Impact of three-month treatment with pitavastatin on arterial stiffness in patients with hypercholesterolemia: a prospective observational study

Abstract

Objective: Although several studies have highlighted the benefits of statins in improving arterial stiffness, there is limited research on whether pitavastatin, a more recently developed statin, has similar effects. This study aimed to investigate the impact of pitavastatin on arterial stiffness in patients with hypercholesterolemia.

Methods: This prospective study enrolled 115 patients with hypercholesterolemia (mean age, 59 years; 22% female) who had not previously been treated with statins. Participants underwent lifestyle interventions followed by administration of pitavastatin (2 or 4 mg daily) if target low-density lipoprotein (LDL) cholesterol levels were not achieved. The primary outcome measured was the change in brachial-ankle pulse wave velocity (baPWV) from baseline after three months of treatment.

Results: Pitavastatin treatment significantly reduced LDL cholesterol by 41.1% (from 158 ± 28 to 93.0 ± 29.6 mg/dL; P < 0.001). Additionally, systolic blood pressure (SBP) decreased significantly from 130 ± 14 to 126 ± 14 mmHg (P < 0.001), representing a 2.9% reduction, and baPWV decreased significantly from 1522 ± 325 to 1407 ± 289 cm/s (P < 0.001), a 7.6% reduction. There was a significant correlation between changes in SBP and changes in baPWV (r = 0.565; P < 0.001). Even after adjusting for changes in SBP, the reduction in baPWV induced by pitavastatin remained statistically significant (P < 0.001).

Conclusion: A three-month treatment with pitavastatin effectively reduced arterial stiffness in patients with hypercholesterolemia, alongside significant improvements in lipid profiles and blood pressure reductions. These findings support the use of pitavastatin for managing key cardiovascular risk factors.
