Abstract

Aims: Describe Characteristics of left ventricular’s presystolic wave on echocardiography in type 2 diabetes mellitus patients. Patients and methods:  we performed a descriptive cross – sectional study included 90 patients: 60 type 2 diabetes mellitus patients and 30 healthy subjects in endocrinology department – Bach Mai hospital and Vietnam National Heart institue. The researched values included: velocity and times of the presystolic wave mesured in LVOT, size and diastolic function of the left ventricular. Result: The prevalence of left ventricular (LV) presystolic wave on doppler echocardiography of patients with diabetes mellitus 2 (DM2) is found to be 90%, which is lower than that of the control group (93%) (p>0,05). The wave velocity in DM2 patients is 64.7 ± 15.5 cm/s, which is higher than that in the control group (56.2 ± 11.3 cm/s) (p<0.05), and the velocity in DM2 patients with LV diastolic dysfunction is higher than in those with normal LV diastolic function.  (74,3 ± 11,3 and 58,5 ± 11,2 respectively, p<0,001). The wave duration in DM2 patients is 97.5 ± 15.4ms, which is longer than that in the control group (92.9 ± 17.00 cm/s)(p>0,05). No noticeable difference in wave duration was observed between DM2 patients with LV diastolic dysfunction and those with normal LV diastolic function.
