Effectiveness of Myocardial Contrast Echocardiography Quantitative Analysis during Adenosine Stress versus Visual Analysis before Percutaneous Therapy in Acute Coronary Pain: A Coronary Artery TIMI Grading Comparing Study

Table 5

Accuracy, sensitivity, and specificity of abnormal in MCE Visual Interpretation at rest and stress with different TIMI flow grades as abnormal (%).

TIMI flow grades	Accuracy	Sensitivity	Specificity
Grade <1:
rest	72.0	85.4	70.7
stress	65.6	97.9	62.6
Grade <2:
rest	77.7	76.8	78.1
stress	76.7	93.6	71.9
Grade <3:
rest	73.1	58.2	84.2
stress	80.4	76.6	83.3

TIMI: thrombolysis in myocardial infarction trial.
TIMI grade <1, grade 0 was abnormal, grades 1, 2, and 3 were normal for TIMI grade. TIMI grade <2, grades 0 and 1 were abnormal, grades 2 and 3 were normal for TIMI grade. TIMI Grade <3, grades 0, 1, and 2 were abnormal, grade 3 was normal for TIMI grade.
