Objective: Thrombolysis in Myocardial Infarction Risk Index is a risk stratification model developed to determine the prognosis in ST-segment elevation myocardial infarction patients who underwent fibrinolytic therapy. The information on the effectiveness of Thrombolysis in Myocardial Infarction Risk Index in patients who underwent primary percutaneous coronary intervention is limited. This study aimed to demonstrate the predictive value of Thrombolysis in Myocardial Infarction Risk Index on clinical outcomes in patients presenting with ST-segment elevation myocardial infarction and subsequently undergoing primary percutaneous coronary intervention.

Methods: A total of 963 patients who presented with ST-segment elevation myocardial infarction and subsequently underwent primary percutaneous coronary intervention were reviewed retrospectively. The discriminative power of Thrombolysis in Myocardial Infarction Risk Index for each outcome of congestive heart failure, death, stroke, and myocardial infarction within 1 month and 1 year after admission was assessed.

Results: Congestive heart failure, death, stroke, and myocardial infarction, and the major adverse cardiac events, which is the composite outcome thereof, were higher in the patient groups with high Thrombolysis in Myocardial Infarction Risk Index values (P < .05). Thrombolysis in Myocardial Infarction Risk Index was an independent predictor of the following outcomes: 1-month survival rate [odds ratio:1.054 (1.036-1.073)], 1-year survival rate [odds ratio:1.048 (1.031-1.065)], hospitalization rate due to congestive heart failure within 1 month [odds ratio:1.041(1.026-1.057)], and within 1 year [odds ratio:1.040 (1.024-1.055)]. The Thrombolysis in Myocardial Infarction Risk Index level was found to have good discriminative power for 1-month mortality and 1-year mortality rates (Thrombolysis in Myocardial Infarction Risk Index: 22.76, C-statistic: 0.71-0.68, respectively).

Conclusion: The results of this study indicated that Thrombolysis in Myocardial Infarction Risk Index value is an independent predictor of clinical outcomes such as death and heart failure but not subsequent myocardial infarction in ST-segment elevation myocardial infarction patients. The use of Thrombolysis in Myocardial Infarction Risk Index can be considered in ST-segment elevation myocardial infarction patients who underwent primary percutaneous coronary intervention as it is an easily applicable and important indicator of prognosis.
