To derive a decision instrument, researchers prospectively studied patients aged ≥60 years with syncope or near syncope from 11 U.S. academic centers. The researchers prospectively recorded 13 potential predictor variables, including NT-proBNP and high sensitivity troponin T (hsTnT), which were measured at a core lab and not made available to providers. Local BNP and troponin assays were performed at the discretion of the treating providers. Outcomes were assessed at 30 days by medical record review and phone call.
Of 3686 patients (average age, 73; 51% men), 62% presented with syncope and …
