We hypothesized an interaction effect and conducted stratified analyses to investigate whether witnessed arrest is more important than bystander CPR.MethodsThis study enrolled patients with outofhospital cardiac arrest between January 2010 and December 2022 in 3 emergency medical service (systems in Taiwan).

A patient had a cardiac arrest with ventricular fibrillation and was successfully defibrillated. IF the initial ECG following successful defibrillation shows evidence of acute OMI — such patients have much to gain from immediate cath with PCI. What percent of shockable arrests without STE have an OMI? 5% vs. 58%!!

Circulation, Volume 150, Issue Suppl_1 , Page A4142952-A4142952, November 12, 2024. In the subgroup with Class 3 of recommendation for implantable cardioverter defibrillator, patients with absolute LV-GLS ≤ 9% showed significantly worse prognosis than those with absolute LV-GLS > 9% (p =.002 vs -266.2; vs -264.9;

Both the Comparison of Medical Therapy, Pacing and Defibrillation in Heart Failure (COMPANION) and the Cardiac Resynchronisation—Heart Failure (CARE-HF) trials [3,4], which were the cornerstone of electrotherapy in HF patients, showed up to a 36% reduction in mortality, an effect size rarely seen in trials today [5].

She was never seen to be in ventricular fibrillation and was never defibrillated. We studied this and published the abstract below in 2010. The combination of sudden increased intracranial pressure with loss of spontaneous circulation results in near total loss of cerebral perfusion. Circulation 122:Abstract 101.
