Association of Arterial Wave Properties and Diastolic Dysfunction in Patients With Type 2 Diabetes Mellitus

Abstract

Left ventricular (LV) diastolic dysfunction and increased arterial stiffness are prevalent in patients with type 2 diabetes mellitus (DM). Because the systemic vasculature plays a pivotal role in myocardial loading, this study aimed to determine the effect of arterial characteristics on LV diastolic function in patients with type 2 DM. Conventional echocardiography and tissue Doppler imaging were performed in 155 patients with type 2 DM (88 men; mean age 55 ± 11 years) with preserved LV ejection fractions (>50%). Patients were stratified into groups on the basis of LV diastolic function (normal, n = 53; delayed relaxation, n = 79; pseudonormal, n = 23). Arterial wave reflection parameters an..
