Mitochondria manufacture energy in every cell of the body, including heart muscle cells. A new study from Washington University School of Medicine in St. Louis shows that cardiac mitochondria are abnormal in the offspring of mouse mothers that become obese due to a high-fat, high sugar diet. Those offspring then pass on the mitochondrial defects at least two more generations.
Patients in a new Northwestern Medicine study were able to comprehend words that were written but not said aloud. They could write the names of things they saw but not verbalize them. For instance, if a patient in the study saw the word 'hippopotamus' written on a piece of paper, they could identify a hippopotamus in flashcards. But when that patient heard someone say 'hippopotamus,' they could not point to the picture of the animal.
New research published in the March 18 edition of Lipids showed that people who have peripheral artery disease (PAD) have a lower Omega-3 Index compared to those who don't have the disease. Because PAD is essentially atherosclerosis of the leg arteries, researchers in this study believe that patients with PAD may have an omega-3 fatty acid deficiency.
Researchers from the George Washington University and the Moscow Institute of Physics and Technology have developed a solution for multiparametric optical mapping of the heart's electrical activity. This technique is a useful tool for enhancing our understanding of the mechanisms behind cardiac arrhythmias. Arrhythmia causes your heart to beat too quickly, too slowly or erratically. Hijacking the heart's vital rhythm and pumping function can have serious consequences like a stroke or cardiac arrest.
A UCLA-led study confirms what women approaching menopause have long suspected: menopause does make fat go up. The study finds that women undergoing perimenopause lost lean body mass and more than doubled their fat mass. The research demonstrates that body mass index (BMI) is a very important clinical tool for predicting health events, such as getting diabetes or having cardiovascular disease -- but is a less useful gauge of cardio-metabolic risk in older women.
Researchers at Karolinska Institutet in Sweden have found that type IgG antibodies play an unexpected role in atherosclerosis. A study on mice shows that the antibodies stabilize the plaque that accumulates on the artery walls, which reduces the risk of it rupturing and causing a blood clot. It is hoped that the results, which are published in the journal Circulation, will eventually lead to improved therapies.
A toilet-seat based cardiovascular monitoring system created by a team of Rochester Institute of Technology researchers aims to lower the hospital readmission rates of patients with congestive heart failure.
Risks of death from heart disease and stroke vary among American-Asian subgroups, with Asian Indian, Filipino and Vietnamese populations at greatest risk for losing years of life to heart disease or stroke. All Asians had higher years of life lost to stroke than non-Hispanic whites.
As our collection of resident gut bacteria changes with age, it increasingly produces harmful metabolites that damage veins and blood vessels, driving disease, a new study suggests
Severely impaired stroke survivors are regaining function in their arms after sometimes decades of immobility, thanks to a new video game-led training device invented by Northwestern Medicine scientists.
