Determinants of Functional Improvement After Cardiac Rehabilitation in Acute Coronary Syndrome.

ABSTRACT:

Introduction

Cardiac rehabilitation (CR) is an effective tool for secondary prevention after acute coronary syndrome (ACS).

Aim

Aim of our study was to find the significant determinants of exercise capacity (evaluated with the six-minute walking test-6-MWT) and functional improvement in patients undergoing CR after an ACS.

Methods

The study group included 298 patients (mean age 61.6 ± 10.2 years; males 80.2%) who, after ACS, were enrolled in CR program at Niguarda Hospital in Milan from 2015 to 2018. For all patients, we collected anamnestic, clinical and instrumental cardiological data. All patients performed a 6-MWT at the beginning (6-MWT-1) and at the end (6-MWT-2) of CR program. Δ meters were used to represent functional improvement.

Results

Multiple linear regression models were carried out for 6-MWT-1, 6-MWT-2, Δ meters and % Δ meters. Standardized regression coefficients showed that age (β = - 0.237; p < 0.001), BMI (β = - 0.116; p = 0.006) and heart rate (β = - 0.082; p = 0.040) were determinants of exercise capacity (6MWT-1 and 2), whereas age (β = -.231; p = 0.004), sex (β = - 0.187; p = 0.008) and BMI (β = - 0.164; p = 0.022) were determinants of functional improvement (Δ meters).

Conclusions

Our data showed that functional improvement after CR in ACS patients is mainly related to non-cardiological variables. Instead it is related to intrinsic factors, both modifiable (BMI) and non-modifiable (age, sex).

Project description:Though clinical practice guidelines (CPGs) for cardiac rehabilitation (CR) are an effective and widely used treatment method worldwide, they are as yet not widely accepted in Korea. Given that cardiovascular (CV) disease is the second leading cause of death in Korea, it is urgent that CR programs be developed. In 2008, the Government of Korea implemented CR programs at 11 university hospitals as part of its Regional Cardio-Cerebrovascular Center Project, and 3 additional medical facilities will be added in 2019. In addition, owing to the promotion of CR nationwide and the introduction of CR insurance benefits, 40 medical institutions nationwide have begun CR programs even as a growing number of medical institutions are preparing to offer CR. The purpose of this research was to develop evidence-based CPGs to support CR implementation in Korea. This study is based on an analysis of CPGs elsewhere in the world, an extensive literature search, a systematic analysis of multiple randomized control trials, and a CPG management, development, and assessment committee comprised of thirty-three authors-primarily rehabilitation specialists, cardiologists, and thoracic surgeons in 21 university hospitals and 2 general hospitals. Twelve consultants, primarily rehabilitation, sports medicine, and preventive medicine specialists, CPG experts, nurses, physical therapists, clinical nutritionists, and library and information experts participated in the research and development of these CPGs. After the draft guidelines were developed, 3 rounds of public hearings were held with staff members from relevant academic societies and stakeholders, after which the guidelines were further reviewed and modified. CR involves a more cost-effective use of healthcare resources relative to that of general treatments, and the exercise component of CR lowers CV mortality and readmission rates, regardless of the type of coronary heart disease and type and setting of CR. Individualized CR programs should be considered together with various factors, including differences in heart function and lifestyle, and doing so will boost participation and adherence with the CR program, ultimately meeting the final goals of the program, namely reducing the recurrence of myocardial infarction and mortality rates.

Project description:Background and Objectives: Nearly 23% of elderly patients hospitalized due to acute coronary syndrome have reduced muscle strength. It is assumed that these patients would better benefit from a complex training-a combination of endurance, strength, balance, coordination, and flexibility-in order to reduce the loss of muscle strength and mass and improve functional capacity. The aim of this study was to assess the effectiveness and safety of two different complementary resistance and balance training programs during short-term cardiac rehabilitation (CR) in elderly patients after a percutaneous or surgical intervention due to acute coronary syndrome. Materials and Methods: This randomized controlled trial was conducted from January 2020 to February 2021 in one Lithuanian rehabilitation hospital. A total of 63 participants who met the inclusion criteria were randomly assigned to three groups (at the ratio of 1:1:1): control (CG, n = 19), intervention 1 (IG-1, n = 26), and intervention 2 (IG-2, n = 18). All the patients attended a usual inpatient CR program of a mean duration of 18.7 ± 1.7 days, while the patients assigned to the intervention groups (IG-1 and IG-2) additionally received different resistance and balance training programs three days a week. Functional capacity, with 6-minute walk test (6MWT) and cardiopulmonary exercise testing (CPET), as well as physical performance, with the short physical performance battery (SPPB) test and one repetition maximum test (1RM) for leg press, were assessed at baseline and after CR. Results: The mean age of the participants was 72.9 ± 5.5 years; 73% were men. All parameters of functional capacity and physical performance improved significantly after CR (p < 0.05), except for peak VO2 that improved only in the IG-1. Comparison of CR effectiveness among the groups revealed no significant differences. Conclusions: All three rehabilitation programs were safe and well tolerated by elderly patients aged ≥65 years as well as improved functional capacity (6-minute walk distance and peak workload) and physical performance (SPPB and 1RM). Complementary resistance and balance training with traditional physical therapy means and exercises with mechanical devices did not show greater benefits for the results of physical performance compared with the usual CR program.

Project description:ObjectiveTo evaluate the association between socioeconomic status (SES) and referral to cardiac rehabilitation (CR) after incident acute coronary syndrome (ACS) by dividing the referral process into three phases: (1) informed about CR, (2) willingness to participate in CR, (3) and assigned CR setting.DesignCross-sectional study.SettingDepartment of Cardiology at a Danish University Hospital from 1 January 2011 to 31 December 2014.ParticipantsA total of 1229 patients assessed for CR during hospitalisation with ACS were prospectively registered in the Rehab-North Register from 2011 to 2014. SES was assessed using data from national registers, concerning: personal income, occupational status, educational level and civil status. Patients were excluded if one of the following criteria was fulfilled: (1) missing data on SES, or (2) acceptable reason for not informing patients about CR (treatment with coronary artery bypass grafting, transfer to another hospital, still under treatment or death).Main outcome measuresOutcomes were defined by dividing the referral process into three phases: (1) informed about CR, (2) willingness to participate, and (3) assigned CR setting (in-hospital/community centre) after ACS.ResultsA total of 854 (69.5 %) patients were referred to CR. After adjustment for age, gender, ACS diagnosis (ST-elevated myocardial infarction, non-ST-elevated myocardial infarction, unstable angina pectoris) and comorbidity, high income had the strongest association of referral to CR in all three phases (informed about CR: OR 2.17, 95% CI 1.01 to 4.64; willingness to participate in CR: OR 1.55, 95% CI 1.02 to 2.35; assigned in-hospital CR: OR 1.47, 95% CI 0.91 to 2.36). Educational level showed similar tendencies, however not statistically significant. The results did not vary according to gender.ConclusionThis is the first study to investigate the referral process to CR using a three-phase structure. It suggests income and education to influence all phases in the referral process to CR after ACS.

Project description:AimThe benefits of cardiac rehabilitation (CR) after acute coronary syndrome (ACS) are well established. However, the relative benefit of CR in those with comorbidities, including diabetes, is not well understood. This systematic review and meta-analysis examined the benefit of CR on exercise capacity and secondary outcomes in ACS patients with a co-diagnosis of diabetes compared to those without.MethodsFive databases were searched in May 2021 for randomised controlled trials (RCTs) and observational studies reporting CR outcomes in ACS patients with and without diabetes. The primary outcome of this study was exercise capacity expressed as metabolic equivalents (METs) at the end of CR and ≥ 12-month follow-up. Secondary outcomes included health-related quality of life, cardiovascular- and diabetes-related outcomes, lifestyle-related outcomes, psychological wellbeing, and return to work. If relevant/possible, studies were pooled using random-effects meta-analysis.ResultsA total of 28 studies were included, of which 20 reported exercise capacity and 18 reported secondary outcomes. Overall, the studies were judged to have a high risk of bias. Meta-analysis of exercise capacity was undertaken based on 18 studies (no RCTs) including 15,288 patients, of whom 3369 had diabetes. This analysis showed a statistically significant smaller difference in the change in METs in ACS patients with diabetes (standardised mean difference (SMD) from baseline to end of CR: - 0.15 (95% CI: - 0.24 to - 0.06); SMD at the ≥ 12-month follow-up: - 0.16 (95% CI: - 0.23 to - 0.10, four studies)).ConclusionThe benefit of CR on exercise capacity in ACS patients was lower in those with diabetes than in those without diabetes. Given the small magnitude of this difference and the substantial heterogeneity in the results of the study caused by diverse study designs and methodologies, further research is needed to confirm our findings. Future work should seek to eliminate bias in observational studies and evaluate CR based on comprehensive outcomes.
