Examining Renal Impairment as a Risk Factor for Acute Coronary Syndrome: A Prospective Observational Study

There is an independent association between eGFR and acute coronary syndrome risk in patients presenting to the ED with chest pain; this association is independent of age, traditional cardiac risk factors, medical history, troponin level, and ECG findings. Reduced eGFR should be considered an acute coronary syndrome risk factor, and clinicians should maintain high clinical suspicion for acute coronary syndrome in patients with abnormal renal function results regardless of whether they have known kidney disease, traditional acute coronary syndrome risk factors, or abnormal diagnostic test results. Risk stratification tools should include reduced eGFR as a high-risk feature.
