The most frequently reported medical emergencies during flights are syncope and respiratory distress [3, 4].

Highlights • A single troponin measurement may be used to rule-out myocardial infarction (MI). • Rule-out of MI was highly safe in late presenters, i.e. presentation >3 h. • Early presenters with MI had lower troponin values than late presenters. • However, rule-out of MI was equally safe in early presenters. • No patients with MI were missed when using a single-testing algorithm at admission.
