Resveratrol Suppresses Cardiac Renin Angiotensin System in the Late Phase of Left Ventricular Hypertrophy
Background and objectives: Resveratrol(3,5,4′-trihydroxy-trans-stilbene) is a natural polyphenole phytoalexin which exerts potential cardioprotective effects, but the cellular and molecular mechanisms responsible for these effects are still unknown. Cardiac renin angiotensin system (RAS) over-activation plays an important role in pathogenesis of left ventricula...
متن کاملVentricular weight in cardiac hypertrophy.
Ventricular hypertrophy is usually estimated at necropsy by weighing the heart as a whole and by measuring the thickness of the ventricular walls. The weight of the heart as a whole is open to the objection that a large and varying proportion of the weight is accounted for by structures other than the myocardium, and the thickness of the ventricular wall is not a satisfactory criterion because ...
متن کاملPotentiation of reperfusion-associated ventricular fibrillation by left ventricular hypertrophy.
Important electrophysiological alterations that may predispose hearts to arrhythmias have been described for hypertrophied myocytes, and hypertrophy coupled with ischemia has been associated with an increased incidence of sudden death; however, an influence of hypertrophy on reperfusion arrhythmias has not been previously described. We hypothesized that reperfusion-associated arrhythmias would ...
متن کاملChanges in rat ventricular isomyosins with regression of cardiac hypertrophy.
The changes in ventricular isomyosin composition and Ca2+-activated ATPase activity occurring with regression of both hypertension and cardiac hypertrophy were investigated by using polyacrylamide gel electrophoresis under nondenaturing conditions, heavy chain peptide mapping, and an enzymatic assay. Eight control male Wistar rats and 14 two-kidney, one clip (Goldblatt II) hypertensive rats wer...
متن کامل[Adenosine induces ventricular arrythmias in hearts with chronic chagas cardiomyopathy].
Adenosine released during ischemia and hypoxia can induce ventricular arrhythmias. This phenomenon is also observed in Chagas disease. This study involved pharmacologic analysis of the arrhythmogenic properties of adenosine in healthy Sprague-Dawley rats (n=14) and in rats with chronic Chagas cardiomyopathy (n=14). Electrocardiographic and pharmacologic studies were performed on isolated hearts...
