We present a noteworthy case of dual pathology in a 62-year-old female with recurrent chest pains and extensive cardiac risk factors. From computed tomography coronary angiography, a left anterior descending artery lesion was identified and successfully revascularized with a drug-eluting stent. Due to persistent chest pain, further investigation revealed a descending aortic dissection, which was conservatively managed. This case highlights the potential challenges of diagnosis in dual pathologies and emphasizes initiating appropriate investigations. <Learning objectives: It is important to consider all differential diagnoses in atypical presentations of possible acute coronary syndrome. As clinical presentations and risk factors may be similar, initiating appropriate diagnostic and management pathways are crucial to avoid misdiagnosis.>.
