Risks with low hs-cTnT concentrations and no initial myocardial infarction compared with the general population
| Peak hs-cTnT concentrations (ng/l) | ||
| <5 ng/L | 5–14 ng/L | |
| All-cause mortality | ||
| Number of patients, n (row, %) | 69 090 (62) | 42 826 (38) |
| Number of deaths, n (%) | 1769 (2.6) | 5534 (13) |
| in-hospital death or death at the index date, n (%) | 4 (0.02) | 35 (0.1) |
| deaths within 30 days, n (%) | 21 (0.03) | 102 (0.2) |
| Deaths per 10 000 person-years, (95% CI) | 38.9 (38.8–39.1) | 212 (211–213) |
| Age-standardised mortality rate (95% CI) | 75.9 (75.8–76.1) | 146 (145–146) |
| Standardised mortality rate ratios (SMRs), (95% CI) | 0.83 (0.79–0.87) | 1.02 (0.99–1.05) |
| Myocardial infarction | ||
| Number of patients who survived the index visit | 69 086 | 42 791 |
| Number of MIs, n (%) | 1281 (1.9) | 2580 (6.0) |
| MIs within 30 days, n (%) | 22 (0.03) | 105 (0.2) |
| Events per 10 000 person-years, (95% CI) | 28.4 (26.9–30.0) | 99.0 (95.3–102.9) |
| Age-standardised incidence rate, (95% CI) | 49.4 (49.2–49.5) | 91.3 (91.1–91.5) |
| Standardised incidence rate ratio (SIR), (95% CI) | 1.39 (1.32–1.47) | 1.56 (1.50–1.62) |
SMR and SIRs were standardised by patient age, sex and calendar year.
hs-cTnT, high-sensitivity cardiac troponin T.
