Insights
Cardiovascular risk factors like hypertension and diabetes worsen with chronic kidney disease (CKD) progression. Management targets become harder to reach in advanced CKD stages, especially for hypertension in very high-risk patients.
Area of Science:
- Nephrology
- Cardiology
- Public Health
Background:
- Cardiovascular disease (CVD) is a major complication in chronic kidney disease (CKD).
- Effective management of cardiovascular risk factors is crucial for CKD patients.
- Limited data exist on the prevalence and treatment of CVD risk factors across CKD stages in clinical practice.
Purpose of the Study:
- To investigate the burden and treatment status of cardiovascular risk factors in non-dialysis-dependent CKD patients.
- To analyze how these factors and their management vary across different CKD severity stages.
Main Methods:
- Cross-sectional analysis of 3,407 non-dialysis-dependent CKD patients from the Fukuoka Kidney disease Registry Study.
- Patients stratified into five risk groups based on KDIGO 2012 guidelines (eGFR and albuminuria).
- Logistic regression used to assess the association between CKD risk groups and cardiovascular risk factor treatment.
Main Results:
- Hypertension, diabetes mellitus, and dyslipidemia prevalence increased with CKD severity.
- Achievement rates for cardiovascular risk factor treatment targets decreased as CKD progressed.
- Extremely high-risk CKD patients had significantly higher odds of uncontrolled hypertension (OR 3.68) compared to low-risk patients.
Conclusions:
- CKD patients exhibit a growing burden of cardiovascular risk factors as kidney disease severity increases.
- Managing hypertension poses a significant challenge in extremely high-risk CKD patients.
Aim:
Cardiovascular disease is a life-threatening chronic kidney disease (CKD) complication. Although cardiovascular risk factor management is significant in patients with CKD, there are few reports that detail the frequency of complications and the treatment of cardiovascular risk factors at different stages of CKD in clinical practice.
Methods:
There were a total of 3,407 patients with non-dialysis-dependent CKD who participated in the Fukuoka Kidney disease Registry Study, and they were cross-sectionally analyzed. The patients were classified into five groups based on their estimated glomerular filtration rate and urinary albumin to creatinine ratio according to Kidney Disease: Improving Global Outcomes 2012 guidelines, which recommend low, moderate, high, very high, and extremely high risk groups. The primary outcomes were the cardiovascular risk factor burden and the treatment status of cardiovascular risk factors. Using a logistic regression model, the association between the CKD groups and the treatment status of each risk factor was examined.
Results:
The proportion of patients with hypertension, diabetes mellitus, and dyslipidemia significantly increased as CKD progressed, whereas the proportion of patients who achieved cardiovascular risk factor treatment targets significantly decreased. In the multivariable analysis, the odds ratios (ORs) of uncontrolled treatment targets were significantly higher for hypertension (OR 3.68) in the extremely high risk group than in the low risk group.
Conclusions:
Patients with non-dialysis-dependent CKD demonstrate an increased cardiovascular risk factor burden with greater severity of CKD. Extremely high risk CKD is associated with difficulty in managing hypertension.
