Secondary prevention of coronary heart disease in primary care: A healthy heart initiative

Abstract

We assessed the effectiveness of secondary prevention of coronary heart disease (CHD) in primary care, in a cross-sectional study of 1015 patients aged < 75 years with documented CHD. Patients records were examined for documentation of CHD risk factors; 722 patients then attended education sessions where blood pressure and cholesterol were measured, a supervised questionnaire detailing modifiable risk factors was completed, and advice on lifestyle modification was given. Management of risk factors was generally poor, and was worse in women. Approximately 20% of subjects remained hypertensive, with half of these receiving antihypertensive medication. Examining the primary care records, serum cholesterol was documented in 17.5% of men and 26.5% of women. Of the 722 subjects who had cholesterol measured, 30% of men and 25% of women had cholesterol < 5.2 mmol/l. Mean cholesterol was significantly higher in the women (6.1 mmol/l vs. 5.6 mmol/l, p = 0.001). Lifestyle risk management was also poor, with significant numbers smoking and drinking more than recommended. Women were more overweight than men (mean BMI 27.9 kg/m2 vs. 26.9 kg/m2, p = 0.006). Aspirin was being taken by 56% of patients.
