Abstract Aims Our aim is to investigate the characterized echocardiographic cardiac measurements of POEMS syndrome and determine its relationship with clinical manifestations. Methods and Results The cross‐sectional study included 27 treatment‐naïve patients with newly diagnosed POEMS syndrome and 26 age‐ and sex‐matched healthy volunteers. Information of clinical manifestations, serological tests, pulmonary function tests, and both conventional echocardiograph and tissue Doppler imaging (TDI) were collected and analyzed. Pearson's correlation coefficient was used for determining the related clinical and echocardiographic parameters. Compared to healthy people, left ventricular (LV) mass index (LVMI) was elevated in patients with POEMS syndrome (41.3 ± 11.0 g/m 2.7 , P < .05). LV systolic dysfunction was found by decreased mitral S′ (9.0 ± 2.2 m/sec, P < .01), and diastolic dysfunction by mitral E’/A’ (1.10 ± 0.42, P < .05), E/E’ (8.69 ± 4.06, P < .001) on lateral, and E/E’ (7.90 ± 3.28, P = .133) on septal mitral annulus. The presence of decreased tricuspid annular plane systolic excursion (TAPSE) (22.2 ± 3.5 mm, P < .01) and lateral tricuspid S′ (11.1 ± 1.8 m/sec, P < .05) suggested deterioration of right ventricular (RV) systolic function. Parameters obtained from standard echocardiograph (tricuspid E/A ratio and DT) and TDI ((lateral tricuspid annulus E’/A’ and E/E’) indicated reduced RV diastolic function. Pulmonary hypertension (PH) was presented in six patients. Correlation analysis suggested that PH was related to total lung capacity (TLC) and diffusion capacity of carbon monoxide (DLCO). Conclusion Echocardiographic measurements found that there was elevation of LVMI, pulmonary artery hypertension, and subclinical impairment of systolic and diastolic functions of both the right and left heart in patients with POEMS syndrome.
