Renal disease in cardiovascular disorders: an underrecognized problem

Area of Science:

• Nephrology
• Cardiology
• Public Health

Background:

• Chronic kidney disease (CKD) is a significant and escalating global health concern.
• CKD is underrecognized in cardiovascular disease (CVD) patients, despite its prevalence and impact.
• Minor renal function impairments are common in CVD and predict cardiovascular events.

Purpose of the Study:

• To highlight the underrecognized role of renal disease in cardiovascular patients.
• To emphasize the predictive value of renal disease markers for cardiovascular morbidity and mortality.
• To advocate for improved recognition and management of CKD in at-risk populations.

Main Methods:

• Review of evidence linking renal function markers (GFR, microalbuminuria) to cardiovascular outcomes.
• Analysis of the predictive power of renal disease markers compared to conventional risk factors.
• Discussion of screening protocols and risk factor control for renal protection.

Main Results:

• Markers of renal disease, including microalbuminuria, are prevalent in cardiovascular disease states.
• Renal disease markers are as predictive of morbidity and mortality as traditional risk factors in patients with hypertension, diabetes, and stroke.
• Current clinical practice shows poor recognition and management of renal disease in at-risk individuals.

Conclusions:

• Even mild renal dysfunction significantly impacts cardiovascular outcomes.
• Microalbuminuria may indicate systemic vascular disease, not solely kidney dysfunction.
• Improved screening using GFR estimates and better risk factor management are essential for renal and cardiovascular protection.
