Abstract:
Objective To investigate the value of echocardiography in assessing right ventricular function of primary light-chain amyloidosis(AL)-cardiac amyloidosis(CA)patients.Methods A total of 25 patients biopsy diagnosed as AL-CA,who were admitted to the First Affiliated Hospital of Wenzhou Medical University from January 2018 to December 2021,were enrolled in this study as amyloidosis group.And 25 heathy volunteers were set as control group.The routine right ventricular morphology and functional parameters were acquired by standard echocardiography.Right ventricular global longitudinal strain(RVGLS)and right ventricular free wall longitudinal strain(RVfwLS)were obtained by two-dimensional speckle tracking imagine.Tricuspid annular plane systolic excursion(TAPSE)/pulmonary artery systolic pressure(PASP),RVGLS/PASP,RVfwLS/PASP ratio were calculated as the noninvasively parameters of right ventricular-pulmonary artery coupling.Results ①Compared with control group,patients in amyloidosis group showed significantly larger right heart size,and significantly thicker right ventricular free wall[(7.16±1.84)mm vs.(3.76±0.66)mm],the difference was statistically significant(P<0.001).②Compared with control group,RVGLS[(17.43±2.45)%vs.(23.22±3.73)%]and RVfwLS[(18.44±2.10)%vs.(22.62±3.64)%]were significantly impaired in amyloidosis group,the difference was statistically significant(P<0.001).The ratios of TAPSE/PASP,RVGLS/PASP,RVfwLS/PASP were found to be lower in amyloidosis group,the difference was statistically significant(P<0.001).③TAPSE/PASP showed mild correlations with N-terminal brain natriuretic peptide precursor(NT-proBNP),highly sensitive T cardiac troponin(hs-TNT)(r=0.45 and 0.40)there were statistically significant(P<0.05).Conclusion Echocardiography can effectively evaluate the right heart function impairment in AL-CA patients,providing valuable information for a deeper understanding of the pathological and physiological mechanisms of the disease.
