Researchers are evaluating the rate of chronic kidney disease (CKD) diagnosis in adults with arterial hypertension (AH) who have laboratory markers indicating possible CKD but no prior recorded CKD diagnosis. The study focuses on patients without diabetes mellitus or symptomatic chronic heart failure and aims to better understand CKD prevalence in this specific population in Russia. This multi-center, non-interventional, observational study includes both prospective and retrospective data analysis involving about 10,000 adult outpatients from approximately 50 outpatient sites across 20 regions of Russia. The study will not involve any new diagnostic or treatment procedures beyond routine clinical practice. Retrospective data will be collected from medical records to identify CKD markers measured within 12 months before study inclusion. Patients with adequate retrospective data may have CKD diagnosis confirmed based on two evaluations at least 3 months apart. Those without sufficient retrospective data will undergo laboratory testing during the prospective study period, which will last up to 18 months or until data from 10,000 patients are collected. Participants will be monitored and treated by cardiologists or internal medicine specialists during routine visits. Researchers will collect demographic and clinical information, including medical history and CKD markers, from both retrospective and prospective records. The main outcome is the rate of new CKD diagnoses over the 18-month follow-up. No additional interventions or procedures beyond usual care will be performed, and the study aims to support earlier CKD detection and improved clinical outcomes in patients with hypertension.
