Left ventricular diastolic function was estimated as the ratio of early diastolic velocity (E) from transmitral inflow to early diastolic velocity (e\u2019) of tissue Doppler at mitral annulus (E\/e\u2019). Parameters of glycemic control, plasma insulin concentration, treatment with antidiabetic drugs, lipid profile, and other clinical characteristics were evaluated, and their association with E\/e\u2019 determined. Patients with New York Heart Association class &gt;1, ejection fraction &lt;50%, history of coronary artery disease, severe valvulopathy, chronic atrial fibrillation, or creatinine clearance &lt;30\u2005mL\/min, as well as those receiving insulin treatment, were excluded.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Univariate analysis showed that E\/e\u2019 was significantly correlated with age (p&lt;0.001), sex (p&lt;0.001), duration of diabetes (p=0.002), systolic blood pressure (p=0.017), pulse pressure (p=0.010), fasting insulin concentration (p=0.025), and sulfonylurea use (p&lt;0.001).
