Values are represented by the mean* and a measure of the variation of the internal standard deviation. AVR – aortic valve replacement, MVP – mitral valve plasty, MVR – mitral valve replacement, ICU - intensive care unit, GFR – glomerular filtration rate, CRP – C-reactive protein, TnT – troponin T, LV – left ventricle, NT-proBNP – N-terminal of the prohormone brain natriuretic peptide, NYHA – New York Heart Association.
