  1. Note—Reported values are median ± interquartile range (IQR). P-values were computed using multivariable linear regression models with age, sex, and heart rate as covariates. Bold text represents a significant P-value. ΔMI is the expected difference in the LV flow parameter due to the anterior AMI. 95% CI is the 95% confidence interval for ΔMI
