RESUMEN
OBJECTIVE: The aim was to study the impact of predictors on the duration of inpatient treatment of MI patients. PATIENTS AND METHODS: Materials and methods: We copied data of 462 inpatient medical records of myocardial infarction patients who underwent hospital treatment by different methods (coronary artery stenting, thrombolytic therapy, conventional drug therapy). We determined basic predictors and duration of inpatient treatment of MI patients. Impact of the parameters was studied using Cox regression. RESULTS: Results: We built models of hazard ratios of coronary artery stenting impact on treatment duration for myocardial infarction patients, which proved that this treatment method significantly reduced the treatment duration, even after correction of confounders like sex (HR=1.32; p=0.041), age over 60 (HR=1.31; p=0.048) and heart failure Stage 2A-2B (HR=1.36; p=0.020). CONCLUSION: Conclusions: The results we obtained indicate a statistically significant effect of CAS on MI patients' treatment duration, both separately and combined with multiple effects of confounders, indicating its medical effectiveness and the need for widespread introduction of this treatment method in medical practice in every region of Ukraine.
