Aim Of The Study: We studied the clinical profile, management, and outcomes of patients with out-of-hospital cardiac arrest (OHCA) with and without ST-elevation myocardial infarction (STEMI).
Methods: Retrospective analysis of the 20-year registry data (January 1991- June 2010) was conducted on patients with cardiac disease hospitalized at Hamad General Hospital and Qatar Heart Hospital, Doha, Qatar.
Results: A total of 987 patients with OHCA were admitted to the cardiology department during the study period; among them, 296 (30%) patients had STEMI. Compared to the patients with OHCA without STEMI, the patients who had OHCA with STEMI were younger (53 ± 13 vs 58 ± 16 years; P = .001), more likely to be male (78% vs 34%; P = .001), smokers (35% vs 14%) but less likely to have hypertension (30% vs 48%; P = .001), diabetes (32% vs 47%, P = .001), and chronic renal failure (3.4% vs 9%; P = .002). The use of thrombolytic treatment in patients with STEMI increased from 21.6% (period 1991-1095) to 44.4% (period 2006-2010); P = .04.
Conclusion: Percutaneous coronary intervention had increased significantly during the last quarter of the study. There was a decline in the in-hospital mortality among patients with STEMI during the last quarter of the study.

: Fever in patients who have suffered an out-of-hospital cardiac arrest (OHCA) has been linked to poor clinical outcomes, as a fever can exacerbate neurological damage, increase metabolic demands, and trigger inflammatory responses. This study evaluates the impact of the COVID-19 outbreak and associated fevers on OHCA outcomes and examines how they can worsen patient prognosis. : Our retrospective observational analysis used data from the National Emergency Department Information System (NEDIS), comprising adult OHCA patients at 402 EDs in Korea between 27 January and 31 December 2020 (COVID-19 pandemic period) and the corresponding period in 2019 (pre-COVID-19).

: Sudden cardiac arrest (SCA) is a severe medical condition involving the cessation of the heart's mechanical activity. Following the chain of survival, which includes early recognition and calling for help, early initiation of cardiopulmonary resuscitation (CPR), early defibrillation, and post-resuscitation care, offers the greatest chances of saving a person who has experienced SCA. The aim of this study was to analyze cases of out-of-hospital cardiac arrest (OHCA) and assess the actions taken by bystanders.

This study uses machine learning and multicenter registry data for analyzing the determinants of a favorable neurological outcome in patients with out-of-hospital cardiac arrest (OHCA) and developing decision support systems for various subgroups. The data came from the Korean Cardiac Arrest Research Consortium registry, with 2679 patients who underwent OHCA aged 18 or above with the return of spontaneous circulation (ROSC). The dependent variable was a favorable neurological outcome (Cerebral Performance Category score 1-2), and 68 independent variables were included, e.

Background: Targeted temperature management (TTM) is considered a beneficial treatment for improving outcomes in patients with OHCA due to acute coronary syndrome (ACS). The comparative benefits of hypothermic TTM (32-34°C) versus normothermic TTM (35-36°C) are unclear. This study compares these TTM strategies in improving neurological outcomes and survival rates in OHCA patients with ACS.

Background And Aims: Guidelines suggest non-traumatic out-of-hospital cardiac arrest (OHCA) be conveyed to cardiac arrest centres (CAC). We hypothesised that (a) a pre-hospital conveyance algorithm based on initial presenting rhythm following OHCA is feasible and (b) that would demonstrate survival advantage.
Methods: This observational pilot study included all consecutive patients with OHCA from suspected cardiac aetiology from the county of Essex, United Kingdom from April 2022-April 2023.
