Summary of the best evidence for risk stratification of exercise rehabilitation in patients with a cardiac implantable electronic device

Background

Hierarchical management of sports risk is highly critical to ensure the safety of sports rehabilitation. Early identification, timely prevention and control of sports-related risk factors, and enhanced supervision and guidance can provide a basis for the formulation of sports programmes and the setting of sports monitoring levels.

Objective

This study aimed to retrieve, evaluate, and integrate evidence for the stratified management of motor risk in patients with a cardiac implantable electronic device (CIED).

Methods

We searched for evidence according to the "6S" model of evidence-based resources. CNKI, VIP, Wanfang Data, CBM, PubMed, Cochrane Iibrary, CINAHL, EMbase, Web of Science, BMJ Best Practice, Up To Date, and International Guidelines Collaboration Network were searched from inception to February 2024. To search for evidence on stratified management of motor risk in patients with CIEDs, this research includes guidelines, systematic reviews, meta-analyses, expert consensus, clinical decision-making, and randomized controlled trials. After methodological quality evaluation, the evidence was extracted and summarized accordingly.

Results

According to the inclusion and exclusion criteria, 16 pieces of evidence were screened, including 5 guidelines, 1 clinical decision-making, 5 systematic reviews, 4 expert consensus, and 1 randomized controlled trial. After reading, extracting, and categorizing, 34 pieces of evidence in 4 areas were identified, namely, screening and assessment of exercise risk in CIEDs, exercise monitoring, implementation of exercise prescriptions, and prevention and management of exercise-related risks.

Conclusions

This study provides the best evidence for the prevention and management of exercise risk in patients with CIEDs, clarifies the role of nurses in evaluating, monitoring, and educating patients undergoing motor rehabilitation, and provides a basis for the formulation of clinically feasible rehabilitation programs.

Identifying Elements for a Cardiac Rehabilitation Program for Caregivers: An International Delphi Consensus

Background/Objectives: Caregivers of patients with heart disease may often feel physically, emotionally, and psychologically overwhelmed by their role. The analysis of cardiac rehabilitation (CR) components and caregivers' needs suggests that some interventions may benefit them. Therefore, this study aimed to identify a consensus on the CR components targeting caregivers of patients with heart disease. Methods: A three-round international e-Delphi study with experts on CR was conducted. In round 1, experts provided an electronic level of agreement on a set of initial recommendations originating from a previous scoping review. In round 2, experts were asked to re-rate the same items after feedback and summary data were provided from round 1. In round 3, the same experts were asked to re-rate items that did not reach a consensus from round 2. Results: A total of 57 experts were contacted via e-mail to participate in the Delphi panel, and 43 participated. The final version presents seven recommendations for caregivers of patients with heart disease in CR programs. Conclusions: These recommendations are an overview of the evidence and represent a tool for professionals to adapt to their context in the different stages of CR, integrating the caregiver as a care focus and as support for their sick family members. By identifying the components/interventions, there is potential to benchmark the development of a cardiac rehabilitation strategy to be used and tested by the healthcare team for optimizing the health and role of these caregivers.

Cardiac Rehabilitation to Inpatient Heart Transplant-HRN4HTx Intervention Protocol

Heart transplantation is the gold-standard treatment for terminal heart failure. Despite being successful, pre- and post-transplant limitations interfere with patients' functional capacity, self-care, and quality of life post-surgery. Rehabilitation is necessary to address these limitations, prevent complications, and promote a safe return home. This study analyzes the safety of a phase 1 cardiac rehabilitation protocol (RN4HTx) in heart transplant patients and its effects on self-care capacity. A quantitative, descriptive study was conducted with 19 heart transplant recipients. The protocol was implemented in collaboration with a rehabilitation professional, who monitored adverse events, hemodynamic variables, self-care capacity (Barthel) pre- and post-transplant, and functional capacity at discharge (6 min walk test). The results showed that 68.42% of recipients were men, with an average age of 50.21 years and 15 days of hospitalization post-transplant. Approximately 73.68% of recipients were transferred from other wards with changes in functional capacity. All patients progressed to the final stage of the program without adverse events. There was a notable improvement in self-care capacity before and after transplantation, with a measure of functional status of 310.035 m (6MWT). The study found that RN4HTx is a feasible cardiac rehabilitation program without adverse events in the immediate postoperative period following heart transplantation, positively impacting functional recovery and therapeutic self-care capacity, thus increasing the safety of returning home. This study was retrospectively registered on Clinical Trials-NCT06552390.

Psychological factors associated with exercise self-efficacy in the recipients of an implantable cardioverter defibrillator

BACKGROUND

Insufficient exercise affects the health of patients who have implantable cardioverter defibrillators (ICD). The purpose of this study was to investigate the correlations between exercise self-efficacy (ESE) and its associated psychological factors in ICD recipients.

METHODS

This cross-sectional study included individuals who had undergone ICD implantation at the cardiology department of a medical centre in Taiwan. A face-to-face survey was conducted. The survey questionnaire included questions regarding the participants' demographics, perceived health (PH), ICD shock-related anxiety (ICD-SRA), self-care self-efficacy (SSE), perceived exercise benefit (PE-benefit), perceived exercise barrier (PE-barrier), and ESE. Data were analysed using SPSS 20.0 Software. Stepwise multiple regression analyses were also performed to evaluate the predictive effects of the aforementioned factors on ESE.

RESULTS

A total of 52 ICD recipients were enrolled. ESE was negatively correlated with ICD-SRA (r = -0.511; p < 0.01) and PE-barrier (r = -0.563; p < 0.01), but positively correlated with SSE (r = 0.339; p < 0.05) and PE-benefit (r = 0.464; p < 0.01). The stepwise multiple regression analysis revealed that PE-barrier, PE-benefit, and ICD-SRA effectively predicted ESE in the participants.

CONCLUSIONS

ESE may be improved by overcoming PE-barrier, ICD-SRA and enhancing PE-benefit. Consequently, improving ESE may enhance the health benefits of exercise.

Single- Versus Dual-Chamber Implantable Cardioverter-Defibrillator for Primary Prevention of Sudden Cardiac Death in the United States

Background Routine addition of an atrial lead during an implantable cardioverter-defibrillator (ICD) implantation for primary prevention of sudden cardiac death, in patients without pacing indications, was not shown beneficial in contemporary studies. We aimed to investigate the use and safety of single- versus dual-chamber ICD implantations in these patients. Methods and Results Using the National Inpatient Sample database, we identified patients with no pacing indications who underwent primary-prevention ICD implantation in the United States between 2015 and 2019. Sociodemographic and clinical characteristics, as well as in-hospital complications, were analyzed. Multivariable logistic regression was used to identify predictors of in-hospital complications. An estimated total of 15 940 patients, underwent ICD implantation for primary prevention of sudden cardiac death during the study period, 8860 (55.6%) received a dual-chamber ICD. The mean age was 64 years, and 66% were men. In-hospital complication rates in the dual-chamber ICD and single-chamber ICD group were 12.8% and 10.7%, respectively (P<0.001), driven by increased rates of pneumothorax/hemothorax (4.6% versus 3.4%; P<0.001) and lead dislodgement (3.6% versus 2.3%; P<0.001) in the dual-chamber ICD group. Multivariable analyses confirmed atrial lead addition as an independent predictor for "any complications" (odds ratio [OR], 1.1 [95% CI, 1.0-1.2]), for pneumo/hemothorax (odds ratio, 1.1 [95% CI, 1.0-1.4]), and for lead dislodgement (odds ratio, 1.3 [95% CI, 1.1-1.6]). Conclusions Despite lack of evidence for clinical benefit, dual-chamber ICDs are implanted for primary prevention of sudden cardiac death in a majority of patients who do not have pacing indication. This practice is associated with increased risk of periprocedural complications. Avoidance of routine implantation of atrial leads will likely improve safety outcomes.

Korean Society of Heart Failure Guidelines for the Management of Heart Failure: Treatment

The Korean Society of Heart Failure (KSHF) guidelines aim to provide physicians with evidence-based recommendations for the management of patients with heart failure (HF). After the first introduction of the KSHF guidelines in 2016, newer therapies for HF with reduced ejection fraction, HF with mildly reduced ejection fraction, and HF with preserved ejection fraction have since emerged. The current version has been updated based on international guidelines and research data on Korean patients with HF. Herein, we present Part II of these guidelines, which comprises treatment strategies to improve the outcomes of patients with HF.

Clinical Determinants and Barriers to Cardiac Rehabilitation Enrollment of Patients with Heart Failure with Reduced Ejection Fraction: A Single-Center Study in Portugal

Despite cardiac rehabilitation (CR) being a recommended treatment for patients with heart failure with reduced ejection fraction (HFrEF), it is still underused. This study investigated the clinical determinants and barriers to enrollment in a CR program for HFrEF patients. We conducted a cohort study using the Cardiac Rehabilitation Barriers Scale (CRBS) to assess the reason for non-enrollment. Of 214 HFrEF patients, 65% had not been enrolled in CR. Patients not enrolled in CR programs were older (63 vs. 58 years; p < 0.01) and were more likely to have chronic obstructive pulmonary disease (COPD) (20% vs. 5%; p < 0.01). Patients enrolled in CR were more likely to be treated with sacubitril/valsartan (34% vs. 19%; p = 0.01), mineralocorticoid receptor antagonists (84% vs. 72%; p = 0.04), an implantable cardioverter defibrillator (ICD) (41% vs. 20%; p < 0.01), and cardiac resynchronization therapy (21% vs. 10%; p = 0.03). Multivariate analysis revealed that age (adjusted OR 1.04; 95% CI 1.01−1.07), higher education level (adjusted OR 3.31; 95% CI 1.63−6.70), stroke (adjusted OR 3.29; 95% CI 1.06−10.27), COPD (adjusted OR 4.82; 95% CI 1.53−15.16), and no ICD status (adjusted OR 2.68; 95% CI 1.36−5.26) were independently associated with CR non-enrollment. The main reasons for not being enrolled in CR were no medical referral (31%), concomitant medical problems (28%), patient refusal (11%), and geographical distance to the hospital (9%). Despite the relatively high proportion (35%) of HFrEF patients who underwent CR, the enrollment rate can be further improved. Innovative multi-level strategies addressing physicians’ awareness, patients’ comorbidities, and geographical issues should be pursued.

Safety and feasibility of a telemonitoring-guided exercise program in patients receiving cardiac resynchronization therapy

BACKGROUND

Telerehabilitation is an alternative clinic-based rehabilitation. A remote monitoring (RM) system attached to a cardiac rhythm device can collect physiological data and the device function. This study aimed to evaluate the safety and feasibility of telerehabilitation supervised by an RM in patients receiving cardiac resynchronization therapy (CRT).

METHODS

A single group pre-post exercise program was implemented for 3 months in 18 CRT recipients. The exercise regimen consisted of walking a prescribed number of steps based on a 6-min walk distance (6MWD) achieved at baseline. The patients were asked to exercise 3 to 5 times per week for up to 30 min per session, wearing an accelerometer to document the number of steps taken. The safety was assessed by the heart failure hospitalizations and all-cause death. The feasibility was measured by the improvement in the quality of life (QOL) using the EuroQol 5 dimensions, and daily active time measured by the CRT, 6MWD, B-type natriuretic peptide (BNP) level, and left ventricular ejection fraction (LVEF).

RESULTS

No patients had heart failure hospitalizations or died. No patients had any ventricular tachyarrhythmias. One patient needed to suspend the exercise due to signs of exacerbated heart failure by the RM. Compared to baseline, there were significant improvements in the QOL (-0.037, p < .05), active time (1.12%/day, p < .05), and 6MWD (11 m, p < .001), but not the BNP (-32.4 pg/ml, p = .07) or LVEF (0.28%, p = .55).

CONCLUSIONS

Three months of RM-guided walking exercise in patients with CRT significantly increased the QOL, active time, and exercise capacity without any adverse effects.
