Methods: We retrospectively analysed data from patients (pts) admitted in one center, with the diagnosis of myocarditis, from 2008 and 2018;
Results: 63 patients were included. Mean age was 38.8 +/- 16 years and 91% (53) were men. Out of those, 58 (94%) had preserved LVEF (mean 59.9 +/- 4.27%) Average length of stay in hospital was 5 days;
The NT-proBNP values ranged from 24 to 3110 pg/mL (median 482 ng/mL; interquartile range (IQR) = 768). Regarding the group of pts with preserved LVEF, 80% (44pts) had plasma levels of NT-proBNP > 120 ng/mL [upper reference limit]; NT-proBNP positively correlated with peak troponin (p= 0.006, r= 0, 37), leucocyte (p= 0.05, r= 0.25) and neutrophil to lymphocyte ratio (p= 0.003, r= 0.26).
Conclusion: In this population, the majority of the patients with myocarditis did not have significant LV systolic dysfunction, as measured by LVEF; Despite that, most of them presented high levels of BNP at admission. In this subset of patients, in which clinical presentation is highly variable, NT-proBNP measurement may be an important adjuvant in early assessment of myocarditis, regardless LVEF;
