Differentiating between comatose patients resuscitated from acute coronary syndrome-associated and subarachnoid hemorrhage-associated out-of-hospital cardiac arrest

Abstract

Initial ED evaluation is sufficient to differentiate between comatose ACS-OHCA and SAH-OHCA patients prior to further diagnostic work-up (e.g. emergent coronary angiography and head computed tomography).

The use of prehospital variables to predict acute coronary artery disease in failed resuscitation attempts for out-of-hospital cardiac arrest

“…Gender differences in etiology of cardiac arrest and likelihood of survival, as well as age at presentation of first myocardial infarction have been described previously, [24][25][26][27] all of which may help explain the differential effect of age on the likelihood of underlying CAD observed between genders in our study. Women were not highly represented in our database, however, constituting only 26% of cases.…”

Clinical Factors Associated with Obstructive Coronary Artery Disease in Patients with Out-of-Hospital Cardiac Arrest: Data from the Korean Cardiac Arrest Research Consortium (KoCARC) Registry

“…They also stated that old age and initial shockable rhythm were associated with CAD, which is consistent with ours. Also, previous studies of patients who had intracranial hemorrhage as a cause of OHCA found that the prevalence of shockable rhythm was significantly lower compared to those who did not 1738. Although regarding the role of shockable rhythm as a positive prognostic factor is not fully understood in MI patients, a short time to administration of medical assistance and a relatively lower burden of myocardial ischemia may contribute to better outcome in those with shockable rhythm 39.…”

Resistance to conventional cardiopulmonary resuscitation in witnessed out-of-hospital cardiac arrest patients with shockable initial cardiac rhythm

“…Nevertheless, the reported incidences of AMI are 36-61% [8,[15][16][17][18][19], which is similar to our finding. In this study, we diagnosed AMI exclusively based on CAG findings, because clinical and ECG findings are poor predictors of AMI in OHCA [15][16][17][18][19][20], and troponin levels can be elevated in patients with OHCA (even those without AMI) [21]. Interestingly, epidemiologic data indicate that DCM and HCM are the second most common causes of sudden cardiac death (10-15%), and other cardiac disorders (e.g.…”
