Redefining Severity in Tricuspid Regurgitation: Why CMR-Derived Regurgitant Fraction and Liver Mapping Are the New Prognostic Gold Standards

A landmark study in Circulation reveals that CMR-quantified tricuspid regurgitant fraction (TRF) ≥20% significantly increases mortality risk, while liver extracellular volume (L-ECV) mapping provides a novel, potent biomarker for systemic congestion and right heart failure outcomes.

A Unified High-Sensitivity Cardiac Troponin I Threshold of 80 ng/L for Risk Stratification in Wild-Type Transthyretin Amyloid Cardiomyopathy

This multicenter study identifies high-sensitivity cardiac troponin I (hs-cTnI) as a potent, independent predictor of mortality in wild-type transthyretin amyloid cardiomyopathy. A universal threshold of 80 ng/L, integrated with natriuretic peptides, provides a robust staging system across multiple assay platforms.

Vericiguat in Heart Failure with Reduced Ejection Fraction: Evidence from Pooled Analyses of VICTORIA and VICTOR Trials

Pooled data from VICTORIA and VICTOR trials demonstrate that vericiguat significantly reduces cardiovascular death and heart failure hospitalization in a wide spectrum of patients with heart failure and reduced ejection fraction, including those without recent worsening, supporting its role as an adjunctive therapy.

Transthyretin Cardiac Amyloidosis in Older Black and Hispanic Patients with Heart Failure: Prevalence, Genetics, and Clinical Implications

A prospective study reveals transthyretin cardiac amyloidosis (ATTR-CA) affects a significant proportion of older Black patients with heart failure, especially men over 75, with nearly half linked to the V142I genetic variant. Hispanic prevalence is lower but still notable.

Vericiguat in Stable HFrEF Patients: No Improvement in Composite Endpoint but Significant Reduction in Cardiovascular and All-Cause Mortality – Insights from the VICTOR Trial

The VICTOR trial in stable HFrEF patients shows vericiguat does not significantly reduce the composite of cardiovascular death or heart failure hospitalization but lowers cardiovascular and all-cause mortality, highlighting its potential for mortality risk reduction.
