Abstract
Systolic and diastolic asynchrony is common in patients with cardiomyopathy either ischemic or non-ischemic type. Accurate assessment of this intraventricular and interventricular asynchrony is of great importance to identify the patients that will benefit from cardiac resynchronization therapy. The aim of the present study was to assess the feasibility of Doppler tissue imaging in assessment of LV asynchrony in patients with ischemic and non-ischemic cardiomyopathy and in differentiating ischemic from non- ischemic cardiomyopathy. The study included 40 patients with ischemic cardiomyopathy (24 males and 16 females) with a mean age 57.25±9 and 29 patients with dilated cardiomyopathy (16 males and 13 females) with a mean age 56.3±8.4, 15 age matched healthy volunteers served as a control group with a mean age 57.5±3.1. All patients and control groups were examined by conventional echo-Doppler study and Doppler tissue imaging technique. By taking the beginning of QRS as a reference point we measured the precontraction time (PCT), time to beginning of S wave (Sj, time to peak systolic wave (T)and time to early diastolic wave (Te). In the ischemic cardiomyopathy group, 15 patients had a wide QRS duration in the surface EGG and 25 patients had a narrow QRS. However, in the dilated cardiomyopathy group, 11 patients had a wide QRS duration in the surface EGG and 18 patients had a narrow QRS.
