- Data are expressed as mean ± SD or number (%)
- *P-values represent the difference between patients with and without MACE. **P < 0.05 vs. CSBF at rest
- ΔCSBF = CSBF during ATP infusion–CSBF at rest
- Coronary flow reserve = CSBF during ATP infusion / CSBF at rest × 100
- ATP adenosine triphosphate, CSBF coronary sinus blood flow, CFR coronary flow reserve, MACE major adverse cardiac events, SD standard deviation
