Several advanced treatments of high-risk patients with pulmonary embolism have been used in recent decades. We assessed the 19-year national trend in mortality of high-risk patients with pulmonary embolism to determine what impact, if any, advanced therapy might have had on mortality. ⋯ Mortality of high-risk patients with pulmonary embolism has decreased. This decrease can be attributed to improved treatment of patients with shock and with cardiac arrest, and does not reflect advances in therapy for pulmonary embolism.

The concomitant use of direct oral anticoagulants (DOAC) and strong P-glycoprotein (P-gp) and cytochrome P450 3A4 (CYP3A4) inducers may lead to reduced DOAC levels and therapeutic failure. This study aimed to describe DOAC concentrations in patients receiving strong P-gp and CYP3A4 inducers, in relation to individual risk factors for high or low DOAC levels. ⋯ Our data suggest a significant risk of reduced DOAC levels in patients taking strong P-gp and CYP3A4 inducers, especially those without risk factors for drug accumulation. DOAC measurement could help manage this relevant drug-drug interaction.
