Magnetic resonance imaging characterization of circumferential and longitudinal strain under various coronary interventions in swine

Figure 4 Time to peak systolic and diastolic strain rate in remote myocardium. Remote myocardium peak systolic (left) and diastolic strain rate (right) in controls and animals subjected to interventions. Only animals subjected to microembolization or combined ischemic insults showed significantly earlier systolic and diastolic strain rates. Data are presented as means ± SEM. Control vs Combined, ^aP < 0.05; Control vs Microemboli, ^dP < 0.001. LAD: Location aid device.
