摘      要：Background:Chronic total occlusion(CTO)is a critical and unique subgroup of coronary *** study aimed to investigate the correlation between the Selvester QRS score and late gadolinium enhancement cardiac magnetic resonance imaging(LGE-CMRI)in quantifying myocardial scarring to provide a simple and feasible method for treating ***:The medical records of 134 patients with absolute CTO who underwent coronary angiography between May 1,2014 and December 30,2017 were retrospectively *** patients were grouped according to the CTO location(right coronary artery[RCA]CTO,left artery descending[LAD]CTO,left circumflex[LCX]CTO,and multivessel CTO groups).The degree of myocardial scarring was determined according to the Selvester QRS score and using the *** patients were followed up for at least 12 ***:Among the 62 CTO patients,55 had occlusion of a single vessel and seven had occlusion of multiple vessels,of which 27(43.55%)were in the RCA CTO group,16(25.81%)in the LAD CTO group,12(19.35%)in the LCX CTO group,and 7(11.29%)in the multivessel CTO *** area under the receiver operating characteristic curve for the QRS score that was used to determine the degree of myocardial scarring was 0.806,with a sensitivity and specificity of 94.7%and 42.1%,*** Selvester QRS score and LGE-CMRI measures of scar size were correlated in the RCA CTO,LCX CTO,and multivessel CTO groups(r=0.466,0.593,and 0.775,respectively).Conclusion:The Selvester QRS score was feasible for detecting myocardial scarring in patients with CTO.
