BackgroundGalectin-3 is a well-established biomarker on the predictor of cardiovascular events in patients with heart failure. Its pathophysiologic association with inflammation, cell proliferation, and fibrogenesis may implicate serum galectin-3 as a predictor of clinical outcomes in coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES).

Breathing polluted air—even at levels considered “safe”—may quietly damage your heart. A new study using advanced MRI scans found that people exposed to more air pollution showed early signs of scarring in their heart muscle, which can lead to heart failure over time. This damage showed up in both healthy individuals and people with heart conditions, and was especially noticeable in women, smokers, and those with high blood pressure.

ABSTRACT Pulmonary vein isolation (PVI) alone has limited success in treating persistent atrial fibrillation (AF), prompting the use of adjunctive strategies like vein of Marshall (VOM) ethanol infusion to improve outcomes. This step-by-step guide outlines a standardized approach for VOM ethanol infusion, including venous access, coronary sinus cannulation, VOM identification, and ethanol infusion via an over-the-wire balloon catheter.

ABSTRACT Background Atrial fibrillation (AF) is the most common cardiac arrhythmia, associated with significant morbidity, including increased risks of stroke, heart failure, and mortality. While catheter ablation is an effective rhythm control strategy, high recurrence rates postprocedure remain a major clinical challenge. Inflammation plays a key role in AF pathogenesis, and anti-inflammatory therapies have emerged as potential adjunctive treatments to reduce recurrence.
