Differential Biventricular Strain Recovery With Selective Fibrosis Biomarker Regression After Sleeve Gastrectomy: A Prospective CMR Feature-Tracking Study.
Heart function recovers quickly after weight-loss surgery while cardiac scarring improves more slowly, guiding timing of cardiovascular follow-up and comparing surgical versus medical options.
This first-of-kind prospective study using both cardiac MRI (biventricular strain assessment) and fibrosis biomarkers to characterize cardiac recovery after sleeve gastrectomy demonstrates that obesity-induced cardiac damage reverses along distinct timelines—functional strain recovers rapidly while fibrosis biomarkers show more selective regression. The dissociation between functional and structural recovery has direct implications for timing of post-bariatric cardiovascular surveillance and the complementary roles of bariatric surgery versus pharmacological approaches for cardiac risk reduction.
