Effectiveness of coronary heart disease risk management in high-risk patients.

Abstract

The purpose of this study was to investigate the efficacy of the patient-based coronary heart disease (CHD) risk management strategy in general practice by analyzing patients who were sent to a specialized center as refractory to conventional treatment. Of the 452 patients studied, 152 were excluded because of secondary hyperlipidemia. The effects of a food protocol-monitored dietary/drug treatment on lipid profiles and CHD risk indices and the compliance to this approach were monitored for 12 months in 300 of 452 patients. CHD risk classification was performed according to NIH criteria by the referring physicians, but secondary hyperlipidemia was not identified and treated appropriately. Physicians did not fully utilize dietary and drug treatment and referred the patients to a specialized center too early. The initiated food protocol-controlled treatment was more efficient than pretreatment in general practice, with a compliance of 80.3% by patients selected according to their CHD risk. Long-term CHD risk reduction was persistent for 12 months in compliant patients; however, a cumulative dropout rate of 43% after 6 months and of 68% after 12 months was noted. Statistical analysis failed to reveal consistent prognostic factors of long-term compliance.
