Angiographic characteristics of coronary disease and postresuscitation electrocardiograms in patients with aborted cardiac arrest outside a hospital.
ABSTRACT Postresuscitation electrocardiogram (ECG) in patients with aborted cardiac death may demonstrate ST-elevation myocardial infarction (STEMI), ST-T changes, intraventricular conduction delay, or other nonspecific findings. In the present study, we compared ECG to urgent coronary angiogram in 158 consecutive patients with STEMI and 54 patients not fulfilling criteria for STEMI admitted to our hospital from January 1, 2003 through December 31, 2008. At least 1 obstructive lesion was present in 97% of patients with STEMI and in 59% of patients without STEMI with ≥1 occlusion in 82% and 39%, respectively (p <0.001). Obstructive lesion was considered acute in 89% of patients with STEMI and in 24% of patients without STEMI (p <0.001). An acute lesion in STEMI had a higher thrombus score (2.6 vs 1.3, p = 0.05) and more often presented with Thrombolysis In Myocardial Infarction grade 0 to 1 flow (75% vs 36%, p <0.01). Percutaneous coronary intervention, which was attempted in 148 lesions in patients with STEMI and in 17 lesions in patients without STEMI, resulted in final Thrombolysis In Myocardial Infarction grade 3 flow in 87% and 71%, respectively (p = 0.34). In conclusion, STEMI on postresuscitation ECG is usually associated with the presence of an acute culprit lesion. However, in the absence of STEMI, an acute culprit lesion is still present in 1/4 of patients. An acute lesion in STEMI is more thrombotic and more often leads to complete occlusion. Urgent percutaneous coronary intervention is feasible and successful regardless of postresuscitation ECG.

ABSTRACT: Outcomes in patients with out-of-hospital cardiac arrest (CA) who undergo percutaneous coronary intervention (PCI) have been limited to small, mostly single-center studies. We compared patients who underwent PCI after CA included in the CathPCI Registry with those without CA. Patients with ST elevation were classified as ST-elevation myocardial infarction (STEMI); all other patients having PCI were classified as without STEMI. Patients with CA in each group were compared with the corresponding non-CA groups for baseline characteristics, angiographic findings, and outcomes. A total of 594,734 patients underwent PCI, of whom 114,768 had STEMI, including 9,375 (8.2%) had CA, and 479,966 had without STEMI, including 2,775 (0.6%) had CA. Patients with CA were similar in age to patients with non-CA, with a lower frequency of coronary disease risk factors and known coronary disease. On angiography, patients with CA were significantly more likely to have more complex lesions with worse baseline thrombolysis in myocardial infarction flow. Patients with CA were significantly more likely to have cardiogenic shock, both for patients with STEMI (51% vs 7.2%, respectively) and for patients without STEMI (38% vs 0.8%, respectively, both p <0.001). In-hospital mortality was substantially worse in patients with CA, for both patients with STEMI (24.9% vs 3.1%, respectively) and patients without STEMI (18.7% vs 0.4%, respectively). In conclusion, patients who underwent PCI after CA had more complex anatomy, more shock, and higher mortality. The substantially increased mortality in patients with CA has important implications for the development and regionalization of centers for CA.The American journal of cardiology 01/2014; · 3.58 Impact Factor

ABSTRACT: Approximately 400,000 Europeans are yearly resuscitated from out-of-hospital cardiac arrest (OHCA).(1,2) Despite evolving evidence based guidelines for cardiopulmonary resuscitation (CPR), survival rates after OHCA has not improved much in several places around the world. However, a potential for improved survival is absolutely present, based on the huge spread in worldwide survival; some cities with survival over 20-30% and some cities with just a few percent.(1,2) These survival differences can partly be explained by different definitions of OHCA,(2) but mainly due to the overall quality of the local Chain of Survival (COS)(3); early arrest recognition and call for help, early CPR, early defibrillation and early post resuscitation care. By identifying and thereafter improving weak links in the local COS, survival can indeed increase. This review will focus on the quality of the last link in the COS, the hospital treatment after return of spontaneuous circulation (ROSC), and how good quality post resuscitation care can improve not only survival, but survival with neurologically intact outcome.Best practice & research.
