Minor kidney dysfunction significantly elevates cardiovascular disease risk in both diabetic and non-diabetic patients. This risk is linked to endothelial dysfunction and various cardiovascular risk factors, potentially stemming from fetal programming.
Area of Science:
- Nephrology
- Cardiology
- Vascular Biology
Background:
- Minor renal dysfunction is an emerging cardiovascular disease (CVD) risk factor.
- This association is observed in both diabetic and non-diabetic individuals.
- Early renal dysfunction presents with abnormalities like microalbuminuria and reduced estimated glomerular filtration rate (eGFR).
Purpose of the Study:
- To explore the link between early renal dysfunction and cardiovascular alterations.
- To identify the common pathways and risk factors connecting kidney and cardiovascular systems.
- To investigate the role of endothelial cell dysfunction and fetal programming in this relationship.
Main Methods:
- Review of evidence linking renal dysfunction to cardiovascular outcomes.
- Analysis of abnormalities associated with early renal dysfunction (e.g., microalbuminuria, reduced eGFR).
- Examination of identified cardiovascular risk factors in patients with renal dysfunction.
Main Results:
- Early renal dysfunction is a potent CVD risk factor, causing cardiovascular alterations.
- Endothelial cell dysfunction appears to be a common pathway.
- Associated risk factors include elevated asymmetric dimethyl-l-arginine, inflammation, oxidative stress, metabolic syndrome, dyslipidemia, and renin-angiotensin system activation.
Conclusions:
- Kidney dysfunction is a significant, independent cardiovascular risk factor.
- Endothelial dysfunction and numerous classical/non-classical risk factors mediate this link.
- Fetal programming, specifically nephron underdosing, is a compelling unifying hypothesis for increased CVD risk.

Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of each...
