The Predictive Value of Baseline Target Lesion SYNTAX Score for No-Reflow during Urgent Percutaneous Coronary Intervention in Acute Myocardial Infarction

Table 3

Univariable and multivariable analysis of the association between TL-SS and no-reflow.

TL-SS level, categorical/continuous	Number of patients with no-reflow (%)	Unadjusted OR (95% CI)	Unadjusted value	Adjusted OR (95% CI) (model 1)	Adjusted p value (model 1)	Adjusted OR (95% CI) (model 2)	Adjusted value (model 2)
Low tertile (n = 155)	1 (0.6%)	Reference	—	Reference	—	Reference	—
Median tertile (n = 207)	20 (9.7%)	16.47 (2.64–147.76)	0.007	8.92 (1.08–73.55)	0.042	8.91 (1.11–71.78)	0.040
High tertile (n = 166)	32 (19.3%)	36.78 (4.96–272.77)	<0.001	15.13 (1.92–119.09)	0.010	14.81 (1.91–114.78)	0.010
Per 1 score	—	1.14 (1.09–1.19)	<0.001	1.08 (1.03–1.14)	0.001	1.08 (1.03–1.13)	0.001

Note. Covariates of model 1: TL-SS, age, EF, STEMI, LCX location, and reference vessel diameter. Covariates of model 2: TL-SS, age, EF, STEMI, LCX location, reference vessel diameter, balloon predilation, and thrombus aspiration. CI, confidence interval; EF, ejection fraction; LCX, left circumflex coronary artery; OR, odds ratio; PCI, percutaneous coronary intervention; STEMI, ST-segment elevation myocardial infarction; TL-SS, target lesion SYNTAX score.
