Inducible nitric oxide synthase deficiency protects the heart from systolic overload-induced ventricular hypertrophy and congestive heart failure.

abstract：:The purpose of these studies was to evaluate cardiovascular structural and functional changes in a model of hypertension-induced myocardial hypertrophy in which vasodilator therapy decreased blood pressure to normal levels. Thus, we determined the separate contributions of hypertension and hypertrophy on myocardial an...
