ABSTRACT

Objective:

To explore diagnostic value of ankle brachial index (ABI) combined carotid intima‐media thickness (IMT) for CHD in aged patients with DM.

Methods:

A total of 198 aged DM patients were selected ,including 101 patients complicated with CHD (complicated CHD group ) and 97 non‐CHD patients (pure DM group ).According to number of diseased coronary vessels ,complicated CHD group was further divided into single vessel group (n=29) ,double vessel group (n=41) and multi‐vessel group(n=31).Another 104 healthy aged people were enrolled as healthy control group simultane‐ously.Abnormal ABI rate (percentage of ABI<0.9) and IMT were measured and compared among all groups .With coro‐nary angiography (CAG) as gold standard ,diagnostic value of single and combined detection of ABI and IMT for CHD were analyzed .

Results:

Compared with healthy control group ,there were significant rise in abnormal ABI rate (30.7% vs. 53.6% vs.69.3%) and IMT [(0.78 ± 0.46)mmvs.(1.14 ± 0.53)mm vs.(1.46 ± 0.38)mm]in pure DM group and com‐plicated CHD group ,and those of complicated CHD group were significantly higher than those of pure DM group , P<0.05 or <0.01. Compared with single vessel group ,there was significant rise in abnormal ABI rate (51.7% vs.87.1%) in multi‐vessel group , P=0.003 ;significant rise in IMT [(1.21 ± 0.42)mmvs.(1.42 ± 0.34)mmvs.(1.68 ± 0.36) mm]in double vessel group and multi‐vessel group ,and that of multi‐vessel group was significantly higher than that of double vessel group , P<0.05 or <0.01. Sensitivity and specificity of single detection of ABI<0.9 was 55.6% and 82.2% respectively in diagnosing CHD ;it′s 59.1% and 71.4% respectively for single detection of thickened IMT ;for combined detection ,sen‐sitivity can reach 84.51%(ABI<0.9 or thickened IMT) and sensitivity can reach 88.91%(ABI<0.9 combined thickened IMT).

Conclusion:

ABI combined IMT possesses high diagnostic value screening CHD in aged DM patients ,which is worth extending.
