The phosphodiesterase inhibitor cilostazol induces regression of carotid atherosclerosis in subjects with type2 diabetes mellitus.
Background: Antiplatelet drugs are effective in preventing recurrence of atherosclerosis in type 2 diabetic patients.However, the efficacy and usefulness of 2 different antiplatelet drugs, aspirin and cilostazol, in the progression of carotidintima-media thickening are unknown.
Methods and Results: To compare prevention by cilostazol and aspirin of progression of atherosclerosis, we conducteda prospective, randomized, open, blinded end point study in 4 East Asian countries. A total of 329 type 2 diabetic patients suspected of peripheral artery disease were allocated to either an aspirin-treated (81 to 100 mg/d) group or acilostazol-treated (100 to 200 mg/d) group. The changes in intima-media thickness of the common carotid artery duringa 2-year observation period were examined as the primary end point.
The regression in maximum left, maximum right, mean left, and mean right common carotid artery intima-media thickness was significantly greater with cilostazol compared with aspirin (_0.088_0.260 versus 0.059_0.275 mm, P_0.001; _0.042_0.274 versus 0.045_0.216 mm, P_0.003; _0.043_0.182 versus 0.028_0.202 mm, P_0.004; and _0.024_0.182 versus 0.048_0.169 mm, P_0.001). In a regression analysis adjusted for possible confounding factors such as lipid levels and hemoglobin A1c, theimprovements in common carotid artery intima-media thickness with cilostazol treatment over aspirin treatment remained significant.
Conclusions: Compared with aspirin, cilostazol potently inhibited progression of carotid intima-media thickness, an established surrogate marker of cardiovascular events, in patients with type 2 diabetes mellitus.
