New Study Suggests Waist Circumference as Key Indicator of Heart Disease Risk
A recent study presented at the American Heart Association's scientific conference challenges the traditional reliance on Body Mass Index (BMI) as a predictor of heart disease risk. The research, which involved approximately 2,000 adults over a seven-year period, found that central obesity measures, such as waist circumference and waist-to-height ratio, are more accurate indicators of heart disease risk than BMI. The study highlights that individuals with normal BMI can still be at significant cardiac risk if they have fat accumulation in the abdominal area. This visceral fat, which surrounds vital organs, is metabolically active and contributes to conditions like insulin resistance and high blood pressure, increasing the risk of heart failure. The study also noted that high levels of C-reactive protein (CRP), an inflammatory marker, were associated with reduced survival without heart failure.
