Description
Marco Guglielmo and co-authors test a coupling measure between the heart's upper and lower left chambers as a predictor in weak-heart patients in a 2026 study. The index divides left atrial by left ventricular volume at filling, both read from cardiac MRI. Patients came from a multicenter registry of people with ejection fraction under fifty percent.
Statistical models weighed the index against death, and against death or heart-failure events, with competing-risk methods for heart failure alone. Time-based accuracy analysis set cutoffs for three-year outcomes. The premise is that a stiff, overfilled atrium coupled to a failing ventricle marks advanced disease better than either chamber alone. The authors report the index carries prognostic value in this reduced-function population, adding a simple ratio to the MRI report.
