Investigating Vascular Properties of HEMI and SPG Signals in Individuals With or at Risk for Chronic Kidney Disease (STIMULUS-CKD)

This prospective, single-center clinical investigation conducted in France will evaluate two non-invasive investigational devices (HEMI and SPG-NINOX) designed to assess microcirculation in adults. The study will include 165 participants divided into five groups (33 per group): healthy volunteers, patients with hypertension without chronic kidney disease (CKD), patients with type 2 diabetes without CKD, patients with moderate CKD, and patients with severe CKD. The primary objective is to compare baseline small vessel pressure measured with the HEMI device across groups in order to identify microvascular alterations associated with cardiometabolic and renal disease. Secondary objectives include assessment of microvascular responses after post-ischemic hyperemia, evaluation of SPG-derived small vessel flow and volume parameters, comparison with reference vascular measurements (including SphygmoCor and ultra-high frequency ultrasound), and evaluation of feasibility, acceptability, and measurement reproducibility. Participation is non-randomized, based on participants' pre-existing clinical condition, and study procedures are non-invasive with an expected visit duration of approximately 60 minutes.
