Objective　To establish an index system for the construction of cardiovascular nursing discipline based on the internal and external integration model of organ system

and to provide reference for the construction of cardiovascular nursing discipline with patients as the center and circulatory system as the core. Methods　Based on the health science cluster system theory

embodying the integrated nursing concept and the characteristics of cardiovascular discipline

the content of the cardiovascular nursing discipline construction index system and the weight of each index were determined through literature review

semi-structured interview and expert consultation. SPSS 23.0 was used to statistically analyze the obtained consultation data. Results　The positive coefficient of the experts was 92.308%

the authority coefficient was 0.812

and the coordination coefficients of the first-

second- and third-level indicators were 0.412

0.421 and 0.347

respectively. The final indicator system consisted of 4 first-level indicators

17 second-level indicators and 66 third-level indicators. Conclusion　The index system of cardiovascular nursing discipline construction is scientific and reliable

which has certain guiding significance to the construction of cardiovascular nursing discipline and the cultivation of talents under the integrated medical model.
