Access-Site vs Non-Access-Site Major Bleeding and In-Hospital Outcomes Among STEMI Patients Receiving Primary PCI

BACKGROUND: Major bleeding (MB) is an independent predictor of mortality among ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI).

Sumario:BACKGROUND: Major bleeding (MB) is an independent predictor of mortality among ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). Prevention of access-site MB has received significant attention. However, limited data have been obtained on the influence of access-site MB vs non-access-site MB and association with subsequent adverse in-hospital outcomes in the STEMI population undergoing pPCI. METHODS: We identified 1494 STEMI patients who underwent pPCI between 2012 and 2018. Unadjusted and adjusted differences among patients with no MB, access-site MB, non-access-site MB, and in-hospital clinical outcomes were assessed. The use of bleeding-avoidance strategies and their effects on MB were also evaluated. RESULTS: MB occurred in 121 (8.1%) patients. Access-site MB occurred in 34 (2.3%) patients, and non-access-site MB occurred in 87 (5.8%). The median reduction in hemoglobin was 31 g/L (interquartile range: 19-43) with access-site MB, and 44 g/L (interquartile range: 29-62) with non-access-site MB. After multivariable adjustment, non-access-site MB was independently associated with in-hospital death (adjusted odds ratio [aOR] 4.21; 95% confidence interval [CI] 2.04-8.68), cardiogenic shock (aOR 10.91; 95% CI 5.67-20.98), and cardiac arrest (aOR 5.63; 95% CI 2.88-11.01). Conversely, access-site MB was not associated with adverse in-hospital outcomes. Bleeding-avoidance strategies were used frequently; however, after multivariable adjustment, no single bleeding-avoidance strategy was significantly associated with reduced MB. CONCLUSIONS: In STEMI patients undergoing pPCI, non-access-site MB was independently associated with adverse in-hospital outcomes, whereas access-site MB was not. Additional study of strategies to reduce the incidence and impact of non-access-site MB appears to be warranted.
