ABSTRACT
Objective To assess the right ventricular (RV) performance in patients with type 2 diabetes mellitus (2-DM) by two-dimensional speckle tracking imaging (2D-STI),and to explore the clinical value of RV longitudinal strain and strain rate.Methods Thirty-seven patients with 2-DM only and thirtyone patients coexisting diabetes and hypertension (DM + HTN) were studied.Thirty-nine healthy age matched persons served as control subjects.In each patient a conventional two-dimensional echocardiography was performed and also an echocardiographic study with strain/strain rate imaging was studied.Analysis of RV longitudinal systolic strain were obtained in the apical four-chamber view of the RV for the assessment of the RV free wall(F-PLSS),interventricular septum (S-PLSS) and the global RV wall (G-PLSS).The entire RV longitudinal peak systolic strain rate (G-SRs),peak early-diastolic strain rate (G-SRe) and peak late-diastolic strain rate (G-SRa) were performed in the apical four-chamber view.Results Compared with controls,F-PLSS,S-PLSS,G-PLSS,G-SRs and G-SRe were decreased in 2-DM and DM + HTN (all P <0.01),with lower values in DM + HTN (P <0.05).In the patients coexisting diabetes and hypertension,G-SRa was significantly lower than those in the control group (P < 0.05).Compared with 2-DM,this difference was not significant in controls and DM + HTN (P >0.05).Conclusions No matte the patients of 2-DM with or without hypertension,the early changes of RV dysfunction can be found by 2D-STI.Patients coexisting diabetes and hypertension may have worse RV dysfunction.
