Abstract
- OBJECTIVE: To examine levels of NT-proBNP and its relation to hypertension, as well as diastolic function in normoalbuminuric patients with Type 2 diabetes. RESEARCH DESIGN AND METHODS: The study comprised 60 Type 2 diabetic patients without albuminuria. Thirty patients were normotensive and 30 had hypertension. Exclusion criteria were cardiac symptoms and an ejection fraction < 55%. Thirty age- and sex-matched normal subjects served as controls. Diastolic dysfunction was assessed with echocardiography, by means of mitral inflow and colour M-Mode flow propagation recordings. RESULTS: Overall NT-proBNP was significantly elevated in the Type 2 diabetes group, compared with the controls [54.5 pg/ml (5-162) vs. 32.7 pg/ml (5-74.3) P = 0.02]. NT-proBNP was significantly higher among hypertensive patients compared with both normotensive patients and controls but no difference was found between the normotensive patients and the controls [58.0 pg/ml (8.5-162), P < 0.05 vs. 50.8 pg/ml (5-131) P = 0.4]. Patients with concentric and eccentric hypertrophy had significantly higher NT-proBNP levels compared with the control group [81.0 pg/ml (5-147), P < 0.001 and 66.8 pg/ml (42-128), P < 0.001], whereas patients with left ventricular remodelling (enlarged relative wall diameter but normal left ventricular mass) were comparable with the control group [42.3 pg/ml (8.3-142) P = 0.55]. Patients with left atrial enlargement also had incremental NT-proBNP values. NT-proBNP was only moderately correlated to age (r = 0.33, P < 0.05) and left ventricular diastolic diameter (r = 0.41, P < 0.05), but unrelated to diastolic function. CONCLUSIONS: NT-proBNP is significantly increased in hypertensive, normoalbuminuric patients with Type 2 diabetes. These findings were related to left ventricular hypertrophy and increased left atrial and ventricular diameters. [ABSTRACT FROM AUTHOR]
