A scientific study stated that “abdominal obesity” is associated with more harmful changes in the structure of the heart compared to a general increase in body weight, especially in men. The study indicated that these cardiac changes can gradually develop into heart failure if timely intervention is not carried out. Researchers revealed at the meeting of the Radiological Society of North America that the accumulation of fat in the abdominal area is linked to a pathological pattern of cardiac remodeling called concentric hypertrophy, where the thickness of the heart muscle increases without an increase in its overall size, leading to a shrinkage of the size of the heart chambers and a decrease in the amount of blood it pumps. The study team explained that this problem appears to be more severe in men than in women, highlighting the importance of focusing on abdominal obesity, and not just general weight, when assessing cardiac risks. Using advanced cardiac magnetic resonance imaging, the study showed that abdominal obesity, measured by the waist-to-hip ratio, was associated with a reduced ability of the heart to relax between contractions, a factor known to be associated with later heart failure. High prevalence of obesity. The results revealed that general obesity, which is measured by the body mass index, is often associated with the enlargement of the heart chambers, while abdominal obesity is associated with the thickness of the heart muscle and a decrease in the size of its internal chambers. The study showed that these structural changes were more visible in the right ventricle in men, which is the part responsible for pumping blood to the lungs, which could indicate that abdominal fat affects breathing and lung pressure, causing premature cardiac stress in them. Data on 2,244 adults between 46 and 78 years of age, without known heart disease, were studied within the framework of the long-term Hamburg City Health Study in Germany. The analysis revealed that 69% of men and 56% of women were overweight or obese according to the body mass index, while the percentage of obesity increased significantly when waist circumference was based on the hip, as the rate of abdominal obesity in men reached 91% compared to 64% in women, according to World Health Organization standards. The researchers confirmed that abdominal obesity reflects the accumulation of visceral fat located deep around the internal organs, and it is the most dangerous type of fat for the heart compared to superficial fat or general excess weight. The study went on to document the occurrence of subtle changes in heart tissue in men suffering from obesity, which are changes that can only be detected with the help of advanced imaging techniques, indicating early stress on the heart muscle even before tangible symptoms appear or a formal disease diagnosis. The analyzes showed that this negative effect of obesity on the heart remained constant even after other heart risk factors such as high blood pressure, smoking, diabetes and cholesterol levels were taken into account, confirming that obesity, especially abdominal obesity, represents an independent factor in the deterioration of heart health. The study’s lead researcher, Jennifer Early, who is also a radiologist at the University Medical Center Hamburg-Eppendorf in Germany, sent a clear message that abdominal obesity can be more dangerous than many people think, and that its effect on the heart goes beyond just weight gain. Early emphasized that focusing on overall weight reduction may not be the ideal solution for everyone, and that health interventions should be primarily aimed at preventing the accumulation of fat in the abdominal area through regular physical activity, following a balanced diet, and resorting to medical intervention if necessary. Early intervention: The study pointed out that differences between the sexes may result from the occurrence of abdominal obesity earlier and more severely in men, or from the potential protective role of estrogen in women, with the need for additional studies to confirm these hypotheses. The study goes on to encourage individuals to use simple self-tools to monitor their heart health, emphasizing that measuring the waist-to-hip ratio can be done by anyone at home with a tape measure, by dividing the waist circumference at the narrowest area by the hip circumference at the widest area. She pointed out that a ratio of more than 0.90 in men and 0.85 in women is indicative of abdominal obesity, and is associated with a high risk of heart disease according to World Health Organization standards. The researchers also pointed out that awareness of this value can help with early intervention and lifestyle change before serious health stages are reached. The study called on doctors to be more aware of the link between abdominal obesity and structural heart changes, and stressed that when radiologists notice a pattern of myocardial hypertrophy with a decrease in the size of its chambers, they should consider obesity as a possible cause, and not just consider it a consequence of cardiomyopathy, high blood pressure or other diseases. Researcher Early explained that the clinical connection between the appearance of the heart on MRI and obesity can contribute to early detection and improve opportunities for treatment and prevention. The study also demonstrated that abdominal obesity should be treated as an important independent risk factor for heart disease, rather than simply a consequence of being overweight. The findings call for doctors and patients to begin using simple, continuous surveillance mechanisms to monitor abdominal fat, while promoting awareness of its specific risks compared to general obesity. The findings also reinforced the call for public health policies specifically targeting abdominal obesity, given its increasing prevalence among middle-aged men. Traditional measures: The results also indicated the importance of community interventions and health practices that help to reduce the risk of abdominal obesity, including spreading a culture of physical activity, supporting healthy environments inside and outside work, providing practical and not expensive nutrition programs, in addition to improving the role of primary care centers in early detection. The study acknowledged that weight gain may not be the same risk across all parts of the body, and that where fat accumulates plays a fundamental role in affecting heart and overall health. The study offered a new perspective on obesity risk that goes beyond traditional measures such as weight and body mass index, and called for the inclusion of abdominal obesity measurements in future medical guidelines for cardiac risk assessment. The results confirmed that this transformation will allow early and targeted diagnosis, and improve the effectiveness of plans to prevent heart disease before it reaches stages that are difficult to treat. She also warned that investing in early measurement tools could save healthcare systems long-term costs from treating advanced heart disease. The study concluded with the researchers emphasizing that abdominal obesity as an important medical indicator should not be treated as less important than blood pressure or cholesterol levels, and that understanding the risks associated with it is an essential step in protecting heart health in men and women, with the fact that men are more affected by these risks, and that early defense is the best line of defense against the development of heart failure that can later lead to heart failure.
