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.

Rivaroxaban shown to be a viable alternative to warfarin for left ventricular thrombus

At three months of follow-up, patients hospitalized for a serious heart attack who were treated with the oral blood thinner rivaroxaban for a blood clot in the left ventricle did as well as similar patients who received standard treatment with warfarin, an older blood-thinning drug.

Zero coronary artery calcium score predicts low heart risk at any age

Having a coronary artery calcium (CAC) score of zero has generally been accepted as a marker of a very low risk of having a cardiac event within the next five years. However, age is a strong contributor to coronary risk, with risk increasing markedly as people age.
