Abstract
BACKGROUND: Coronary artery disease (CAD), primarily caused by atherosclerosis, is a leading cause of death, presenting as angina or myocardial infarction. Advances in cardiac imaging, angiography, and procedures like percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery have improved early detection and management of this condition. This report presents the case of a man who experienced worsening exertional chest pain and discomfort while at rest. CASE REPORT: A 66-year-old man with a history of neurogenic syncope and asthma presented at the same-day emergency care (SDEC) unit with worsening exertional chest pain and discomfort whilst at rest. Despite normal ECG and cardiac enzyme results, further cardiac computed tomography angiography (CTCA) revealed significant CAD with moderate stenosis in the right coronary artery (RCA) and severe stenosis at the left anterior descending artery (LAD) bifurcation, leading to CABG surgery. Echocardiography showed a left ventricular ejection fraction of 50-54% with mid-inferior and basal to mid-inferoseptal hypokinesia. The cardiology-cardiothoracic multidisciplinary team concluded that CABG surgery would provide the most durable long-term outcome. CONCLUSION: This case demonstrates the high importance of clinical suspicion of CAD despite normal initial investigations in the early identification and timely investigation as well as the role multidisciplinary teams and CABG can play in the timely management of complex CAD, ultimately leading to improved patient outcomes.
