ABSTRACT
Objective: In patients with acute coronary artery disease, the TIMI risk index (TRI), the thrombolysis in myocardial infarction (TIMI) risk score, and the global registry of acute coronary events (GRACE) risk score (GRS) have all been documented. The aim of this study was to determine the relationship between no-reflow (NRF) and admission TRI, major cardiac events (MACE), and in-hospital mortality in patients undergoing primary percutaneous coronary intervention (P-PCI). Methods: Between March and December 2019, 100 consecutive patients diagnosed with STEMI and treated with PPCI at Tanta Main University Hospital in Tanta, Egypt, were included in the research population. Each patient consented following a thorough history taking, evaluation of coronary risk factors, clinical examination, and electrocardiogram analysis. Additionally, all instances were classified using the Killip method. The GRS, TRS, and TRI values were examined. Results: The GRS, TRS, and TRI scores were significantly associated with increased NRF, MACE, and hospital mortality in STEMI patients treated with P-PCI, suggesting that TRI is a straightforward indicator with fewer parameters that accurately reflects P-PCI success. Conclusion: TRI has been demonstrated to enhance the risk of in-hospital mortality and MACE. TRI uses straightforward and cost-effective ways to test patients who have experienced a STEMI. Additionally, a high TRI may assist in identifying high-risk individuals and developing suitable treatment solutions.
