Combination therapy of candesartan with statin inhibits progression of atherosclerosis more than statin alone in patients with coronary artery disease
Coronary Artery Disease, 08/19/2011Suzuki T et al.
Combination therapy of renin–angiotensin system (RAS) inhibitor with statin is more effective than statin alone in inhibiting atherosclerotic progression of coronary arteries and the aorta in patients with coronary artery disease.
Using 64 multislice computed tomography,
Vessel wall areas (VWAs) and total vascular areas of the left main trunk (LMT) and proximal right coronary artery (RCA) and the thoracic descending aorta (TDA) were determined in patients with coronary artery disease before and after 2.0–year treatment with atorvastatin and candesartan (n=20) or with atorvastatin alone (n=16).
Although these patients had been treated with the combination therapy or statin alone at the study enrollment.
Plasma levels of high sensitive C–reactive protein, matrix metalloproteinase–9, and urinary 8–iso–prostaglandin F2 α were determined at the baseline.
There were no significant differences in low–density lipoprotein and high–density lipoprotein cholesterol, C–reactive protein, matrix metalloproteinase–9, or urinary 8–iso–prostaglandin F2 α levels between the two groups.
Two years later, total vascular areas of TDA and RCA increased significantly in the atorvastatin group but not in the combination group.
Moreover, increases in VWAs were less in the combination group than in the atorvastatin group in TDA (3.6±23.1 vs. 28.6±25.5 mm2, P=0.004), RCA (?1.6±1.6 vs. 0.6±2.5 mm2, P=0.005), and left main trunk (?0.9±3.5 vs. 1.3±2.4 mm2, P=0.095).
Biomarker levels at the baseline did not affect the progression of VWA.
