Hemoglobin (Hb) loss and tachycardia in patients with or without transient or persistent cardiac troponin isoform I (cTnI) elevations
| Parameter | cTnI− (n = 51) | cTnI+ (n = 16) | P (cTnI− vs. cTnI+) |
|---|---|---|---|
| Hb (g/dl): | |||
| T0 | 13.0 (11.8–13.9) | 13.3 (12.4–14.7) | 0.255 |
| T1 | 11.6 (10.5–12.3) | 10.4 (9.80–11.8) | 0.080 |
| P (T0 – T1) | <0.0001 | 0.001 | |
| Heart rate (bpm): | |||
| T0 | 76 (70–81) | 76 (69–82) | 0.994 |
| T1 | 85 (75–89) | 87 (79–100) | 0.168 |
| P (T0 – T1) | <0.01 | <0.01 |
cTnI− or cTnI+ denotes the absence or presence of cTnI elevations. Data were analyzed by two-tailed Mann-Whitney test or Wilcoxon matched-paired t test as appropriate. Hb, hemoglobin.
