  "abstract": "Background: Smart wrist-worn devices are increasingly used by patients after percutaneous coronary intervention (PCI) to monitor heart rate, rhythm-related alerts, sleep, activity, and other health-related data. However, limited qualitative evidence exists on how post-PCI patients interpret and respond to such information in daily life.\n\nObjective: This study aimed to explore how patients with coronary heart disease after PCI understand, evaluate, and respond to heart rate, heart rhythm, and health-related information generated by smart wrist-worn devices.\n\nMethods: A qualitative descriptive design was adopted. From January to May 2026, purposive sampling was used to recruit 23 post-PCI patients who had used smartwatches or smart bands in daily life. Semi-structured interviews were conducted, audio-recorded, transcribed verbatim, and analyzed using thematic analysis. Data collection and analysis were conducted concurrently until data saturation was achieved.\n\nResults: Four themes were developed: (1) cardiac status became continuously datafied; (2) calibrating risk between alerts and sensations; (3) device information awaited medical interpretation; and (4) from self-management to disease burden. Patients did not simply accept or reject device-generated data. Instead, they interpreted alerts by comparing them with bodily sensations, previous cardiac events, stent implantation experiences, follow-up results, and healthcare professionals' explanations. Device information could enhance awareness of medication use, follow-up, and lifestyle management. However, when alerts lacked medical interpretation or follow-up response, they also increased uncertainty, worry, repeated self-monitoring, and perceived disease burden.\n\nConclusions: Smart wrist-worn devices may support daily observation and clinician–patient communication in post-PCI management, but they should not be regarded as substitutes for clinical examinations or professional judgment. Clearer interpretive boundaries, stratified guidance, and follow-up response pathways are needed to help patients appropriately understand and act on device-generated information.",
