Case 1. (A) The previous electrocardiography showed sinus rhythm and left ventricular hypertrophy with T wave inversion in lateral leads (I, aVL, and V4-V6 leads) (left panel). When the patient visited our outpatient clinic for exertional dyspnoea, electrocardiography showed the disappearance of the negative T wave in V4-V6 leads (middle panel). After performing percutaneous coronary intervention for the left anterior descending artery, electrocardiography returned to left ventricular hypertrophy with a negative T wave (right panel). (B) Coronary angiography shows a severe stenotic lesion (99% stenosis) in the left anterior descending artery, and percutaneous coronary intervention was performed for the left anterior descending artery. Case 2. (C) Electrocardiography shows sinus rhythm and left ventricular hypertrophy with negative T wave, especially giant negative T waves in V4-V5 leads (left panel). On a regular outpatient day, electrocardiography showed a decrease in the depth of the negative T wave (middle panel). After coronary artery bypass grafting, the electrocardiography returned to a baseline negative T wave (right panel). (D) Coronary angiography shows three-vessel disease including severe stenosis (90%) of the left anterior descending artery and chronic total occlusion in the right coronary artery. Case 3. (E) Electrocardiography shows sinus rhythm with inverted T waves in I, aVL, and V3-V6 leads (left panel). At the time of admission because of chest discomfort on exertion, electrocardiography showed decreases in the depth of the inverted T waves (middle panel). After percutaneous coronary intervention, electrocardiography shows that the depth of inverted T waves has returned to the previous level (right panel). (F) Coronary angiography shows a severe stenotic lesion in the left anterior descending artery, and percutaneous coronary intervention was performed for the left anterior descending artery. The yellow solid bar shows a stenotic lesion of the coronary artery. The yellow dot bar shows the chronic total occlusion site of the right coronary artery.

Electrocardiography shows sinus rhythm with inverted T waves in I, aVL, and V3-V6 leads (maximum depth of 4 mm in V4 lead) (Figure 1E, left). Electrocardiography shows decreases in the depth of inverted T wave in I, aVL, and V3-V6 leads (maximum depth of 2 mm in V4 lead) (Figure 1E, middle). We immediately performed PCI (Figure 1F). Electrocardiography shows that the depth of inverted T waves has returned to the previous level (maximum depth of 4 mm in V4 lead) (Figure 1E, right).
Echocardiography shows a left ventricular ejection fraction of 72% and diffuses left ventricular hypertrophy in the apex and papillary muscle hypertrophy.

Echocardiography shows a LV ejection fraction of 72%, diffuse LVH in the apex (maximum LV wall thickness of 15 mm), and papillary muscle hypertrophy (Figure 2).
