Rationale and design of the St. Francis Heart Study: a randomized clinical trial of atorvastatin plus antioxidants in asymptomatic persons with elevated coronary calcification.
Early detection of asymptomatic subjects who are at risk for future cardiovascular events may allow for earlier medical treatment in order to prevent disease progression and future events. Electron-beam computed tomography accurately identifies people with increased coronary calcification, which is correlated with increased coronary plaque mass, increased likelihood of obstructive coronary disease, and increased likelihood of future cardiovascular events. The St. Francis Heart Study is a single-center combination study of men and women 50-70 years old that includes a natural history study of the relation between calcium scores and cardiovascular events (n = 5582), the association of calcium scores with traditional and nontraditional coronary disease risk factors (n = 1160), and a randomized clinical trial designed to assess the benefit of combination treatment with atorvastatin, vitamin C, and vitamin E, as compared to placebos, in subjects with elevated age- and gender-adjusted coronary calcification (n = 1007). Mean follow-up duration will be 4 years. The study is proceeding on schedule with anticipated completion by August 2002. It should provide important information regarding the benefits of treating asymptomatic men and women who have elevated coronary artery calcium, using cholesterol reduction and antioxidant therapy. The article describes the design of the St. Francis Heart Study.
