Cardiovascular diseases, depression disorders and potential effects of omega-3 fatty acids

Area of Science:

• Medical Science
• Pathophysiology
• Nutritional Science

Background:

• Cardiovascular disease (CVD) and depressive disorders (DD) are leading global health issues.
• Both conditions, despite different origins, share common pathophysiological characteristics and risk factors.
• These shared factors include inflammation, endothelial dysfunction, metabolic changes, and oxidative stress.

Purpose of the Study:

• To investigate the common underlying factors contributing to both cardiovascular disease and depressive disorders.
• To explore the role of historical dietary changes in the development of these shared pathophysiological characteristics.

Main Methods:

• Review of current scientific findings on CVD and DD.
• Analysis of pathophysiological characteristics and risk factors common to both conditions.
• Examination of the impact of dietary changes, specifically the omega-6 to omega-3 fatty acid ratio, on metabolism.

Main Results:

• Shared risk factors include increased proinflammatory cytokines, endothelial dysfunction, altered glucose metabolism, elevated homocysteine, oxidative stress, and vitamin D metabolism disorders.
• Significant dietary changes in the mid-19th century, altering the omega-6 to omega-3 fatty acid ratio, are linked to common underlying factors.
• This dietary shift induced metabolic changes, increasing pro-inflammatory mediators and modulating signaling pathways relevant to both CVD and DD.

Conclusions:

• Common metabolic pathways and risk factors link cardiovascular disease and depressive disorders.
• Historical dietary shifts, particularly concerning omega-6 and omega-3 fatty acids, are implicated as a significant contributing factor.
• Understanding these shared mechanisms may offer new avenues for prevention and treatment of both conditions.
