Key result
Interhospital transfer linked to ~20% lower 30-day mortality in acute myocardial infarction.
Why the study?
United States Air Force regulations do not recommend routine movement of recently stabilized AMI patients, but frequent requests for aeromedical transport occur in Europe.
Cohort (n=184,295)

Associated lower AMI mortality with transfer may support reevaluation of aeromedical restrictions; challenges consensus yet remains hypothesis-generating.
United States Air Force regulations currently do not recommend the routine movement of recently stabilized patients diagnosed with acute myocardial infarctions. However, U.S. Department of Defense and embassy physicians throughout Europe continually request aeromedical movement of these patients. Therefore, a year-long prospective case review of acute myocardial infarction (AMI) patient movement within the military aeromedical system in Europe was undertaken to evaluate the need for and safety of transporting these patients. This case review, combined with the literature, suggests that recently stabilized AMI patients, with appropriate pre-flight preparation and in-flight care, can tolerate exposure to the stresses of flight and can be safely airlifted.

Connor et al. (1995) conducted a cohort in Acute Myocardial Infarction (AMI) (n=184,295). Interhospital transfer vs. Non-transferred patients was evaluated on 30-day mortality (OR 0.80, 95% CI 0.76-0.84, p=<0.001). Interhospital transfer was associated with a lower risk of 30-day mortality compared to non-transferred patients hospitalized for acute myocardial infarction.
