Heart Failure News and Research

RSS

Heart failure (HF) is a condition in which a problem with the structure or function of the heart impairs its ability to supply sufficient blood flow to meet the body's needs. It should not be confused with cardiac arrest or myocardial infarction.

Protein repair defects linked to hidden heart failure

Researchers in the del Monte Lab at the Medical University of South Carolina (MUSC) are the first to observe defects in the protein repair system associated with the peculiar, misfolded protein plaques previously observed in patients with idiopathic dilated cardiomyopathy (IDCM ).

Frailty flags poorer blood pressure control in older women

In 1,038 older adults with hypertension attending outpatient clinics in Vietnam, frailty was more common in women than men, while overall rates of suboptimal blood pressure were similar by sex. Frailty was associated with about twice the odds of suboptimal blood pressure in women, but not in men, highlighting the need to study sex-specific and frailty-informed hypertension care.

Extreme temperatures pose growing danger to heart health

Extreme heat and cold are growing cardiovascular risks that can trigger heart attacks, strokes, heart failure and sudden cardiac death, according to a recent scientific statement by experts at Weill Cornell Medicine and other leading institutions.

Major trials show finerenone preserves kidney function beyond diabetes

A series of major studies has shown that finerenone preserves kidney function, reduces cardiovascular risk, and improves survival across a much broader range of patients with chronic kidney disease (CKD) than it is currently recommended for.

Seven-second X-ray scan detects severe pulmonary valve regurgitation with high accuracy

Researchers at Kyushu University have developed a simple, rapid, and low-radiation X-ray technique that can evaluate the severity of a heart condition known as pulmonary valve regurgitation-a common and clinically significant complication after surgical repair of a congenital heart defect known as Tetralogy of Fallot.

Pulse-wave tracking at home catches spontaneous normal heart rhythms early

Smartphone-based heart rhythm monitoring from home can reduce same-day cancellations and help save significant healthcare resources ahead of planned electrical cardioversion in patients with atrial fibrillation. This is shown in a new study published in JAMA Cardiology by researchers at Karolinska Institutet and Danderyd Hospital.

What pregnancy reveals about a woman’s future heart health

Pregnancy acts as a natural cardiovascular stress test, revealing hidden heart disease and identifying women at higher long-term risk after complications such as preeclampsia, gestational diabetes, and preterm birth. The review highlights major evidence gaps in cardio-obstetric care and calls for stronger postpartum screening, dedicated women’s health clinics, and better inclusion of reproductive-age women in research.

New study reevaluates stroke risk for female patients with atrial fibrillation

A new Tulane University study challenges a long-standing assumption in heart care: that being female automatically increases stroke risk for patients with atrial fibrillation, a common condition that causes the heart to beat irregularly.

American Heart Association launches national heart transplant research network

Nearly 60 years after the first successful heart transplant, the American Heart Association, a relentless force changing the future of health for everyone everywhere, is launching a bold new initiative to fundamentally transform how heart transplant care is delivered across the United States - addressing long-standing gaps in innovation, equity and patient outcomes.

Heart failure therapy referrals vary widely across the United Kingdom

Substantial variations in referrals for advanced heart failure therapies are apparent across the UK and Ireland, with no obvious link to geographical location or social deprivation to explain the findings, reveals the first national audit of its kind, published online in the open access journal Open Heart.

Experts urge specialized heart centers for women across European healthcare

Women are more likely to face delays in diagnosis of cardiovascular disease and, as a result, they are more likely to die or develop more serious illness. To address this in inequality, Europe needs dedicated women's heart centers, according to a report published in the European Heart Journal today (Tuesday).
