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 ...

AI model identifies patients at risk of underdiagnosed cause of high blood pressure

A study of a new AI model examining 30 years of routine electronic health records (EHR) data could improve screening for primary aldosteronism, a leading cause of high blood pressure that is often unrecognized but increases ...

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 ...

More aggressive cholesterol-lowering improves heart outcomes

Using cholesterol-lowering medications more intensively to achieve a more aggressive target for low-density lipoprotein cholesterol (LDL-C) reduced the rate of major cardiovascular events by one-third among patients with ...

The new cholesterol guideline: What to know

For the first time since 2018, a clinical guideline from the American College of Cardiology and the American Heart Association for screening and managing blood cholesterol levels has been updated and jointly published in ...

Zone 2, 3, 4? What do heart rate zones mean for your health?

Runners, cyclists and gym-goers with wearable fitness trackers are no doubt familiar with the five "heart rate" zones. Ranging from low to very high intensity, these zones are calculated as percentages of a person's maximum ...

New MRI system could aid early detection of heart failure

The heart's ability to use oxygen efficiently is a critical indicator of its health, but tests to measure this function have drawbacks that can limit their use. A new Cedars-Sinai Health Sciences University study found that ...

AI model reads cardiac MRI scans with near expert accuracy

A Penn Medicine–led team has developed a first-of-its-kind artificial intelligence system that interprets cardiac MRI scans with performance approaching expert clinicians. Trained on more than 300,000 MRI video clips from ...

Lower hemoglobin levels may offer several health benefits

Hemoglobin is a vital protein found in red blood cells and its primary function is to transport oxygen from the lungs to various tissues throughout the body. According to Finnish reference values, normal hemoglobin levels ...
