A new study shows a high risk of death or hospitalization from heart disease, and a person with relatively fat hidden in muscles and around it faces the association that lasts regardless of the body trout index (BMI). Masu.
The survey results emphasize THe is insufficient BMI as a heart health marker A potential dangerous factor of cardiovascular disease that guarantees further research.
“By knowing that muscular fat increases the risk of heart disease, you can get another way to identify people with high risk, regardless of the body mass index.” say Viviny Taketi, a co -author of Brigam and Women’s Hospital Heart Stress Institute.
The authors have stated that the effects of fat muscles on the health of the fat muscles remain well, but they are related to insulin resistance and type 2 diabetes. They say this is the most thorough study on the effects of fat muscle on heart disease so far.
In addition to illuminating the link, this study emphasizes metric restrictions such as BMI when evaluating the risk of heart disease universally.
“Obesity is now one of the largest global threats to the health of cardiovascular health, but the body trout index -the main indicators for defining obesity and threshold for intervening are the discussions of cardiovascular prognosis. It is still a defective marker. ” I will explain Takey
“This is especially true for women who reflect the” benign “type of fat, especially. “
Of course, everyone needs body fat, such as a small sediment embedded in the skeletal muscle fibers called an intercient fat tissue (Imat).
Muscular fat is present in most muscles, but the amount varies from person to person and tends to increase with age. Too much muscle fat may accumulate in a state known as skeletal muscles, fat infiltration or fascia.
Previous research shows high -level IMATs associated Insulin resistance and Metabolic syndromeSimilarly Loss of strength and Mobility problem。 However, many IMAT remains unknown, including how it affects the health of cardiovascular.
Tachetti and her colleagues are the quality of the muscles Coronary artery micro -blood vascular dysfunction (CMD) -The small blood vessels that can withstand the heart have been damaged, and other cardiovascular disorders.
“In our research, we analyze muscles and various kinds of fat, and how the physical composition affects small blood vessels or” micro -circulation “, and the risk of future death in the future. I understand. ” say。
This study was involved in 669 subjects. All patients were brigams and women’s hospitals with chest pain or shortness of breath, but no signs of obstructive coronary diseases. About 70 % are women, 46 % are non -white, the average age is 63 years old, and the author Report。
Researchers looked at the heart of each patient with a heart proton -release fault shooting/computer fault shooting (PET/CT) scan. In addition, the body composition was revealed using a CT scan, and the amount and position of fat and muscle were measured.
Their analysis included the measurement called Fatal muscle rate -The ratio of interchangeable, skeletal muscles and interconnected fat.
Researchers have tracked subjects for about six years and recorded death or hospitalization due to heart attacks and heart failure.
Research has discovered that patients with the rise of the IMAT level are likely to suffer from CMD, and have been discovered that the risk of death or hospitalization due to heart disease is high.
Regardless of the BMI or other known risk factors, if the fatal muscle drawing is 1 %, the CMD risk is 2 % higher, and the risk of major side -blooded events is 7 % higher.
This study suggests that the risk of death, heart failure, and heart failure is particularly dangerous for patients with excessive IMAT and CMD evidence.
Researchers have reported that the risk of muscle muscle muscles is lower. Storing fat in other places in the body, as under the skin, did not increase the risk.
“Compared to subcutaneous fat, fat stored in muscles may contribute to changes in inflammation and glucose metabolism. say。 “Next, these chronic in humiliation can cause damage to blood vessels, which are supplying the heart and myocardial itself.”
As the author acknowledges, this study has some remarkable restrictions. Adjusted editing。
In future research, she says that she needs to dig deeper into a link between fat and heart disease, and investigates how to save her life using this information.
