Background: Little is known about clinical efficacy of newer P2Y12 receptor inhibitors in ST-elevation myocardial infarction patients presenting with cardiogenic shock or after cardiopulmonary resuscitation. The aim of our study was to establish the possible role of newer P2Y12 receptor inhibitors prasugrel and ticagrelor on survival in comparison to clopidogrel administration in ST-elevation myocardial infarction patients presenting with cardiogenic shock and / or after cardiopulmonary resuscitation. Method: The present study was an analysis of 187 patients with ST-elevation myocardial infarction presenting with cardiogenic shock and / or after cardiopulmonary resuscitation. Groups with newer P2Y12 receptor inhibitors (107 patients) and with clopidogrel (80 patients) were compared and followed for median 160 days (25th, 75th percentile: 6,841). Mortality at 14 days, 30 days and one year were compared between the groups. Results: Mortality at 14 days was similar in both groups. A strong trend towards a lower mortality at 30 days was noticed in the newer P2Y12 receptor inhibitors group [39 (48.8%) patients in clopidogrel group died versus 38 (35.5%) in the newer P2Y12 group receptor inhibitors; p = 0.07]. All-cause mortality at one year was significantly higher in the group with clopidogrel administration [47 (58.8%) patients in clopidogrel group died versus 46 (43.0%) in the newer P2Y12 receptor inhibitors group; p = 0.039]. Conclusion: In ST-elevation myocardial infarction patients presenting with cardiogenic shock and/or after cardiopulmonary resuscitation, the administration of newer P2Y12 receptor inhibitors reduced the one-year mortality in comparison to clopidogrel. The use of newer P2Y12 receptor inhibitors may be advocated in this very high risk group of patients.
