Zinc supplementation in patients with acute myocardial infarction.

This single-centre prospective feasibility study (UMIN000030232) evaluated whether zinc supplementation was safe and effective for improving outcomes among patients with acute myocardial infarction (AMI). Within 24 h after successful primary percutaneous coronary intervention, consenting patients with AMI were randomly assigned 1:1 to receive conventional treatment (conventional treatment group) or conventional treatment plus zinc acetate supplementation (zinc supplementation group). The two groups were compared in terms of major adverse cardiovascular events (MACE), and scar size, which was evaluated using cardiac magnetic resonance imaging (CMR) at 4 weeks after discharge.

Relationship between early drop in systolic blood pressure, worsening renal function, and in-hospital mortality in patients with heart failure: a retrospective, observational study.

This study aimed to determine the optimal cut-off value of the early drop in systolic blood pressure (SBP) for worsening renal function (WRF) in hospitalized patients with heart failure (HF) and analyze predictors of WRF and the early drop in SBP at that threshold. We retrospectively enrolled 396 patients with acute decompensated HF. The early drop in SBP was defined as the difference between baseline and SBP measured 24 h after hospitalization.

Grid-mapping catheters versus PentaRay catheters for left atrial mapping on ensite precision mapping system.

Introduction: Areas displaying reduced bipolar voltage are defined as low-voltage areas (LVAs). Moreover, left atrial (LA) LVAs after pulmonary vein isolation (PVI) have been reported as a predictor of recurrent atrial fibrillation (AF). In this study, we compared grid mapping catheter (GMC) with PentaRay catheter (PC) for LA voltage mapping on Ensite Precision mapping system.

Poor prognosis of heart failure patients with in-hospital worsening renal function and elevated BNP at discharge.

Aims: Our purpose was to investigate the association between the B-type natriuretic peptide (BNP) level at discharge, the occurrence of worsening renal function (WRF), and long-term outcomes in patients with heart failure (HF).

Methods And Results: We enrolled hospitalized acute HF patients. We divided patients into four groups on the basis of BNP <250 pg/mL (BNP-) or BNP ≥250 pg/mL (BNP+) at discharge and the occurrence of WRF during admission: BNP-/WRF-, BNP-/WRF+, BNP+/WRF-, and BNP+/WRF+.

The impact of worsening renal function with elevated B-type natriuretic peptide at discharge on 1-year prognosis in heart failure patients.

There are a few studies about the clinical impacts of plasma B-type natriuretic peptide (BNP) at discharge with the occurrence of worsening renal function (WRF) on mortality in patients with heart failure (HF). We divided total 301 patients with acute decompensated HF into four groups by the median value (278.7 pg/mL) of BNP level at discharge and by the occurrence of WRF.
