Individuals with worse cardiac structure at higher risk of developing adverse health outcomes and mortality long-term

Higher left atrial end-systolic dimension (LASD), an increased measurement of the left upper chamber of the heart, and left ventricular mass (LVM), a clinical measurement of the weight of the heart's left ventricular myocardium, ...

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 ...

Study links cold weather with excess cardiovascular deaths

On the heels of one of the coldest winters in memory for large swaths of the United States, new research highlights an often overlooked cost of cold weather: months with lower temperatures see significantly greater rates ...

New 4D model advances precision treatment for heart failure

A made-in-Calgary 4D heart model is transforming treatment for heart failure patients having a specialized pacemaker inserted, called cardiac resynchronization therapy (CRT). In a clinical trial, published in Circulation: ...

Excessive screen time signals health risk for young adults

People who reported spending six or more hours on screens outside of school or work had worse blood pressure, cholesterol, and body mass index (BMI) compared with those with more limited screen time, according to a study ...

Transportation noise: An overlooked risk to heart health

Living in areas with consistently higher levels of noise from transportation is associated with a significantly higher risk of major adverse cardiac events compared with living in quieter areas, according to a study presented ...

AI can predict risk of serious heart disease from mammograms

The risk of serious or fatal heart disease can be predicted with artificial intelligence (AI) analysis of mammograms, according to research published in the European Heart Journal. The study shows that AI can be used to assess ...

Single saRNA shot helps with healing after a heart attack

For people who have survived a heart attack, the notion of one shot in the arm to help the heart heal, for weeks after, may seem far-fetched. But thanks to a team of researchers, including a Texas A&M University professor, ...

Gut microbiome connected with heart disease precursor

Before the onset of cardiovascular disease symptoms, people often develop dyslipidemia, or abnormal levels of lipids in the blood. Recent studies suggest that microbes in the gut play an important role in how the body produces, ...

How estrogen helps protect women from high blood pressure

High blood pressure, or hypertension, affects more than one billion people worldwide and is a leading cause of heart disease and stroke. For decades, researchers have observed that premenopausal women are less likely to develop ...
