Abstract:
Objective To evaluate the changes of the activation and proliferation of rat cardiac fibroblasts in infarcted and non-infarcted regions.Methods The model of myocardial infarction (AMI)was developed through the ligation of anterior descending branch of left coronary artery.After 24 hours,the survived 114 rats were randomly assigned to the following 2 groups:(1)AMI group (n=57);(2)telmisartan treatment group(n=57).And a sham-operated group(n=32)was used asa control.All groups were terminated at day 4,7,14,28,respectively(n=10,12,15,20).At the end of the study,heart rate(HR),blood pressure (BP),ventricle relative weight (ventricle weight/body weight,VW/BW) and survival rate were measured,and the activation and proliferation of fibroblast and collagen volume fraction (CVF) were assessed.Results (1)The 28 day accumulated survival rate for treatment group was lower than that for AMI group (P
