Forty percent of deaths attributed to cardiac arrest are not sudden or unexpected, and nearly half of the remainder are not arrhythmic -- the only situation in which CPR and defibrillators are effective -- according to an analysis by researchers at UC San Francisco and the City and County of San Francisco Office of the Chief Medical Examiner.
UC San Francisco scientists have improved mobility in rats that had experienced debilitating strokes by using electrical stimulation to restore a distinctive pattern of brain cell activity associated with efficient movement. The researchers say they plan to use the new findings to help develop brain implants that might one day restore motor function in human stroke patients.
Researchers have linked sensitivity to an allergen in red meat -- a sensitivity spread by tick bites -- with a buildup of fatty plaque in the arteries of the heart. This buildup may increase the risk of heart attacks and stroke.
Screening for abdominal aortic aneurysm -- swelling of the major artery in the abdomen, which can cause sudden death if it ruptures -- may not substantially reduce deaths from the condition, according to a Swedish cohort study of more than 130,000 men published in The Lancet. The findings question the need for the screening, which is also conducted in the UK and US.
Flavoring chemicals widely used in e-cigarettes and other tobacco products may be toxic to the cells that line and regulate blood vessel function. The adverse effects observed with chemical flavor additives on endothelial cells could be early warning signs of future heart disease, researchers say.
The new journal Cardiovascular Innovations and Applications (CVIA) has just published the first issue of Volume 3. This is a special issue on adult congenital heart disease with guest Editor Diego Moguillansky of the University of Florida Medical School.
Adopting a Mediterranean-style eating pattern improves heart health, with or without reducing red meat intake, if the red meat consumed is lean and unprocessed, according to a Purdue University nutrition study.
Immune cells promoting inflammation play a crucial role in the development of atherosclerosis. Scientists at CeMM and the Medical University of Vienna in collaboration with the University of Cambridge showed that a survival factor for those cells has also anti-inflammatory functions and a protective role in atherosclerosis. The study, published in Circulation, provides valuable new insight for atherosclerosis research and suggests a hitherto unknown, inherited risk factor for atherosclerosis.
New findings from the long-running Whitehall II study of over 10,000 civil servants has found 50-year-olds who had blood pressure that was higher than normal but still below the threshold commonly used when deciding to treat the condition, were at increased risk of developing dementia in later life. This increased risk was seen even when the study participants did not have other heart or blood vessel-related problems, according to the research, which is published in the European Heart Journal.
People who are prescribed a combination pill to manage their high blood pressure are more likely to take their medicine as instructed and have better health outcomes than those who take the same medications prescribed as separate pills, according to a new study published today.
