People with both cavities and gum disease had an 86% higher risk of ischemic stroke than those with healthy mouths, according to research published October 22, 2025, in Neurology Open Access. The two-decade study of 5,986 adults linked poor oral health to higher rates of major cardiovascular events, while emphasizing the findings show association, not causation.
Immune protein promotes arrhythmias after heart attacks
Researchers at Massachusetts General Hospital have identified an immune protein that damages heart cells after a myocardial infarction, leading to dangerous arrhythmias. By targeting this protein in mice, the team reduced arrhythmia incidents twelvefold. The findings suggest new ways to prevent sudden cardiac death.
Hidden fat damages arteries even in seemingly healthy people
Researchers at McMaster University have discovered that visceral fat around organs and fat in the liver can silently harm arteries, increasing stroke and heart attack risks, regardless of outward appearance. The study, involving MRI scans of over 33,000 adults, challenges the reliability of BMI for assessing cardiovascular health. Published on October 17, 2025, the findings urge a shift toward imaging-based evaluations.
Different depression types tied to distinct physical health risks
Bananas may reduce flavanol absorption in smoothies, UC Davis-linked study finds

A small UC Davis–affiliated trial reports that a banana-based smoothie markedly lowered the body’s uptake of flavan-3-ols—about 84% less at peak plasma levels than after a control capsule—an effect the researchers link to the fruit’s polyphenol oxidase enzyme.
Stem cell therapy lowers heart failure risk after heart attack
A large clinical trial has shown that infusing mesenchymal stem cells from umbilical cord blood shortly after a first heart attack reduces the risk of developing heart failure by nearly 60 percent over three years. The treatment, administered within three to seven days, also improved heart pumping function compared to standard care. Researchers from Shiraz University in Iran led the study, providing strong evidence for stem cells' regenerative potential.
Randomized trial finds certain processed hard fats did not worsen short-term heart risk markers

A small randomized crossover study found no meaningful differences in cholesterol or other short‑term cardiometabolic markers when healthy adults consumed either palmitic‑rich or stearic‑rich interesterified fats for six weeks apiece.
Men over 50 need more exercise than women for heart benefits
A new study reveals that men over 50 must exercise nearly twice as much as women to achieve similar reductions in coronary heart disease risk. Using data from activity trackers, researchers found significant sex differences in exercise benefits for heart health. The findings suggest a need for updated, gender-specific health guidelines.
