There are a large population of coronary heart disease patients in China, which needs more attention to optimize the secondary prevention and improve the prognosis. Secondary prevention has been showing the effects of improving symptoms, preventing disease progression, improving prognosis, and reducing mortality in patients received coronary artery bypass grafting (CABG) surgery. In this study, we are trying to evaluate the effectiveness of artificial intelligence (AI) assisted follow-up strategy on secondary prevention for patients received CABG surgery. And we are trying to find out whether there is difference in secondary prevention of coronary heart disease between urban and rural patients.
The present study is trying to find out whether artificial intelligence assisted follow-up strategy will improve secondary prevention in CABG patients. In addition, we will test whether rural patients may have more benefits under the new follow-up strategy based on the artificial intelligence device compared with urban patients.
