Abstract：Objective To explore the clinical significance of threadmill exercise test induced ST segment elevation to diagnose coronary heart disease. Methods: Compared the coronary artery contrast results of patients in ST segment elevation group and ST segment lower group in threadmill exercise test. Results: The positive rate，level of angiostenosis and involvement branch number of coronary artery contrast results of patients in ST segment elevation group and ST segment lower group were different significantly（P <0.05）. Conclusion: Threadmill exercise test induced ST segment elevation was the symbol of cardiac muscle local serious ischemic injury caused by coronary artery severe stricture or spasm，and it was the important index of diagnosing coronary heart disease .
