This narrative review aims to evaluate the current evidence on the use of cardiac telerehabilitation (CTR) in patients after myocardial infarction, focusing on the effectiveness of e-learning platforms and remote monitoring for addressing cardiovascular risk factors, improving physical fitness, and enhancing patient adherence. The review also explores the limitations and gaps in the literature, highlighting the need for future research to optimize CTR approaches. A comprehensive literature search was conducted using PubMed and Scopus, focusing on specific keywords. The search yielded fifteen randomized controlled trials. Data from these studies were analyzed to evaluate the methodology, interventions, patient characteristics, and outcomes related to the use of CTR in managing cardiovascular risk factors and improving physical fitness. The included studies demonstrated that CTR interventions, delivered via online platforms, phone calls, and smart devices, were effective in improving cardiovascular risk factors, physical activity levels, and overall patient satisfaction. CTR appears to be associated with improvements in exercise tolerance, VO₂ max, body composition, and adherence. While the outcomes were promising, there is still limited evidence regarding the long-term impact of CTR on cardiovascular risk factors and lifestyle interventions, particularly in non-exercise components like dietary management and psychological support. Cardiac telerehabilitation presents a feasible and effective alternative to traditional in-hospital rehabilitation programs for patients recovering from myocardial infarction. The integration of e-learning platforms and smart devices enhances patient adherence, improves cardiovascular risk factors, and increases access to rehabilitation services, particularly for those who face barriers to traditional care. However, further large-scale studies are needed to establish standardized protocols and best practices for CTR. Additionally, future research should address disparities in access to digital health technologies, especially among rural and underserved populations, to ensure equitable access to these innovative approaches.

Background/Objectives: Cardiac rehabilitation (CR) is known to improve clinical outcomes in cardiovascular disease, yet its benefits in patients with implantable cardioverter-defibrillators (ICD) are not well established. This meta-analysis evaluated the impact of CR on functional capacity and safety in ICD recipients. Methods: A systematic search of PubMed, Scopus, and Cochrane Library was performed to identify randomized controlled trials (RCT) involving adults who underwent ICD implantation and were assigned to either CR or standard care. The primary outcome was the change in peak oxygen uptake (peak VO₂) from the baseline to the final follow-up. Random-effects models were applied, and subgroup analyses were conducted based on follow-up duration, supervision type, baseline peak VO₂, and ischemic vs. non-ischemic etiology. Results: Seven RCTs involving 1461 participants (784 CR; 677 control) met the inclusion criteria. CR was associated with a significant improvement peak VO₂ compared with usual care, expressed as the mean difference (MD) in change from the baseline to the last follow-up (MD 2 mL·kg⁻¹·min⁻¹; 95% CI 1.02–2.81; I² = 65.7%), with consistent effects across all subgroups. Quality of life improved in the CR group (MD 6.46; 95% CI 2.25–10.67; I² = 0%). A non-significant trend toward increased 6MWT distance was observed. CR did not increase adverse events, including ICD shocks, hospitalizations, or cardiac deaths. Conclusions: CR safely enhances exercise capacity and quality of life in ICD recipients without increasing arrhythmic events or mortality. Larger standardized trials are warranted to optimize CR delivery in this population.
