Gender differences in secondary prevention of coronary heart disease: reasons to worry or not?

Abstract

Scand J Prim Health Care 2003;21:37-42. ISSN 0281-3432 Objective - To analyse potential gender differences in cardiovascular risk factors and treatment patterns, reflecting clinical practice in secondary prevention. Design - Observational national study during 3 years of patients eligible for secondary prevention of coronary heart disease (CHD). Setting - Fifty-two healthcare districts in Sweden, involving primary health care and hospitals in collaboration, participating in a national quality assurance programme for the prevention of CHD. Subjects - A national sample of male and female patients surviving acute myocardial infarction, or following CABG/PTCA interventions for CHD, controlled at 3-6 months (n=9135) and 12 months (n=4802) of follow-up. The proportion of female patients (25%) did not differ between visits. Main outcome measures - Self-reported data on lifestyle, drug treatment and cardiovascular risk factor levels after consultation in general practice or at hospital policlinics. Results - No major gender differences were recorded in risk factor levels or in cardiovascular drug treatment patterns at 12 months of follow-up. Female patients participated in educational programmes to improve lifestyle to a higher degree than males (52.0 vs 45.1%), but after 1 year were more often (p<0.001) self-reported smokers (11.7 vs 8.4%). Female patients showed higher levels of blood pressure, total cholesterol and HDL cholesterol, but not LDL cholesterol compared to male patients. Conclusions - In general, a gender-equal level of lipid control and access to medical drug treatment has been established for patients in secondary prevention from a national sample in Sweden, followed for 1 year after CHD manifestations and related interventions.
