• Abstract Aim Cardiovascular disease is the main cause of death in diabetic patients undergoing haemodialysis. Dialysis and hypertension increase left ventricular hypertrophy (LVH), a strong predictor of cardiovascular events. This study evaluated left ventricular structure and function in three groups of hypertensive type 2 diabetic patients with different renal function, and assessed the factors associated with LVH, in an Afro-Caribbean population. Methods Left ventricular structure and function were measured by ultrasonography. Group 1 consisted of 150 patients with normal renal function, group 2 included 183 patients with renal dysfunction and the third group comprised 75 dialysis patients. Results Left ventricular mass/height2.7 increased from group 1 to groups 2 and 3 (49.00 g/m2.7 , 57.12 g/m2.7 and 59.75 g/m2.7 , respectively; P < 0.0001). The prevalences of LVH were 48.3% in group 1, 64.8% in group 2 and 70.3% in the dialysis patients ( P = 0.001). LVH was more concentric than eccentric in groups 2 and 3. The factors significantly associated with LVH were obesity in groups 1 and 2, and an increase of 10 mmHg in pulse pressure in groups 2 and 3, according to multivariate logistic-regression analysis. Conclusion Our study confirmed that, in a population of Afro-Caribbean hypertensive type 2 diabetic patients, renal failure was associated to an increased left ventricular mass/height2.7 . The data show that the variables associated with LVH differ according to renal profile. This finding will be of value in the treatment and follow-up of these patients.
