Contribution of a risk factor clinic to lipid management in patients with coronary artery disease

The progress of a cohort of 145 patients seen between June 1986 and June 1989 was reviewed. These patients had treatment prescribed by the clinic and had data recorded over serial visits; they allowed us to determine the contribution of the risk factor clinic. Eighty-six percent had coronary artery disease. Patients were given nutritional advice, partly in groups. In addition 61% were treated with drug therapy. Seventy-four percent had modified their diet before the clinic visit but only 32% received less than 30% of energy from fat; the number rose to 67% by discharge. Sixty-four percent had a body mass index of 25 or greater, falling to 53% at discharge. Mean total cholesterol of the 145 patients was 7.9, HDL cholesterol 1.06, and total:HDL cholesterol ratio 7.7 mmol/L. Changes with clinic management were: total cholesterol -19%, HDL cholesterol +11%, total:HDL cholesterol ratio -25%, LDL cholesterol -21%. Despite these changes, levels were less than optimal for patients with coronary arterial disease in at least 50% of patients at the time of discharge. Improved results can be achieved only with a more aggressive approach to drug therapy. Recent studies in patients with coronary disease provide strong support for such a change in management.
