Correlation between Heart Rate Recovery & Global Longitudinal Strain in Heart Failure Patients Subjected to Cardiac Rehabilitation

Abstract

Abstract Background Cardiac rehabilitation is a medically supervised program designed to improve cardiovascular outcomes after MI, heart failure, angioplasty, or heart surgery. It is a complex intervention that involves a variety of therapies, including supervised exercise training, health education and risk factor modification, behavior change, social and psychological support. Objective To study the correlation between heart rate recovery & global longitudinal strain in heart failure patients subjected to cardiac rehabilitation. Patients and Methods This study was conducted in the cardiac rehabilitation (CR) unit in the cardiology department of Ain Shams University hospital between December 2019 and December 2020 to investigate the correlation between heart rate recovery & global longitudinal strain in heart failure patients subjected to cardiac rehabilitation. Results Our study is the first study that investigated the correlation between HRR and GLS in ischemic heart failure patients subjected to cardiac rehabilitation. Conclusion Exercise-based cardiac rehabilitation leads to improvement in the functional capacity of ischemic heart failure patients as reflected by the improvement in HRR and also leads to IMPROVEMENT in LV functions as reflected by the improvement in GLS. Moreover, METs and HR reserve was improved significantly with CR.
