Early heart disease risk factors identified in South Asian adults in the U.S.

South Asian adults in the U. S. were more likely to have risk factors for atherosclerotic cardiovascular disease (ASCVD) by age 45 when compared to white, Black, Chinese or Hispanic adults in the same age group, according to a study published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Healthy low-carbohydrate and low-fat diets may improve cardiovascular health

The quality of a low-carbohydrate or low-fat diet may matter more than the amount of carbohydrates or fat consumed when it comes to reducing heart disease risk, according to a new study published in JACC, the flagship journal of the American College of Cardiology.

Night-time traffic noise may affect metabolic health

A new study has found that nighttime noise exposure is associated with changes in blood cholesterol and lipid-related metabolites in adults, which are known risk factors for cardiometabolic diseases.

South Asian adults in the U.S. have higher prevalence of risk factors for heart disease

South Asian adults in the U.S. report doing many of the right things for heart health, yet they show significantly higher rates of prediabetes, diabetes and hypertension than white and Chinese adults, and higher than or roughly similar rates to Black and Hispanic patients, according to a new study led by Northwestern Medicine.

Eating fewer foods of concern may protect the heart beyond pills

A prospective cohort study in adults with hypertension and or hypercholesterolemia found that lower intake of ultra processed foods or foods flagged by front of pack nutrition warnings was associated with reduced cardiovascular disease risk. These associations persisted regardless of cardioprotective medication use, suggesting dietary quality contributes independently to cardiovascular prevention.

New analysis asks if alcohol guidance needs stronger trials to settle the health debate

The viewpoint reviews conflicting evidence on alcohol consumption, highlighting discrepancies between observational studies, genetic analyses, and public health guidance. It concludes that large randomized trials comparing alcohol moderation versus cessation are needed to clarify long-term health effects.

Tirzepatide shows dual benefits in sleep apnea trial improving metabolism and reducing inflammation

Tirzepatide significantly improved cardiometabolic risk markers in adults with obesity and moderate to severe obstructive sleep apnea in the SURMOUNT-OSA phase 3 trials. Mediation analyses suggest both weight loss and reduced sleep-disordered breathing contributed to improvements in inflammation, insulin resistance, lipids, and blood pressure.

Cognitive speed training shows potential to delay dementia for two decades

Adults age 65 and older who completed five to six weeks of cognitive speed training - in this case, speed of processing training, which helps people quickly find visual information on a computer screen and handle increasingly complex tasks in a shorter time period - and who had follow-up sessions about one to three years later were less likely to be diagnosed with dementia, including Alzheimer's disease, up to two decades later, according to new findings published today in Alzheimer's & Dementia: Translational Research and Clinical Interventions.
