Coronary angiographic and culprit lesion characteristics in patients resuscitated from out-of-hospital cardiac arrest

Abstract Funding Acknowledgements Type of funding sources: None. Background Emergent coronary angiography is recommended in patients with return spontaneous circulation (ROSC) after out hospital cardiac arrest (OHCA) suspected origin. The aim this study was to analyze the prevalence artery disease (CAD), characteristics culprit lesions case acute syndrome (ACS) and success percutaneous intervention (PCI) resuscitated from OHCA due a shockable rhythm, i.e. ventricular fibrillation (VF) tachycardia (VT). Methods We analyzed data 150 whom performed setting ROSC OHCA. Patients were categorized have non obstructive CAD or CAD. classified as myocardial infarction (ST-elevation (STEMI), Non-ST-elevation (NSTEMI)) chronic syndrome. vessel identified by means electrocardiographic findings, echocardiography angiography. Coronary angiograms all clinical reviewed consensus two experienced interventional cardiologists. Successful PCI defined angiographic restoration TIMI III flow. Results Significant ruled 27 (18.0%). Obstructive at least one stenosis found 123 (82.0%). According ACS 105/150 (70.0%). Of 105 ACS, 53 (35.3%) presented STEMI 52 (34.7%) NSTEMI. 18/123 (14.6%) showed Among CAD, 1-vessel 32 (26.0%), 2-vessel 44 (35.8%), 3-vessel 47 (38.2%). 41 (33.3%) total occlusion (CTO) vessel. In presenting most common vessels LAD (37.4%) CX (23.6%), followed RCA (11.4%) LM (2.4%). 22.8% patients, could not be unambiguously identified. 82.9% ACS/CAD, performed. flow 92.1%, II 3.9%, I 2.0% 0 2.0%. Conclusion VF/VT, multivessel common. Most frequently, are located CX. can high rate.
