Abstract:
Objective:To explore the value of two-dimensional speckle tracking echocardiographic imaging (2D-STI) for assessing partial and global left ventricular functional changes at pre-and post-percutaneous coronary intervention (PCI) in patients with chronic total coronary occlusion.
Methods:Echocardiograph was conducted in 23 chronic total coronary occlusion patients at pre-PCI and 1 day, 3, 6 months post-PCI to examine left ventricular ejection fraction (LVEF), meanwhile 2D-STI was applied to obtain the global longitudinal strain (GLS) value of left ventricle.
Results:In all 23 patients, for LVEF, compared with pre-PCI (59.29±12.15)%, it was increased at 3 and 6 months post-PCI (60.00±12.35)%and (61.37±11.8)%respectively, all P<0.05;for GLS value, compared with pre-PCI (-12.77d wit )%, it was decreased at 1 day and 3, 6 months post-PCI (-13.23ecrea)%and (-15.67ecrea)%, (-16.97ecrea)%respectively, all P<0.05.
Conclusion:PCI could effectively improve left ventricular function in patients with chronic total coronary occlusion, 2D-STI technology may quantitatively assess those changes at the early stage.
