Abstract

Background: Several studies showed that there is high correlation between heart rate and high adverse outcomes rates. Objective: The aim of the current study is to investigate the effect of heart rate on admission in hospital-outcome of patients undergoing primary percutaneous coronary intervention.
Patients and methods: Over the course of 7 months, from July 2019 to January 2020, 63 patients were enrolled in a prospective comparative study at the Cardiology Department of Zagazig University Hospitals. Enrolled patients were diagnosed with acute ST-elevation myocardial infarction (STEMI) and then treated with primary percutaneous coronary intervention. Ejection fraction and coronary angioplasty were assessed in all patients.
Results: Significant positive correlations were found between age and heart rate above 100 bpm, also between systolic blood pressure and diastolic blood pressure, with significant negative correlations between systolic blood pressure and left ventricular end-diastolic volume (LVEDV), between diastolic blood pressure and LVEDV, and also between ejection fraction and LVEDV and left ventricular end-systolic volume (LVESV). Among group with heart rate above 100 bpm a significant positive correlation between LVEDV and LVESV was found.
Conclusion: The presence of admission tachycardia was linked to increased risk of severe adverse cardiac events in patients with STEMI following primary percutaneous coronary intervention, despite the lack of an association between admission bradycardia and serious cardiac outcomes. Further studies with large sample size are recommended to confirm the current results.
