Cardiovascular disease (CVD) is one of the leading causes of death in the United States. CVD is attributed to a combination of major risk factors including hypertension, dyslipidemia, obesity, poor diet, low physical activity levels, and vascular endothelial cell dysfunction. The vascular

Search strategy: A literature search of the Cochrane Library, Medline and PubMed will be conducted with the following search terms: "dietary supplements or supplement*" AND "cardiovascular disease or myocardial infarction or stroke or cardiovascular death or mortality or all-cause mortality or

Two large, nutritional intervention trials were conducted in Linxian, China between 1985-1991. These trials tested the effect of multiple vitamins and minerals in the prevention of esophageal cancer in a population with the highest known rate for this disease in the world. Results from the trials

OBJECTIVES: Primary - To determine whether vitamin E every other day reduces the risk of developing prostate cancer in older healthy male physicians. - To determine whether daily vitamin C and/or a multivitamin reduces the risk of total cancer in these participants. - To determine whether vitamin E

DESIGN NARRATIVE: The aspirin component of the trial was terminated on January 25, 1988, due to a demonstrated benefit of aspirin on myocardial infarction. At that time, however, the number of strokes and CV deaths experienced by trial participants was inadequate to definitively evaluate these

BACKGROUND: The PHS is a cohort which included 14,916 men initially free of cardiovascular disease and cancer who provided plasma samples at study entry in 1982. These men were randomly assigned in a factorial design to aspirin or beta-carotene therapy, and have been followed prospectively for the

BACKGROUND: Both in vivo and in vitro experiments have show that flavonoids, antioxidants which are rich in green tea, are potentially as beneficial as vitamin E, beta-carotene and vitamin C in reducing the risk of cardiovascular disease. Thus, the possible preventive effects of green tea on CHD

The Women's Antioxidant and Folic Acid Cardiovascular Study tested the effects of vitamin C (500 mg/day), vitamin E (600 IU every other day), and/or beta carotene (50 mg every other day) on the risk of major cardiovascular events (a combined outcome of myocardial infarction, stroke, coronary

BACKGROUND: More than one-third of patients with coronary disease have "low" high density lipoprotein cholesterol (HDLc) levels (less than 35 mg/dl; United States 20th percentile) and "normal" low density lipoprotein cholesterol (LDLc) (less than 145; United States mean), a group for whom current

BACKGROUND: Multiple mechanisms are involved in the deposition of LDL-C into the arterial wall, and the prevention of such deposition as well as the removal of the LDL-particles. Further, there remain questions regarding what causes an existing plaque that has been stable for a long period of time
