Natsuaki et al reported scores for predicting complications for a patient who has undergone a percutaneous coronary intervention (PCI). One score relates to thrombotic risk and a second relates to bleeding risk. The authors are from multiple institutions in Japan.
Patient selection: status post percutaneous coronary intervention (PCI)
Parameters:
(1) heart failure
(2) prior myocardial infarction
(3) peripheral vascular disease
(4) severe chronic kidney disease (eGFR < 30 mL per min per 1.73 sq m)
(5) atrial fibrillation
(6) platelet count per microliter
(7) malignancy
