Men with metabolic syndrome who also have a waist size of 94 cm or larger have a 30% chance of silent heart disease, compared to 20% for those without large waists, according to the study. This finding is from the abstract summary - full study details were not available
Scientific Claim
Among adult males with metabolic syndrome defined by the National Cholesterol Education Program criteria, those with a waist circumference of 94 cm or greater have a higher prevalence of silent coronary artery disease (30% vs. 20%; P=0.026) compared to those without high waist circumference.
Original Statement
“among patients with metabolic syndrome defined by NCEP-R, those with a high WC as a defining component of metabolic syndrome had a higher prevalence of silent CAD (30% vs. 20%; P=0.026).”
