Study of Systolic Rise Time Measurement to Predict Limb and Cardiovascular Risks in Adults with Critical Limb Ischemia from Peripheral Artery Disease

What this Trial Is About

Peripheral artery disease PAD is a common vascular condition caused by atherosclerosis, with symptoms ranging from mild leg pain during walking to severe critical limb ischemia. This stage of PAD involves rest pain or tissue damage and carries a high risk of cardiovascular death and acute ischemic events. The study focuses on evaluating a new measurement, the Systolic Rise Time SRT in the foot, to assess its ability to predict major adverse limb and cardiovascular events in patients with critical limb ischemia. The study involves measuring the Systolic Rise Time using an ultrasound probe on the foot during routine Doppler echography. This measurement is performed before surgery, after surgery, and at a 6-month follow-up. Participants include adults with critical limb ischemia due to atherosclerosis who are eligible for surgical revascularization and are followed at a specialized hospital. Participants will undergo these ultrasound assessments as part of their standard care at scheduled times. Researchers will monitor the occurrence of limb ischemia over 6 months as the primary outcome. The study helps to understand the prognostic value of this hemodynamic marker to guide treatment decisions and improve patient monitoring. Participation lasts through the 6-month follow-up period, with data collected during routine clinical visits.
