Lowering of brachial pulse pressure in 9379 hypertensives with type 2 diabetes and reduction of cardiovascular events.
OBJECTIVE
Pulse pressure (PP) is a major risk factor for cardiovascular (CV) events, mainly in diabetic hypertensives. The objectives of the study were to determine which clinical characteristics could predict the fall in PP and the reduction of CV events under treatment. Design and methods. Type 2 diabetic hypertensives (n = 9379) with PP>60 mmHg (mean age 64 years) were included in a cohort study. During the 9 months follow-up, the physician in charge was asked to reinforce treatment in order to lower PP, using preferentially a fixed low-dose perindopril/indapamide combination.


RESULTS
After 9 months, PP had fallen by 9.1+/-0.2 mmHg (p<0.001). Multivariate analysis of the determinants of PP reduction showed a significant positive association with administration of fixed ACEI/diuretic combination (p<0.001) and a negative association with glycated hemoglobin (p<0.01). During the 9 months follow-up, 632 CV events occurred. In multivariate analysis, the administration of fixed perindopril/indapamide combination was associated with a lower incidence of CV events (OR = 0.64 [0.48-0.86], p<0.01), independently of CV risk factors.


CONCLUSIONS
The reinforcement of therapeutic measures made possible the reduction of PP in type 2 diabetic hypertensives, under conditions of usual care. Administration of a fixed perindopril/indapamide combination therapy was associated with an independent reduction of CV events.
