Ischemic Heart Disease and the Western World

Ischemic heart disease is the proper medical term for reduced blood flow to the heart – it is ultimately caused by hardened or blocked arteries, and it is the number one cause of death in most western countries.

From the time people are very young, as young as five years old, they can start developing tissue deposits, called plaque, in the lining of their arteries. For many people, these deposits never cause trouble. For others, the deposits can grow, harden, and eventually cause death. The growth of these tissues is called arteriosclerosis.

As these tissues grow, the arteries will enlarge some to try and accommodate blood flow. However, if the blob of plaque ruptures, the particles clog blood passages causing a heart attack or stroke, in the worst cases.

"Please, Pass On The Fats"

Scientists know what causes ischemic heart disease: a fatty diet, inaction, and smoking. While smoking is certainly not limited to rich countries, a fatty diet and inaction are luxuries of middle- and upper-class populations.

In Europe and the United States, calories are cheap and plentiful. For an hour’s wage, a person can buy a meal containing a pound of meat. However, in some countries, a pound of meat is a treat to be divided within one family once a month. No doctor recommends either extreme of poor or rich food, but rather, everyone needs a healthy, balanced, but lean diet to prevent ischemic heart disease.

However, some doctors have an idea about using peer pressure to make westerners make themselves healthier. Thirty years ago, few Americans wore seatbelts. And many more smoked cigarettes than do now. Laws played a part in changing behavior, but in both of these cases, peer pressure really started the trend. And many scientists, nutritionists, and activists, worried about ischemic heart disease, are trying to repeat the trend for healthier diets.

And this power of healthy suggestion seems to be working on restaurants. Especially since 2004, fast food chains have started to offer healthier menu choices such as yogurt, salads, and fruit. Many restaurants now print some nutrition information on their menus and offer specifically “heart-smart” recipes.

But the question is will people take advantage of healthier menus, city recreation departments, and fresh vegetables at the grocery store? So far, it does not seem so. Some scientists predict that 75% of all Americans will be overweight by 2008. Yet extra weight and the bad diet and inactivity that usually accompany it are causing an epidemic of ischemic heart disease.

Obesity and Heart Disease ; Are They Related in Some Ways ?

Many medical professionals believed that obesity and heart disease were only related in an indirect sense. They attributed the major risk factors for heart disease (such as hypertension, high cholesterol, and even arteriosclerosis) to the degree of the obesity of the person involved. While obesity is a contributing factor for many of these conditions, studies are now indicating a more direct link between obesity and heart disease.

A More Direct Link?

Recent longitudinal studies indicate that while obesity can affect a number of risk factors for heart disease, the two are also directly related in that obesity can be a predictive indicator of heart disease. In a fourteen year study, it was indicated that middle-aged women with a BMI index of greater than twenty-three, but less than twenty-five still had an approximate 50% increase in the risk of both fatal and non-fatal coronary heart disease. This indicates a clear, direct connection between obesity and heart disease.

Another factor that may connect severe obesity and heart disease more directly is that of abnormalities in the left ventricular mass and function of the heart. While in the majority of cases, these abnormalities are seen in the presence of both hypertension and obesity, there are recorded causes where these abnormalities are seen without hypertension being apparent. In such cases, the only condition that appears to affect the condition of the heart is severe obesity. This information indicates that obesity and heart disease are intricately linked and can definitely lead to congestive heart failure.

Treatment Choices for Obesity and Heart Disease

Since a connection, either direct or indirect, has long been established between obesity and heart disease, the medical profession has developed a number of avenues over the years to combat these two related problems.

In certain patients with congestive heart failure, for instance, sodium restriction and even a small reduction in weight may dramatically improve the function of the heart and lead to a reduction in the risk of heart disease. In fact, a number of studies have indicated that a drastic weight loss, such as after gastro-intestinal surgery, greatly decreases the occurrence of both heart disease and insulin based diabetes.

There are, of course, any number of ways to treat both obesity and heart disease. These can include changes in diet and exercise practices, medication, and sometimes even surgery. Only you and your doctor can decide what choice is best for you. Whatever method is chosen, the connection between obesity and heart disease is becoming clearer everyday.
