Abstract:
Objective To explore the correlation between brachial and ankle pulse wave conduction velocity(baPWV)and cardiac structure and function in patients with type 2 diabetes mellitus(T2DM).Methods A total of 443 patients with T2DM who were treated in The Endocrinology Department of Gansu Provincial People's Hospital were enrolled in this study from June 2022 to October 2023.All the patients were divided into simple T2DM group(T2DM,baPWV<1400 cm/s,n=221)and atherosclerosis group(AS,baPWV≥1400 cm/s,n=222)based on baPWV.The cardiac ultrasound diagnostic instrument was used to record left ventricular ejection fraction(LVEF),end diastolic left ventricular diameter(LVd),end diastolic interventricular septal thickness(IVSd),end diastolic left ventricular posterior wall thickness(LVPWd),ratio of early to late diastolic peak velocity of mitral valve annulus(E/A),and ratio of early diastolic peak velocity of mitral valve orifice to early diastolic peak velocity of mitral valve annulus(E/E').Results Age,DM duration,SBP,DBP,HbA1c,TG,ABI,LVEF,IVSd,LVPWd,E/A<1,E/E'＞14,were higher in AS group than in T2DM group(P<0.05 or P<0.01).Spearman correlation analysis shows that E/A<1 was positively correlated with age,DM duration,BMI,SBP,DBP,and ABI(P<0.05 or P<0.01),while negatively correlated with baPWV(P<0.01).Pearson correlation analysis shows that LVPWd was positively correlated with age,DM duration,BMI,SBP,DBP,baPWV,and Scr(P<0.05 or P<0.01).Logistic regression analysis shows that baPWV,ABI,and SBP were the influencing factors for left ventricular diastolic dysfunction.The analysis of the working characteristic curve of the subjects shows that the area under the curve of baPWV,SBP and ABI for predicting left ventricular diastolic dysfunction is 0.647,0.643,and 0.624,with the best cutoff points being 1398.5 cm/s,125.5 mmHg,and 1.107.Conclusions baPWV is closely related to cardiac structure and function in T2DM patients.As baPWV increases,the risk of left ventricular diastolic insufficiency and hypertrophy rises.
