The National Registry of Supported Angioplasty was formed in 1988 to collect data on patients undergoing supported angioplasty. The Registry was expanded to include patients also undergoing standby supported angioplasty. In 3 years the Registry collected data on 801 patients undergoing supported or standby supported angioplasty. The data indicate that in patients with low ejection fractions and/or > or = 50% of jeopardized myocardium at risk can have an interventional procedure performed with a 6.9% risk of mortality with prophylactic or standby support, but patients with < or = 20% ejection fraction do better with prophylactic support. In addition, patients with LMCA stenosis and age > or = 70 years are at higher risk. The Registry also demonstrates good long-term results for patients who have undergone the procedure.
国家支持性血管成形术注册中心成立于1988年，旨在收集接受支持性血管成形术患者的数据。该注册中心后来扩大到也包括接受备用支持性血管成形术的患者。在3年时间里，该注册中心收集了801例接受支持性或备用支持性血管成形术患者的数据。数据表明，射血分数低和/或有≥50%的濒危心肌处于危险中的患者，在预防性或备用支持下进行介入手术时，死亡率风险为6.9%，但射血分数≤20%的患者接受预防性支持效果更好。此外，左主干狭窄且年龄≥70岁的患者风险更高。该注册中心还显示，接受该手术的患者有良好的长期效果。
