Data are presented as mean ± SD, median (25th-75th percentile), or frequency (%). CRP: C-reactive protein; eGFR: estimated glomerular filtration rate; NT-proBNP: N-terminal pro-brain natriuretic peptide; TIMI: Thrombolysis In Myocardial Infarction; WMSI: Wall Motion Score Index.
Statistical analysis
Normality of the data was tested using the Shapiro-Wilk test, and homogeneity of variance was tested with Levene’s test. All continuous variables are presented as mean±standard deviation or median [25th–75th percentile] according to their normal or non-normal distribution. Categorical variables are presented as counts and percentages. Univariate regression analysis was used to identify variables associated with reference vessel CFVR at the end of the PPCI procedure (pinclusion < 0.1), with candidate variables including all
