Objectives: We sought to evaluate mortality predictors and the role of new-generation drug-eluting stents (NG-DES) in stent thrombosis (ST) management. Background: No data are available regarding the outcome of patients with ST after interventional management that includes exclusively NG-DES. Methods: Patients with definite ST of DES or BMS who underwent urgent/emergent angiography between 2015 and 2018 at our institution were considered for the study. After excluding patients who achieved TIMI-flow<2 after intervention or received an old-generation stent, 131 patients were included. Management classification was stent or non-stent treatment (medical management, thromboaspiration, balloon-angioplasty). Follow-up was performed to document all-cause death (ACD) and target-lesion-revascularization (TLR) that was used for censorship. Results: Mode of presentation was STEMI in 88% and UA/NSTEMI in 12%. Type of ST was early, late, and very late in 11, 4, and 85%, respectively. Eighty four patients received stent and 47 non-stent treatment. After 926 ± 34 days, 21 ACDs, 7 TLRs and no cases of definite, recurrent ST were observed. Univariate predictors of in-hospital mortality were LVEF and presentation with shock or cardiac arrest. For patients discharged alive, non-stent treatment (HR 4.2, p = .01), TIMI-2 flow (HR 7.4, p = .002) and GFR < 60 mL/min (HR 3.8, p = .01) were independent predictors of ACD. The stent-treatment group had significantly better ACD-free survival after discharge, both unadjusted (p = .022) and adjusted (p = .018). Conclusions: After ST management, different predictors were observed for in-hospital mortality and mortality in patients discharged alive. The better outcome with NG-DES treatment is a novel observation, warranting further studies to elucidate if it is associated with stent-related or patient-related factors.
