Effects of adherence to guidelines for the control of major cardiovascular risk factors on outcomes in the REduction of Atherothrombosis for Continued Health (REACH) Registry Europe

Abstract

Objectives To examine the impact of cardiovascular risk factor control on 3-year cardiovascular event rates in patients with stable symptomatic atherothrombotic disease in Europe. Methods The REduction of Atherothrombosis for Continued Health (REACH) Registry recruited patients aged ≥45 years with established atherothrombotic disease or three or more risk factors, of whom 20 588 symptomatic patients from 18 European countries were analysed in this study at baseline and 12, 24 and 36 months. ‘Good control’ of cardiovascular risk factors was defined as three to five risk factors at target values of international guideline recommendations (systolic blood pressure Results Among symptomatic patients in the REACH Registry Europe (mean age 67 years, 70.6% male), 59.4% had good control of risk factors at baseline. Good risk factor control was associated with lower cardiovascular death/non-fatal stroke/non-fatal myocardial infarction (OR 0.76; 95% CI 0.69 to 0.83) and mortality (OR 0.89; 95% CI 0.79 to 0.99) at 36 months, compared with poor control. Independent predictors of good control of risk factors included residence in western versus eastern Europe (OR 1.29), high level of education (OR 1.16), established coronary artery disease (OR 1.18), treatment with one or more antithrombotic (OR 1.59) and one or more lipid-lowering agent (OR 1.16). Conclusions In REACH, less than 60% of patients with stable atherothrombotic disease had good control of the five major cardiovascular risk factors. Improved risk factor control is associated with a positive impact on 3-year cardiovascular event rates and mortality.
