Abstract: The goal of cardiovascular specialist training is higher than that of resident physician training. The doctors who complete the training should be able to improve their medical, teaching and scientific research ability significantly, and reach the level of attending physicians of cardiovascular specialists. How to improve the teaching ability of cardiovascular trainees is a difficult point in cardiovascular specialist training. The purpose of this project is to explore whether the implementation of case-based learning (CBL) led by cardiovascular trainees can improve the comprehensive ability. The special training students were randomly divided into two groups, adopting CBL teaching method and traditional teaching method respectively. After the course, the teaching effects were investigated by tests and questionnaires. The scores of clinical theory and case analysis in CBL teaching group were higher than those in the control group. By leading CBL teaching, the cardiology trainees have improved their teaching ability, organizational ability and discipline coordination. Compared with the traditional teaching method, CBL teaching method has better teaching effect and is conducive to the improvement of the comprehensive ability of cardiovascular training students

Key words: lead by specialized trainees, casebased learning, specialized in cardiovascular medicine
