Blood tests showed significantly increased plasma brain natriuretic peptide (BNP 2600 pg/mL, normal range: 0–125 pg/mL), myocardial enzymes (high sensitivity cardiac troponin T (hs-cTnT) = 27.7 pg/mL, normal range: 0–14 pg/mL) and D-dimer (1670 ng/mL, normal range: 0–500 ng/mL). Other routine blood, biochemistry, liver function and blood coagulation tests were normal.
