Abstract

Background: The rate of ventricular arrhythmia in ST-segment elevation myocardial infarction has been significantly reduced by primary percutaneous coronary intervention. However, these events still cause a large short- and long-term disease burden in these patients. Objective: Results of ventricular arrhythmia management in patients with ST-segment elevation myocardial infarction underwent percutaneous coronary intervention. Methods: A observational study of 150 patients diagnosed with ST-segment elevation myocardial infarction who underwent percutaneous coronary intervention and had ventricular arrhythmias during their hospital stay at the hospital Vietnam Heart Institute and Vinh Phuc Provincial General Hospital from September 2022 to July 2023. Results: Rates of clinically significant ventricular arrhythmias at the time of admission was 2.66%; in intervention accounts for 5.33%; after intervention, rate was 2.66% and before discharge, there were no cases of ventricular fibrillation, ventricular tachycardia accounted for 2%. In multivariable regression analysis, TIMI ≤ 2 had the greatest influence on the development of serious, dangerous ventricular arrhythmia with OR = 26.22 and P = 0.001. LVEF contributed to the worsening of ventricular arrhythmias with OR = 6.02 and P = 0.029. Male was a protective factor with OR = 0.12 and P = 0.018. Conclusion: Men can be a protective factor, while heart failure EF ≤ 40% and slow flow phenomenon after intervention have  great impact on the formation of serious and dangerous ventricular arrhythmia.
