How a simple blood test could help detect heart damage during breast cancer treatment

Modern breast cancer screening and treatment have transformed survival. Many women now live long and healthy lives after diagnosis, thanks to increasingly effective chemotherapy and targeted therapies: medicines designed ...

Simple blood test unveils hidden risks of unstable coronary plaques

A straightforward blood-based assessment developed at the Institute of Science Tokyo, Japan, can help assess how effectively high-density lipoprotein (HDL) removes cholesterol from blood vessel walls, a function known as ...

GLP-1s tied to elevated risk of fainting, dizziness

Northwestern Medicine scientists have identified a safety concern associated with GLP-1 drugs. Using health record data, the research team tracked more than 42,000 adults already taking at least two types of blood pressure ...

Brain aneurysm map reveals cell types tied to rupture risk

A new study from UC San Francisco shows how certain cells in the brain may cause aneurysms to weaken and rupture. It helps explain why some aneurysms burst while others do not and could lead to new ways of predicting and ...

Molecular mechanics behind heart cell restructuring revealed

Microtubules, part of heart muscle cells' internal "skeleton," help determine how the heart changes shape under stress, and a common signaling pathway called the ERK pathway acts as a key controller of where the building ...

Statin use linked to lower risk of frailty in older veterans

Researchers at Mass General Brigham have demonstrated that older U.S. veterans who initiated statin therapy were significantly less likely to develop frailty over time, suggesting that the cholesterol-lowering medications ...

Unraveling the mystery of misfolded proteins in the heart

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 ...

Researchers use earbuds to monitor heart health

Carnegie Mellon researchers have proven that widely available earbuds can double as heart-monitoring devices, capturing subtle cardiac activity with near-clinical accuracy and potentially expanding access to long-term, at-home ...

Sleep patterns may reveal hidden heart risks

People whose sleep apnea changes dramatically from night to night are 30% more likely to have a heart attack, stroke, or heart failure, reveals a new study from Flinders University. The research, published in the journal ...

Study identifies genetic drivers of resistant hypertension

Cedars-Sinai investigators have identified distinct genetic variants associated with resistant hypertension, a type of high blood pressure that remains uncontrolled despite medication. Their findings, published in the journal ...

AED algorithm could improve location of lifesaving devices

Cedars-Sinai Health Sciences University investigators and colleagues created an algorithm designed to use data on sudden cardiac arrests to determine the best public locations for lifesaving devices called automated external ...

Rare MGRN1 gene variant tied to fetal heart malformations

The Human Genetics Research Group of the University of Tartu Faculty of Medicine has identified a gene whose defect may cause congenital heart malformations in the fetus. The MGRN1 gene has not previously been associated ...

Irregular bedtime linked to higher risk of cardiac events

An irregular bedtime in midlife may signal an increased risk of cardiovascular disease. A new study from the University of Oulu suggests that large swings in when people go to bed could double the risk of serious cardiac ...

Digital twin hearts deliver 100% success in arrhythmia trial

Working with "digital twins" of patients' hearts, doctors have improved cardiac ablation outcomes for patients with life-threatening arrhythmias. In the first clinical trials for cardiac digital twins technology, researchers ...
