Global thickness for accurate and precise evaluation of post-intervention remodelling in left ventricular hypertrophy

Global average left ventricular end-diastolic wall thickness (GT) is negligibly linked to end-diastolic volume (EDV) in healthy volunteers (n=4461), enabling accurate tracking of post-intervention hypertrophy remodeling.

• Why it matters: Cardiovascular interventions can alter both left ventricular mass and EDV, but the net effect on wall thickness has been hard to measure precisely using mass/volume metrics.
• What they did: GT (mm) was computed from LVM and EDV using cardiovascular magnetic resonance, then tested for EDV dependence in healthy volunteers and for change after valve replacement, antihypertensive treatment, or forced detraining.
• The result: After intervention, GT changed in all conditions (p≤0.02) while LVM/EDV did not, with mean GT shifts of -1.75±0.13 mm (aortic stenosis), -0.66±0.08 mm (hypertension), -0.29±0.09 mm (athletes), and +0.50±0.11 mm (aortic regurgitation).
