P6210Pathway of care and life course of patients with recurrent ST-elevation myocardial infarction

Abstract

Abstract Background We hypothesized that patients having experienced one coronary event in their life must present differences in their pathway of care in the acute phase and within 12-month life course. Purpose This study aimed to compare pathways between current and recurrent Myocardial Infarction. Methods All patients from the OSCAR registry with ST Elevation Myocardial Infarction (STEMI) as final diagnosis from 2013 to 2016 were included. We defined recurrent STEMI as a reinfarction occurring within 12-month post-current-STEMI and STEMI with prior MI occurred before the inclusion date. Results Recurrent STEMI called more often the medical dispatch center (71.32% vs 62.36%, p<0.0001) and benefited from out-of-hospital medical care by Emergency Mobile Services (67.07% vs 59.70%, p=0.0007). The hospital management delays did not differ but the delay symptom-ECG tended to be 26 minutes longer for recurrent STEMI admitted directly to the emergency department (182 [109; 314] vs 156 [89; 291], p=0.0510). They also underwent less percutaneous coronary interventions (PCI) (90,24% vs 95,07%, p<0.0001). At 12 months post-discharge, we observed a better adherence to BASIC-treatment (Beta-blockers, Anti-platelet medications [aspirin, clopidogrel, prasugrel], Statins and Converting Enzyme Inhibitor Combination-treatment) for recurrent STEMI (64,06% vs 52,98%, p=0.0062) but the key lifestyle interventions were less applied. Conclusion Comparison of care and life course of current and recurrent STEMI highlighted a different use of pre-hospital care and hospital resources. They also showed better adherence to BASIC-treatment during recurrent events compared to current STEMI.
