Risk stratification in acute pulmonary embolism (APE) includes the assessment of clinical status, right ventricular dysfunction and troponin concentrations. Since acute renal impairment is one of the important predictors of mortality in cardiovascular diseases, the authors hypothesised that it is an independent mortality marker in APE. ⋯ Acute kidney injury assessed by N-GAL occurs in 30% of APE and may contribute to the impairment of renal function present in half of them. Moreover, N-GAL, cystatin C elevation and low eGFR are associated with a poor 30-day prognosis in APE.

Comparative Study
The prognostic value of high sensitivity troponin T 7 weeks after an acute coronary syndrome.
The role of high sensitivity troponin T (hs-TnT) in the convalescence phase after an acute coronary syndrome (ACS) is unknown. The authors aim to assess the prognostic utility of a single hs-TnT level at 7-week post-ACS. Second, the authors evaluated whether any serial changes in hs-TnT between the index admission and 7 weeks post-ACS had any link with the prognosis. Third, the authors assessed whether the prognostic utility of hs-TnT is independent of various echocardiographic abnormalities. ⋯ The authors have demonstrated the prognostic utility of a single 7-week hs-TnT measurement in routine ACS patients and that it could be used to assist medium term risk stratification in this patient cohort. In addition, the authors also showed that hs-TnT predicted long-term adverse prognosis independent of various echo parameters. Future studies should evaluate whether tailoring specific treatment interventions to higher risk individuals as identified by an elevated hs-TnT during the convalescence phase of ACS would improve clinical outcomes.
