Sensitivity and Specificity of the AHA Post-exercise ABI Criteria in Peripheral Artery Disease Patients

What this Trial Is About

Researchers are evaluating exercise testing in patients suspected of Peripheral Artery Disease (PAD) to understand how exercise-related measurements relate to imaging findings. This observational study is conducted at a single center and includes all patients referred to the vascular unit for exercise testing as part of routine clinical care. The study uses data collected during a usual consultation, focusing on parameters such as resting pressure and exercise test results. Patients undergo exercise testing, and their data are analyzed to explore the relationship between these measurements and imaging findings. The main measurement is the Ankle-Brachial Index (ABI) taken at 1 minute after stopping walking, with additional measurements at 3 and 5 minutes. Participants provide data during their usual visits, with no additional interventions beyond standard care. Researchers collect exercise test results and imaging data, then analyze these to assess PAD indicators. The study tracks ABI values at specific times after exercise to evaluate vascular response. Participation involves routine clinical assessments without extra procedures, and the study runs until the end of 2030.
