Frequency of left ventricle diastolic dysfunction in asymptomatic type II diabetic patients

Aim: to find the frequency of left ventricular diastolic dysfunction in patients with diabetes on doppler echocardiography by measuring their early to late diastolic mitral inflow velocity (e/a ratio) and deceleration time (dt) on pulse wave (pw) doppler and e′ velocity on tissue volume imaging (tvi). methods: a sample of 97 asymptomatic patients,male and female,was taken from department of cardiology in punjab institute of cardiology and gulab devi hospital,lahore from august 2015 to october 2015 by direct personal navigation method to collect data through performa. results: out of 97 patients,54(55.7%) patients presented with grade i diastolic dysfunction,6(6.2%) patients presented with grade ii diastolic dysfunction and 11(11.3%) patients presented with grade iii diastolic dysfunction. patients with grade i diastolic dysfunction had mean e/a ratio of 0.81,deceleration time (dt) 209.4 ms (p ≤ 0.05) and e′ velocity 5.74 m/s (p ≤ 0.05). patients with grade ii diastolic dysfunction had mean e/a ratio of 1.08,deceleration time 128.8 ms and e′ velocity 4.9 m/s while patients with grade iii diastolic dysfunction had mean e/a ratio of 1.54,deceleration time 155 ms and e′ velocity 4.9 m/s. conclusion: it is concluded that diastolic dysfunction is significantly associated with diabetes mellitus. echocardiography is valuable for diagnosis of left ventricular diastolic dysfunction. it should be routinely advice in every patient with diabetes along with other parameters for control of diabetes. © 2016,lahore medical and dental college. all rights reserved.
