Could aspirin therapy become a standard post-operative treatment following bypass surgery? A new study shows patients who were given aspirin in the first 48-hours following bypass surgery had fewer complications and a lower risk of death during that critical post-operative period. And the aspirin patients also showed no increase in bleeding related to the therapy. The study involved 5-thousand bypass patients and is published in the New England Journal of Medicine. Those who were given aspirin had about one-third the risk of death during hospitalization compared to patients who did not receive aspirin. The aspirin patients also had a more than one-third reduction in the risk of complications involving the heart, brain, kidneys or gastrointestinal tract.
Have you ever donated blood, or maybe stood in line for a really long time and felt like you were going to faint? In a new study presented at the American Heart Association's 56th annual high blood pressure research conference, scientists at Vanderbilt University reported that drinking water may really help prevent fainting. By monitoring the blood pressure and heart rate, study participants were tilted upright and brought to the point where they almost fainted.
"If they had not had water they were much morr likely to pass out or to have a big drop in blood pressure and heart rate. If we gave them water first we often prevented that response and made it easier for the cardiovascular to do its job during upright tilt keeping blood flow going to the brain. So water proved very effective in preventing fainting," says David robertson, M.D., of Vanderbilt University.
So the study concludes that if you're concerned about standing up for long periods of time or are reluctant to donate blood because you think you might faint drinking a 16 ounce glass of water could make all the difference. By the way, this study was done on healthy individuals, if you are fainting frequently, that may be caused by some other problem and you should talk to your doctor about it.
