Abstract
<p><span style="font-size:11pt"><span style="font-family:Aptos,sans-serif">Introduction</span></span></p> <p><span style="font-size:11pt"><span style="font-family:Aptos,sans-serif">Remote monitoring (RM) of cardiac implantable electronic devices (CIEDs) has emerged as a promising strategy to improve clinical outcomes in patients with heart failure (HF), primarily by enabling early detection of physiological deterioration and arrhythmic events. However, the magnitude of its impact on HF hospitalizations and cardiovascular (CV) mortality remains variable across individual randomized trials. This meta-analysis aimed to evaluate the effect of RM compared with usual care (UC) on HF-related and mortality outcomes in patients with CIEDs.</span></span></p> <p><span style="font-size:11pt"><span style="font-family:Aptos,sans-serif">Methods</span></span></p> <p><span style="font-size:11pt"><span style="font-family:Aptos,sans-serif">A systematic search of PubMed, Embase, and the Cochrane Library was conducted to identify randomized controlled trials (RCT) published between January 2019 and June 2025. Eligible studies compared RM with UC in adult CIED recipients and reported HF hospitalization or CV mortality data. Extracted variables included sample size, baseline characteristics, follow-up duration, and event counts in RM and UC groups. A fixed-effects Mantel–Haenszel model was used given the absence of statistical heterogeneity across studies.</span></span></p> <p><span style="font-size:11pt"><span style="font-family:Aptos,sans-serif">Results</span></span></p> <p><span style="font-size:11pt"><span style="font-family:Aptos,sans-serif">A total of 4 RCT comprising 2.383 patients were included (1.268 assigned to RM and 1.115 to UC). Across trials, patients had advanced HF with mean left ventricular ejection fraction between 26.5% and 30%, predominantly male (79–90%), and with follow-up ranging from 1 to 24 months. RM was associated with a statistically significant reduction in HF hospitalizations compared with UC (odds ratio [OR] 0.77; 95% confidence interval [CI] 0.63–0.94; p = 0.009), with no evidence of heterogeneity (I² = 0%). Overall, 249 HF hospitalizations occurred in the RM group versus 298 in the UC group. In contrast, RM did not reduce cardiovascular mortality, with a pooled odds ratio of 0.92 (95% CI 0.58–1.44; p=0.71) and no heterogeneity across studies (I²=0%).</span></span></p> <p><span style="font-size:11pt"><span style="font-family:Aptos,sans-serif">Conclusion</span></span></p> <p><span style="font-size:11.0pt"><span style="font-family:"Aptos",sans-serif">In summary, RM in patients with CIEDs significantly reduces HF hospitalizations but does not confer a measurable reduction in short-term CV mortality. These findings indicate that RM primarily mitigates HF decompensation rather than altering mortality trajectories, underscoring the need for longer follow-up and more standardized RM intervention pathways</span></span></p>
