Abstract
The goal of the current study was to determine whether treatment of hypertension reduces cerebral infarction after occlusion of the middle cerebral artery in stroke-prone spontaneously hypertensive rats (SHRSPs). Three-month-old SHRSPs received untreated drinking water or drinking water containing cilazapril, an angiotensin converting enzyme inhibitor, or hydralazine and hydrochlorothiazide. After 3 months of treatment, the left middle cerebral artery was occluded and neurological deficit was evaluated. Infarct volume was measured 3 days after occlusion using computer imaging techniques from brain slices. Cilazapril and hydralazine with hydrochlorothiazide were equally effective in reducing systolic blood pressure in SHRSPs. One day after occlusion of the middle cerebral artery, neurological deficit was decreased by both cilazapril and hydralazine with hydrochlorothiazide compared with untreated SHRSPs, and the deficit 3 days after occlusion was decreased significantly only by cilazapril. Infarct volume was 178 +/- 7 mm3 (mean +/- SEM) in untreated SHRSPs, and it was significantly reduced to 117 +/- 15 mm3 by hydralazine with hydrochlorothiazide and to 101 +/- 17 mm3 by cilazapril. Infarct volume in Wistar-Kyoto rats was 27 +/- 16 mm3. Thus, reduction in arterial pressure by hydralazine with hydrochlorothiazide or an angiotensin converting enzyme inhibitor is protective against focal cerebral ischemia in SHRSPs.
