Heart Disease

A new algorithm can effectively detect patients with a dangerous heart dysfunction using ECG data gathered by an Apple Watch. A large trial is now currently underway looking to test the clinical utility of the algorithm in one million people.

A robust new study led by researchers from Stanford University has found THC can trigger inflammation in blood vessel cells, and the researchers call for medical marijuana users to be aware of potential cardiovascular risks.

A panel of experts has updated its guidelines, recommending those over the age of 60 against taking aspirin to prevent heart attack or stroke. The advice is based on evidence indicating the harms of aspirin use outweigh any benefits in healthy adults.

In phase 1 trials, an RNA gene therapy has shown promise for reducing levels of a lipoprotein associated with a high risk of heart disease. The treatment could help fight a form of the disease that can’t currently be treated through lifestyle changes.

A new smartphone app called MyGeneRank has been developed by scientists at the Scripps Research Institute. The app calculates a person’s genetic risk for coronary artery disease and directs those found to be at high risk to appropriate medical advice.

Researchers have found sleeping in a moderately lit room can potentially harm a person’s cardiometabolic health. The study saw one night of sleep in a room with moderate light increased nighttime heart rates and spiked insulin resistance in the morning.

Coffee seems to have a range of health benefits, but exactly how it helps remains unknown. A new study has identified specific proteins that caffeine works on, which help the liver remove bad cholesterol and protect against cardiovascular disease.

A massive analysis of health records published in the journal Nature Medicine has found COVID-19 survivors were 55 percent more likely to experience a serious cardiovascular event in the year after recovering from acute disease.

Scientists have revealed a new mechanism through which an ingredient in common plastics drives up cholesterol and risk of cardiovascular disease in mice, potentially filling in some important blanks as to why similar effects have been observed in humans.

For people with coronary heart disease, regular monitoring of bloodstream cholesterol levels is essential – and it typically requires the drawing of blood samples. A new system, however, is claimed to provide the same data simply by imaging the skin of the hand.

Scientists have discovered a new type of cell in the heart. The cells, now named nexus glia, seem to help regulate heart rate and rhythm, and the team says they may unlock new understandings of some heart defects and diseases.

The results have been revealed from a study testing an algorithm designed to detect irregular heart rhythms using data from wearables. Enrolling nearly half a million subjects, the study detected undiagnosed atrial fibrillation in 98 percent of cases.
