These results suggest that reducing DBP to 80 mmHg or less would significantly reduce coronary revascularization and heart failure but at the expense of causing hypotension in CAD patients .
The target of diastolic blood pressure ( DBP ) remains controversial in patients with coronary artery disease ( CAD ) .
Efficacy of perindopril in reduction of cardiovascular events among patients with stable coronary artery disease: randomised, double-blind, placebo-controlled, multicentre trial (the EUROPA study).
BACKGROUND Treatment with angiotensin-converting-enzyme ( ACE ) inhibitors reduces the rate of cardiovascular events among patients with left-ventricular dysfunction and those at high risk of such events . We assessed whether the ACE inhibitor perindopril reduced cardiovascular risk in a low-risk population with stable coronary heart disease and no apparent heart failure . METHODS We recruited patients from October , 1997 , to June , 2000 . 13655 patients were registered with previous myocardial infa rct ion ( 64 % ) , angiographic evidence of coronary artery disease ( 61 % ) , coronary revascularisation ( 55 % ) , or a positive stress test only ( 5 % ) . After a run-in period of 4 weeks , in which all patients received perindopril , 12218 patients were r and omly assigned perindopril 8 mg once daily ( n=6110 ) , or matching placebo ( n=6108 ) . The mean follow-up was 4.2 years , and the primary endpoint was cardiovascular death , myocardial infa rct ion , or cardiac arrest . Analysis was by intention to treat . FINDINGS Mean age of patients was 60 years ( SD 9 ) , 85 % were male , 92 % were taking platelet inhibitors , 62 % beta blockers , and 58 % lipid-lowering therapy . 603 ( 10 % ) placebo and 488 ( 8 % ) perindopril patients experienced the primary endpoint , which yields a 20 % relative risk reduction ( 95 % CI 9 - 29 , p=0.0003 ) with perindopril . These benefits were consistent in all predefined subgroups and secondary endpoints . Perindopril was well tolerated . INTERPRETATION Among patients with stable coronary heart disease without apparent heart failure , perindopril can significantly improve outcome . About 50 patients need to be treated for a period of 4 years to prevent one major cardiovascular event . Treatment with perindopril , on top of other preventive medications , should be considered in all patients with coronary heart disease
