Go behind the scenes with JACC as editor-in-chief Harlan M. Krumholz, MD, SM, FACC, talks about what 's caught his attention in the latest JACC issue on amyloid. In this paper by Sheikh et al, the authors did a pre-specified exploratory analysis from the HELIOS-B trial, evaluating vutrisiran in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). The study showed that vutrisiran helped preserve or improve functional capacity and quality of life over 30 months, with consistent benefits across both monotherapy and tefamidis-treated patients. Waterfall plots illustrated the full spectrum of individual patient responses, revealing meaningful improvements in many while underscoring variability in outcomes. The analysis emphasized this heterogeneity, supporting a move toward precision care in amyloidosis.
