Overweight or obese has long been known as a risk factor for heart disease. Doctors often take into account in assessing a person’s risk of obesity with heart disease.
Heart patients with greater waist circumference of 35 inches for women or 40 inches in men have a higher risk of dying 70 percent faster.
Obesity among them can be known by measuring body mass index (BMI). This is a simple measurement value by dividing the weight by the size of high altitude. The higher the BMI person, the more likely fall into the category of obesity.
Numerous studies have indicated, the highest score of BMI associated with a lower risk of dying from heart disease or chronic illness. This is a mysterious phenomenon known as the “obesity paradox” term
According to expert analysis published in the Journal of the American College of Cardiology, this paradox may be explained by the simple fact that BMI is not accurate enough to measure the risks associated with heart disease. waist size, experts say, can give a more precise guide for predicting the risk of death from heart attack patients at an early age or other consequences.
In a study by experts from the Mayo Clinic in Rochester, Minnesota, USA, patients with heart disease by waist size over 35 inches for women or 40 inches for men have a 70 percent risk to die earlier than their smaller waist coil. The size of the large waist circumference combined with high body mass index score increased risk even to death.
“More important than the other possibility is the distribution of fat,” says researcher Francisco Lopez-Jimenez, MD, a researcher who is also a cardiologist at the Mayo Clinic in Rochester.
“Recent research shows another evidence that BMI had many limitations in assessing the risk of heart disease,” said Jean-Pierre Despres, PhD, Director of Research at the Quebec Heart and Lung Institute of Laval University, Quebec.
“If you measure the body mass index, then it will assess how the body is not fat distribution,” said Despres, who wrote an editorial accompanying the research report.
“I’m not saying that BMI is not useful. We just need more than that. IMC is the total cholesterol in fat. We know that there is good cholesterol and bad cholesterol, there are good fats and bad fats.”
In addition, continued Despres, BMI also can not distinguish between fat and muscle. ”Heart patients who underwent less active lifestyle can be noted that a low BMI because they lose muscle mass,” he said. Heart patients who have active lifestyles can experience weight gain and increased BMI, and that adding lean muscle.
These findings also led to debate on how the body and the risk of heart disease. Several other studies indicate that those with the apple-shaped body with fat deposits in the abdominal area with a higher risk of heart disease than those whose body was pear-shaped. However, this theory was challenged by experts.
Lopez-Jimenez and his team analyzed data on 16,000 heart patients who participated in one of the four studies and cardiac rehabilitation program at Mayo Clinic. More than a third of registered patients died during the study, for periods ranging from six months to seven years.
Raised body mass index values associated with a 35 percent lower risk of death. However, having a large waist circumference plus the high value of body mass index increases the risk of double death.
Why belly fat is so bad? The researchers explain that belly fat is a sign of visceral fat and the fat that gathered around the organs in the abdomen or belly. These fats can lead to insulin resistance and increasing the amount of bad cholesterol and to stimulate inflammation.
“Genetic factors play a strong role in determining whether a personcan accumulate fat around the waist,” Despres said. He estimates that about 30 percent of the population tend to accumulate fat inunwanted places such.
