Left Atrial to Ventricular Volume Ratio: A Novel Imaging Biomarker Enhancing Detection of Atrial Cardiopathy and Stroke Risk

By MedXY 06/28/2026

The left atrial to ventricular volume ratio (LA:LV ratio) emerges as a superior marker over left atrial volume index (LAVi) for atrial cardiopathy, showing stronger association with ischemic stroke risk, cognitive decline, and atrial fibrillation detection in large cohorts.

Persistent Fibroblast Activation Predicts Heart Failure Progression: [68Ga]FAPI-46 PET/MRI Reveals Distinct Patterns in Ischemic and Nonischemic Cardiomyopathy

By MedXY 04/15/2026

A prospective case-control study demonstrates that myocardial fibroblast activation persists in heart failure patients and follows distinct spatial patterns depending on etiology. Using [68Ga]FAPI-46 PET/MRI, researchers found that higher baseline uptake predicts worse outcomes, suggesting potential for risk stratification and targeted antifibrotic therapy development.

Sex-Specific Risk Stratification in Aortic Regurgitation: Moving Beyond One-Size-Fits-All Thresholds

By MedXY 03/21/2026

New evidence suggests that current guidelines for aortic regurgitation may overlook sex-specific risks. A recent study proposes lower surgical thresholds for both sexes and distinct volumetric cutoffs (40 mL/m² for women, 45 mL/m² for men) to improve survival outcomes and precision in cardiac care.
