Figure 1 The electrocardiogram. A: A 12-lead standard electrocardiogram (ECG) of the patient at hospital admission; B: At 10^th day after admission. An ST elevation in leads V1-V2 and T-wave abnormalities can be noted; C: In the repeat ECG, all changes noted in the abnormal ECG have resolved, as can be noted.

Figure 2 The frequency of such episodes of chest pain was increased. A: ProBNP; B: Troponin-T. ProBNP, troponin-T high levels during clinical presentation of patient’s symptomatology. In Y axis, both ProBNP and troponin are measured in pg/mL (normal values; ProBNP < 150 pg/mL, troponine < 14150 pg/mL).

Figure 3 A normal coronary angiography performed at the patient. A: Right coronarogram; B: Left coronarogram; C: Left coronary artery-right anterior oblique; D: Left coronary artery-left anterior oblique.
