Abstract

Problem: Heart rate is one of the important factors in treatment and prognosis of coronary artery disease, in general and chronic coronary syndrome, in particular. Objective: To survey the heart rate in outpatients with chronic coronary syndrome. Subjects and research methods: A descriptive cross-sectional study was performed on 150 patients with chronic coronary syndrome at Outpatient Department, Cardiology Clinic, University Medical Center Ho Chi Minh city, campus 1, from March to May 2022. Results: The mean heart rate was 73.9 ± 12.4 bpm (beats per minute). 13.3% of patients reached the target heart rate within 55-60 bpm. The prevalence of patients with heart rate ≤60, 61-69, ≥70 bpm was 15.3%, 23.3% and 61.3%, respectively. Patients with heart rate ≥70 bpm had more angina pectoris, more incidence of atrial fibrillation and lower rate of beta-blocker use. Conclusion: The rate of patient with chronic coronary syndrome reaching target heart rate as recommendation of AHA 2012 and ESC 2019 was still very low.
