Evaluation of left ventricular diastolic function in patients with diabetes mellitus by tissue doppler imaging:Report of 30 cases

Objective To evaluate of left ventricular diastolic function in patients with diabetes mellitus by tissue doppler imaging.Methods Thirty patients with diabetic and 26 healthy subjects were studied in this study.Early diastolic velocity and late diastolic velocity were measured on six sites of mitral annulus by tissue doppler imaging.The mean peak Ouvelocity(mVe、mVa) and ratio(mVe/mVa) were calculated.Results Compared with healthy subjects,there was a significant difference in those parameters of mVe,mVa and mVe/mVa(P0.01).Conclusion Tissue doppler imaging can quantify diastolic velocity on mitral annulus and detect abnormal left ventricular diastolic function in early.It provides early evidence for diabetic cardiomyopathy.
