Effects of candesartan and cilazapril on rats with myocardial infarction assessed by echocardiography.

The purpose of this study was to compare the angiotensin II type 1 receptor antagonist candesartan cilexitil (candesartan) and the angiotensin-converting enzyme inhibitor cilazapril on cardiac function, assessed by Doppler echocardiography and cardiac gene expression associated with cardiac remodeling, in rats with myocardial infarction. Candesartan or cilazapril was administered after myocardial infarction. At 1 and 4 weeks after myocardial infarction, cardiac function and mRNA expression in noninfarcted myocardium were analyzed. Candesartan and cilazapril equally prevented increases in hypertrophy in noninfarcted myocardium, left ventricular dilatation, and ejection fraction at 4 weeks. The E-wave/A-wave velocity ratio and the rate of E-wave deceleration, measures of diastolic function, increased to 9.2+/-0.6 and 26.3+/-2. 6 m/s2 at 1 week after myocardial infarction. Candesartan and cilazapril, administered at a dose of 1 mg/kg per day, prevented increases in E-wave/A-wave velocity ratio and E-wave deceleration at 1 and 4 weeks. Candesartan and cilazapril significantly suppressed increased mRNA expression of beta-myosin heavy chain, alpha-skeletal actin, and atrial natriuretic peptide in noninfarcted ventricle at 1 and 4 weeks and expression of collagen I and III at 4 weeks to a similar extent. When given at a dose of 10 mg/kg per day, both candesartan and cilazapril prevented cardiac dysfunction and gene expression to the same extent as when given at 1 mg/kg per day. In conclusion, Doppler echocardiography showed that candesartan and cilazapril equally improved systolic and diastolic function and that ventricular remodeling accompanied modulation of cardiac gene expression.[1]
