Doppler Imaging In Evaluating Right Ventricular Function In Patients With Hyperthyroid Cardiopathy

Objective:To evaluate the right ventricular function in patients with hyperthyroid cardiopathy by pulse ultrasonic wave Doppler technique (PW) and Tissue Doppler imaging (TDI).Methods: Sixty patients having hyperthyroidism,whether they have hyperthyroid cardiopathy or not divided into simple hyperthyroidism group(n=37) and hyperthyroid cardiopathy group(n=23).Thirty normal volunteers served as control group.Tricuspid inflow velocity(E) was measured by Doppler echocardiography;TDI-derived systolic tricuspid annular velocity(Sm),diastolic tricuspid annular velocity(Em),the ratio of diastolic tricuspid inflow velocity to Em (E/Em) was caculated.Results:①Compared with control group,Sm was higher in simple hyperthyroidism group(P﹤0.05),Compared with simple hyperthyroidism group, Sm was lower in cardiopathy group(P﹤0.05).②Compared with control group,Em of tricuspid annular lateral wall was lower in hyperthyroid cardiopathy group(P﹤0.05).③The E/Em ratio in hyperthyroid cardiopathy group was significantly higher than that in control group(P﹤0.05),however there were no significant differences between simple hyperthyroidism group and control group(P﹤0.05).Conclusion:PW and TDI can exactly evaluate right ventricular function in patients with hyperthyroid cardiopathy. Objective: To evaluate the clinical value of integrated backscatter(IBS) parameters in hyperthyroidism with hepatic dysfunction.Methods: Sixty patients having hyperthyroidism haven't take medicine yet divided into normal Liver biochemical group(n=29)and abnormal Liver biochemical group(n=31).Fifty volunteers without liver diseases(control group).Integrated backscatter parameters were detected by ultrusound.Thyroid and liver function parameter were measured by vascular blood.Results: IBS and IBS% were significantly higher in the experimental group than those in the control group (P<0.01) .IBS and IBS% in abnormal Liver biochemical group was higher than that in normal Liver biochemical group(P﹤0.05).Correlation analysis:there is positive correlation between FT4 and ALP,ALT(r1=0.501,r2=0.558,P<0.05).IBS% is positive correlation with ALP,ALT,FT4.(r1=0.702,r2=0.617,r3=0.604,P<0.05).Conclusion: Integrated backscatter parameters may be valuable in the assessment of hyperthyroidism with hepatic dysfunction,especially in the assessment of early damage.
