OBJECTIVES To examine the relationship between blood urea nitrogen (BUN)-to-creatinine ratio and the prognosis of chronic heart failure (HF). METHODS We analyzed the data from the cohort of 243 adult patients with chronic HF followed at the HF clinic in a tertiary medical center between December 2003 and June 2006. Primary endpoints were the events of(More)
PURPOSE (18)F-Fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT has the potential to track vascular inflammation and monitor therapeutic response. The purpose of this study was to determine the association between arterial inflammation, calcification and serological biomarkers in subjects with atherosclerosis, and to assess their therapeutic(More)
OBJECTIVE To assess the effects of different classes of antihypertensive treatments, including monotherapy and combination therapy, on survival and major renal outcomes in patients with diabetes. DESIGN Systematic review and bayesian network meta-analysis of randomised clinical trials. DATA SOURCES Electronic literature search of PubMed, Medline,(More)
BACKGROUND Chronic kidney disease is a health burden for the general population. We designed a cohort study to construct prediction models for chronic kidney disease in the Chinese population. METHODS A total of 5168 participants were followed up during a median of 2.2 (interquartile range, 1.5-2.9) years, and 190 individuals (3.7%) developed chronic(More)
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is independently associated with QT prolongation among patients with diabetes. It has not yet been determined whether this association remains valid in the general population. We designed an observational study to explore this association. METHODS AND RESULTS We conducted a cross-sectional analysis of 31(More)
OBJECTIVES Many criteria of metabolic syndrome have been made available to practitioners in the recent past. This study has been designed to investigate the distribution, agreement and classification patterns of these criteria among the ethnic Chinese population. METHODS A total of 6610 (women, 42.5%) adults (mean, 52.3 years) were recruited from the(More)
The role of post-prandial glucose on cardiovascular risk among Chinese adults without diabetes was investigated. In a median follow-up of 3.5 years on 16,590 participants, 95 cardiovascular deaths were found. The relative risk in the highest quintile post-prandial glucose was 1.61 (P for trend, 0.05) for cardiovascular death.
BACKGROUND Evidence of predictive power of various fatty acids on the risk of metabolic syndrome was scanty. We evaluated the role of various fatty acids, including saturated fat, monounsaturated fat, transfat, n-6 fatty acid, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), for the risk of the metabolic syndrome in Taiwan. RESULTS A nested(More)
BACKGROUND Evidence about whether white blood cell (WBC) or its subtypes can act as a biomarker to predict the ischemic stroke events in the general population is scanty, particularly in Asian populations. The aim of this study is to establish the predictive ability of total WBC count or subtypes for long-term ischemic stroke events in the cohort population(More)
