Complication rates compared to cTnT and CK concentrations
| Normal cTnT | cTnT positive | CK | |||
|---|---|---|---|---|---|
| End point | ⩽0.01 μg/l (n = 338) | Tertile 1 ⩽0.26 μg/l (n = 159) | Tertile 2 ⩽1.1 μg/l (n = 156) | Tertile 3 >1.1 μg/l (n = 151) | ⩾400 IU/l (n = 250) |
| For the upper tertile of cTnT (>1.1 μg/l), the risk of LVF, death, and combined death/LVF was significantly greater than that of all the other troponin groups (p<0.003). | |||||
| Percentage figures of each group are shown in brackets. | |||||
| CK, creatine kinase, cTnT, cardiac troponin T; LVF, left ventricular failure. | |||||
| LVF | 33 (9.9) | 24 (15.1) | 29 (18.6) | 36 (23.8) | 61 (24.5) |
| Death | 6 (1.8) | 2 (1.3) | 6 (3.9) | 12 (8) | 21 (8.4) |
| Death/LVF | 36 (10.7) | 24 (15.1) | 30 (19.2) | 41 (27.2) | 68 (27.2) |
