Clinical course. The solid red line indicates the cTnI level (μg/L). The solid green line indicates the oxygenation index (a ratio of the partial pressure of arterial oxygen to the fraction of inspired oxygen). Horizontal axis indicates time (days) after symptoms onset. b, c, d in textboxes indicates different ECG (for Fig. 1b, c, d and e, respectively). Tha = thalidomide. cTnI = cardiac troponin I
