Effects of Atorvastatin 10 mg Versus 40 mg in Eight Months Follow-up Coronary Flow Reserve and Bone Marrow Stem Cell Mobilization in Patients With Acute Myocardial Infarction

Summary

Many data indicate that statins increase mobilization of bone marrow-derived stem cells, and circulating bone marrow-derived stem cells are capable of homing to sites of myocardial infarction and endothelial disruption, thereby restoring myocardial function and microvascular integrity after acute myocardial infarction. Atorvastatin is widely used in the treatment of hyperlipidemia, especially after acute myocardial infarction. High-dose atorvastatin has been known to stop the progression of atherosclerosis and to decrease the levels of inflammatory markers. The purpose of this prospective, randomized, single-blinded trial is to compare the effect of atorvastatin 10 mg versus 40 mg in restoring coronary flow reserve (CFR) and in serial bone marrow stem cell mobilization during the 8 months follow-up in patients with acute myocardial infarction.
