Rosuvastatin Affecting Aortic Valve Endothelium

Background: Recent retrospective studies support the hypothesis that statins slow the progression of aortic stenosis. The aim of this study was to assess the effect of Rosuvastatin on hemodynamic progression of aortic stenosis by treating patients with aortic stenosis and elevated LDL-cholesterol for 18 months.

Methods: We performed an open-label, prospective study evaluating 121 consecutive patients with asymptomatic moderate to severe aortic stenosis (AVA≥ 1.0 cm2), (mean age 73.7±8.9 years; 57 men and 64 women), treated with and without Rosuvastatin according to the NCEP-ATPIII guidelines. Echocardiographic, serum lipid, and inflammatory markers were measured at baseline and every 6 months for 18 months.

Inclusion criteria

• Asymptomatic AS
• Normal ejection fraction
• Elevated LDL >130 mg/dl

Exclusion criteria

• Echocardiographic evidence of rheumatic mitral valve disease,
• Previous statin therapy,
• Congenital heart disease (bicuspid aortic valve),
• Subaortic obstruction,
• Creatinine ≥ 2,0 mg/dl (to avoid the potential confounder of an elevated serum [CaP04]),
• Evidence of liver disease,
• Greater than mild aortic regurgitation and previous aortic valve surgery
