Factors related to the risk of developing chronic kidney disease in resistant hypertensive patients: a cross-sectional study

OBJECTIVES: to analyze factors related to the risk of developing chronic kidney disease using the SCORED questionnaire in resistant hypertensive individuals. METHODS: this cross-sectional study was conducted at a university hospital in Rio de Janeiro state, between January 2022 and October 2024, with an intentional, non-probabilistic sample of 63 participants. Sociodemographic, clinical, and lifestyle data were collected from medical records, and the Screening for Occult Renal Disease (SCORED) questionnaire was applied via telemonitoring to estimate the risk of chronic kidney disease. Fisher's exact and Mann-Whitney tests were used for statistical analysis. RESULTS: there was a predominance of females (80.3%), mean age of 66.4 ± 10.0 years, ≥ 21 years since diagnosis of hypertension, and 96.8% at risk for kidney disease. CONCLUSIONS: in this first study with resistant hypertensive patients at risk for kidney disease, the related factors were sex, advanced age and time since clinical diagnosis of arterial hypertension.
