Review Meta AnalysisThe effect of green tea on blood pressure and lipid profile: a systematic review and meta-analysis of randomized clinical trials.
Many different dietary supplements are currently marketed for the management of hypertension, but the evidence for effectiveness is mixed. The aim of this systematic review was to evaluate the evidence for or against the effectiveness of green tea (Camellia sinensis) on blood pressure and lipid parameters. ⋯ Green tea intake results in significant reductions in systolic blood pressure, total cholesterol, and LDL cholesterol. The effect size on systolic blood pressure is small, but the effects on total and LDL cholesterol appear moderate. Longer-term independent clinical trials evaluating the effects of green tea are warranted.

Randomized Controlled TrialEffects of six months of vitamin D supplementation in patients with heart failure: a randomized double-blind controlled trial.
Low plasma vitamin D levels have been associated with heart failure (HF). This research attempts to explain the role of vitamin D supplementation on myocardial function in elderly patients with HF. ⋯ Six months of vitamin D supplementation significantly improves EF in elderly patients with HF and vitamin D deficiency.

Prediction of cardiovascular disease by abdominal obesity measures is dependent on body weight and sex--results from two community based cohort studies.
To study waist-hip ratio (WHR), waist circumference (WC), sagittal abdominal diameter (SAD), and waist-hip-height ratio (WHHR) as predictors of CVD, in men and women stratified by BMI (cut-off ≥25). ⋯ In normal weight individuals, WHHR and WHR were the best predictors in women, whereas SAD was the only independent predictor in men. Among overweight/obese individuals all measures failed to predict CVD in women, whereas WHHR was the strongest predictor after adjustments for CVD risk factors in men.
