Figure 2. Segmental wall motion index (SWMI) predicted infarct size and functional impairment.
Two days following MI, cardiac function and SWMI were measured by echocardiography. (A) The graph shows a significant correlation between SWMI and MI area (measured at 60 days), validating SWMI as a non-invasive measurement of infarct size. (B and C) The graphs show a significant inverse correlation between SWMI (infarct size, MI area) and functional impairment (ejection fraction, EF) in both male and female mice following MI respectively.
