Obesity affects the structure and the function of the Heart muscle
Australian researchers verified that people suffering from obesity are exposed to changes in the structure of the Heart muscle which affect its proper functioning, even if they did not have any heart disease. These changes might lead to later fall in the heart.
Researchers from the Queens Land faculty of Medicine in Australia measured the speed and strength of the heart muscle stretching using updated version of Ultra Sound waves technology in 142 persons noting that none of them had any of Heart diseases, blood pressure or diabetes. Also none of them suffered from symptoms that prove that there is congestion in the muscle of the heart. The average age of the participants was 44 years old.
The participants were classified into four groups according to their weights. When comparing the heart muscle in people having appropriate weight with the heart muscle in people having morbid obesity it was verified that the blood pumping of the left ventricle of the heart in obese people plus its ability to relax between two pumps were obviously weaker. This complete relaxation allows the ventricle to be completely filled in blood before it pumps the blood to the rest of the body organs.
Dr. Thomas Marwick, who led the research team, said that this study shows the direct relationship between obesity level and the rate of dysfunction of the heart muscle apart from the other causative factors that may affect heart muscle functioning like high or low blood pressure.
The results of the participants' heart picturing before being exposed to ultrasound tests showed that the pumping power of the heart muscle in each one of them is normal which means that they do not suffer from heart failure. Nevertheless, the study concluded that the limited or little structural or functional changes caused in the heart muscle by obesity have effective relation to heart failure that can not be ignored.
