AimsWe aimed to perform a systematic review and meta-analysis to assess the association between serum uric acid and incident heart failure (HF)/prognosis of HF patients. Methods and resultsA systematic electronic literature search was conducted in Embase (Ovid SP, from 1974 to May 2013), Medline (Ovid SP, from 1946 to May 2013), and the Chinese Biomedical Literature Database (CBM, from 1978 to May 2013) to identify studies reporting on the association between serum uric acid and HF. Either a random effects model or a fixed effects model was used for pooling data. Five studies reporting on incident HF and 28 studies reporting on the adverse outcomes of HF patients were included. The results showed that hyperuricaemia was associated with an increased risk of incident HF [hazard ratio (HR) 1.65, 95% confidence interval (CI) 1.41-1.94], and the risk of all-cause mortality (HR 2.15, 95% CI 1.64 -2.83), cardiovascular mortality (HR 1.45, 95% CI 1.18 -1.78), and the composite of death or cardiac events (HR 1.39, 95% CI 1.18-1.63) in HF patients. For every 1 mg/dL increase in serum uric acid, the odds of development of HF increased by 19% (HR 1.19, 95% CI 1.17-1.21), and the risk of all-cause mortality and the composite endpoint in HF patients increased by 4% (HR 1.04, 95% CI 1.02-1.06) and 28% (HR 1.28, 95% CI 0.97-1.70), respectively. Subgroup analyses supported the positive association between serum uric acid and HF. ConclusionsElevated serum uric acid is associated with an increased risk of incident HF and adverse outcomes in HF patients.--

Plasma GDF-15 is an independent predictor of all-cause mortality in Chinese patients with HF. It may potentially be used to stratify and prognosticate HF patients.

Systolic and diastolic dysfunction existed in systemic amyloidosis with preserved EF. Mechanical contraction disorder may be one reason for systolic dysfunction. GPLSR and GPRSR were negatively related to IVS thickness.

Objective We performed a prospective observational study to explore the prognostic value of plasma galectin-3, a biomarker for fibrosis and inflammation, in Chinese patients with heart failure (HF). Methods and results Galectin-3, N-terminal pro B-type natriuretic peptide (NT-proBNP) and other clinically related variables were measured in consecutive HF patients in Beijing Hospital. Specifically, galectin-3 was detected by an enzyme-linked immunosorbent assay. The primary end point was major adverse cardiac events (MACE), including all-cause mortality or readmission at the end of follow-up. The secondary end point was all-cause mortality. The adjusted hazard ratio (HR) was determined by COX regression model. In total, 272 patients were included in this study with a median age of 77 years, of whom 55.9% were male. During a median follow-up of 584 (415-813) days, 53 patients (19.5%) died and 103 patients (37.9%) died and/or required readmission. Plasma galectin-3 levels by tertiles were associated with an increased risk for the primary end point (P < 0.001). Kaplan-Meier survival curves showed that the third tertile of galectin-3 was associated with an increased rate of MACE, compared with the first and second tertiles, with the log rank P < 0.001 and P = 0.001, respectively. In addition, the multivariate COX regression model showed that the highest tertile of galectin-3 was associated with an increased risk for MACE (HR =2.13, 95% confidence interval: 1.24-3.68, P = 0.006), compared with the lowest tertile after adjustment for age, NT-proBNP, creatinine, uric acid, albumin, haemoglobin, and estimated glomerular filtration rate (eGFR). Conclusion Plasma galectin-3 is an independent predictor of all-cause mortality and/or readmission in Chinese patients with HF.
