Human serum albumin in cardiovascular diseases

Area of Science:

• Cardiology
• Biochemistry
• Internal Medicine

Background:

• Cardiovascular diseases (CVDs) are a leading global cause of mortality.
• Endothelial dysfunction, inflammation, and oxidative stress are key in atherosclerosis and CVD development.
• Low serum albumin levels (hypoalbuminemia) correlate with various CVDs, independent of traditional risk factors.

Purpose of the Study:

• To review the physiological functions of serum albumin.
• To examine the prevalence, causes, and prognostic significance of hypoalbuminemia in CVD.
• To discuss hypoalbuminemia's potential role in CVD onset and progression.

Main Methods:

• Literature review of epidemiological and clinical studies.
• Analysis of the physiological properties of serum albumin.
• Synthesis of evidence on hypoalbuminemia as a risk and prognostic factor in cardiovascular diseases.

Main Results:

• Serum albumin possesses anti-inflammatory, antioxidant, anticoagulant, and antiplatelet aggregation properties.
• Hypoalbuminemia is an independent prognosticator in coronary artery disease, heart failure, stroke, and other cardiovascular conditions.
• Hypoalbuminemia may represent an unrecognized, modifiable risk factor for cardiovascular diseases.

Conclusions:

• Hypoalbuminemia is strongly associated with increased risk and poorer prognosis in cardiovascular diseases.
• Understanding albumin's physiological roles highlights its importance in cardiovascular health.
• Further research into modifiable strategies to address hypoalbuminemia is warranted for clinical implications.
