Coronary sinus flow results stratified by clinical group.
| | | Healthy volunteers (n = 10) | MI without MVO (n = 10) | MI with MVO (n = 10) | value |
| | CS flow (mL/min) | 123.8 (±48.4) | 85.7 (±30.5) | 67.9 (±29.2) | 0.007 | | CS flow (mL/min/g) | 1.48 (±0.47) | 0.81 (±0.35) | 0.51 (±0.19) | <0.001 | | Peak CS velocity (cm/s) | 22.7 (±6.3) | 13.1 (±5.8) | 15.8 (±5.1) | 0.003 | | MyoR (mmHg·min·mL−1) | 0.79 (±0.35) | 1.10 (±0.50) | 1.50 (±0.69) | 0.02 |

CS = coronary sinus; MI = myocardial infarction; MVO = microvascular obstruction; MyoR = myocardial resistance.
