[Effect of Kanli Granule on Myocardial Mechanics in Pressure Overload Induced Diastolic Heart Failure Rats].

Objective: To observe the effect of Kanli Granule (KG) on myocardial mechanics in pressure overload induced diastolic heart failure (DHF) rats.

Methods: Totally 60 male Wistar rats were divided into the sham-operation group, the model group, the KG group, and the Valsartan group according to random digit table, 15 in each group. The pressure overload induced DHF model was established in all groups except the sham-operation group using abdominal aortic constriction surgery.
