Global average left ventricular end-diastolic wall thickness (GT) relates non-linearly to LVM and EDV. We hypothesized that if GT is independent of EDV in health, then GT will be an ideal measure of post-intervention change in left ventricular hypertrophy. Methods: GT [mm] was calculated using LVM and EDV by cardiovascular magnetic resonance as previously validated. The correlation between GT and EDV was evaluated in healthy volunteers. Change in GT following intervention was evaluated for aortic s","pubDate":"2026-11-02","url":"https://www.medrxiv.org/content/10.64898/2026.11.01.26367004v1?rss=1"},"indexado":"2026-11-03T09:02:53.279Z"}}
