FAME-3 study reveals similar outcomes for CABG and PCI in severe triple-vessel heart disease

In sharp contrast to earlier studies, patients with severe triple-vessel heart disease fared equally well whether they underwent open-heart bypass surgery (CABG) or a less invasive procedure called PCI (percutaneous coronary intervention) at five years of follow-up, according to research presented at the American College of Cardiology's Annual Scientific Session.

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.

Atrial fibrillation elevates early-onset dementia risk in younger adults

New research presented at the EHRA 2025, a scientific congress of the European Society of Cardiology, shows that the presence of atrial fibrillation (AF) increases the risk of future dementia by 21% in patients diagnosed with AF under 70 and the risk of early-onset dementia (diagnosed before age 65 years) by 36%.

Heart failure patients benefit from dapagliflozin after TAVR procedure

Patients with heart failure who took dapagliflozin, a sodium-glucose co-transporter-2 (SGLT-2) inhibitor, after undergoing transcatheter aortic valve replacement (TAVR) were significantly less likely to die or experience worsening heart failure at one year compared with patients who did not take the drug, according to a study presented at the American College of Cardiology's Annual Scientific Session.

Hedonic eating fades with obesity—but neurotensin helps bring it back

Chronic high-fat diets blunt the brain’s pleasure response to rich foods by impairing NAcLat→VTA signaling in mice. Neurotensin dysfunction underlies this effect, but restoring its signaling revives hedonic feeding and reduces obesity symptoms.
