Description:

Left ventricular hypertrophy (LVH) is the result of interaction between a chronic hemodynamic overload and non-hemodynamic factors. There are several lines of evidence presented in this work suggesting that nitric oxide (NO) may participate in the hypertrophic growth of the myocardium. First, endothelial NO production was shown to be decreased in several types of hemodynamically overloaded circulation both in animals and humans. Second, compounds stimulating NO production were able to diminish the extent or modify the nature of LVH in some models of myocardial hypertrophic growth. Third, arterial hypertension can be induced by inhibition of nitric oxide synthase activity. This NO-deficient hypertension is associated with the development of concentric LVH, myocardial fibrosis and protein remodeling of the left ventricle. The mechanism of LVH development in NO-deficient hypertension is complex and involves decreased NO production and increased activation of the renin-angiotensin-aldosterone system. Cardiovascular protection via ACE inhibition in NO-deficient hypertension may be induced by mechanisms not involving an improvement of NO production. In conclusion, the hypertrophic growth of the LV appears to be the result of interaction of vasoconstrictive and growth stimulating effects of angiotensin II on the one hand and of vasodilating and antiproliferative effects of nitric oxide on the other., F.
