Therapeutic implications of recent ATP III guidelines and the important role of combination therapy in total dyslipidemia management.
The Adult Treatment Panel III report reemphasized the importance of reducing elevated levels of low-density lipoprotein cholesterol as the most efficacious treatment target to reducing coronary heart disease morbidity and mortality, which is the leading cause of disability and death in the United States. Although the etiologic role of elevated levels of low-density lipoprotein cholesterol in atherosclerosis is well established, treatment with statins still leaves a large proportion of patients vulnerable to cardiovascular events. The role of high-density lipoprotein cholesterol in atherosclerosis is increasingly recognized because of its strong inverse association with coronary heart disease in epidemiologic studies, and the observed high prevalence of low high-density lipoprotein cholesterol that occurs in populations with coronary heart disease, with or without elevated low-density lipoprotein cholesterol, especially among patients with diabetes and metabolic syndrome. This report highlights some of the therapeutic implications of the Adult Treatment Panel III report and various therapeutic approaches to both lowering elevated low-density lipoprotein cholesterol and triglycerides as well as increasing low levels of high-density lipoprotein cholesterol to optimize clinical event rate reduction in patients with coronary heart disease. Among available dyslipidemic therapies, although statins remain the mainstay for lowering low-density lipoprotein cholesterol and clinical events, niacin is currently the most effective agent for increasing low high-density lipoprotein cholesterol levels. The importance of combination dyslipidemic therapy, such as a statin plus niacin, in treating more optimally the entire lipid profile has been demonstrated not only to decrease progression and increase regression of atherosclerotic lesions, but to enhance event-free survival compared with statin monotherapy. Combination dyslipidemic therapy affords the most efficacious approach to controlling the multiple lipid abnormalities associated with atherosclerotic cardiovascular disease and optimizing cardiovascular event rate reduction in patients with coronary heart disease.[1]References
