Prognosis of patients with acute pulmonary embolism and discordant right ventricle strain serum biomarkers

Right ventricle strain serum biomarkers, such as high-sensitivity cardiac troponin T (hs-cTnT) and NT-pro-brain natriuretic peptide (NT-proBNP), are prognostic in patients with pulmonary embolism (PE). Prognosis accuracy in patients with discordancy between serum biomarkers remains, however, unknown...

Description
Summary:Right ventricle strain serum biomarkers, such as high-sensitivity cardiac troponin T (hs-cTnT) and NT-pro-brain natriuretic peptide (NT-proBNP), are prognostic in patients with pulmonary embolism (PE). Prognosis accuracy in patients with discordancy between serum biomarkers remains, however, unknown. We performed a retrospective analysis in patients with intermediate or high risk PE and discordant serum biomarkers of RV strain as follows: high hs-cTnT and low NT-proBNP (‘high troponin discordance’), compared to patients with low hs-cTnT and high NT-proBNP (‘high NT-proBNP discordance’). Cut-off values for high hs-cTnT were ≥14 pg/mL in patients 75-year. Cut-off values for high NT-proBNP were ≥600 pg/mL. The primary end-point was a composite of death, resuscitated cardiac arrest, mechanical ventilation, and inotrope use at one month. ‘High troponin discordance’, age, sex and body mass index (BMI) were included in a logistic regression model. Time to event analysis was performed using Kaplan Meier curves and Log-rank test. 73 patients were included. ‘High troponin discordance’ patients (n=41) were younger, presented with a higher heart rate, more frequent bilateral PE, and received more thrombolytics as treatment compared with ‘high NT-proBNP discordance’ patients (n = 32). Primary end-point was significantly higher in the ‘high troponin discordance’ patients (29.3% vs 9.4%, p=0.045). ‘High troponin discordance’ was independently associated with the primary end-point after adjusting for age, sex and BMI. Log rank test confirmed worse outcome in the high troponin discordance group (p=0.037). High troponin discordance’ patients with intermediate/high risk PE, had worse outcomes than patients with high BNP discordance. •Thirty six percent of patients with pulmonary intermediate and high risk pulmonary embolism present with discordant serum biomarkers.•Among patients with discordant serum biomarkers, ‘High troponin discordance’ patients presented with higher risk pulmonary embolism, and was associated with worse outcome
