title: Expanding roles for atorvastatin.
abstract: Atherosclerosis, especially when manifested as coronary artery disease (CAD), continues to be the number one cause of mortality and morbidity in developed nations and will soon become so in developing countries. Survivors of an acute heart attack have an increased risk of illness and death that is 1.5-15 times greater than in the general population. Sudden death occurs in myocardial infarction (MI) survivors at a rate 4-6 times greater than in the general population. After an initial recognized MI, 25% of male and 38% of female survivors die within 1 year. Within 6 years after a recognized MI, 18% of men and 35% of women will have a second MI, 7% of men and 6% of women will suffer sudden death, and 22% of men and 46% of women will be disabled with heart failure. Aggressive secondary prevention, therefore, is the key to containing and reversing the "malignant" natural history of CAD, since patients with CAD or CAD risk equivalents are already in the "high risk" category according to the Adult Treatment Panel III (ATP III) of the National Cholesterol Education rogram (NCEP). Treatment of dyslipidemia, especially the reduction of low-density lipoprotein (LDL) cholesterol levels to below 100 mg/dl, was recommended by the 2001 NCEP-ATP Guidelines. In 2004, based on the increasing evidence from several major clinical trials between 2001 and 2004, the NCEP-ATP reaffirmed its LDL goal of < 100 mg/dl in patients with CAD or coronary disease risk equivalents (including multiple risk factors), with an optional LDL goal of < 70 mg/dl in very-high-risk patients (including patients with established coronary heart disease plus other highrisk conditions) Findings from major studies, such as the Treating to New Targets (TNT) study, the Scandinavian Simvastatin Survival Study (4S), the Collaborative Atorvastatin Diabetes Study (CARDS), the Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) trial and, more recently, the Lipid-Lowering Arm of the Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT-LAA), lend support to the idea that greater LDL cholesterol lowering than that achieved with standard doses of statins may be warranted in patients with CAD and metabolic syndrome, CAD and diabetes, CAD and congestive heart failure, and CAD and renal insufficiency. On the other hand, additional lipid reduction may also be warranted in patients with risk factors such as diabetes, hypertension or a history of stroke, but without manifest CAD and despite relatively normal cholesterol levels. These newer indications for statins, atorvastatin in particular, as part of more aggressive secondary and primary prevention, are reviewed in this paper.
