Review Meta Analysis
Effect of omega-3 fatty acids supplementation on endothelial function: a meta-analysis of randomized controlled trials.
Inverse association was reported between omega-3 fatty acids (FAs) supplementation and the risk of cardiovascular disease. Identifying the effect of omega-3 FAs on endothelial function may contribute to explain the association. We conducted a meta-analysis to assess the effect of omega-3 FAs supplementation on endothelial function, as measured by flow-mediated dilation (FMD) and endothelium-independent vasodilation (EIV). ⋯ Supplementation of omega-3 fatty acids significantly improves the endothelial function without affecting endothelium-independent dilation.

Randomized Controlled Trial
Effect of Omega-3 fatty acid supplementation on markers of platelet and endothelial function in patients with peripheral arterial disease.
Omega-3 fatty acids have been shown to reduce platelet and endothelial activation in patients with or at risk of cardiac disease. We aimed to determine if Omega-3 fatty acid supplementation in addition to best medical therapy can reduce the increased platelet and endothelial activity that is present in patients with intermittent claudication. ⋯ Supplementation with Omega-3 fatty acids had no affect on platelet and endothelial activation or markers of inflammation in patients with peripheral arterial disease.

Multicenter Study
Associations of dietary magnesium intake with mortality from cardiovascular disease: the JACC study.
The authors sought to investigate the relationship between dietary magnesium intake and mortality from cardiovascular disease in a population-based sample of Asian adults. Reported findings are based on dietary magnesium intake in 58,615 healthy Japanese aged 40-79 years, in the Japan Collaborative Cohort (JACC) Study. Dietary magnesium intake was assessed by a validated food frequency questionnaire administered between 1988 and 1990. ⋯ The multivariable hazard ratio (95% CI) for the highest vs. the lowest quintiles of magnesium intake after adjustment for cardiovascular risk factor and sodium intake was 0.49 (0.26-0.95), P for trend = 0.074 for hemorrhagic stroke in men, 0.68 (0.48-0.96), P for trend = 0.010 for total stroke, 0.47 (0.29-0.77), P for trend < 0.001 for ischemic stroke, 0.50 (0.30-0.84), P for trend = 0.005 for coronary heart disease, 0.50 (0.28-0.87), P for trend = 0.002 for heart failure and 0.64 (0.51-0.80), P for trend < 0.001 for total cardiovascular disease in women. The adjustment for calcium and potassium intakes attenuated these associations. In conclusion, dietary magnesium intake was associated with reduced mortality from cardiovascular disease in Japanese, especially for women.

Carotid intima-media thickness (CIMT), a marker of early atherosclerosis and vascular remodelling, is one of the independent predictors of coronary artery disease (CAD). However, it is unknown whether ultrasonic assessment of carotid atherosclerosis, including CIMT, improves the prediction ability for CAD over and above conventional coronary risk factors in the diabetic patients. ⋯ In type 2 diabetic patients without apparent cardiovascular disease, the addition of max-IMT to conventional risk factors substantially improves the risk stratification for CAD.
