Omega 3 and Reduced Risk of Myocardial Infarction by Greg Post

Myocardial infarction is a technical term used to describe an irreversible injury to heart muscle. It is normally used as a synonym for a heart attack and will be so used in this essay. Myocardial infarction is normally related to progressive atherosclerosis (blockage of the arteries.) Essentially the heart is slowly starved of oxygen and stops functioning properly causing irreparable damage and even death.

It is no surprise that much of the developed world suffers from heart disease because of diet and other lifestyle habits. In the United States heart disease remains the number one killer among adults and demonstrates similar statistics in many other modern countries. The surprise comes in knowing that the majority of heart disease is avoidable yet educated people continue to ignore the dangers and promote lifestyles conducive to cardiac damage. Though many factors contribute to heart disease the current essay will focus on one, in two parts. First we will consider the relation of fish consumption and myocardial infarction. Secondly we will consider the effects of dietary supplementation with omega-3 and vitamin E for those who had previously survived a heart attack.

Fish consumption and heart disease has been a topic of innumerable studies. One research project combined data taken from several such studies including the Chicago Western Electric Study, the Zutphen, Rotterdam and Swedish studies and the Study of U.S. Physicians among others. The goal of this research was to examine the relationship between fish consumption and the 30-year risk of death from coronary disease.

The participants of the study included 1,822 men between the ages of forty and fifty-five who were free of cardiovascular disease. For the first ten years annual examinations were given and mailed questionnaires and/or telephone interviews were used for the next fifteen years. Death certificates were used to classify cause of death for each patient.

During the 30-years follow up there were a total of 430 deaths from cardiovascular disease with 293 due to myocardial infarctions. Of the latter 196 were sudden, 94 were non-sudden and the remaining three could not be classified as either. Almost all of the sudden deaths were caused by myocardial infarction.

Detailed dietary history was kept on each participant with daily fish consumption as the primary focus. Each participant was categorized into one of four groups. The first group reportedly consumed no fish. The second group consumed between one and seventeen grams of fish per day. The third and fourth groups measured consumption as eighteen to thirty-four grams per day and greater than thirty-four grams per day respectively.

Predictably the results demonstrated an inverse relationship between fish consumption and the occurrence of myocardial infarction. In particular the participants who ate at least 35 grams of fish per day had a 42% lower death rate from heart attack compared to those who ate no fish at all.
