摘要
Objective To summarize cases of acute myocardial infarction(AMI)after tranexamic acid(TXA)administration.Methods Electronic databases were searched to identify all case reports presenting AMI after use of TXA.Iwo authors independently extracted data of patients'manifestation,examinations,medical history,treatment and outcome.Results Our search yielded seven case reports including seven patients.Among the seven reports,two were from USA,and the other five were from India,Turkey,UK,Italy and France,respectively.Of the seven patients aged between 28-and 77-year-old who developed AMI after TXA,five patients were female and two were male.TXA was prescribed for four patients to reduce surgical bleeding,for two patients to treat menorrhagia and for one patient to manage hemoptysis.The diagnosis of AMI was made based upon patients'symptoms,ECG,myo car dium-specific enzymes,and confirmed by coronary angiography.Coronary stents were placed in four patients,for whom anti-platelet and anti-coagulation drugs were prescribed.No death or major cardiovascular events were reported during hospitalization and follow-up.Conclusion These case reports suggested a possible association of TXA administration and an increased risk of AMI,even in patients with relatively low thrombotic risk.
