TIMI: thrombolysis in myocardial infarction trial; PCI: percutaneous coronary intervention.
MCE visual interpretation at rest and TIMI flow grade correlated positively, rs  =  0.691, 𝑃 < . 0 0 1 .
PCI: percutaneous coronary intervention; TIMI: thrombolysis in myocardial infarction trial.
Grades 0, 1, and 2 were abnormal, grade 3 was normal for TIMI grade. MCE Visual Interpretation 0 and 0.5 were abnormal, and 1 was normal for MCE Visual Interpretation.
On diagnosing myocardial perfusion abnormality TIMI flow grade and MCE Visual Interpretation at rest had a high degree of agreement, Kappa = .687, 𝑃 < . 0 0 1 .
