Objectives　To explore the effect of case analysis method in clinical nursing practice teaching of cardiology diseases. Methods　48 nursing undergraduates in cardiology department from July 2015 to May 2017 were selected into experimental group and 50 nursing undergraduates from July 2013 to June 2015 in cardiology department were retrospectively divided into control group. The control group adopted small lectures to explain the nursing assessment

diagnosis and nursing measures to the students. In experimental group

case analysis method was applied into nursing practice teaching

which concluded guid-ing group students to choose common kinds of typical cases firstly

collecting the patient's information

reviewing nursing assessment

diagnosis and intervention of the selected disease

and finally comparing cases with theoretical knowledge. After that

group students should apply case analysis method to clinical nursing practice under the guidance of teachers. Finally

academic performance

overall nursing assessment

and acceptance of the case analysis method in the above two groups were compared. Results　The results of experimental group in academic performance [(81.70±3.22) vs. (75.63±3.01)] and in overall nursing exam-ination [(91.93±3.07) vs. (84.27±3.08)] were significantly superior to control group. Meanwhile

the exper-imental group students showed higher acceptance of case analysis method. Conclusion　Case analysis method can help nursing undergraduates to combine theoretical knowledge and clinical practice better

make deeper understanding of theoretical knowledge

apply it in clinical practice neatly

and improve students' ability of critical thinking.
