Usefulness of Clinical Scores for Patient Risk Stratification in Non-ST Elevation Acute Coronary Syndrome: Any Role for Serum Markers of Inflammation?

Risk stratification of patients with unstable angina or non ST-segment elevation myocardial infarction (UA/NSTEMI) is problematic given the heterogeneous presentation of the condition and clinical characteristics of patients. We sought to compare, in acute coronary syndrome patients, the prognostic value of two frequently used risk scores (RS): the Thrombolysis in Myocardial Infarction (TIMI) and the physician’s risk assessment (PRA). We also assessed whether serum biomarkers can increase the prognostic accuracy of clinical RS.
