Association between the Incidence of Sudden Cardiac Arrest and the Location of Culprit Lesions in STEMI Patients – Design of a Prospective Clinical Study

Out-of-hospital cardiac arrest (OHCA) has a poor prognosis and is the most severe complication of any cardiac event. It is known from previous studies that the location of the culprit lesion in ST-segment elevation myocardial infarction (STEMI) patients with cardiac arrest may affect the post resuscitation survival rate. However, due to the low number of cases, the association between the localization of the culprit lesion within the coronary tree and the occurrence of cardiac arrest is not widely discussed, because resuscitated cardiac arrest patients are excluded from the vast majority of clinical trials. This is a prospective observational study that aims to develop a prediction model for OHCA in patients who present with STEMI, based on differences related to culprit lesion location. The primary objective of the study is to evaluate the differences related to the location of the culprit lesion in patients with STEMI who present OHCA versus patients without cardiac arrest.
