Abstract:
Objective To explore the cardiovascular function in type 2 diabetic patients by echo tracking (ET) and instanta-neous wave intensity ( WI) .Methods One hundred and thirty-six retired male veterans were divided into the diabetic group ( n=54) and the control group (n=72), by depending upon whether they had diabetes mellitus .They all received blood lipid detection and ul-trasonography .Echo tracking was used to measure stiffness index (β) , Peterson′s pressure modulus ( Ep) , arterial compliance ( AC) , augmentation index (AI), pulse wave velocity derived from β(PWVβ) on ET curve.Wave intensity was employed to detect accelera-ting wave intensity (W1), decelerating wave intensity (W2) and negative area (NA) on WI curve, as well as the interval between the maximum of R wave and that of W1, and the interval between the maximum of W1 and that of W2(1st-2nd).Results (1) No statisti-cal differences could be seen in age , blood pressure , body mass index , left ventricular ejection fraction and blood lipid , when compari-sons were made between the 2 groups.Blood glucose level [(8.28 ±1.19)mmol/L] in the diabetic group was higher than that [(6.14 ±0.60) mmol/L] of the control group, all with statistical significance(p<0.05).(2) No statistical differences could be noticed in the levels of β, Ep, Ac, AI and PWVβ, when comparisons were made between the 2 groups.(3) W1 and W2 [(10.08 ±6.76) × 103,(1.35 ±1.57) ×103 mmHg· m· s-3] for the diabetic group were significantly lower than those [(13.09 ±11.17) ×103,(2.04 ±1.19) ×103 mmHg· m· s-3] of the control group, all with statistical significance(P<0.05).No statistical differences could be seen in NA, R-1st and 1st-2nd, when comparisons were made between the two groups .Conclusion ET index indicated that carotid e-lasticity in type 2 diabetic patients was not decreased , but W1 could detect early subclinical myocardial lesion in diabetic patients .
