Cardiovascular Disease Clinical Trial
Official title:
Effect of Homocysteine-Lowering Therapy With Folic Acid, Vitamin B12, and Vitamin B6 on Endothelium-Dependent Vasodilatation of Forearm Resistance Vessels in Patients With Coronary Heart Disease
Endothelial dysfunction is an early marker of atherosclerosis and is found in patients (pts) with coronary (CAD) and peripheral artery disease (PAD). Statin-therapy has been shown to improve endothelial function in pts with CAD or PAD by reducing LDL-cholesterol and inflammatory markers. B-group vitamin-supplements have variable been reported to have positive or neutral effects on endothelial function. Therefore, we want to compare the effect of rosuvastatin and B-group vitamin supplementation on endothelial function of the forearm resistance vessels in pts with cardiovascular disease.
Study design: 36 pts with CAD or PAD are randomly assigned to either rosuvastatin 10mg/d or vitamin supplementation with folic acid 1mg, vitamin B12 0.4mg and B6 10mg/d for 6 weeks in a double-blinded design. After 6 weeks all pts receive rosuvastatin and vitamin supplementation in combination for additional 6 weeks. ;
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
