BackgroundStandard modifiable cardiovascular risk factors (SMuRFs) remain well-established elements of assessing cardiovascular risk scores. However, there is growing evidence that patients presented without known SMuRFs at admission demonstrate worse post-myocardial outcomes. The aim of the study was to assess the influence of the SMuRF status on short- and long-term mortality rates in patients with first-time ST-segment elevation myocardial infarction (STEMI).MethodsThis observational, cross-sectional study covered 182,726 patients admitted between 2003-2020 to the CathLabs, according to data from the Polish Registry of Acute Coronary Syndrome. Both baseline characteristics and mortality (in-hospital, 30-day, and 12-month) were examined and stratified by SMuRF status. The predictors of mortality were assessed at selected time points by multivariable analysis.ResultsThe majority of STEMI patients had at least one SMuRF (88.7%), however, mortality rates of SMuRF-less individuals were greater at selected time points of the follow-up (p < 0.001), and persisted at a higher level during each year of the follow-up period compared to the SMuRF group and general population. Furthermore, the SMuRFs status constituted an independent predictor of mortality at the 30-day (OR: 1.345; 95% CI: 1.142-1.585, p < 0.001) and 12-month (OR: 1.174; 95% CI: 1.054-1.308, p < 0.001) follow-ups.ConclusionsSMuRF-less individuals presented with STEMI are at an increased risk of all-cause mortality compared to those with at least one SMuRF. Consequently, further investigations regarding the recognition and treatment of risk factors, irrespective of SMuRF status, are indicated.Copyright © 2024 Southern Society for Clinical Investigation.
