Resumen

Trials suggest patients with ST-elevation myocardial infarction (STEMI) without ‘standard modifiable cardiovascular risk factors’ (SMuRFs) have poorer outcomes, but the role of ethnicity has not been investigated. We analyzed 118,177 STEMI patients using the Myocardial Ischaemia National Audit Project (MINAP) registry. Clinical characteristics and outcomes were analyzed using hierarchical logistic regression models; patients with ≥1 SMuRF (n = 88,055) were compared with ‘SMuRFless’ patients (n = 30,122), with subgroup analysis comparing outcomes of White and Ethnic minority patients. SMuRFless patients had higher incidence of major adverse cardiovascular events (MACE) (odds ratio, OR: 1.09, 95% CI 1.02–1.16) and in-hospital mortality (OR: 1.09, 95% CI 1.01–1.18) after adjusting for demographics, Killip classification, cardiac arrest, and comorbidities. When additionally adjusting for invasive coronary angiography (ICA) and revascularisation (percutaneous coronary intervention (PCI) or coronary artery bypass grafts surgery (CABG)), results for in-hospital mortality were no longer significant (OR 1.05, 95% CI.97–1.13). There were no significant differences in outcomes according to ethnicity. Ethnic minority patients were more likely to undergo revascularisation with ≥1 SMuRF (88 vs 80%, P <.001) or SMuRFless (87 vs 77%, P <.001. Ethnic minority patients were more likely undergo ICA and revascularisation regardless of SMuRF status.
