Insights
The Mediterranean diet is recommended for secondary prevention of coronary heart disease (CHD). This dietary pattern effectively reduces cardiac events and improves survival in patients with existing heart conditions.
Area of Science:
- Cardiovascular Medicine
- Nutritional Science
- Preventive Cardiology
Background:
- Coronary heart disease (CHD) poses significant mortality risks, primarily from sudden cardiac death (SCD) and chronic heart failure (CHF).
- Recurrent cardiac events are driven by coronary thrombosis, linked to atherosclerotic plaque instability and lipid content.
- Preventive strategies aim to mitigate thrombosis, ventricular arrhythmias, and left ventricular dysfunction.
Purpose of the Study:
- To review current knowledge on the Mediterranean diet's role in secondary prevention of CHD.
- To evaluate the Mediterranean diet's efficacy compared to other interventions.
Main Methods:
- Literature review of studies on adult coronary patients at high risk of cardiac death.
- Analysis of existing research on dietary patterns and CHD outcomes.
Main Results:
- The Mediterranean diet is recognized for its effectiveness in secondary CHD prevention.
- Unlike some pharmacological approaches, the Mediterranean diet demonstrates a significant impact on patient survival.
- It addresses key pathological mechanisms including coronary atherosclerosis, thrombosis, and risk of fatal complications.
Conclusions:
- The traditional Mediterranean diet is a proven strategy for reducing coronary atherosclerosis and thrombosis.
- It effectively lowers the risk of fatal outcomes such as sudden cardiac death and heart failure in CHD patients.
Objective:
To summarise our present knowledge on the Mediterranean diet in secondary prevention of CHD.
Design:
Review of literature.
Setting:
Adult coronary patients.
Subjects:
CHD patients at high risk of cardiac death.
Results:
The two main causes of death in these patients are sudden cardiac death (SCD) and chronic heart failure (CHF). The main mechanism underlying recurrent cardiac events is coronary thrombosis resulting from atherosclerotic plaque erosion or ulceration. The occurrence of thrombosis is usually associated with plaque weakness in relation to high lipid content of the lesion where cholesterol only represents a very small part compared with other lipids (i.e. fatty acids). Thus, the three main aims of the preventive strategy are to prevent coronary thrombosis, malignant ventricular arrhythmia and the development of left ventricular dysfunction (and CHF) and finally to minimise the risk of plaque erosion and ulceration. There is now a consensus about recommending the Mediterranean diet pattern for the secondary prevention of CHD because no other dietary pattern has been successfully tested so far in these patients. The most important aspect, in contrast with the pharmacological prevention of CHD (including cholesterol lowering), is that the Mediterranean diet results in a striking effect on survival.
Conclusions:
The traditional Mediterranean diet is effective in reducing both coronary atherosclerosis/thrombosis and the risk of fatal complications such as SCD and heart failure.
