Interaction between the left ventricular ejection fraction and left ventricular strain and its relationship with coronary stenosis

Figure 1 Magnetic resonance imaging results of a 56-year-old woman with hypertension, diabetes, chest tightness, and shortness of breath. A: Functional imaging shows decreased left ventricular end-diastolic systole; B: The perfusion scan shows extensive subendocardial ischemia; C: The delayed scan shows partial myocardial fibrosis. Extensive myocardial ischemia was considered. Partial myocardial infarction causes abnormal cardiac function.
