Telenursing-based interventions, including patient education, remote monitoring, and post-discharge follow-up, may improve recovery; however, their effectiveness in this population has not been comprehensively synthesized.<br> <span style="color:#2980b9;"><b>Objective:</b></span> This systematic review aimed to evaluate the effectiveness of telenursing-based interventions on health outcomes following cardiovascular surgeries in adult patients.<br> <span style="color:#2980b9;"><b>Methods:</b></span> A comprehensive literature search was conducted in PubMed, Scopus, Web of Science, SID, MagIran, and Google Scholar from inception to June 28, 2026. We included Interventional studies investigating telenursing-based interventions in patients after cardiac surgery and assessing at least one health-related outcome. Bias risk evaluated using the Cochrane Risk of Bias 2 (RoB 2) tool. A narrative synthesis was performed due to substantial heterogeneity among the included studies.<br> <span style="color:#2980b9;"><b>Results:</b></span> Of the 535 records identified, 11 studies involving 3,262 participants met the inclusion criteria. &nbsp;<span lang="EN-GB">O</span>utcomes included quality of life, psychological outcomes, self-care behaviors, physical functioning, pain, hospital readmission, and healthcare utilization. Most studies reported favorable effects of telenursing interventions, particularly on quality of life, psychological outcomes, self-care, physical functioning, and reduction of hospital readmissions. Two studies were judged to have a high risk of bias, whereas nine studies raised some concerns regarding methodological quality.<br> <span style="color:#2980b9;"><b>Conclusion:</b></span> Telenursing-based interventions may complement post-cardiac surgery care by improving patient-centered outcomes and reducing healthcare utilization. However, methodological limitations and heterogeneity warrant further high-quality studies to confirm these findings and identify optimal implementation strategies.</span></span></span><br> &nbsp;</div> Telenursing, Nursing Care, Cardiac Surgical Procedures, Health Outcomes 114 120 http://nmcjournal.zums.ac.ir/browse.php?a_code=A-10-1053-3&slc_lang=en&sid=1 Zahra Khezerlou zahrakhezerloo8@gmail.com 100319475328460015573 100319475328460015573 Yes Department of Medical Surgical Nursing, School of Nursing and Midwifery, Zanjan University of Medical Sciences, Zanjan, Iran Saba Kalantari Saba.kalantari99@gmail.com 100319475328460015574 100319475328460015574 No PhD student of Nursing, Nursing and Midwifery School, Zanjan University of Medical Sciences, Zanjan, Iran Mahtab Aligholipour aligholipourmahtab@gmail.com 100319475328460015575 100319475328460015575 No Department of Critical Care and Emergency Nursing, School of Nursing and Midwifery, Zanjan University of Medical Sciences, Zanjan, Iran Razie Alipour razie.alipour72@gmail.com 100319475328460015576 100319475328460015576 No PhD student of Nursing, Nursing and Midwifery School, Zanjan University of Medical Sciences, Zanjan, Iran Darya Esmaeilbeigi daryyaesmailebigy@gmail.com 100319475328460015577 100319475328460015577 No PhD student of Nursing, Nursing and Midwifery School, Zanjan University of Medical Sciences, Zanjan, Iran Maryam mohammadi Mmohammadi@zums.ac.ir 100319475328460015578 100319475328460015578 No PhD Candidate in Nursing, Nursing and Midwifery School, Zanjan University of Medical Sciences, Zanjan, Iran Kazem Hajimohammadi kazemhajimohamadi@gmail.com 100319475328460015579 100319475328460015579 No Sygeplejerske (Registered Nurse, Birkevang Plejecenter, Herlufmagle, Danmark
