Effects of Qili Qiangxin Capsule on AQP2, V2R, and AT1R in Rats with Chronic Heart Failure

Typical echocardiography images from the sham group, the CHF group, the QL group, and the Valsartan group. At the 4th week of QL and Valsartan administration, cardiac structure and function were measured in each group by echocardiography. We evaluated cardiac systolic and diastolic functions by measuring the following variables: ejection fraction (EF), fractional shortening (FS), end-diastolic volume (EDV), end-systolic volume (ESV), left ventricular end-diastolic dimension (LVIDd), and left ventricular end-systolic dimension (LVIDs). Treatment with either QL or Valsartan improved systolic function. (, versus the CHF group, , versus the sham group).
