Determinants of coronary artery disease risk factor management across three world regions

BACKGROUND: The SUrvey of Risk Factors (SURF) indicated poor control of risk factors in subjects with established coronary heart disease (CHD). The present study aimed to investigate determinants of risk factor management in patients with CHD. METHODS AND RESULTS: SURF recruited 9987 consecutive patients with CHD from Europe, Asia and the Middle East between 2012 and 2013. Risk factor management was summarised as a Cardiovascular Health Index Score (CHIS) based on six risk factor targets (non-smoker/ex-smoker, body mass index <30, adequate exercise, controlled blood pressure, controlled low-density lipoprotein and controlled glucose). Logistic regression models assessed the associations between determinants (age, sex, family history, cardiac rehabilitation, previous hospital admission and diabetes) and achievement of moderate CHIS (≥3 risk factors controlled). The results are presented as OR with corresponding 95% CI. A moderate CHIS was less likely to be reached by women (OR 0.90, 95% CI 0.69 to 1.00), those aged <55 years old (OR 0.62, 95% CI 0.53 to 0.76) and those with diabetes (OR 0.41, 95% CI 0.37 to 0.46). Attendance in cardiac rehabilitation was associated with better CHIS achievements (OR 1.62, 95% CI 1.42 to 1.87). Younger Asian and European patients had poorer risk factor management, whereas for patients from the Middle East age was not significantly associated with risk factor management. The availability and applicability of cardiac rehabilitation varied by region. CONCLUSIONS: Overall, risk factor management was poorer in women, those younger than 55 years old, those with diabetes and those who did not participate in a cardiac rehabilitation. Determinants of cardiovascular risk factor management differed by region.
