JACC Executive Associate Editor Karthik Murugiah, MD, FACC, speaks with author Jasmine M. Marquard, MD, PhD, on her study published in JACC and presented at EuroPCR. The discussion focuses on 10-year outcomes, including repeated events, of fractional flow reserve (FFR)-guided complete revascularization versus treatment of the infarct-related artery only in ST-segment elevation myocardial infarction. As the original trial, the primary outcome was a composite of all-cause mortality, recurrent myocardial infarction, or any revascularization. Complete revascularization reduced the risk of the primary outcome by 24%. Complete re-vascularization showed an absolute reduction of 13 events (-1 to 28 events) per 100 persons after 10 years. FFR-guided complete revascularization reduced future and repeated events after 10 years, primarily by reducing revascularization rates, without reducing myocardial infarctions or death.

JACC: Associate Editor Michelle M. Kittleson, MD, PhD, FACC, and JACC: CardioOncology Deputy Editor Ronald Witteles, MD, FACC, discuss the current findings on the impact of vutrisiran in patients with transthyretin amyloidosis with cardiomyopathy (ATTR-CM). This study on HELIOS-B comprises details on cardiovascular (CV) events and provides updated mortality analyses from a later data cut than the primary analysis. Risk of ACM and CV events, including CV hospitalizations and heart failure events, was reduced with vutrisiran versus placebo in the overall population, with consistent trends regardless of baseline tafamidis use. These findings reinforce the balanced benefit on mortality and CV events demonstrated in the primary analysis of HELIOS-B.

Hosts Mitsuaki Sawano, MD, co-host Nobuhiro Ikemura, MD, welcome Kentaro Kamiya, PhD, from Kitasato University, to discuss the ACTIVE-ADHF trial, a landmark multicenter RCT on early cardiac rehabilitation in acute decompensated heart failure.
