Background: It has been reported that pitavastatin improves endothelial function faster than other statins. Recently introduced reactive hyperemia peripheral arterial tonometry (RH-PAT) provides objective and quantitative assessment of peripheral microvascular function.
Purpose: This study aimed to investigate whether peripheral microvascular function improved 2 hours after pitavastatin in subjects with coronary artery disease (CAD) using RH-PAT, and the results were compared with those of rosuvastatin.
Methods: This study included 94 subjects with CAD, assigned to a group given 2 mg of pitavastatin (n = 36), a group given 2.5 mg of rosuvastatin (n = 38), and a control group (n = 20). RH-PAT examinations were performed before and 2 hours after statin administration.
Results: The RH-PAT index increased 2 hours after pitavastatin administration from 1.82 ± 0.45 to 2.16 ± 0.62 (P = 0.02), whereas there were no differences in the RH-PAT index in the rosuvastatin group (1.79 ± 0.71 to 1.91 ± 0.53, P = 0.09) and the control group (1.68 ± 0.36 to 1.84 ± 0.58, P = 0.4). No significant changes were observed at 2 hours in serum cholesterol levels in each group.
Conclusion: The present study demonstrated that peripheral microvascular function improved 2 hours after a single clinical dose of pitavastatin, but not after rosuvastatin.
