This study sought to validate European Society of Cardiology guideline-endorsed high-risk features of stent-related recurrent ischemic events for the prediction of ischemic and bleeding outcomes including a stratification according to the PRECISE-DAPT score estimated bleeding risk.
BACKGROUND
The 2017 European Society of Cardiology-focused update on dual-antiplatelet therapy endorsed high-risk features of stent-related recurrent ischemic events. Because patients with high ischemic risk also have an increased bleeding risk, appropriate risk stratification for ischemic and bleeding events is crucial.
METHODS
Between January 2009 and December 2015, a total of 10,236 consecutive patients undergoing clinically indicated percutaneous coronary intervention were prospectively included in the Bern PCI Registry. Guideline-endorsed high-risk features were retrospectively assessed. The primary ischemic endpoint was device-oriented composite endpoint (DOCE; cardiac death, target-vessel myocardial infarction, and target lesion revascularization) at 1 year, and the primary bleeding endpoint was Bleeding Academic Research Consortium (BARC) 3-5 at 1 year.
RESULTS
A total of 5,323 (52.0%) patients had at least 1 high-risk feature. Among patients with high-risk features, DOCE (12.3% vs. 5.5%; p < 0.001) and BARC 3-5 bleeding (4.9% vs. 2.2%; p < 0.001) occurred more frequently compared with those without. There was a graded risk increase for DOCE (0: 5.5%; 1 to 2: 11.3%; and ≥3: 16.7%; p < 0.001) and BARC 3-5 bleeding (0: 2.2%; 1 to 2: 4.5%; and ≥3: 6.6%; p < 0.001) as the number of high-risk features increased. High-PRECISE-DAPT score (≥25) was associated with an increased risk of DOCE and BARC 3-5 bleeding, irrespective of number of high-risk features.
CONCLUSIONS
The European Society of Cardiology guideline-endorsed high-risk features were associated with increased ischemic and bleeding risks following percutaneous coronary intervention in routine clinical practice. (CARDIOBASE Bern PCI Registry; NCT02241291).
