Abstract：Objective: To evaluate the left ventricular regional myocardial systolic function in patients with diastolic heart failure using real-time triplane strain rate imaging and investigate its clinical significance. Methods: Twenty-nine patients with diastolic heart failure, 26 patients with systolic heart failure and 30 healthy subjects as control group were enrolled. The systolic peak strain rate(SRs) were measured at basal and middle segments in different left ventricular walls using real-time triplane strain rate imaging. Results: SRs in diastolic heart failure and systolic heart failure groups were significantly lower than in control group(P＜0.05 or P＜0.01). There was a significantly step-down change among normal, diastolic heart failure and systolic heart failure in SRs(P＜0.05 or P＜0.01). Conclusions: The left ventricular regional myocardial systolic dysfunction existed in patients with diastolic heart failure. Thus, assessing left ventricular regional myocardial systolic function using real-time triplane strain rate imaging has important clinical value in the comprehensive evaluation of cardiac function in heart failure.
