A Primer on Simple Congenital Cardiac Shunt Lesions.

The PRECISE-DAPT score predicts the bleeding risk in patients treated with dual antiplatelet treatment after PCI. We asess the prediction power of the score in patients suffering from non–ST elevation acute coronary syndromes. Our cohort included 862 patients from Buenos Aires 1 registry. The PRECISE-DAPT score was calculated upon admission and the follow up period was 15 months. The score as a continuous variable had low to moderate ability to predict bleeding events BARC 2, 3 or 5 (c-statistics 0.58 [95% CI, 0.52-0.61]); moderate at BARC 3 or 5 (c-statistics 0.72 [95% CI, 0.64-0.78]), and poor for MACE (c-statistics 0.49 [95% CI, 0,45-0.51]). PRECISE-DAPT score as a dichotomous variable (≥25, n= 210 [24%]) was associated with very high risk of bleeding (HR 2.1) and ischemic events (HR 1.9, 95% CI 1.8-2.1). As conclusion, PRECISE-DAPT score ≥25 was able to identify a subgroup of patients with high bleeding, and thrombotic events.
