...heart. So it came as a surprise last week when a study published in the Journal of the American Medical Association reported that, contrary to earlier beliefs, taking fish-oil supplements did not reduce the risk of serious abnormal heart rhythms, the kind responsible for sudden cardiac death. You might be tempted to seize on this finding as yet another failure of a popular dietary supplement to protect health. That would be a mistake, because the study is of limited relevance to the general population. The benefits of fish oil are well established, not just for heart health but also...
...health-promoting effects of EPA and DHA have little or nothing to do with preventing abnormal cardiac rhythms. Their most important actions are reducing inflammation, reducing the clotting tendency of the blood, improving the profile of fats circulating in the blood, optimizing brain function (DHA is a major constituent of cell membranes in the central nervous system) and inhibiting abnormal cell proliferation, thereby reducing cancer risks. All of this translates into significant disease protection...
...emergency resuscitation team response. Different hospitals use different names; some use numbers, some colors, but they are all ways of instantly telling the people who work there, without scaring patients and visitors, that there's an emergency. Code red is typically a fire in the hospital; code blue is cardiac arrest. I was three weeks out of medical school, a brand new surgical intern (that is, a first-year resident) at the Brigham and Women's Hospital in Boston, when my days and nights began to be punctuated by the heady rush of codes...
...Mystery of the Double Cardiac Arrest Even surgical residents used to the heady rush of "codes" occasionally encounter emergencies that throw them for a total loop
...bedside table was a familiar yellow and red tube and it was almost empty. Nitropaste is a transcutaneous cardiac nitrate - a form of the more familiar 'nitroglycerin' that heart patients put under the tongue to relieve anginal chest pains. They both work by opening up certain blood vessels. Because it is well absorbed through the skin, it's given by squeezing a little out - like a half-inch long squeeze of toothpaste - onto a piece of paper or plastic and sticking it onto the patient's skin. Patients usually can do this for themselves - that's why it was left...
