Does SYNTAX score II predict poor myocardial perfusion in XXXX ?

BACKGROUND: SYNTAX score II (SS-II) has been demonstrated to predict long-term outcomes in unprotected left main or multiple vessels in @entity1 with @entity453 . But its prognostic value for @entity1 with @entity583 ( @entity583 ) remains unknown. The poor myocardial perfusion (myocardial blush grade, @entity7584 0/1) after primary percutaneous coronary intervention (PPCI) has a negative prognostic value in @entity1 with @entity583 . We aimed to assess SS-II and its possible relationships with @entity7584 0/1 in @entity1 with @entity583 treated with PPCI. METHODS: The study included 477 @entity1 with @entity583 who underwent PPCI between October 2010 and May 2014. The SS-II and @entity7584 were determined in all @entity1 . @entity7584 were divided into @entity7584 0/1 (poor myocardial perfusion) and @entity7584 2/3 (normal myocardial perfusion). @entity1 were divided into 3 tertiles: SS-II low ( <= 20), SS-II intermediate (20-26) and SS-II high (>=  26). RESULTS: Compared with the SS-II intermediate and SS-II low tertiles, the SS-II high tertile had more @entity7584 0/1 (46.1%, 32.1% and 21.8%, p<0.001, respectively). On multivariate logistic regression analysis, SS-II was an independent predictor of @entity7584 0/1 (Hazard ratio [HR]: 1.084, 95% CI: 1.050 to 1.119; p<0.001). Receiver operating characteristic (ROC) analysis identified SS-II > 24 as the best cut-off value predicting @entity7584 0/1 (sensitivity of 66%, specificity of 54%). CONCLUSIONS: High SS-II is an independent predictor of @entity7584 0/1 in @entity1 with @entity583 undergoing PPCI.
