One serum aliquot was used for measurement of biochemical parameters using commercial reagents (Beckman Coulter) per manufacturer's instructions in an automatic analyser (Olympus
AU 640, Hamburg, Germany). The following parameters were measured: serum urea, creatinine, bilirubin, glucose, proteins, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), alkaline phosphatase (AP), creatine kinase (CPK), lactate dehydrogenase (LDH), C-reactive protein (CRP), alpha-amylase, lipase, cholesterol, triglycerides, calcium, phosphates.
Cardiac troponin I (cTnI) was measured using a commercially available ADVIA Centaur TnI-Ultra assay, which is a high-sensitivity immunoassay validated for use in both humans and dogs [10] . Analysis was performed in Dubrava Clinical Hospital, Department of clinical diagnostics (Zagreb, Croatia) using Siemens
Advia Centaur XP according to manufacturer's instructions. Samples which had serum concentration of cTnI below the lower level of detection of the assay were allocated a value of 0.01 μg/L. Analysis of N-terminal pro b-type natriuretic peptide (NT-proBNP) concentration in all samples was performed in Vet Med Labor GmbH, reference IDEXX Laboratory (Germany) using IDEXX
Cardiopet® proBNP test.
