Abstract:
Objective The tissue motion mitral annular displacement(TMAD)technique was used to evaluate left ventricular longitudinal systolic function in patients with hyperthyroidism,and its correlation with myocardial damage was analyzed.Methods Sixty-nine cases of hyperthyroidism diagnosed in Affiliated Hospital of Youjiang Medical University for Nationalities from July 2021 to November 2022 were selected as the study objects.According to whether the patients were combined with hyperthyroidism heart disease,they were divided into simple hyperthyroidism group(n=43)and thyrotoxic heart group(n=26).35 healthy people who underwent physical examination in our hospital during the same period were selected as normal control group.Three-dimensional echocardiography was used to obtain the left ventricular end diastolic volume(LVEDV),left ventricular end systolic volume(LVESV),left ventricular ejection fraction(LVEF)and TMAD parameters.The differences of above parameters among all groups were compared,and the correlations of TMAD parameters with creatine kinase isoenzymes(CK-MB)and high-sensitivity cardiac troponin T(hs-cTnT)were analyzed.Results The LVEDV,LVESV,LVEF,TMAD parameters,CK-MB and hs-cTnT of three groups were statistically significant(P<0.001),and LVEDV,LVESV,CK-MB and hs-cTnT of normal control groupsimple hyperthyroidism group>thyrotoxic heart group.All parameters of TMAD were positively correlated with LVEF(P<0.001),and some parameters of TMAD were negatively correlated with CK-MB(P<0.05).Conclusion TMAD technology can early evaluate left ventricular longitudinal systolic function in patients with hyperthyroidism,and is related to CK-MB and hs-cTnT.
