Brief Summary

This study aims to evaluate the effect of an AI-assisted "Smart family doctor" digital health management tool on improving the control rates of hypertension, diabetes, and dyslipidemia in post-CABG (coronary artery bypass grafting) patients or post-PCI (percutaneous coronary intervention) patients. A randomized controlled trial design will be used, involving approximately 5-10 hospitals and 536 participants. Eligible participants are adults aged 18 or older, post-CABG or post-PCI patients with hypertension, diabetes, and dyslipidemia.

Study Arms (2)

"Smart family doctor" assisted management plus health managers

EXPERIMENTAL

"Smart family doctor", an AI-assisted applications with personalized interactions and 3-hour health management guidance from a health manager once a week.

Behavioral: Smart family doctorBehavioral: Health manager

Usual care: health managers

PLACEBO COMPARATOR

3-hour health management guidance from a health manager once a week.

Behavioral: Health manager

Interventions

Health managerBEHAVIORAL

Participants will received 3-hour health management guidance from a health manager once a week, including guidance on healthy lifestyle, medication treatment, and rehabilitation advice. The research team will provide participants with one smart band, requiring them to wear the band daily to collect health data during the 6-month study period.

"Smart family doctor" assisted management plus health managersUsual care: health managers

Based on health managers, participants were additionally provided "Smart family doctor", which is an AI-assisted applications with personalized interactions. The content includes, but is not limited to: (1) General educational content, covering basic health knowledge on diseases, risk factors, and treatment methods; (2) Targeted health information, such as more specific guidance on blood pressure and blood sugar control, medication adherence, exercise, and smoking cessation; (3) Personalized disease management guidance, providing tailored reminders for patients regarding medication, diet, exercise, and medical visits. Patients can also directly report their latest self-measured blood pressure, blood lipid, blood sugar levels, and medication adherence to receive treatment and medication guidance from the 'Smart family doctor'.

Intervention Model
PARALLEL
Model Details: The intervention in this study is the implementation of the 'Smart family doctor' system, a digital health management tool designed to support secondary prevention in post-CABG patients or post-PCI patients. This system leverages knowledge from coronary artery disease (CAD) secondary prevention guidelines, expert consensus, and a knowledge base addressing common post-CABG issues. It is powered by a large-scale, medical knowledge-enhanced conversational model, enabling personalized interactions with patients to guide their recovery and lifestyle management following surgery.
