ECG revealed T-wave inversion in several leads, normal QT interval (Figure 1, FMC), and an increased TPNT level of 108 ng/L. T-wave inversions on several leads without QT interval prolongation (Figure 1). TPNT level was elevated (58 ng/L). ECG now revealed T-wave inversions similar to those found at previous hospitalizations (Figure 1). On day 2, TPNT level increased to 431 ng/L, NT-pro-BNP level was normal, and T-wave inversions on several leads were observed (Figure 1).
