Researchers from the Harvard School of Public Health and Harvard Medical School, measured the diet quality of 4098 total participants who had survived an initial myocardial infarction (MI) during the study analysis period. Participants completed pre- and post-MI food questionnaires, with diet quality measured by means of the Alternative Healthy Eating (AHE) Index 2010, a measurement frequently utilized to assess diets intended to combat major chronic diseases.
The researchers found that of the 1133 total confirmed all cause deaths, those with higher scores on the AHE Index had lower overall mortality rates. When the total results were pooled, the adjusted hazard ratio (HR) was 0.76 for all-cause mortality and 0.73 for cardiovascular mortality, respectively. Those with the greater AHE Index scores (from pre- to post-MI) , had lower all-cause mortality (HR, 0.71) and even significantly lower cardiovascular mortality (HR, 0.60) comparatively.
Coronary heart disease (CHD) continues to be the leading cause of death worldwide, even though it can largely be prevented through a healthful lifestyle. According to a CDC Press Release, Sept. 3, of the 1 in 3 deaths in the US each year caused by heart disease and stroke, at least 200,000 of these could have been prevented through changes in health habits, such as ceasing to smoke and more physical activity.
A higher quality diet that is heart-healthy diet should include more fruits and vegetables and less sodium and Trans fat. There is increased evidence that the Mediterranean diet is the consistent dietary model beneficial to the prevention of major chronic diseases, including fatal and nonfatal CHD, as well as all-cause mortality.
