cardiovascular disease in patients with chronic kidney disease: polish kidney- heart project

Conditions: Chronic Kidney Disease; Cardiovascular Diseases

Summary: this is an observational longitudinal study which will collect routine demographic, laboratory and clinical parameters of patients with chronic kidney disease (ckd) in the silesian and warmia and mazury regions (poland) aimed at predicting incident cardiovascular disease and cardiovascular and renal events using machine learning and artificial intelligence approaches. there will be a subgroup analysis of patients with diabetes and ckd.

this is a prospective, observational study seeking to collate demographic, laboratory, and clinical data from patients with ckd hospitalized at two academic centres: the department of internal medicine, diabetology and nephrology in zabrze, silesia, and the clinic of nephrology, hypertension and internal medicine in olsztyn, warmia and mazury. patients will receive telephone check-ups annually post-discharge and will be proposed to attend on-site follow-up health checks. patients will be followed up annually for 10 years or until death if occurs earlier, in order to collect information related to new onset cardiovascular events and progression to macroalbuminuria and/or doubling of serum creatinine with decrease of egfr to less than 45 ml/min./1.73m2 (compared to baseline) or the onset of end stage renal disease (esrd) or renal death. esrd is defined as initiation of maintenance dialysis or kidney transplantation. all procedures, except eye fundus imaging for hospitalized patients align with standard nephrology ward care that patients agree for upon hospitalization. the medical university of silesia and the university of warmia and mazury, collegium medicum obtained study approvals from the respective independent university- or chamber of physicians-based bioethics committees for performing fundus imaging during hospital stay and annual telephone contacts as well as on- site health checks for the longitudinal patient follow-up observation. with patient consent, annual on-site visits will entail blood and urine assessments, ecg, retinal imaging via the fundus camera, and examinations for peripheral and cardiac autonomic neuropathy among those with diabetes. biochemical analyses will focus on assessing serum creatinine, lipid profile, hba1c for diabetic patients, and the urine albumin-creatinine ratio (uacr). with a decade-long prospective follow-up focused on documenting new cardiovascular and renal events, the primary objective is to identify patients with ckd at the highest risk of cardiovascular disease and ckd progression. this goal will be achieved by implementing machine learning techniques to analyze clinical parameters that are easy to obtain in everyday clinical practice.

Eligibility criteria:
inclusion criteria: * ckd defined as estimated glomerular filtration rate (egfr) \ 30 mg/g lasting at least 3 months * ckd regardless of egfr/albuminuria when documented otherwise (by means of imaging, renal biopsy result, genetic background, etc) exclusion criteria: * death during hospital stay * terminal stage of cancer * lack of an informed consent
