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.

Hypertension-Related High-Risk Features May Identify Which Patients With Cryptogenic Stroke Benefit From Apixaban Instead of Aspirin

By MedXY 06/10/2026

An exploratory ARCADIA analysis suggests that patients with cryptogenic stroke and atrial cardiopathy without severe hypertension-related features may derive greater benefit from apixaban than aspirin, whereas those with high-risk hypertensive features may not.

The QTc Paradox: Why Prolonged QT Intervals May Predict Lower Recurrent Stroke Risk in Atrial Cardiopathy

By MedXY 02/27/2026

A secondary analysis of the ARCADIA trial reveals a surprising inverse relationship: prolonged QTc intervals were associated with a significantly reduced risk of recurrent stroke in patients with atrial cardiopathy, challenging existing paradigms from general population studies.

Apixaban Shows No Increased Risk of MRI-Detected Intracranial Hemorrhage Compared to Aspirin in Atrial Cardiopathy

By MedXY 02/05/2026

An exploratory analysis from the ARCADIA-MRI substudy reveals that apixaban carries a similar risk of incident intracranial hemorrhages, microbleeds, and superficial siderosis compared to aspirin in patients with atrial cardiopathy and cryptogenic stroke.
