Purpose: The HAS-BLED score and the left ventricular injection fraction (SVEF) can independently predict clinical results in both patients with acute coronary syndrome. We studied the predictive value of mortality of SVEF and HAS-BLED score combinations in ST-segment elevated myocardial infarction (STEMI) patients treated with primary percutan coronary initiation (PKG). Methods: We examined 588 consecutive STEMI patients applied Primary PKG. HAS-BLED scores for each patient were calculated and the predictive value for mortality was analyzed using the curved area (AUC). Patients were divided into four groups according to HAS-BLED scores. Their HAS-BLED scores were very low risk: 0, low risk: 1, medium risk: 2, high risk: ≥ 3. The first final point was total mortality. The findings: with multi-variable cox regression analysis, the HAS-BLED score (p <0.001) and SVEF (p <0.001) were independent predictors of total mortality. The total mortality rate for only HAS-BLED score was AUC 0.71 (95% CI: 0.66-0.76) . SVEF increased to 0.77 (p <0.001) after added. The increased predictive value of the combination of SVEF and HAS-BLED scores was also shown by net re-classing improvement (NRI = 27.2%, p <0.001) and integrated differentiation improvement (IDI = 0.061, p <0.001). Results: The combination of SVEF with the HAS-BLED score was a forecast for all causes-related mortality in primary PKG applied STEMI patients.
