Insights
Patients with chronic kidney disease (CKD) face a high risk of cardiovascular disease (CVD), particularly coronary artery disease (CAD). This review covers the epidemiology, pathophysiology, and clinical aspects of CAD in CKD patients.
Area of Science:
- Nephrology
- Cardiology
- Internal Medicine
Background:
- Cardiovascular diseases (CVD), especially coronary artery disease (CAD), are leading causes of death in chronic kidney disease (CKD) patients.
- CKD is an independent risk factor for CAD, with factors like malnutrition, inflammation, and atherosclerosis contributing to heightened risk.
Purpose of the Study:
- To review the epidemiologic, pathophysiologic, and clinical aspects of CAD in CKD patients.
- To highlight the independent association between decreased glomerular filtration rate (GFR), proteinuria, and CAD.
Main Methods:
- Review of classical and recent literature on CAD in CKD.
- Analysis of epidemiologic, pathophysiologic, and clinical data.
Main Results:
- CKD significantly increases the risk of CAD due to multiple contributing factors.
- Reduced GFR and proteinuria are independently linked to CAD in community studies.
Conclusions:
- CAD is a major concern in CKD management.
- Understanding the multifaceted relationship between CKD and CAD is crucial for patient outcomes.
Abstract:
Despite the improvements in diagnostic tools and medical applications, cardiovascular diseases (CVD), especially coronary artery disease (CAD), remain the most common cause of morbidity and mortality in patients with chronic kidney disease (CKD). The main factors for the heightened risk in this population, beside advanced age and a high proportion of diabetes and hypertension, are malnutrition, chronic inflammation, accelerated atherosclerosis, endothelial dysfunction, coronary artery calcification, left ventricular structural and functional abnormalities, and bone mineral disorders. Chronic kidney disease is now recognized as an independent risk factor for CAD. In community-based studies, decreased glomerular filtration rate (GFR) and proteinuria were both found to be independently associated with CAD. This paper will discuss classical and recent epidemiologic, pathophysiologic, and clinical aspects of CAD in CKD patients.
