First statin monotherapy to achieve regression of coronary atherosclerosis by angiography in a major clinical study

03-Apr-2008

According to AstraZeneca, CRESTOR(R) (rosuvastatin) is the only statin to show regression of coronary atherosclerosis in a major clinical study. That result, which was based on intravascular ultrasound (IVUS) data from the ASTEROID study, has now been expanded upon by quantitative coronary angiography (QCA) measurements obtained during that study. This is the first time that QCA was used to demonstrate regression of atherosclerosis as a result of statin monotherapy. These new data were presented today at the 57th Annual Scientific Session of the American College of cardiology and showed that rosuvastatin treatment for 24 months reduced LDL-C levels well below traditional goals (1.57 mmol/L), together with significant increases in HDL-C, produced regression by decreasing percent diameter stenosis and improving minimum lumen diameter as measured by QCA in coronary disease patients.

"The QCA analysis of the ASTEROID study offers us additional, consistent insights into the treatment of patients with coronary artery disease," said Dr. Jean-Claude Tardif, Director of the Montreal Heart Institute Research Centre, and member of the ASTEROID steering committee. "Both QCA and IVUS techniques confirm that the use of rosuvastatin 40 mg can help achieve regression of coronary atherosclerosis, the underlying cause of heart disease."

ASTEROID (A Study To Evaluate the Effect of Rosuvastatin On Intravascular Ultrasound-Derived Coronary Atheroma Burden) was designed to study the effect of rosuvastatin 40 mg in 507 patients who had undergone coronary angiography and who had evidence of coronary artery disease (CAD). The QCA analysis was a secondary endpoint in the ASTEROID study. Angiograms taken at baseline and at the end of the 2 year study were analysed for changes in the percent diameter stenosis (%DS) and the minimum lumen diameter (MLD) using QCA imaging.
