors have also been shown to induce cardiac hypertrophy. Although the exact mechanisms underlying or pathological forrns of cardiac hypertrophy are poorly underยญ the physiological stood, an increase in the intraventricular pressure is believed to represent the major stimulus for the development of cardiac hypertrophy. In this regard, stretching of the cardiac muscle has been shown to induce the hypertrophic response, but the role of metabolic influences in this process cannot be ruled out. Furthermore, different hormones and other interventions in the absence of stretch have been observed to stimulate protein synthesis in both isolated cardiomyocyte and vascular myocyte preparations. Nonetheless, it is becoming dear that receptor as well as phospholipidยญ linked signal transduction pathways are activated in some specific manner dependยญ ing upon the initial hypertrophic stimulus, and these then result in an increase in the size and mass of cardiomyocytes
