The benefit of aggressive lipid lowering.
The beneficial effects of lipid-lowering therapy for the primary and secondary prevention of coronary heart disease (CHD) have been conclusively demonstrated in large-scale clinical trials. Does more aggressive lipid lowering provide even greater clinical benefit? The post coronary artery bypass graft (post-CABG) study was the first angiographic trial to show that aggressive lipid-lowering therapy was more effective at reducing disease progression than conventional approaches to cholesterol management. Recently, the results of the atorvastatin versus revascularization treatments (AVERT) trial have also shown significant benefit on clinical events with aggressive lipid lowering. A total of 341 patients with stable CHD were randomly assigned to receive medical therapy with atorvastatin 80 mg/day plus conventional treatment or angioplasty followed by usual care. Atorvastatin therapy resulted in a 46% reduction in the mean low-density lipoprotein cholesterol level compared with an 18% decrease for patients in the angioplasty/usual care group. Patients treated with atorvastatin had fewer ischemic events compared with those who had angioplasty (13 vs. 21%, P = 0.048) and a significantly greater time to first ischemic event (P = 0.027). AVERT is the first clinical study demonstrating that patients with stable CHD achieve significant cardiovascular benefit by aggressively lowering cholesterol levels with atorvastatin. It would therefore appear that an aggressive approach to lipid-lowering therapy is beneficial in patients with existing CHD.
