MRI technique enables long-term tracking of transplanted stem cell-derived heart cells

Researchers at the Institute of Biomedical Engineering at the University of Toronto have demonstrated a new way to monitor transplanted stem-cell-derived heart cells using magnetic resonance imaging (MRI). The method allows ...

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 ...

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 ...

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 ...

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: ...

AI tool shows promise in diagnosing advanced heart failure

Applying artificial intelligence techniques to cardiac ultrasound data may make it easier to identify patients with advanced heart failure, a new study has found. The study—led by investigators at Weill Cornell Medicine, ...
