The new, high-sensitivity troponin T (hsTnT) assay may improve risk stratification of normotensive patients with acute pulmonary embolism (PE). We externally validated the prognostic value of hsTnT, and of the simplified Pulmonary Embolism Severity Index (sPESI), in a large multicenter cohort.

We prospectively examined 526 normotensive patients with acute PE; of those, 31 (5.9%) had an adverse 30-day outcome. The predefined hsTnT cutoff value of 14 pg/mL was associated with a high prognostic sensitivity and negative predictive value, comparable to those of the sPESI. Both hsTnT ≥14 pg/mL (OR, 4.97 [95% CI, 1.71–14.43]; P=0.003) and sPESI ≥1 point(s) (OR, 9.51 [2.24–40.29]; P=0.002) emerged, besides renal insufficiency (OR, 2.97 [1.42–6.22]; P=0.004), as predictors of early death or complications; in a multivariable model, they remained independent predictors of …
