Meta AnalysisTroponins and brain natriuretic peptides for the prediction of cardiotoxicity in cancer patients: a meta-analysis.
Cardiac biomarkers are a mainstay in diagnosis of cardiovascular disease but their role in cardio-oncology has not yet been systematically evaluated. This meta-analysis aims to determine whether cardiac troponins and (N-terminal pro) brain natriuretic peptide (BNP/NT-proBNP) predict cancer therapy-related left ventricular (LV) dysfunction. ⋯ Elevated troponin levels predict LV dysfunction in patients receiving cancer therapy. Assessment of troponin levels may qualify as a screening test to identify patients who require referral to cardio-oncology units and benefit from preventive strategies. Further evidence is required for both biomarkers.

Circulating dipeptidyl peptidase 3 is a myocardial depressant factor: dipeptidyl peptidase 3 inhibition rapidly and sustainably improves haemodynamics.
Acute heart failure is a high mortality disease and its pathophysiology is not completely understood. Dipeptidyl peptidase 3 (DPP3) is a cytosolic enzyme involved in angiotensin II and enkephalins cleavage. The aim of this study was to investigate the association of circulating DPP3 (cDPP3) levels and mortality in cardiogenic shock patients and to determine the effects of high cDPP3 on organ function in a heart failure (HF) model in mice. ⋯ Our study demonstrated cDPP3 is a newly discovered myocardial depressant factor, the levels of which at admission are associated with mortality in severe HF patients. Furthermore, inhibition of cDPP3 by Procizumab improved haemodynamics in a mouse model of HF. Our results suggest that DPP3 could be a new biomarker and biotarget for severe HF.
