Timing and outcomes after coronary angiography following out of hospital cardiac arrest without sings of ST segment elevation myocardial infarction

Abstract

Less than 10% of individuals who experience out-of-hospital cardiac arrest survive to be discharged from the hospital, making it 1 of leading causes of mortality globally. Less than 40% of individuals with returned of spontaneous circulation who are hospitalised survive. One of the pillars of care for postcardiac arrests is determining & treatment of underlying reason for arrest. this can entail delay in cause-directed treatment if the cause is not always immediately evident. Adults most frequently develop OHCA due to cardiac disease, among which abrupt coronary occlusion is prevalent in aetiology. Early coronary angiography & revascularization are related to increased survival in this cohort because significant fraction of studied cases with ST-segment elevation on initial electrocardiogram after ROSC have acute coronary blockage. Numerous recommendations urge immediate angiography following OHCA with ST elevation following ROSC. incidence of acute coronary occlusion has been significantly lower in individuals without ST elevation after ROSC, & advantages of early angiography have been less certain in these studied cases. percentage of people who experience OHCA without ST elevation is substantially higher & includes people who experience cardiac arrest due to non-cardiac reasons such pulmonary embolism, hypoxia, & drunkenness.
