ECG and TTE results. A: ECG showed ST elevation in leads of avR/V1-V4 and ST depression in leads of avL/V5-V6 and T wave inversion in leads of avL/I/V5-V6 before PCI procedure. B: TTE showed hypokinesis of global left ventricular wall and ventricular septum with EF of 28% before PCI procedure. C: TTE showed hypokinesis of left ventricular anterior wall and ventricular septum with EF of 40% (1year after PCI procedure). ECG: Electrocardiography; TTE: Transthoracic Echocardiography (TTE)
