Abstract:
Objective :To study correlation between brachial‐ankle pulse wave velocity (baPWV ) and cardiac auto‐nomic nervous function in patients with type 2 diabetes mellitus (T2DM) and its influencing factors .Methods :A to‐tal of 293 T2DM patients ,who hospitalized in our hospital from May 2015 to May 2016 ,were selected .According to baPWV level ,patients were divided into normal baPWV group (n＝198 ,≤1400cm／s) and abnormal baPWV group (n＝95 ,＞1400cm／s).Blood pressure ,heart rate ,blood glucose ,renal function and heart rate variability (HRV) indexes were measured and compared between two groups .Multi‐factor Logistic regression analysis was used to ana‐lyze influencing factors of baPWV .Results :Compared with normal baPWV group , there were significant rise in age ,levels of systolic blood pressure (SBP) ,diastolic blood pressure (DBP) ,central venons pressure (CVP) , pe‐ripheral arterial pressure (PAP ) , percentage of peripheral neuropathy and mean heart rate and significant reduc‐tions in HRV indexes :lgTF (total frequency) ,lgHF (high frequency) ,lgSDNN (standard deviation of normal to normal RR intervals calculated over the 24 h period) and lgrMSSD (root‐mean square of differences between succes‐sive normal to normal intervals) and slgnificant rise in lgSDANN (standard deviation of normal to normal RR inter‐vals in all 5 min segments of the entire recording ) in abnormal baPWV group , P＜0. 05 or ＜0.01 .Multi‐factor Lo‐gistic regression analysis indicated that SBP ,DBP ,PAP ,CVP , heart rate SDANN and peripheral neuropathy were independent risk factors for baPWV (OR＝1.031－2. 108 , P＜0.05 or ＜0.01) ,while TF ,HF and rMSSD were its independent protective factors (OR＝0. 468－0. 595 , P＜0.05 or ＜0. 01) in T2DM patients .Conclusion :In patients with type 2 diabetes mellitus , abnormal pulse wave velocity is closely correlated with cardiac autonomic nervous function damage ,and it′s affected by blood pressure and blood glucose etc .
