- Abstract
- High-sensitivity troponin T (hsTnT) helps in identifying pulmonary embolism patients at low risk of an adverse outcome. In 682 normotensive pulmonary embolism patients we investigate whether an optimised hsTnT cut-off value and adjustment for age improve the identification of patients at elevated risk. Overall, 25 (3.7%) patients had an adverse 30-day outcome. The established hsTnT cut-off value of 14 pg.mL(-1) retained its high prognostic value (OR (95% CI) 16.64 (2.24-123.74); p=0.006) compared with the cut-off value of 33 pg.mL(-1) calculated by receiver operating characteristic analysis (7.14 (2.64-19.26); p<0.001). In elderly (aged >= 75 years) patients, an age-optimised hsTnT cut-off value of 45 pg.mL(-1) but not the established cut-off value of 14 pg.mL(-1) predicted an adverse outcome. An age-adjusted hsTnT cut-off value (>= 14 pg.mL(-1) for patients aged <75 years and >= 45 pg.mL(-1) for patients aged >= 75 years) provided additive and independent prognostic information on top of the simplified pulmonary embolism severity index (sPESI) and echocardiography (OR 4.56 (1.30-16.01); p=0.018, C-index=0.77). A three-step approach based on the sPESI, hsTnT and echocardiography identified 16.6% of all patients as being at higher risk (12.4% adverse outcome). Risk assessment of normotensive pulmonary embolism patients was improved by the introduction of an age-adjusted hsTnT cut-off value. A three-step approach helped identify patients at higher risk of an adverse outcome who might benefit from advanced therapy.
