Estimation of the Prevalence of Microcirculatory Dysfunction in Uremic Cardiopathy Among Dialysis Patients

Patients with end-stage renal disease have a high burden of cardiovascular mortality, yet ischemic heart disease is often asymptomatic and difficult to diagnose in this population. Recent data suggest that microvascular coronary dysfunction may contribute significantly to myocardial ischemia in dialysis patients, but its true prevalence remains unknown. This study aims to evaluate microcirculatory coronary impairment in hemodialysis patients using invasive coronary angiography with measurement of coronary flow reserve (CFR), index of microcirculatory resistance (IMR). The study will also describe the clinical and biological characteristics associated with microvascular dysfunction in this population, in order to better understand the mechanisms of uremic cardiomyopathy and improve cardiovascular risk stratification.

AVF-MONITOR POC Proof-of-concept Study

This is a proof-of-concept single-centre prospective longitudinal interventional study performed in AVF patients under HD treatment at the Nephrology and Dialysis Department of the ASST-Papa Giovanni XXIII (Bergamo, Italy), involving the recording of AVF sounds by the AVF-MONITOR wearable prototype device. Participants will undergo a screening and enrollment visit, then follow-up visits for AVF sounds registration will be conducted once a week for all participants, prior to dialysis session, over a period of 8 weeks.

Assessment of Mineral and Bone Disorders in Kidney Transplant Recipients

This study aims to integrate bone measurements (including bone turnover markers (BTM), bone mineral density (BMD) measurement, vertebral fracture assessment (VFA), trabecular bone score (TBS) ) commonly used in the general population for primary osteoporosis evaluation to enhance the assessment of CKD-MBD.
