简要总结
Analysis of localizations for symptoms and ischemia on treadmill and of the recovery profiles of patients that have had an exercise oximetry
详细描述
Patients referred for exercise oximetry have buttocks thighs and calves recording during exercise and in the recovery period for a minimum of 10 minutes.
For each limb probe the decrease from rest of oxygen pressure (DROP) index is calculated as a subtraction of chest changes from limb changes throughout rest, exercise and recovery. DROP was measured as a routine on buttocks, thighs and calves and a minimal DROP lower than minus 15 mmHg considered indicative of the presence of regional blood flow impairment (ischemia) in the considered area.
Recordings and patients characteristics are recorded on a institutionally validated database.
A comparison will be performed of symptoms by history to symptoms reported on treadmill and hemodynamic results attained through DROP values.
Re-analysis of the recordings after ethical approval will be performed in an aim at estimating the duration of 50% and 90% recovery of DROP at the different levels (buttocks tigh and calves) to account for hemodynamic impairmenty not only at the calf (calves) level.
