Background: Relying on existing data,it is unknown whether coronary spasticity in vasospastic patients disappears or not. We evaluated coronary spasticity in vasospastic patients by repeated coronary angiography. Subjects and Method: The subjects consisted of 19 patients diagnosed as having vasospastic angina by coronary angiography and who underwent repeated coronary angiography. We evaluated coronary spasticity by ergonovine or acetylcholine coronary provocative tests.

 Result: All of the 19 patients showed positive findings in the final coronary provocative test. 23 of 34 lesions presented the same positive findings in all provocative tests,but 10 lesions showed new positive findings.

 Conclusion: Coronary spasticity in vasospastic patients is shown not to disappear in provocative coronary angiography,so administration of anti-spastic agents,mainly Ca-antagonists,is necessary to treat semi-permanent vasospastic patients identified by provocative coronary angiography,inspite of disease activity. However,further studies are necessary.
