Inclusion criteria
Inclusion criteria: Patients who underwent stress dynamic CTP for the assessment of CAD between July 2013 and November 2017.
Exclusion criteria
Exclusion criteria: (1) acute myocardial infarction (<30 days from the onset), (2) cardiomyopathy, (3) left ventricular ejection fraction <20%, (4) atrial fibrillation, (5) an atrioventricular block greater than the first degree, (6) complete left bundle branch block, (7) history of percutaneous coronary intervention or coronary artery bypass grafting, (8) poor cardiac MR image quality, and (9) an inappropriate CTP dataset such as that with insufficient image quality, misaligned scan coverage, and delayed data acquisition of dynamic CTP causing a shorter baseline (before upslope) of the TAC in the ascending aorta.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The global CTMBFs with 2RR, 3RR, and 4RR sampling are compared with that with 1RR sampling as a reference, using the equivalence test with Bonferroni correction. | — |
Secondary
| Measure | Time frame |
|---|---|
| The Pearson rank correlation test is used to assess the relationship between the global CTMBF with 1RR sampling and that with 2RR, 3RR, or 4RR sampling. The equivalence test with Bonferroni correction is used to compare segmental CT-MBFs with 2RR, 3RR, and 4RR sampling to that with 1RR sampling for normal and abnormal myocardial segments that were assessed with cardiac MR. The areas under the receiver operating characteristic curve of segmental CT-MBF with 2RR, 3RR, and 4RR sampling are compared with that with 1RR sampling. | — |
