How have power to you tell if you or someone you be aware of is having a heart attack? Sometimes the symptoms have power to be surprisingly subtle. "They can subsist very different from person to part, between women and men and just within an individual who has to a greater degree than one heart attack," says Dr. David Rizik, superintendent of Interventional Cardiology for Scottsdale Healthcare Hospitals, in Scottsdale, Ariz. Men and women may actual presentation atypical heart attack symptoms. In ing to the "classic" chest-splitting, gasping-despite-breath symptoms, many heart attacks start with symptoms that are so kind they are often mistaken for indigestion or muscle ache.
Asthma sufferers have long relied on inhalers for support from wheezing or coughing attacks. But because of Dec. 31, Primatene Mist -- the barely available over-the-counter asthma inhaler -- was taken over shelves because of its adverse general intent on the environment. Other inhalers are suitable, but these require a doctor's custom. Some people with asthma aren't befitting about the change, but lung doctors and asthma specialists agree that Primatene Mist wasn't the most of all option for patients anyway.
Plantar fasciitis. If you asylum't had to deal with it personally, straightforward ask around. Chances are you be sure lots of people who can portray it in great detail: stabbing back of the foot pain and agonizing steps followed the agency of a frustratingly slow recovery. Plantar fasciitis - every inflammation of the plantar facsia, a friendly band of tissue that runs longitudinally the arch from the heel to the toes - has get so ubiquitous that podiatrists can practically be active the diagnosis before a patient verily sets foot in their office.
Researchers in the US acquire identified a protein that rejuvenates antique hearts in mice. The mouse hearts had thickened walls, a sign of aging homogeneous to that seen in humans, end after treatment their hearts reduced in largeness and thickness, and became more like the hearts of junior mice.
The researchers suggest the protein, known considered in the state of growth differentiation factor 11 (GDF-11), may evidence to be the first effective method of treating for a form of age-of the same nature heart failure, called diastolic heart failure, that affects millions of Americans and times involves thickening of the heart muscle (cardiac hypertrophy) in the elderly.
Led dint of two Harvard professors, stem cell biologist Amy Wagers, and practising cardiologist Richard T. Lee, the team writes around its findings in a paper published online in the diary Cell on 9 May.
Lee, who is a Harvard Medical School professor at Brigham and Women's Hospital in Boston and a most considerable faculty member at Harvard Stem Cell Institute (HSCI), says in a announcement: "The most common form of emotion failure [in the elderly] is in fact a form that's not caused the agency of heart attacks but is very plenteous related to the heart aging." Referring to the study taken in the character of "the coolest thing I've till doomsday been a part of", Lee says that giving GDF-11 to older mice appeared to make void heart aging in a very inadequate period of time.
"We are excessively excited about it because it opens a fresh window on the most common conation of heart failure," he adds. Lee says in an opposite direction 20 of his 300 patients regard diastolic heart failure. Currently their treatment consists of coming to the hospital and having a part of fluid taken off, then going home. Then they get to back again and do the well thing again. He says the defectiveness of drugs to treat this condition is "very frustrating".
"We need to toil as hard as we can to outline out if this discovery can have existence turned into a treatment for seat of life failure in our aging patients," he urges.
