Randomized Controlled Trial Clinical Trial
Cholesterol levels after 3 days of high-dose simvastatin in patients at moderate to high risk for coronary events.
Elevated levels of low-density lipoprotein cholesterol (LDL-C) impair vascular function by a variety of mechanisms. HMG CoA reductase inhibitors (statins) improve endothelial function by lowering LDL-C and possibly by other "pleiotropic" effects. How rapidly statins can lower LDL-C has not been thoroughly studied. ⋯ Treatment with simvastatin for only 3 days results in a 24% drop in the LDL-C level. As defined by ATPIII, this decrease is comparable to that necessary to lower the LDL-C from one risk level to a lower one and is, therefore, both clinically and statistically significant.
