[Effects of perindopril on left ventricular hypertrophy, coronary reserve and mechanical properties of the papillary muscle of the rat with renovascular arterial hypertension].

We investigate the effect of a new angiotensin-converting enzyme inhibitor: Perindopril (IRIS) on regression of left ventricular hypertrophy (LVH), coronary blood flow and mechanical performance of isolated papillary muscle in renovascular hypertensive (Goldblatt 2 kidneys-1 clip) Sprague-Dawley male rats. Sham operated rats (G1) and half of hypertensive rats (G2) were studied after 8 weeks. The other half of 8 weeks long hypertensive rats (G3) were treated during 8 weeks with Perindopril in drinking water at a dosage adjusted to maintain blood pressure (BP) measured with tail cuff method under 140 mmHg.
