Heart Disease

What Causes High Blood Pressure?

Blood pressure is the term used to describe the pressure exerted on the arterial walls as blood flows through them. This pressure is at its highest when the heart contracts and pumps blood through the arteries and is called the systolic pressure.

AI eye scans reveal who may be at higher risk of osteoporosis

RetiAGE, an AI-derived retinal biological age score, was associated with lower bone mineral density and higher fracture risk scores in older Singaporean adults. In the UK Biobank, older retinal biological age also predicted future osteoporosis, suggesting routine retinal imaging could eventually support opportunistic osteoporosis risk screening.

New obesity medications offer a potent tool for combating hypertension

A meta-analysis of 32 studies and 43,618 adults presented at this year's European Congress on Obesity in Istanbul, Turkey (12-15 May) shows that use of new classes of obesity drugs for weight loss is associated with a clinically relevant drop in blood pressure (BP): a 0.34 mmHg reduction in systolic BP per 1\% weight loss.

Healthy plant-based foods may improve pregnancy cardiometabolic markers

Higher-quality plant-based diets were associated with more favorable cardiometabolic biomarkers in pregnant U.S. women, especially higher HDL-C and lower TG/HDL-C ratio. Indices that emphasized healthy plant foods, rather than simply penalizing animal foods, showed the strongest links with insulin resistance and lipid markers.

Stent-assisted coiling and flow diverters effectively treat rare basilar artery cases

Basilar trunk artery aneurysms (BTAs) are among the rarest and most complex types of brain aneurysms, occurring in a critical vessel that supplies blood to the brainstem. Because of their location and low incidence, there has been limited research guiding how best to treat them, leaving neurosurgeons with few large datasets to inform clinical decisions.

The Goldilocks sleep zone: study links too little and too much sleep to biological aging

The Nature study introduces “Sleep Chart,” a framework linking self-reported sleep duration with 23 biological aging clocks derived from MRI, plasma proteomics, and metabolomics. Across UK Biobank participants, the lowest biological age gaps generally appeared between 6.4 and 7.8 hours of sleep, while shorter and longer sleep were associated with higher disease and mortality risk.
