The present disclosure belongs to the technical field of biomedicine and, particularly, relates to a use of an MYOG gene as a target in the preparation of a drug for treating a cardiomyocyte apoptosis-associated cardiovascular disease (CVD). By constructing angiotensin II-induced human induced pluripotent stem cell-differentiated cardiomyocyte apoptosis models in vitro, the present disclosure reveals for the first time the role of the transcription factor MYOG in the inhibition of cardiomyocyte apoptosis and provides a theoretical and scientific basis for drug research and development of cardiomyocyte apoptosis-associated CVDs. MYOG gene becomes a new target for CVD drug research and development.
