Objective To assess the value of exercise treadmill testing (bruce protocol) in diagnosing early atherosclerotic lesions of the lower limb. Methods Between March and September 2008, 173 outpatients with high risks of peripheral arterial disease (PAD) were enrolled randomly from the cardiology clinic of Chinese PLA General Hospital. The patients were subjected to exercise treadmill testing (Bruce protocol) and ankle-brachial index (ABI) determination, as well as lower limb artery ultrasonography within one week. Using ultrasonic findings as diagnostic criteria, the diagnostic sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of exercise treadmill testing for early atherosclerotic lesions of the lower limb were analyzed, and the diagnostic value of exercise treadmill testing was assessed using the ROC curve. Results After exercise, ABI decrement (R value) increased in subjects with high risks for PAD with atherosclerotic lesions of the lower limb aggravating. Using the presence of large atherosclerotic plaques (area > 20 mm2 ), atherosclerotic plaques and atherosclerotic lesions in lower limb arteries as positive diagnostic criteria, the area under curve of ROC was 0. 80 (95% CI: 0.72-0.88), 0.78 (95% CI: 0.71-0.85) and 0. 60 (95% CI: 0.44-0.76), respectively. Using the presence of large atherosclerotic plaques in lower extremities as positive diagnosis, R value was 0.80, with a sensitivity of 54. 0%, a specificity of 96. 7%, a LR+ of 16. 4, and a LR- of 0. 58, meanwhile, R value was 0. 85, with a sensitivity of 70.0%, a specificity of 91.9%, a LR + of 8.64, and a LR- of 0.33. Conclusions Exercise treadmill testing (Bruce protocol) in combination with ABI determination is a safe, accurate, objective tool for detecting early atherosclerotic lesions of the lower limb. Immediately after exercise, 0.85 is the cut-off R value appropriate for diagnosing large atherosclerotic plaques of the lower limb (area > 20 mm2).

Objective To evaluate the diagnostic accuracy of contrast-enhanced MR angiography (CE MRA) in infrapopliteal occlusive diseases of diabetic patients.Methods A total of 105 patients with known diabetes and peripheral vascular occlusive disease who underwent both CE MRA and DSA examnations were included in this study.They had no obvious stenosis or with stenosis of less than 75％ in iliac,femoral,and popliteal arteries.Every infra-popliteal artery was anatomically divided into 9 vascular segments as tibiofibular trunk artery,proximal and distal anterior tibial artery,proximal and distal posterior tibial artery,proximal and distal peroneal artery,plantar and dorsalis pedis artery.There were 945 segments.The arterial stenosis was accessed with CE MRA and DSA respectively.The segments were scored in 5 categories as＜30％,≥30％ and＜50％,≥50％ and＜75％,≥75％ and＜100％,and 100％ according to stenostic degrees.The Kappa test was used to compare the diagnostic consistency of CE MRA and DSA.Taken DSA as a gold standard for reference,ROC curve was drawn to calculate the diagnostic accuracy of CE MRA in diagnosis of lower limb arterial disease.Results The ratio of statistically valid segments for both CE MRA and DSA were 97.7％ (923/945) in 945 vessel segments of 105 patients,and 390 of 923 arterial segments were both indicated as occlusion by CE MRA and DSA.The diagnostic consistency for the segments was listed in the decreasing order as follows:proximal peroneal artery,proximal posterior tibial artery,distal posterior tibial artery,proximal anterior tibial artery,distal anterior tibial artery,tibiofibular trunk artery,dorsalis pedis artery,plantar artery,distal peroneal artery,and corresponding Kappa values were 0.88,0.86,0.84,0.84,0.81,0.77,0.75,0.75 and 0.73,P＜ 0.05.The AUC(area under ROC curve) of CE MRA was 0.893 with 95％ confidence interval of 0.882 to 0.904.Conclusion CE MRA is an accurate imaging modality in the diagnosis of infrapopliteal occlusive disease s for diabetes.
