Objective To analyze the value of 2D speckle tracking imaging on the evaluation of left ventricular function in patients with type 2 diabetes and hypertension.
Methods We selected 87 patients with type 2 diabetes and hypertension as the observation group and 87 cases of healths as the control group from December,2013 to December,2015 in Jinhua Central Hospital.The left ventricular parameters in the two groups were detected by echocardiographic measurements,the left ventricular apex strain of each section were detected by 2D speckle tracking imaging technique.
Results The difference of the left ventricular ejection fraction,diastolic left ventricular wall thickness,diastolic septum thickness and left ventricular diameter in the observation group and control group were not statistically significant(
P>0.05).The diastolic mitral E peak/A peak of the observation group(0.98±0.17) was lower than that of the control group(1.27±0.26),
t=9.243,
P<0.05.The systolic apical left ventricular,left ventricular long axis,four-chamber and two-chamber strain peak in the observation group(-21.8±2.8,-22.2±2.9,-21.7±2.6,-22.2±2.9)were lower than that of the control group(-22.9±3.2,-23.4±3.3,-23.5±2.4,-23.4±2.8),
t=2.525,2.415,3.619,2.335,
P<0.05.The early diastolic left ventricular long axis,four-chamber and two-chamber strain peak in observation group(1.19±0.13,1.20±0.14,1.16±0.23) were lower than that of the control group(1.31±0.28,1.35±0.29,1.28±0.21),
t=2.925,3.274,2.823,
P<0.05.The late diastolic left ventricular long axis,four-chamber and two-chamber strain peak in the observation group(1.18±0.27,1.28±0.29,1.25±0.24) were higher than that of the control group(1.07±0.22,1.17±0.23,1.15±0.18),
t=3.024,2.945,2.657,
P<0.05.
Conclusion 2D speckle tracking imaging technology can early reveal the left ventricular dysfunction in patients with type 2 diabetes and hypertension.
