In this context, home-based cardiac rehabilitation (HBCR) has emerged as a promising alternative. However, maintaining adherence and providing continuous supervision in remote settings remain a major challenge. Smartwatch-based interventions may offer a novel solution to support and monitor patients in HBCR programs, yet robust clinical evidence is still limited.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n This study was designed to investigate the effectiveness of a smartwatch-facilitated HCBR model in improving exercise adherence and health-related outcomes in patients with coronary heart disease (CHD), aiming to improve adherence and other outcomes related to the secondary prevention of cardiovascular disease.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We conducted a prospective, single-center, randomized, parallel-controlled, non-blinded trial. Eligible participants were adults (\u226518 years) with a confirmed diagnosis of CHD, recruited from a tertiary hospital in Jilin Province, China. Participants were randomly assigned in a 1:1 ratio to either the intervention group (smartwatch-facilitated HBCR) or the control group (standard HBCR) for a duration of 3 months. The intervention group received a comprehensive program delivered via a smartwatch, including real-time feedback, remote supervision, physical activity monitoring, and educational content. The control group received conventional HBCR without technological assistance. The primary outcome was adherence to the HBCR program, assessed using the Home-Based Cardiac Rehabilitation Exercise Adherence Scale. Secondary outcomes included cardiopulmonary function (peak VO\u2082 measured via cardiopulmonary exercise testing), anxiety (Generalized Anxiety Disorder-7), depression (Patient Health Questionnaire-9), and health-related quality of life (36-Item Short Form Survey, SF-36), evaluated at baseline and at 3 months.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Between January 1 and December 30, 2023, a total of 62 patients (mean [SD] age 59.93 [10.06] years; 40.4% women [25\/62]) were enrolled and randomized to the intervention group (n=32) or control group (n=30). Baseline characteristics were well balanced between the groups. At 3 months, participants in the smartwatch group demonstrated significantly higher adherence scores compared to the control group (\n P<\/jats:italic>\n <.01). Additionally, the smartwatch group showed significant improvements in peak VO\u2082 (\n P<\/jats:italic>\n <.01), anxiety (GAD-7,\n P<\/jats:italic>\n <.01), depression (PHQ-9,\n P<\/jats:italic>\n <.01), and selected domains of SF-36 (\n P<\/jats:italic>\n <.05). No serious adverse events related to the intervention were reported, and user engagement with the smartwatch platform was high throughout the study period.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n This study demonstrates that a smartwatch-facilitated HBCR model is both feasible and effective in enhancing adherence and improving clinical outcomes among patients with CHD. These findings support the integration of wearable technology into routine HBCR and lay the groundwork for future large-scale, multicenter trials.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/70848","type":"journal-article","created":{"date-parts":[[2025,7,30]],"date-time":"2025-07-30T21:55:09Z","timestamp":1753912509000},"page":"e70848-e70848","source":"Crossref","is-referenced-by-count":16,"title":["Effectiveness of Smartwatch Device on Adherence to Home-Based Cardiac Rehabilitation in Patients With Coronary Heart Disease: Randomized Controlled Trial"],"prefix":"10.2196","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0356-0906","authenticated-orcid":false,"given":"Sisi","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2114-1059","authenticated-orcid":false,"given":"Yuehui","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-2654-5959","authenticated-orcid":false,"given":"Jiahui","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5387-5957","authenticated-orcid":false,"given":"Changsheng","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5550-499X","authenticated-orcid":false,"given":"Xiaoping","family":"Meng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2025,9,18]]},"reference":[{"issue":"8","key":"R1","doi-asserted-by":"publisher","first-page":"799","DOI":"10.1093\/eurheartj\/ehac064","article-title":"European Society of Cardiology: cardiovascular disease statistics 2021","volume":"43","author":"Timmis","journal-title":"Eur Heart J"},{"key":"R2","doi-asserted-by":"crossref","unstructured":"Tsao CW Aday AW Almarzooq ZI et al.
