Antidepressant use associated with higher risk of sudden cardiac death in all age groups

Sudden cardiac death (SCD) refers to an unexpected death of a person, believed to be caused by a heart-related issue. It occurs within one hour of the onset of symptoms in witnessed cases or within 24 hours of the person being last seen alive in unwitnessed cases.

AI model matches high-sensitivity troponin testing in diagnosing heart attacks

An artificial intelligence (AI) model trained to detect blocked coronary arteries based on electrocardiogram (ECG) readings performed better than expert clinicians and was on par with troponin T testing, according to research presented at the American College of Cardiology's Annual Scientific Session (ACC.25).

WARRIOR trial finds no impact of intensive therapy on heart events in women

An intensive three-drug regimen of heart medications did not significantly impact the rate of serious cardiovascular events at five years in women who experienced signs and symptoms of ischemia, or insufficient blood flow to the heart muscle, but had no blockages in their heart's arteries, according to research presented at the American College of Cardiology's Annual Scientific Session.

Study aims to determine best method for statin prescription in coronary heart disease

A new study by researchers at Intermountain Health in Salt Lake City aims to determine the best method to screen and evaluate patients who are at risk of developing coronary heart disease and which patients would benefit from taking a statin medication to lower cholesterol.

Negative stiffness in calf muscles enhances high-speed hopping

Researchers at the University of Tokyo reveal the way our legs adapt to fast movements. When people hop at high speeds, key muscle fibers in the calf shorten rather than lengthen as forces increase, which they call "negative stiffness." This counterintuitive process helps the leg become stiffer, allowing for faster motion. The findings could improve training, rehabilitation, and even the design of prosthetic limbs or robotic exoskeletons.

Flavonoids help regulate gut hormones and show promise in managing type 2 diabetes

Flavonoids show promise in treating type 2 diabetes mellitus by targeting the enteroendocrine system and regulating key gut hormones. They enhance insulin sensitivity, reduce oxidative stress, and influence appetite, glucose uptake, and hormone secretion.

Cedars-Sinai study shows rapid healing of heart damage with cell therapy

A scientific technique that rapidly increases the body's production of anti-inflammatory cells promoted healing from heart attacks in mice, according to a new study by investigators from the Smidt Heart Institute at Cedars-Sinai. Once adapted to treat humans, the technique could potentially be used to repair heart muscle damage after a heart attack and be applied to a variety of inflammatory disorders.
