Statins and oxidative stress during atherogenesis.

Area of Science:

• Cardiovascular Science
• Oxidative Stress Research
• Pharmacology

Background:

• Oxidised low-density lipoprotein (LDL) is considered highly atherogenic.
• The protective role of antioxidants against LDL oxidation in atherosclerosis is inconsistently supported by human studies.
• Mixed results from observational, epidemiological, and randomized trials highlight the uncertainty regarding antioxidant efficacy in preventing cardiovascular diseases.

Purpose of the Study:

• To review the scientific evidence for the antioxidant activities of statins.
• To evaluate the potential clinical relevance of statins' antioxidant effects in atherosclerosis.
• To explore the role of antioxidants in mitigating LDL oxidation and its impact on cardiovascular health.

Main Methods:

• Literature review of experimental and clinical studies.
• Analysis of data on LDL oxidation markers.
• Examination of epidemiological and randomized trial results concerning antioxidants and cardiovascular outcomes.
• Assessment of studies investigating the antioxidant properties of statins.

Main Results:

• Experimental data support the concept of oxidised LDL being atherogenic.
• Human studies show mixed results on the protective role of antioxidants against cardiovascular diseases.
• Recent findings suggest regular antioxidant intake may inhibit atherosclerosis progression, with reduced LDL oxidisability as a potential marker.
• Statins exhibit antioxidant properties, though their clinical relevance in this context requires further investigation.

Conclusions:

• The precise role of antioxidants in preventing cardiovascular diseases remains incompletely defined.
• Reduced LDL oxidisability may serve as a biomarker for antioxidant intervention efficacy.
• Statins possess antioxidant activities, and their clinical significance in managing atherosclerosis warrants further exploration.
