METHODS: Thirtysix SD female rats were randomly separated into 3 groups (n=12 in each one) according to the infarction duration (1, 3, 28 d), which were randomly and evenly again separated into 2 subgroups: operated group and sham operated group. The levels of mRNA expression of ACE2 in the noninfarct and infract area of left ventricle 1, 3, 28 d after AMI were detected by RTPCR and analyzed semiquantitatively by imageanalysis system.
