Correlation between Timi Risk Score and Clinical Outcome in Patients with Unstable Angina Pectoris

Given Taking that the TIMI score is a major predictor of MACE, this study aimed to determine the value of the TIMI risk score in predicting poor outcomes (death, myocardial infarction, recurrent pain) in patients presenting with unstable angina pectoris in short-term observation. A total of 107 patients with APns were examined at the Clinical Centre Kragujevac and were included in the investigation. The TIMI score was determined on the first day of hospitalization. During hospitalization, the following factors were also observed: troponin, ECG evolution, further therapy (pharmacologic therapy and/or emergency PCI or CABG), age, hypertension and hyperlipidaemia. The low-risk group (TIMI 0 - 2) included 30.8% of patients, whereas 47.6% of patients were in the intermediate-risk group (TIMI 3 - 4), and 21.5% of patients were in the high-risk group (TIMI 5 - 7). Good outcomes (without adverse event) and poor outcomes (death, myocardial infarction, and recurring chest pain) were dependent on the TIMI risk score. The increase in TIMI risk score per one unit increased the risk of a poor outcome by 54%. Troponin and TIMI risk score were positively correlated. Our results suggest that the TIMI risk score may be a reliable predictor of a poor outcome (MACE) during the short-term observation of patients with APns. Moreover, patients identified as high-risk benefit from early invasive PCI, enoxaparin and Gp IIb/IIIa inhibitors. Th us, routine use of the TIMI risk score at admission may reduce the number of patients not recognized as high-risk.
