Dietary patterns, Mediterranean diet, and cardiovascular disease

Area of Science:

• Nutritional Science
• Cardiovascular Medicine
• Preventive Cardiology

Background:

• Cardiovascular disease (CVD) remains a leading cause of mortality worldwide.
• Dietary patterns play a crucial role in cardiovascular health.
• The Mediterranean diet (MeDiet) has been associated with numerous health benefits.

Purpose of the Study:

• To review existing evidence on the association between adherence to the MeDiet and CVD risk.
• To update findings from the latest meta-analysis on MeDiet and cardiovascular outcomes.
• To evaluate the effectiveness of the MeDiet for primary and secondary cardiovascular prevention.

Main Methods:

• Systematic review of scientific literature.
• Meta-analysis of randomized controlled trials and observational cohort studies.
• Inclusion of data from landmark trials like PREvención con DIeta MEDiterránea and Lyon Diet Heart Study.

Main Results:

• The PREvención con DIeta MEDiterránea trial demonstrated the beneficial role of MeDiet in primary cardiovascular prevention.
• Combined analysis of key trials showed a 38% relative reduction in CVD events with MeDiet intervention.
• New observational studies indicated a significant reduction in cardiovascular events with increased MeDiet adherence (0.87; 95% CI: 0.85-0.90).

Conclusions:

• Consistent evidence supports the Mediterranean dietary pattern as an effective strategy for CVD prevention.
• Promoting the MeDiet is a feasible public health approach to reduce cardiovascular disease burden.
• The MeDiet is a valuable tool for both primary and secondary cardiovascular prevention.
