The risk factor age in normotensive patients with pulmonary embolism: Effectiveness of age in predicting submassive pulmonary embolism, cardiac injury, right ventricular dysfunction and elevated systolic pulmonary artery pressure in normotensive pulmonary

Abstract:

INTRODUCTION:Right ventricular dysfunction (RVD), submassive pulmonary embolism (PE), elevated systolic pulmonary artery pressure (sPAP), elevated cardiac troponin I (cTnI) and old age are well-known risk factors for poor outcome in acute normotensive PE. The aim of this analysis was to calculate age cut-off values to predict submassive PE, cardiac injury, RVD and elevated sPAP in normotensive PE patients. METHODS:Retrospective analysis of clinical, laboratory, radiological and echocardiographic data of normotensive PE patients (2006-2011) was performed. Receiver operating characteristic (ROC) curves and Youden indexes were used to test the effectiveness of using patients' ages at the PE event to predict a submassive PE, cardiac injury (elevated cTnI >0.1ng/ml), RVD and elevated sPAP (>30mmHg) in normotensive PE patients and to calculate optimal cut-off values. Patients >76years were compared to those aged ≤76years. RESULTS:129 normotensive PE patients (59.7% women) met the inclusion criteria and were included in this analysis. The optimal cut-off value for patient ages to predict submassive PE, cardiac injury (elevated cTnI >0.1ng/ml), RVD and elevated sPAP (>30mmHg) was 76.5, 81.5, 66.5 and 66.5years, respectively, with moderate effectiveness (AUC 0.69, 0.58, 0.71 and 0.69, respectively). Patients >76years old had higher percentages of submassive PE (91.1% vs. 63.1%, P=0.000680), RVD (91.1% vs. 58.3%, P=0.000119), sPAP (42.64±16.70 vs. 29.24±17.56mmHg, P=0.000044) and cTnI (0.22±0.40 vs. 0.10±0.25ng/ml, P=0.00488). CONCLUSIONS:Age is an important prognostic factor in acute normotensive PE. In addition to cTn and RVD, age should be taken into account in determining the risk stratification for acute PE.
