Effect of Atorvastatin on E.C.G Changes in Coronary Artery Disease

E.C.G is the most widely used test for both the diagnosing and estimating the prognosis of CAD. ST segment and T wave changes are most commonly evaluated parameters of E.C.G. Atorvastatin have found to decrease ischemic events apart from its hypolipidemic effect. The main objective of this open prospective randomized, controlled study was to evaluate the effect of addition of atorvastatin to conventional antianginal treatment on ST segment and T wave changes on E.C.G. The study was conducted for duration of 2 months in 30 patients of CAD (15 in each group). Group A was started on conventional antianginal treatment and group B was started on Atorvastatin 20 mg once a day at night in addition to conventional treatment. The ECG changes were recorded after 15, 30, 45 and 60 days using 12 lead E.C.G. At the end of the study, no significant difference was found in E.C.G changes between the group A and group B. A slight improvement in ST segment changes in group B patients was observed but the effect was statistically not significant. So, addition of atorvastatin to conventional antianginal treatment did not have a significant effect on reversal of ischemic changes on ECG in patients of CAD.
