Evaluate the Correlation of NIRS, ABI, Exercise, baPWV and Albuminuria With Peripheral Artery Occlusion Disease (PAD) and Other Atherosclerosis Outcomes

By utilizing Near infrared spectroscopy (NIRS), the local blood flow, tissue oxygenation (StO2), and recovery time of ischemic leg; can be determined. It is reasonable to standardize an easy, simple and safe Active Pedal Plantarflexion (APP) exercise test working load which can achieve the lowest StO2 and other parameters in ischemic leg through observation of NIRS. After standardized of an effective APP test, a determination of a new cutoff value of resting ABI in diagnosing PAD can probably be searched. Analysing the correlation of baPWV with ABI, atherosclerosis risk factors and parameters with atherosclerosis outcome. Observation the Sequential changes of baPWV, ABI and microalbuminuria after managing the atherosclerosis risks, and analyze their influence on the outcome of PAD, coronary artery disease(CAD) and cerebral vascular disease(CVA) outcomes.
