经皮冠状动脉介入治疗术后血管痉挛性心绞痛的病因及诊断方法的研究进展

Research progress in etiology and diagnosis of vasospastic angina after percutaneous coronary intervention

成功行经皮冠状动脉介入治疗(PCI)术的患者在中短期随访中,有20%~35%的患者出现术后复发性心绞痛。既往行PCI术的患者在重复血管造影无明显心外膜病变新证据时,血管痉挛性心绞痛(VSA)是复发性心绞痛的常见原因,但易被误诊或漏诊。本文结合近年来国内外对于冠状动脉痉挛(CAS)及PCI术后VSA的相关研究,总结并归纳了PCI术后VSA的病因及诊断方法,以提高临床医师对该病的认识。

Recurrence of angina after a successful percutaneous coronary intervention(PCI) may affect about 20%-35% of patients during short-medium-term follow-up. For patients previously undergoing PCI with repeat coronary angiography indicating no new evidence of significant epicardial disease, vasospastic angina(VSA) is a common cause of recurrent angina. However, it is prone to be misdiagnosed or miss-diagnosed. In combination with the relevant studies on coronary artery spasm(CAS) and VAS after PCI at home and abroad in the recent few years, this paper summarizes and concludes the etiology and diagnostic methods of VSA after PCI to help clinicians gain a better understanding of the disease.
