摘要：

BACKGROUND Patients with vasospastic angina(VSA)sometimes experience prolonged chest symptoms.The clinical characteristics of these patients have not been clarified.AIM To investigate the clinical characteristics of prolonged VSA patients.METHODS This study included 167 patients with VSA diagnosed by spasm provocation tests(SPTs)using acetylcholine,which recorded the frequencies of positive reactions to a low dose of acetylcholine(L-ACh),total occlusion due to spasm(TOC),focal spasm,and the unavoidable use of nitroglycerin(unavoidable-NTG)during SPTs.The patients underwent a medical interview that investigated the maximum duration and frequency of chest symptoms as well as the frequencies of variant angina and other serious symptoms.The patients were divided into two groups based on the maximal duration:The short-duration group(<15 min;n=114)and the long-duration group(≥15 min;n=53).They were also divided into two groups based on the frequency of chest symptoms:The low-frequency group(<4/mo;n=88)and the high-frequency group(≥4/mo;n=79).RESULTS The long-duration group showed higher frequencies of other serious symptoms(P<0.001)and variant angina(P<0.05)as well as higher frequencies of spasm induction by L-ACh(P<0.05),TOC(P<0.05),focal spasm(P<0.01),and unavoidable-NTG(P<0.01)than the short-duration group.These parameters did not differ significantly between the low-frequency and high-frequency groups.CONCLUSION These findings suggest that patients with VSA who experience prolonged chest symptoms may have more severe characteristics of VSA.
