Obese children show to have a blood vessel abnormality comparable to what doctor’s see in much older adults with cardiovascular disease, a study has found. Lead author Dr. Kevin Harris, a cardiology fellow at B.C. Children's Hospital, said tests in a group of fat children showed the aorta the major artery from the heart had lost normal suppleness, as if the age process has been accelerated in the blood vessel. "We were astounded to find that these obese children already have stiff blood vessels," said Harris. "Aortic rigidity is an early pointer of cardiovascular disease in obese children." The aorta, the major artery in the body, carries oxygen rich blood from the heart to all the further arteries.
"The normal aorta has elastic character that buffer the flow of blood. When that elasticity is lost, aortic rigidity results a sign of developing cardiovascular disease," said Harris, adding that aortic stiffness in adults is linked with heart attacks and stroke that can result in premature death. He said the childhood fatness rate has risen dramatically over the last 30 years, foremost to predictions that life expectation in Canada is set to decline for the initial time in the country's history. "I think that underscores the scale of the problem," Harris said. To conduct the study, the B.C. researchers assess the heart and blood vessels of 63 obese children and 55 normal weight children using echocardiography, a type of ultrasound.
Blood pressure, cholesterol and body major index also were measured in all the children, who had a denote age of 13. While the obese children had usual cholesterol levels, their blood pressure was slightly elevated and ultrasound of the heart showed arterial health was previously compromised. "I think it's kind of an early pointer of cardiovascular disease and it's important because we need to recognize that obesity is touching children very early on," said Harris, who was to present his conclusion Monday at the Canadian Cardiovascular Congress in Montreal. Toronto cardiologist Dr. Beth Abramson, a spokeswoman for the Heart and caress Foundation, said it is alarming to see change in the performance of the heart and blood vessels in heavy children.
