Risk factor management in diabetic and non-diabetic patients with coronary heart disease. Findings from the EUROASPIRE I AND II surveys.

Aims/hypothesis: We examined risk factor management in diabetic and non-diabetic patients with CHD based on data from EUROASPIRE surveys.

Methods: Consecutive CHD patients aged 70 years or younger were interviewed and examined at least 6 months after hospitalisation for a revascularisation procedure or acute myocardial infarction or ischaemia. Of these patients, 3569 were from the EUROASPIRE I study, undertaken from 1995 to 1996 in nine countries, and 5556 were from the EUROASPIRE II study, conducted between 1999 and 2000 in 15 countries.

Results: In EUROASPIRE I and II 18% and 20% of CHD patients respectively had been previously diagnosed with diabetes. Fasting glucose screening raised the prevalence of diabetes in EUROASPIRE II to 28%. In EUROSPIRE II the prevalence of risk factors (known diabetic/non-diabetic) was: current smoking 17%/22 % ( p=0.25); obesity (BMI >/=30 kg/m(2)) 43%/29% ( p<0.001); raised blood pressure (>/=140/90 mm Hg) 57%/49% ( p<0.001); and elevated total cholesterol (>/=5.0 mmol/l) 55%/59% ( p<0.001). The proportion of users of cardiovascular medication was: antiplatelet drugs 83%/86% (NS); beta-blockers 62%/63% (NS); ACE inhibitors 49%/35% ( p<0.001); and lipid-lowering drugs 62%/61% (NS). A comparison of both studies showed that for diabetic and non-diabetic patients the prevalence of smoking had increased somewhat and that the prevalence of obesity had increased clearly. There was no improvement in blood pressure control, but cholesterol control had improved, mainly explained by the increased use of lipid-lowering drugs.

Conclusions/interpretation: These European surveys show a high prevalence of adverse lifestyles and modifiable risk factors among diabetic and non-diabetic patients with CHD. The risk factor status was more adverse in diabetic patients.
