Are cardiac rehabilitation pathways influenced by diabetes:A cohort study

BACKGROUND: Cardiac rehabilitation (CR) is recommended following acute coronary syndrome (ACS). Diabetes is a common long-term condition associated with ACS, and the inclusion of these patients in CR has been less studied. This study examines the referral, uptake, and completion rates in the CR pathway for ACS patients with and without diabetes to identify potential barriers in the CR pathway. METHODS: The study included patients aged 18 or above who were discharged after a diagnosis of ACS in the Central Denmark Region between 1 September 2017 and 31 August 2018. Diabetes information was obtained from three sources. Logistic regression models were used to examine the associations between having diabetes and the three outcomes: non-referral, non-uptake and non-completion. Results were reported as odds ratios (OR) with 95% confidence intervals (CI). RESULTS: A total of 2447 patients were eligible for the study, of which 457 (18.7%) had diabetes. Only non-uptake was found to be significantly associated with diabetes after adjustment for prespecified variables (OR = 1.38, 95% CI 1.01-1.90). Associations for non-referral (OR = 1.11, 95% CI 0.87-1.41) and non-completion (OR = 1.06, 95 %CI 0.73-1.53) were not found to be statistically significant between ACS patients with diabetes and those without diabetes. CONCLUSION: This study highlights a significant disparity in the uptake of CR between patients with and without diabetes following ACS, demonstrating that patients with diabetes require early promotion and increased assistance to enrol in CR

Change in exercise capacity after cardiac rehabilitation following acute coronary syndrome in patients with and without diabetes: a follow-up study

This study aims to compare the changes (continuous and minimal important differences) in exercise capacity between patients with and without diabetes at the end of CR

To what extent is socioeconomic status associated with not taking up and dropout from cardiac rehabilitation: a population-based follow-up study

Objectives High socioeconomic status (SES) has been linked to high referral for cardiac rehabilitation (CR). However, the impact of SES on CR utilisation from enrolment to completion is unclear. The objective of this study was to examine whether indicators of SES are associated with not taking up and dropout from CR.Design A population-based, follow-up study.Setting Hospitals and primary healthcare centres in the Central Denmark Region.Participant Patients diagnosed with ischaemic heart disease (IHD) in the hospital and referred for rehabilitation in the primary healthcare setting from 1 September 2017 to 31 August 2018 (n=2018).Variables Four SES indicators (education, disposable family income, occupation and cohabitant status) were selected because of their established association with cardiovascular health and CR utilisation. Patients were followed up regarding no uptake of or dropout from CR in the primary healthcare setting.Statistical methods The associations between the four SES indicators and either no uptake or dropout from CR were analysed using logistic regression with adjustment for age, sex, nationality and comorbidity.Results Overall, 25% (n=507) of the referred patients did not take up CR and 24% (n=377) of the participators dropped out the CR. All adjusted ORs, except one (education/dropout) demonstrated that low SES compared with high are statistically significantly associated with higher odds of not taking up CR and dropout from CR. The ORs ranged from 1.52, 95% CI 1.13 to 2.04 (education/no uptake) to 2.36, 95% CI 1.60 to 3.46 (occupation/dropout).Conclusions This study highlights that indicators of SES are important markers of CR utilisation following hospitalisation for IHD

Benefits of cardiac rehabilitation following acute coronary syndrome for patients with and without diabetes : a systematic review and meta-analysis

AIM: The 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. METHODS: Five 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. RESULTS: A 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)). CONCLUSION: The 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
