Clinical and pathological characteristics of immune checkpoint inhibitor-related fulminant myocarditis.

The advent of immune checkpoint inhibitors (ICIs) has significantly improved cancer treatment. With the increasing use of ICIs, ICI-related myocarditis has been recognized. However, an evidence-based therapeutic strategy has not been established because of the limited knowledge on ICI-related myocarditis.

Right Ventricular to Pulmonary Artery Uncoupling Is Associated With Impaired Exercise Capacity in Patients With Transthyretin Cardiac Amyloidosis.

Background: Exercise capacity is related to mortality and morbidity in heart failure (HF) patients. Determinants of exercise capacity in transthyretin cardiac amyloidosis (ATTR-CA) have not been established.

Methods And Results: This single-center study retrospectively evaluated ATTR-CA patients and patients with non-amyloidosis HF with preserved/mildly reduced ejection fraction (HFpEF/HFmrEF) (n=32 and n=51, respectively).

Effectiveness of Vericiguat on right ventricle to pulmonary artery uncoupling associated with heart failure with reduced ejection fraction.

Backgrounds: A soluble guanylyl cyclase stimulator vericiguat has been shown to reduce cardiovascular mortality or hospitalization for heart failure in patients with worsening heart failure in the VICTORIA study. However, little is known about the effects of vericiguat on biventricular structure and function.

Methods And Results: A retrospective analysis of 63 consecutive patients with heart failure with reduced ejection fraction (HFrEF) who were treated with vericiguat was performed.
