Layne Helmering and her family lost their son Nicholas last year to hypertrophic cardiomyopathy. A high school senior and captain of his debate team, Nicholas passed away suddenly in his sleep. In the wake of this tragic loss, Nicholas’s debate team held a fundraiser, coming together to raise awareness of HCM, a disease of the heart muscle that makes it harder for the heart to pump blood to the rest of the body.
Mass General Brigham researchers and collaborators from Washington University School of Medicine in St. Louis and Emory University’s Rollins School of Public Health pooled data from 99 countries and 810,635 adults to determine how many people worldwide may benefit from GLP-1 use. They found more than one in four adults would be eligible for GLP-1s for weight management, with women, older individuals, and low- and middle-income countries among the most eligible. These critical metrics could be formative in policy development to deploy GLP-1s around the world to tackle obesity and its comorbidities. Their results are published in a research letter in The Lancet Diabetes & Endocrinology.

knew something wasn’t right. Marcy has Marfan syndrome, a genetic condition that weakens the body’s connective tissue. Because she has been under the care of Alan Braverman, MD, a WashU Medicine cardiologist at Barnes-Jewish Hospital and world-leading expert in Marfan syndrome, she knew that the condition put her at an increased risk for cardiovascular issues—but she never expected to face one so suddenly.
As we begin the new year, I am filled with gratitude for the enormous contributions our faculty, staff and trainees have made, providing outstanding care for patients, performing groundbreaking research and delivering exceptional educational programs.

At 82 years old, Lois Miles was one of the first patients at Barnes-Jewish Hospital to receive a transcatheter tricuspid valve implant, a groundbreaking procedure performed in 2024. It’s one more way the hospital and its academic physician partner, WashU Medicine, are helping patients with valve disease.
For years, Lois’ leaky tricuspid valve caused blood to flow backward in her heart. She also had atrial fibrillation, a condition that caused her heart to beat too fast, adding even more complexity to her case. She often felt short of breath, became full quickly when eating, and just didn’t feel right.

When Ashley Brooks, RN, BSN, was born, the first hint her parents received that something was out of the ordinary was that nurses didn’t bring their infant daughter from the nursery to their room when it was time to eat. She had been taken to the hospital’s neonatal intensive care unit.
Something was different about Ashley’s heart, but physicians didn’t quite know what. Answers finally came when Ashley was 4 and doctors diagnosed her with restrictive cardiomyopathy, a heart condition in which the heart muscle is too stiff to pump blood properly. Ashley’s childhood, however, was pretty normal—until she turned 18. That year, while she was a senior in high school, she had a stroke, and her doctors decided it was time for her to get on the wait list for a heart transplant. Over the course of two years, her condition worsened, and in 2005, when she was 20, Ashley got the call. There was a heart ready for her.

A new paper in JACC: Advances delves into the factors that may affect implementation of a polypill for heart failure with reduced ejection fraction (HFrEF)—assuming one proves safe and effective—and outlines strategies for an eventual rollout.
This exercise “just reinforces the idea, in addition to previous data showing therapeutic inertia and reluctance to use other single-pill combination therapies for cardiovascular diseases, that we need to plan in advance. We need to be strategic in how we design the heart failure polypill and how we implement it, and what strategies and what messages we provide with that,” said Justin Chen, MD (WashU Medicine, St. Louis, MO), one of the lead authors.

Doxorubicin has been a mainstay in cancer treatment for more than 50 years. Sometimes called “red devil chemo,” it is potent and effective against many cancer types. But it comes with a major downside — increased risk of severe heart failure, even decades after successful cancer treatment.Now researchers led by WashU Medicine cardiologist Ali Javaheri, MD, PhD, have identified a type of immunotherapy that prevents and treats the heart muscle damage caused by doxorubicin, based on their findings in human heart tissue, cell lines and mouse models of heart failure. The study appears in the journal Circulation.
