Diagnostic dilemmas in acute type A aortic dissection with acute myocardial infarction: A fatal misdiagnosis case and improvement strategies

This case underscores the need for clinicians to be alert to the coexistence of TA-AAD and AMI in chest pain patients: percutaneous coronary intervention may exacerbate dissection progression and surgical hemostatic difficulty, while misdiagnosis combined with inappropriate treatment markedly increases mortality. Analyzing this fatal misdiagnosis provides practical references for optimizing diagnostic/therapeutic workflows, promoting multidisciplinary team involvement in decision-making, and reducing misdiagnosis-related adverse outcomes - ultimately offering valuable clinical guidance for improving patient survival.
