Chronic kidney disease in outpatients with arterial hypertension: clinical characteristics and treatment efficacy (according to the national registry)

Abstract

Аim. To investigate the clinical characteristics and quality of treatment (according to the national guidelines) of patients with arterial hypertension (AH) and chronic kidney disease observed in primary health care. Materials and methods. The study was carried out on the basis of the AH registry data (n=43 133; 20052019 years). Glomerular filtration rate (eGFR) was calculated using the CKD-EPI formula; renal structure and albuminuria were not evaluated. The analysis was performed using the SPSS software (version 22; SPSS Inc). Results. The creatinine level was assessed in 60% of patients, 23.6% of them had decreased eGFR60 ml/ min/1.73 m2. The incidence of co-morbid CVD and type 2 diabetes in patients with hypertension increased markedly with a decrease in eGFR (14 groups): the incidence of coronary artery disease increased 1.8 times (up to 72.5%), myocardial infarction 1.7 times (up to 20.6%), chronic heart failure 2 times (up to 84.0%), atrial fibrillation 10 times (up to 18.3%), history of stroke 3.7 times (up to 15.3%) and type 2 diabetes 2.4 times (up to 32.8%). Achievement of target goals of CV risk factors was not enough: systolic BP less than 50% of patients, triglycerides less than 7%, LDL-C in high and very high CVD risk patients less than 13%. Conclusion. Conducting timely assessment of renal function, drug therapy and lifestyle changes in patients with AH and decreased renal functional could prevent severe kidney damage, the development of CV complications, chronic renal failure and reduce mortality.
