According to a recent study, fatty started people gathered in the heart of pre-diabetes before diabetes or heart disease symptoms appear. Researchers from the University of Texas Southwestern Medical Center found a gathering of fat using simple drawing techniques that can be a new screening tool for people who are at risk of contracting the disease Diabetes and heart disease.
Previous studies have shown that the accumulation of fat in the heart of people with diabetes and heart failure, but they do not know whether the fat is piled it happened before or after diabetes occurs. The challenge is to find a way to obtain static images of human heart are usually in constant motion.
Senior author Dr. Lidia Szczepaniak said that the heart rate, respiration and magnetic resonance imaging (MRI) is highly sensitive in motion, so they must find a way electronically freeze the image of the heart. In the journal Circulation: September 4, Szczepaniak and her team explain the technique using an MRI system with the addition of computer software that converts signals from the heart of the movement into the picture is not moving.
Using this method, they tested the cardiac images of lean and overweight (obese) with normal blood sugar, obese people with a new show abnrmal blood sugar, and overweight people with type 2 diabetes. In addition to studying the deposition of fat occurs before diabetes, the researchers also found that people with abnormal glucose metabolism has a fat content was significantly higher in heart than people with normal blood sugar, regardless of weight.
Although the amount of fats in the heart are not related to the amount of fats in the blood stream or heart, it is in relation with total fat of the abdomen. According to the researchers, accumulation of fat in heart cells is important to be identified and prevented because heart cells can not be replaced when dead. Excess fat in the heart slowly kill the organ, according to them.
