    The study identified independent risk factors for ticagrelor-induced dyspnea in patients with acute coronary syndrome.

  • 2

    Plasma levels of ticagrelor and its active metabolite, AR-C124910XX, were measured in 102 patients undergoing antiplatelet therapy.

  • 3

    Patients who developed dyspnea had significantly lower LDH levels and ticagrelor metabolite ratios compared to those who did not.

  • 4

    Higher peak concentrations of ticagrelor were associated with the occurrence of dyspnea, indicating a potential risk factor.

  • 5

    The study emphasizes the need for therapeutic drug monitoring of ticagrelor to manage the risk of dyspnea in ACS patients.
