Abstract:
Objective: To observe the changes of left ventricular (LV) systolic strain(e) and strain rate(SR) in patients with hypertrophic cardiomyopathy (HCM) and normal healthy subjects by velocity vector imaging(VVI). Methods: Twenty patients with HCM and 20 age-matched healthy adults were enrolled in this study. The peak systolic ε, SR of 18 segments in the 4,3 and 2-chamber views were measured by VVI. Results: It was found that the systolic SR was (- 1.06±0.09)/s in the healthy control group and (- 0.74±0.16)/s in the HCM group(P
