Predictive Value of Previous Coronary Angiography in Acute Coronary Syndrome

Objective: We aimed to evaluate patients presenting to the emergency department with chest pain in terms of acute coronary syndrome (ACS) risk based on previous coronary angiography (CAG) findings and recent cardiology evaluations.Material and Method: Patients presenting with chest pain were prospectively evaluated and categorized according to the development of major adverse cardiac events (MACE). Prior angiographic findings and recent cardiology evaluations were analyzed for their association with short-term outcomes.Results: A total of 159 patients were included. When patients with and without MACE were compared in terms of significant CAG findings within the last year, no statistically significant difference was observed between the groups (p = 0.576). However, coronary artery disease risk identified during recent cardiology evaluations was significantly higher in patients who developed MACE compared with those who did not (p = 0.022).Conclusion: Prior angiographic stenosis alone does not appear to predict acute adverse cardiac events in emergency presentations. However, recent cardiology evaluations identifying coronary risk may provide more meaningful insight into short-term clinical outcomes.
