Increased cardiovascular risk in patients with chronic kidney disease

Area of Science:

• Nephrology
• Cardiology
• Internal Medicine

Background:

• Cardiovascular disease (CVD) is a major concern for patients with chronic kidney disease (CKD).
• Increased cardiovascular risk is evident even in early stages of CKD.
• The relationship between declining kidney function and cardiovascular risk is intricate and influenced by multiple factors.

Purpose of the Study:

• To review the impact of traditional cardiovascular risk factors on CKD patients.
• To explore CKD-specific pathophysiological and molecular mechanisms contributing to cardiovascular risk.
• To highlight the need for understanding complex interactions for novel therapeutic strategies.

Main Methods:

• Literature review of traditional cardiovascular risk factors (smoking, dyslipidemia, diabetes, hypertension).
• Analysis of CKD-specific mechanisms including uremic toxins, inflammation, oxidative stress, endothelial dysfunction, coagulation abnormalities, vascular calcification, RAAS and sympathetic activation, and anemia.
• Discussion of the interplay between these factors.

Main Results:

• Traditional risk factors significantly elevate CVD risk in CKD.
• CKD-specific factors like uremic toxins, inflammation, oxidative stress, and endothelial dysfunction are critical contributors.
• Altered coagulation, vascular calcification, and hormonal/neural activation exacerbate cardiovascular risk.

Conclusions:

• The high prevalence of CVD in CKD stems from a combination of traditional and unique CKD-related mechanisms.
• Further research into the complex interplay of these factors, potentially in specific patient subgroups, is crucial.
• Identifying novel therapeutic targets is essential to mitigate the elevated cardiovascular risk in CKD patients.
