etable 1. Clinical Event Definitions Event MI Definition A diagnosis of NSTEMI or STEMI on a hospitalization report, typically defined as ischemic symptoms, and one of the following: a. Cardiac biomarkers with at least one of the values in the abnormal range for that laboratory (typically above the 99 th percentile of the upper reference limit for normal patients) b. ECG changes indicative of new ischemia (new ST-T changes, new left bundle branch block, development of pathological Q-waves [or equivalent findings for true posterior MI]) c. Imaging evidence (e.g., echocardiographic, nuclear) of new loss of viable myocardium or new regional wall motion abnormality Stroke A diagnosis of stroke or cerebrovascular accident on the hospitalization report, typically defined as loss of neurological function caused by an ischemic or hemorrhagic event with residual symptoms at least 24 hours after onset or leading to death. GUSTO bleeding Non CABG-related GUSTO severe or life-threatening bleeding was any intracranial hemorrhage or any bleeding event resulting in substantial hemodynamic compromise requiring treatment. Non CABG-related GUSTO moderate bleeding was any bleeding event resulting in the need for transfusion that was not considered a GUSTO severe or life-threatening bleed. Non CABG-related GUSTO mild bleeding was any other bleeding event that does not require transfusion or cause hemodynamic compromise.
