MONTREAL – people who have survived a heart attack are at an increased risk of new incident they have an extra weight in the abdomen, warns a study published in the European Journal of Preventive Cardiology.

Previous studies had demonstrated that abdominal obesity was a significant risk factor for a first myocardial infarction, but no association had been documented between obesity and the risk of subsequent heart attack.

“In fact, it is a little bit obvious,” said cardiologist Martin Juneau of the Montreal heart Institute. When the authors say that it had never been studied, that is like saying that no one has ever studied the effect of smoking after a heart attack. It is obvious that if it has an effect to cause a heart attack, then it will have an effect to cause other. So, for me, it has always been a no-brainer that abdominal obesity is a high risk situation that, even today, is a little bit under-estimated or misunderstood.”

Researchers at the prestigious Karolinska Institute in Sweden, followed more than 22 000 patients after their first myocardial infarction, in order to investigate the association between abdominal obesity and cardiovascular events secondary. They are specifically interested in the events caused by clogged arteries, such as heart attacks (fatal or non-fatal) and stroke (STROKE).

Most of the subjects – 78% of men and 90 % of women – had abdominal obesity (a waist circumference of 94 centimetres for men and 80 centimetres for women).

Abdominal obesity has been associated with heart attacks and STROKE, irrespective of factors such as smoking, diabetes, hypertension, and body mass index. The tour size was a marker for the more important side-events, general obesity.

The author of the study, Dr. Hanieh Mohammadi, warns in a press release that the risk of a secondary event was higher in patients with abdominal obesity, even if they were taking medication to treat the health problems that are associated with it.

“One of the authors said that once they have made their stroke, we treat all the consequences of abdominal obesity: to treat blood glucose that is elevated with insulin resistance, to treat high blood pressure, treating the high cholesterol… But to me, it doesn’t surprise me at all because we had not treated the cause, then treat it with pills!” exclaimed Dr. Juneau.

“To give you an idea, in a young woman, say, 30 to 55 years of age, [abdominal obesity] increases the risk [of heart attack] by three.”

Plaques destabilized

The type of fat cells found in the visceral organs secretes inflammatory factors that will enter in the bloodstream and destabilize the atherosclerotic plaques at the level of the coronary arteries, explained Dr. Juneau, in addition to disturb the cerebral circulation and cause more than early dementia.

“It affects the entire system, this grease-there, he said. The inflammation will contribute to the weakening of the atherosclerotic plaques on the coronary disease that will cause blood clots. What you don’t want to, these are lesions on your coronary inflamed and friable. You want them to be stabilized. And to stabilize them, it takes a power anti-inflammatory, such as mediterranean or vegetarian, and all the ingredients of a [diet] mediterranean fruits, vegetables, whole grains, omega-3 – it’s coming to stabilize the plates because it is very anti-inflammatory.”

Losing weight is not easy, ” said Dr Juneau, and this is not by multiplying the number of crunches you will get rid of our abdominal fat. The only way to solve the problem is to change our habits of life, starting with diet and physical activity.

“If you don’t change your [power], if you just take pills, the inflammation is there and the risk is there, he said. It reinforces the message for clinicians […] that even if it was treated with pills pressure, cholesterol and diabetes, if it has not resolved abdominal obesity, it has not settled much. This, it is fundamental.”
