Smartwatches could predict risk of hospitalization due to heart failure

Paula Vanderpluym's smartwatch may look like a small part of her wardrobe, but to a team of researchers in Toronto, it represents something bigger: the potential to proactively care for people living with heart failure. A ...

AI model suggests CPAP can massively swing heart risk in sleep apnea

Mount Sinai researchers have created an analytic tool using machine learning that can predict cardiovascular disease risk in millions of patients with obstructive sleep apnea, a serious sleep disorder, according to findings ...

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 ...

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 ...

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 ...

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: ...

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 ...
