Association between stress hyperglycemia ratio and mortality in patients with heart failure complicated by sepsis.
Sci Rep
December 2024

Individuals afflicted with heart failure complicated by sepsis often experience a surge in blood glucose levels, a phenomenon known as stress hyperglycemia. However, the correlation between this condition and overall mortality remains unclear. 869 individuals with heart failure complicated by sepsis were identified from the Medical Information Mart for Intensive Care-IV (MIMIC-IV) database and categorized into five cohorts based on their stress hyperglycemia ratio (SHR).

Department of Cardiology, West China Hospital of Sichuan University, 37 Guoxue Alley, Wuhou District, Chengdu, 610041, Sichuan, China.
Intracardiac echocardiography (ICE) has been used to guide radio-frequency catheter ablation (RFCA) for better catheter navigation and less radiation exposure in treating atrial fibrillation (AF). This retrospective cohort study enrolled 227 AF patients undergoing ICE- or traditional fluoroscopy (TF)-guided RFCA for AF in a tertiary hospital. ICE was used more often in patients with atrial tachycardia [odds ratio (OR) 3.

Hypertrophic cardiomyopathy (HCM) afflicts humans, cats, pigs, and rhesus macaques. Disease sequelae include congestive heart failure, thromboembolism, and sudden cardiac death (SCD). Sarcomeric mutations explain some human and cat cases, however, the molecular basis in rhesus macaques remains unknown.

Pulmonary arterial hypertension (PAH) is a serious medical condition that causes a failure in the right heart. Two-pore channel 2 (TPC2) is upregulated in PAH, but its roles in PAH remain largely unknown. Our investigation aims at the mechanisms by which TPC2 regulates PAH development.

Heart transplantation remains the ultimate treatment strategy for neonates and children with medically refractory end-stage heart failure and utilization of donors after circulatory death (DCD) can expand th donor pool. We have previously shown that mitochondrial transplantation preserves myocardial function and viability in neonatal swine DCD hearts to levels similar to that observed in donation after brain death (DBD). Herein, we sought to investigate the transcriptomic and proteomic pathways implicated in these phenotypic changes using ex situ perfused swine hearts.
