Goriki et al reported a simple risk score for identifying a patient with acute myocardial infarction who is at risk for major bleeding. The authors are from Saga University and affiliated hospitals in Saga, Japan.
Patient selection: hospitalized patient after acute myocardial infarction
Outcome: major bleeding (severe or life-threatening; intracranial; hemodynamic compromise requiring treatment)
Parameters:
(1) hemoglobin in g/dL
(2) white blood cell count per microliter
(3) platelet count per microliter
(4) serum albumin in g/dL
(5) eGFR in mL per min per 1.73 square meters
