Abstract:

BACKGROUND: With the development with sports research, the effect of sports on heart has aroused increasing attention. 
OBJECTIVE: To systematic review myocardial stunning studies process, mechanism, and the relationship between exercise and myocardial stunning.
METHODS: This study was retrieved by the first author with the key words of “myocardial stunning, exercises, ischemia-reperfusion” in both English and Chinese (1980-01/2010-01) from PubMed databaseand Vip database. Totally 83 documents were initially searched by computer. A total of 36 articles were selected according to inclusive and exclusive criteria, and the papers were summarized from the aspects of definition, characteristics, classification, mechanism and effect on myocardial stunning.
RESULTS AND CONCLUSION: Myocardial stunning was clinical studied more and more deeply, the definition, characteristics and categories of myocardial stunning are clarified, and also began to explore the myocardial stunning possible mechanism in molecular biology level. However, long duration, vigorous exercise caused exercise athletes perfusion defect leading to reduced cardiac function and myocardial injury, the exercise myocardial stunning phenomenon should be possible.
