Factors in Predicting Short Term Mortality in ST Elevation Myocardial Infarction Patients Undergoing Primary Percutaneous Coronary Intervention

Background: Percutaneous coronary angiography and intervention have been applied in the diagnosis and treatment of coronary artery disease at Gia Dinh People's Hospital since April 2009 until now with very positive results, contributing to improving the quality of diagnosis and treatment. Treating cardiovascular patients with high technology. However, there is currently no research to help evaluate performance as well as prognostic factors affecting treatment outcomes at this unit. Therefore, we conducted this study with the research question: Short-term mortality rate in patients with ST-elevation acute myocardial infarction undergoing primary percutaneous coronary intervention at Gia Dinh People's Hospital. What is the year 2022 - 2023? What factors predict short-term mortality in patients with acute ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Materials and methods: There were 163 patients at the Gia Dinh People's Hospital from November 2022 to September, 2023. This was a cohort study.

Results: In-hospital and 30-day mortality rates after intervention were 4.29% and 4.91%, respectively. Short-term mortality prognostic factors include systolic blood pressure < 100 mmHg, arrhythmia at admission, TIMI score > 6, cardiogenic shock before the procedure, blood potassium concentration with mortality rate within 30 days after PCI, with p < 0.05.

Conclusion: In clinical practice, attention should be paid to factors predicting 30-day mortality in STEMI patients include systolic blood pressure < 100 mmHg, arrhythmia at admission, TIMI score > 6, cardiogenic shock before the procedure, blood potassium concentration with mortality rate within 30 days after PCI.
