Resumo The aim of our prospective study was to evaluate the influence of blood glucose (BG) on left ventricular mass and diastolic function in patients with hypertension and type 2 diabetes mellitus (DM). Fifty-six hypertensive patients with type 2 DM and 26 healthy controls were investigated. They were submitted to echocardiography (ECHO) with Doppler and we calculated the mean of their fasting BG values, office blood pressure (OBP), cholesterol and fractions, and triglycerides during the previous 4 years. the diabetic patients were then followed-up for 1 year with OBP, fasting BG, and lipids measured every 2 months. After this period, the patients were again submitted to ECHO and in 22 patients (group I [GI]), reductions greater than 10% in left ventricular mass index (LVMI) were observed (122 +/- 35 nu 89 +/- 23 g/m(2), P < .01), whereas increases greater than 10% (group II [GII], n = 17) (94 +/- 18 <nu> 115 +/- 27 g/m(2), P < .01) or no changes (group III [GIII], n = 17) (98 +/- 16 <nu> 99 +/- 18 g/m2, NS) in LVMI were detected in the remaining patients. the OBP values did not change during the follow-up. in GI the reduction of LVMI was associated with a BG fall from 178 +/- 36 to 147 +/- 30 mg/dL (P < .01) and a correlation was observed between BG and LVMI percent variations (<Delta>) (r = 0.48, P < .01). No important changes in left ventricular diastolic function were observed during the follow-up. We concluded that the improvement in glycemic control may contribute to LVH regression in hypertensive patients with type 2 DM.
