BACKGROUND: Patients after coronary artery bypass grafting often face suboptimal recovery, including pain, reduced quality of life, and haemodynamic instability, worsened by limited self-care knowledge and inadequate post-discharge support. Nurse-led smartphone-based interventions may offer a scalable solution for resource-limited settings. OBJECTIVE: To evaluate the effects of a nurse-led, smartphone-based educational and follow-up intervention on pain, quality of life, and haemodynamic stability in patients undergoing elective coronary artery bypass grafting. DESIGN: Single-blind, randomized controlled trial. SETTINGS: A tertiary cardiac surgery center in Shiraz, Iran, from July 2024 to April 2025. PARTICIPANTS: Eighty-four adults undergoing elective coronary artery bypass grafting, randomized (1:1) to intervention or control groups, with 80 completing the study (40 per group). METHODS: The intervention group received a three-phase programme: (1) pre-operative education via videos, messages, and a face-to-face session; (2) in-hospital education and daily symptom monitoring for pain and self-care; (3) 30-day post-discharge follow-up with weekly nurse-led calls and real-time messaging. Controls received standard care with one handout. Outcomes included pain (visual analog scale), quality of life (SF-36 Health Survey), and hemodynamic indices (blood pressure, heart rate). Pain and haemodynamic indices were assessed at baseline, three times daily for four days in the gener...
