Empirically, a significant proportion of patients using direct oral anticoagulation (DOAC) take off-label reduced doses. We aimed to investigate the prevalence, indications, dosages, and bleeding complications of oral anticoagulants on admission to the emergency department. ⋯ Vitamin-K antagonists are still the most widely used drug followed by rivaroxaban. A significant proportion of patients are being prescribed off label-doses. While no difference was found for the respective anticoagulants with respect to bleeding, concomitant aspirin use was a significant predictor for bleeding in our collective.

The Fourth Universal Definition of Myocardial Infarction defines electrocardiographic Q waves as duration ≥30 ms and amplitude ≥1 mm or QS complex in 2 contiguous leads. However, current taskforce criteria may be overly restrictive. Therefore, we investigated the association of isolated, lenient, or strict Q waves with long-term outcome. ⋯ This large contemporary analysis suggests that less-stringent Q-wave criteria carry prognostic value in predicting adverse outcome among primary care patients.
