Abstract
With so many statins available for clinical use in coronary artery syndromes, there has been much discussion about which is the best. Two recent trials have compared the clinical outcomes of intensive lipid lowering with atorvastatin 80 mg/day and standard lowering with pravastatin 40 mg/day. In the Pravastatin or Atorvastatin Evaluation and Infection Therapy (PROVE IT) trial, patients with acute coronary artery syndromes were enrolled, and pravastatin lowered the low-density lipoprotein (LDL)-cholesterol to 2.46 mmol/l, whereas atorvastatin lowered it to 1.60 mmol/l. Associated with this, there was a lower rate of clinical events (myocardial infarction, revascularisation) over 2 years with atorvastatin than pravastatin (22.4 versus 26.3%, respectively). The Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) trial also enrolled patients requiring angiography, and pravastatin lowered the LDL-cholesterol to 2.84 mmol/l, whereas atorvastatin lowered the LDL-cholesterol to 2.04 mmol/l. In the REVERSAL trial, atheroma volume progressed with pravastatin by 2.7% whilst remaining stable in the atorvastatin group (-0.4%) over 18 months. Thus, atorvastatin 80 mg/day causes a greater reduction in LDL-cholesterol than pr...Continue Reading
