The variables during the three balloon inflations in the patients in the myocardial ischaemia group
| Variable | Subgroup (n) | 1st BI | 2nd BI | 3rd BI | F value | p Value |
|---|---|---|---|---|---|---|
| Values are mean (SD). | ||||||
| *p<0.05 v first balloon inflation. | ||||||
| †The number of the patients with surface ST elevation was reduced owing to the fact that patients were excluded from the analysis of this variable when no surface ST elevation was present. | ||||||
| BI, balloon inflation; MAP, mean arterial pressure; RPP, rate–pressure product (heart rate × mean blood pressure). | ||||||
