Ventricular arrhythmias (VA) are a major cause of morbidity and mortality in patients with coronary artery disease (CAD). Current guidelines recommend revascularization of significant CAD to improve survival in patients with ventricular fibrillation (VF), polymorphic ventricular tachycardia (VT), or those who are post-cardiac arrest. However, revascularization is not recommended for CAD patients with suspected scar-mediated monomorphic VT. There is a paucity of data detailing the utility of revascularization in reducing VA in CAD patients who do not present with acute coronary syndrome (ACS) and are not immediately post-cardiac arrest, which is the focus of this review. Medline, Scopus, and the Cochrane Central Register of Controlled Trials were systematically searched to identify relevant studies addressing this question. Studies that included patients presenting with ACS or those who were immediately post-cardiac arrest at the time of revascularization were excluded. In total, five studies comprising 2663 patients were reviewed.

Background: Current Pediatric Advanced Life Support Guidelines recommend maintaining blood pressure (BP) above the 5th percentile for age following return of spontaneous circulation (ROSC) after cardiac arrest (CA). Emerging evidence suggests that targeting higher thresholds, such as the 10th or 25th percentiles, may improve neurologic outcomes. We aimed to evaluate the association between post-ROSC BP thresholds and neurologic outcome, hypothesizing that maintaining mean arterial pressure (MAP) and systolic blood pressure (SBP) above these thresholds would be associated with improved outcomes at hospital discharge.

Background: The Blood Pressure and Oxygenation Targets After out-of-hospital cardiac arrest (BOX) trial found no statistically significant differences in mortality or neurological outcomes with mean arterial blood pressure targets of 63 versus 77 mmHg in patients receiving intensive care post-cardiac arrest. In this study, we aimed to evaluate the effect on 1-year mortality and assess heterogeneity in treatment effects (HTE) using Bayesian statistics.
Methods: We analyzed 1-year all-cause mortality, 1-year neurological outcomes, and plasma neuron-specific enolase (NSE) at 48 hours using Bayesian logistic and linear regressions primarily with weakly informative priors.

Purpose: We studied the promising Alzheimer biomarker plasma tau phosphorylated at threonine 231 (p-tau231) in a cohort of cardiac arrest patients who survived to intensive care to predict long-term neurological outcomes. We also compared it to total tau (t-tau), which has demonstrated predictive abilities of neurological outcome post-cardiac arrest.
Methods: This observational multicentre cohort study included 425 patients admitted to intensive care after cardiac arrest.
