Effect of Hospital-based Cardiac Rehabilitation on Quality of Life and Physical Capacity in Acute Myocardial Infarction Patients: 2 Years Follow Up

Abstract

Objective: The aim of this study was to investigate the effect of hospital-based cardiac rehabilitation (CR) on quality of life (QOL) and physical functions in patients with acute myocardial infarction (AMI) during 2 years of followup.Methods: All AMI patients referred to the Cardiac Health and Rehabilitation Center (CHRC) were informed about CR and followed for 2 years on an outpatient basis from July 2010 to December 2015. Patients who were divided into a CR group and non-CR group. All patients took home-based self-exercise as CR programs of CHRC and in addition, the CR group received hospital-based supervised exercise training three times a week for 2 months. Both groups were evaluated for physical capacity and QOL at baseline, after 2 months of exercise training, and at 6 months, 1 year, and 2 years of follow-up. Results:The CR group showed significant improvements in physical functioning (PF), physical role functioning, bodily pain, vitality (VT), social role functioning, emotional role functioning, mental health, physical component summary (PCS), and mental component summary at all-time points compared to baseline. At 1 year of follow-up, the CR group displayed significantly greater PF, general health perceptions, VT, and PCS values than the non-CR group. Regarding physical capacity, the CR group exhibited significantly lower resting heart rate and significantly greater maximal oxygen consumption and metabolic equivalents than the non-CR group at 6 months of follow-up. Conclusion:Hospital-based CR was effective in promoting QOL and early improvement in exercise capacity in patients with AMI. Further, the improvement in QOL was maintained for up to 2 years.

Health-Related Quality of Life among Post Myocardial Infarction Patients

“…A study conducted by Kim et al, 2018 in Japan is consistent with our result, which showed that the mean score of the overall HRQL was 62.3 %, indicating a moderate level (Kim et al, 2018). The result of our finding is also consistent with a study conducted in South Korea (Kim and Hwang, 2015).…”

“…The study conducted by Mahmood et al reported that diabetes (DM), high blood pressure (HTN), hypercholesterolemia, smoking, drinking alcohol, obesity, and sedentary lifestyle as risk factors for MI (Mahmood et al, 2014). Other identified risk factors are unhealthy diet, lack of exercise, loneliness and social isolation (Kim et al, 2018). Because of illness manifestations following MI, the healthrelated quality of life (HRQL) could be harmed.…”

Is the Clinical Delivery of Cardiac Rehabilitation in an Australian Setting Associated with Changes in Physical Capacity and Cardiovascular Risk and Are Any Changes Maintained for 12 Months?

“…This is likely a consequence of structural and/or functional changes to the heart as a result of the acute cardiac event and subsequent medical treatment, alongside inactivityrelated declines following the restriction of activity levels due to hospitalisation and recovery [2]. Improvements in physical capacity through CRF and muscular strength assist people to return to or exceed their level of functioning prior to their cardiac event [4]. In addition to improving physical capacity, cardiac rehabilitation aims to reduce the risk of subsequent cardiac events through an improvement in cardiac risk profile [1], and clinical trials have demonstrated that participation in supervised exercise training results in significant improvements in traditional cardiovascular risk factors [1].…”
