Comparison of left ventricular function by tissue Doppler imaging in patients with diabetes mellitus without systemic hypertension versus diabetes mellitus with systemic hypertension.
Because diabetes mellitus substantially increases the risk of development of heart failure, we sought to establish early alterations in left ventricular systolic and diastolic function in patients with diabetes mellitus with and without coexisting systemic hypertension. We studied 134 subjects using echocardiography comprising standard 2-dimensional and conventional Doppler as well as tissue Doppler imaging. Our study demonstrated the early appearance of both left ventricular systolic and diastolic dysfunction in diabetic patients at rest and the contributory effects of diabetes to myocardial impairment produced by hypertension, as well as the high usefulness of tissue Doppler imaging in detection and quantitation of myocardial dysfunction in diabetics. This method was superior to other echocardiographic techniques and plasma brain natriuretic peptide evaluation.
