Recent Updates on Current and Upcoming Biomarkers for Cardiovascular Diseases

Area of Science:

• Biochemistry
• Cardiology
• Molecular Biology

Background:

• Cardiovascular disease (CVD) presents complex, multifactorial origins including cardiac membrane damage, inflammation, oxidative stress, apoptosis, and mitochondrial dysfunction.
• Late diagnosis of CVD contributes to high mortality and poor clinical outcomes, necessitating improved diagnostic tools.
• Overlapping symptoms across CVD types like myocardial infarction, angina, and heart failure highlight the need for multi-marker approaches.

Purpose of the Study:

• To review established and novel biomarkers for cardiovascular disorders.
• To discuss biomarkers related to oxidative stress, inflammation, membrane damage, plaque rupture, and thrombosis.
• To emphasize the importance of supportive biomarkers for targeted CVD diagnosis and management.

Main Methods:

• Literature review of established and novel biomarkers for cardiovascular diseases.
• Discussion of biomarker categories including those for oxidative stress, inflammation, apoptosis, membrane damage, and energy metabolism.
• Analysis of the role of biomarkers in pre-clinical studies for assessing cardioprotective potential.

Main Results:

• Current biomarkers like CK-MB, cTnT, BNP, and MPO are insufficient for complex CVD diagnosis.
• Novel multi-markers are being developed to address oxidative stress, inflammation, apoptosis, membrane damage, and energy metabolism.
• Validation through statistical criteria (reclassification, discrimination, calibration) is crucial for clinical adoption of novel biomarkers.

Conclusions:

• Accurate and specific biomarkers are essential for timely CVD diagnosis and prevention.
• Multi-marker strategies incorporating novel indicators are vital for managing complex cardiovascular conditions.
• Further validation is required to integrate promising novel biomarkers into clinical practice for improved patient outcomes.
