Heart attack survivors may be less likely to develop Parkinsons disease - حمله قلبی و پارکینسون

Research Highlights:

  • People who have had a heart attack are at increased risk of stroke and vascular dementia; however, a new study found they may be less likely to develop Parkinson’s disease.
  • A large, nationwide study in Denmark found that the risk of Parkinson’s disease was moderately lower among people who have had a heart attack than among the general population.

People who have had a heart attack may be slightly less likely than people in the general population to develop Parkinson’s disease later in life, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed Journal of the American Heart Association.

Parkinson’s disease is a brain disorder characterized by progressive loss of physical movement, including tremors, slow or slurred speech, and/or stiffness or limited range of motion for walking and other physical activities. There is no cure for Parkinson’s disease, and it is also associated with behavioral changes, depression, memory loss and fatigue. Secondary parkinsonism, which has symptoms similar to Parkinson’s disease, may be caused by stroke, psychiatric or cardiovascular medications, or other illness.

The researchers examined health registries from the Danish National Health Service. They compared the risk of Parkinson’s disease and secondary parkinsonism among about 182,000 patients who had a first-time heart attack between 1995 and 2016 (average age 71 years old; 62% male) and more than 909,000 controls matched for age, sex and year of heart attack diagnosis. The results were adjusted for a variety of factors known to influence the risk of either heart attack or Parkinson’s disease.

COVID19 infections increase risk of heart conditions up to a year later - کرونا و قلب

An in-depth analysis of federal health data indicates that people who have had COVID-19 are at increased risk of developing cardiovascular complications within the first month to a year after infection. Such complications include disruptive heart rhythms, inflammation of the heart, blood clots, stroke, coronary artery disease, heart attack, heart failure or even death.

Such problems occur even among previously healthy individuals and those who have had mild COVID-19 infections, according to the study, from researchers at Washington University School of Medicine in St. Louis and the Veterans Affairs St. Louis Health Care System.

The research is published Feb. 7 in Nature Medicine.

“We wanted to build upon our past research on COVID’s long-term effects by taking a closer look at what’s happening in people’s hearts,” said senior author Ziyad Al-Aly, MD, an assistant professor of medicine at Washington University. “What we’re seeing isn’t good. COVID-19 can lead to serious cardiovascular complications and death. The heart does not regenerate or easily mend after heart damage. These are diseases that will affect people for a lifetime.”

Repairing hearts with deadly spider venom - درمان سکته قلبی با سمی کشنده!

A potentially life-saving treatment for heart attack victims has been discovered from a very unlikely source – the venom of one of the world’s deadliest spiders.

A drug candidate developed from a molecule found in the venom of the Fraser Island (K’gari) funnel web spider can prevent damage caused by a heart attack and extend the life of donor hearts used for organ transplants.

The discovery was made by a team led by Dr Nathan Palpant and Professor Glenn King from The University of Queensland (UQ) and Professor Peter Macdonald from the Victor Chang Cardiac Research Institute.

Dr Palpant, from UQ’s Institute for Molecular Bioscience (IMB), said the drug candidate worked by stopping a ‘death signal’ sent from the heart in the wake of an attack.

This research was published in Circulation and funded by The University of Queensland, the Australian National Health and Medical Research Council and the National Heart Foundation of Australia. The lead authors are Dr Meredith Redd (Institute for Molecular Bioscience, UQ) and Dr Sarah Scheuer (Victor Chang Cardiac Research Institute).

Too Much Too Little Sleep Linked to Elevated Heart Risks in People Free from Disease - خواب کافی نه افراط نه تفریط

People who clock six to seven hours of sleep a night had the lowest chance of dying from a heart attack or stroke when compared with those who got less or more sleep, according to a study being presented at the American College of Cardiology’s 70th Annual Scientific Session. This trend remained true even after the research team accounted for other known conditions or risk factors for heart disease or stroke.
The study, according to researchers, is the first to explore the association between baseline cardiovascular risk and duration of sleep and adds to mounting evidence that sleep—similar to diet, smoking and exercise—may play a defining role in someone’s cardiovascular risk.

Plant-based diets shown to lower blood pressure even with limited meat and dairy - رژیم غذایی گیاهی می تواند به کاهش فشارخون کمک کند
  • A diet rich in plant-based foods can include a limited amount of animal products and still improve blood pressure, new research from University of Warwick demonstrates
  • Researchers compared the impact of seven plant-based diets on blood pressure in a systematic review of previous studies
  • High blood pressure is the leading risk factor globally for heart attacks, strokes and other cardiovascular diseases
  • Lead author Joshua Gibbs of University of Warwick: “Essentially, any shift towards a plant-based diet is a good one.”

Consuming a plant-based diet can lower blood pressure even if small amounts of meat and dairy are consumed too, according to new research from the University of Warwick.

Published online by a team from Warwick Medical School in the Journal of Hypertension today (25 July), they argue that any effort to increase plant-based foods in your diet and limit animal products is likely to benefit your blood pressure and reduce your risk of heart attacks, strokes and cardiovascular disease. They conducted a systematic review of previous research from controlled clinical trials to compare seven plant-based diets, several of which included animal products in small amounts, to a standardised control diet and the impact that these had on individuals’ blood pressure.

Exploring how a scorpion toxin might help treat heart attacks - سم عقرب ممکن است در پیشگیری از سکته های قلبی موثر باشد

“Moving Pieces in a Cellular Puzzle: A Cryptic Peptide from the Scorpion Toxin Ts14 Activates AKT and ERK Signaling and Decreases Cardiac Myocyte Contractility via Dephosphorylation of Phospholamban”
Journal of Proteome Research

Scientists are discovering potential life-saving medicines from an unlikely source: the venom of creatures like snakes, spiders and scorpions. Scorpion venom, in particular, contains a peptide that has beneficial effects on the cardiovascular system of rats with high blood pressure. Now, researchers reporting in ACS’ Journal of Proteome Research say they know a little more about how that happens.

کووید19 و سکته - COVID19 and strok

COVID-19 can cause serious cardiovascular complications including heart failure, heart attacks and blood clots that can lead to strokes, emergency medicine doctors report in a new scientific paper. They also caution that COVID-19 treatments can interact with medicines used to manage patients’ existing cardiovascular conditions.
