Angiographic, Coronary Hemodynamic, and PET Data
| Parameter | Value |
|---|---|
| DS infarct-related artery (%) | 54 ± 25 |
| FFR infarct-related artery | 0.75 ± 0.16 |
| FFR reference coronary artery | 0.97 ± 0.02* |
| hRPP during angiography (bpm·mm Hg) | 7,849 ± 1,587 |
| MBF infarcted area (mL/min/mL) | |
| At baseline | 0.73 ± 0.20 |
| At hyperemia | 2.21 ± 1.02 |
| MBF reference area (mL/min/mL) | |
| At baseline | 0.89 ± 0.22* |
| At hyperemia | 2.92 ± 1.11* |
| RFR | 0.74 ± 0.18 |
| hRPP during PET study (bpm·mm Hg) | 8,479 ± 1,805 |
↵* P < 0.0001 for reference vs. infarcted area.
DS = diameter stenosis; hRPP = hyperemic rate–pressure product; MBF = myocardial blood flow.
