BACKGROUND The effect of green tea catechins (GTCs) with or without caffeine on glycemic control is controversial. OBJECTIVE We aimed to identify and quantify the effects of GTCs or GTC-caffeine mixtures on glucose metabolism in adults. DESIGN A comprehensive literature search was conducted to identify relevant trials of GTCs with or without caffeine on(More)
BACKGROUND The effect of green tea beverage and green tea extract on lipid changes is controversial. OBJECTIVE We aimed to identify and quantify the effect of green tea and its extract on total cholesterol (TC), LDL cholesterol, and HDL cholesterol. DESIGN We performed a comprehensive literature search to identify relevant trials of green tea beverages(More)
The effect of tea intake on blood pressure (BP) is controversial. We performed a meta-analysis of randomised controlled trials to determine the changes in systolic and diastolic BP due to the intake of black and green tea. A systematic search was conducted in MEDLINE, EMBASE and the Cochrane Controlled Trials Register up to May 2014. The weighted mean(More)
No therapy has been shown to improve survival rate in heart failure with preserved ejection fraction (HFPEF). Recent observational studies of the association between statin use and the risk of mortality in HFPEF have shown mixed results. The goal of the present study was to systematically review all published observational studies evaluating the effect of(More)
BACKGROUND The effects of lipophilic statins in heart failure (HF) were controversial. The goal of the present study was to systematically review all randomised controlled trials evaluating the effects of lipophilic statins in patients with HF. METHODS We performed a comprehensive literature search to identify eligible trials that prospectively randomised(More)
Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. The goal of the present study was to quantify the association between use of nonsteroidal anti-inflammatory drugs (NSAIDs) and risk of AF incidence. MEDLINE and EMBASE were searched for studies that reported risk of AF associated with nonaspirin NSAID use. Combined relative risk(More)
BACKGROUND The role of plasma high sensitivity C-reactive protein (hs-CRP) in in-stent restenosis (ISR) remains controversial. We investigated plasma hs-CRP level at both admission and follow-up in patients with stable angina (SA) after successful coronary stenting in order to clarify the predictive value of hs-CRP for ISR. METHODS We summarized 303(More)
Myocardial bridging is a common congenital abnormality of a coronary artery, and is usually thought to be a benign anatomical variant. Although rare, previous studies have reported that patients with myocardial bridging may suffer from myocardial ischemia, myocardial infarction (MI), arrhythmias and even sudden death. Here we report the case of an(More)
BACKGROUND Spontaneous attack of variant angina (VA) is a unique component of coronary artery disease (CAD), and associated with severe cardiac events. However, no data are available regarding sex differences in Chinese patients with spontaneous attacks of VA. Accordingly, the present retrospective study was initiated to evaluate the Clinical(More)
BACKGROUND Although the role of C-reactive protein (CRP) in predicting rapid progression of atherosclerotic lesions has been intensively studied in unstable coronary artery disease, the data from patients with stable angina (SA) are largely absent. The present study evaluated a middle-size patient cohort who underwent percutaneous coronary intervention(More)
