Background: Left Ventricular hypertrophy is a complication of type 2 diabetes. Severe Left Ventricular hypertrophy increases the rate of heart failure in Types 2 Diabetes. Purpose: To study Left Ventricular dysfunction in type 2 Diabetes patients with Left Ventricular hypertrophy. Subjects and methods: Cross-sectional Research enrolled 63 type 2 diabetes patients who underwent examination and treatment at Hospital No.108 (Central Military Hospital No.108) from October 2009 to October 2010. Subjects included 23 women and 40 men, with the average age at 64.3 + or - 7.1, ages ranged from 52 to 70. Subjects were divided into two groups: 33 type 2 diabetes patients who had Left Ventricular hypertrophy and 30 type 2 diabetes patients who did not have Left Ventricular hypertrophy. Comparisons in left ventricular chambers' size, systolic and diastolic functions between the two subject groups were made using Doppler echocardiography. Other statistical data were recorded using SPSS 15.0
Results: - Group of type 2 Diabetes patients who had left ventricular hypertrophy had larger left atrium and left ventricle than the group of type 2 Diabetes patients who did not. (p 0.01 and p 0.001), this group had three patients (9.9 percent) with ejection fraction EF 40 percent. - Left Ventricular hypertrophy in Type 2 diabetes group resulted in increasing A wave velocity (VA), reducing E velocity (VE), reducing VENA, prolonging DT and IVRT. The risk of Diastolic Heart Failure in diabetic group with Left Ventricular hypertrophy decreased significantly compared with the diabetic group without Left Ventricular hypertrophy (78.3 percent compared with 43.3 percent, p 0.05).
