Uric acid and cardiovascular disease: A clinical review

Area of Science:

• Cardiovascular Medicine
• Metabolic Disorders
• Nephrology

Background:

• Uric acid is the human end-product of purine metabolism.
• Hyperuricemia, or high uric acid levels, is increasingly prevalent globally.
• Uric acid is a known cause of gout and is implicated in cardiovascular diseases.

Purpose of the Study:

• To review current evidence on the relationship between hyperuricemia and cardiovascular diseases.
• To explore the potential role of uric acid as a predictive marker for cardiovascular outcomes.
• To address the ongoing debate regarding the causal link between hyperuricemia and cardiovascular conditions.

Main Methods:

• Systematic review of clinical investigations.
• Analysis of studies reporting serum uric acid levels and cardiovascular outcomes.
• Synthesis of evidence on hyperuricemia and various cardiovascular diseases including hypertension, atrial fibrillation, chronic kidney disease, heart failure, and coronary artery disease.

Main Results:

• Serum uric acid has been reported as a predictive marker for cardiovascular outcomes in several studies.
• Hyperuricemia is associated with increased risk for conditions like hypertension, atrial fibrillation, chronic kidney disease, and heart failure.
• The causal relationship between hyperuricemia and cardiovascular diseases remains under investigation but is of significant interest.

Conclusions:

• Hyperuricemia is associated with a range of cardiovascular diseases and may serve as a predictive marker.
• Further research is warranted to fully elucidate the causal mechanisms linking high uric acid levels to cardiovascular pathology.
• Understanding the role of uric acid in cardiovascular health is crucial given its rising prevalence worldwide.
