Abdominal Fat, Not BMI, Linked to Harmful Heart Remodeling in MRI Study

High waist-to-hip ratios correlated with concentric hypertrophy on cardiac MRI in 2,244 adults.

Overview

  • Effects were strongest in men, with pronounced changes in the right ventricle and additional subtle tissue alterations visible only with advanced imaging.
  • Associations between abdominal obesity and adverse cardiac structure remained after adjusting for hypertension, smoking, diabetes, and cholesterol.
  • BMI more often aligned with enlarged heart chambers, whereas waist-to-hip ratio tracked with thicker myocardium and smaller chamber volumes.
  • Participants were ages 46 to 78 without known cardiovascular disease from the Hamburg City Health Study, and the findings were presented at RSNA 2025.
  • Researchers recommend routine waist-to-hip measurement and early steps to limit visceral fat; WHO flags ratios above 0.90 for men and 0.85 for women.
