Trial Outcomes & Findings for Integrated Management Program Advancing Community Treatment of Atrial Fibrillation (NCT NCT01927367)

NCT ID: NCT01927367

Last Updated: 2021-03-09

Results Overview

Any unplanned hospitalization (admission with an overnight stay in hospital) due to one of the following causes: acute coronary syndrome, pre-syncope /syncope, transient ischemic attack/ stroke, atrial fibrillation, flutter, pulmonary embolism /deep vein thrombosis /systemic embolism, worsening congestive heart failure including pulmonary edema or dyspnea of cardiac origin. AF-related ED visit was predefined as: any presentation with palpitations, rapid heart rate, presyncope or syncope, shortness of breath, transient chest discomfort, or hemodynamic instability resolving with cardioversion or rate-control, not resulting in hospitalization.

Timeframe: 12 months

Major bleeding, as listed above, is to be defined as fatal bleeding and/or symptomatic bleeding in a critical area or organ, such as intracranial, intraspinal, intraocular, retroperitoneal, intra-articular or pericardial, or intramuscular with compartment syndrome and /or overt bleeding causing a fall in hemoglobin level of 20 g/L or more, or leading to transfusion of two or more units of whole blood or red cells.
