报告简介(Abstract):

Coronary heart disease is a global epidemic that led to roughly 1/3 of deaths worldwide. Extensive clinical evidence suggests that a preventive screening of coronary heart disease at an earlier stage can greatly reduce mortality rate. The most popular preventive practice is the stress ECG test which requires large amount of clinician's participation and practically infeasible for senior subjects or subjects with disability. There are also other problems such as risk of heart failure and time consuming. To deal with this problem, we present an echo-cardiology based screening method that only use clinical records and myocardial movements as diagnosis features. The entire practice only need 30 second to complete.  Based on a clinical trail that is conducted in Beijing hospital,  the prediction accuracy of our method on testing data can reach 93% accuracy. Our results lay a foundation for the deployment of echo-based screening tools for global

improvements of cardio health.
