Abstract
Resting heart rate (RHR) has been identified as a modifiable risk factor of coronary artery disease (CAD). It was reported that RHR was correlated with the risk of cardiovascular disease (CVD) both in the general population, and in patients with a wide spectrum of cardiovascular disease that consisted of stable CAD, heart failure, as well as acute coronary syndrome (ACS). Objective: To investigate the prognostic value of RHR on short-term outcome of patients undergoing percutaneous coronary intervention (PCI). Patients and methods: This is a single center prospective study enrolling 503 patients undergoing PCI in Cath Lab in Mansoura Medical Specialized Hospital. Data were collected during the period between November 2020 to January 2022. Patients were divided into four groups according to RHR. Patients were followed up In-Cath, during hospital stay and 90 days post discharge for Cardiovascular mortality (CVM) and major adverse cardiovascular events (MACE) Results: Patients presented with ST elevation myocardial infarction (STEMI) and ECG abnormalities were statistically significant higher in patients’ group with RHR <60 and >90 bpm than other groups. Patients presented with Anterior Myocardial infarction (MI) were statistically significant higher in patients’ group with RHR >90 beat/min and those presented with inferior MI were statistically significant higher in patients’ group with RHR <60 bpm than other groups Conclusion: In our study, there was statistically significant association between the patient outcome and the heart rate. Follow up showed statistically significant higher rate of angina in patient group with RHR > 90 beat/min.
