...form, is lost to digestive processes and removed by the liver, and what remains can irritate the intestinal tract. Enter transdermal patches. First designed to treat motion sickness, they slowly deliver drugs through the skin from a reservoir within the patch, and are being used increasingly to treat hypertension, angina and other disorders. So far, the patches are limited to carrying small-molecule drugs that can diffuse through the skin. But several teams are experimenting with electrical or ultrasonic devices that can also push larger-molecule drugs through the skin or create temporary macropores through which these bulky molecules...
...trick with heart attacks is to know what to look for, and that's not always easy. Cheney experienced the classic chest pains called angina--usually described as a squeezing pain that starts in the center of the chest and can radiate to the shoulders, neck, arms or back. Angina is the body's way of telling you that your heart is being starved; the heart muscle is screaming for the oxygen-rich blood that's not getting through a blocked or constricted coronary artery...

Fully one-third of all heart-attack victims feel no muscle pain at all, according to a study published in the Journal of the American Heart Association last summer. Their most common symptom is extreme shortness of breath or difficulty in breathing. Other signs include nausea, profuse sweating, lightheadedness, fainting, palpitations or unexplained anxiety...

Avoid any physical exertion that could put more stress on your heart. If heart disease or angina has previously been diagnosed, you may have medications such as nitroglycerin on hand. A nitroglycerin tablet placed under the tongue can provide quick relief by opening narrowed coronary arteries as well as other blood vessels throughout the body. Many doctors instruct patients to chew an aspirin, which thins the blood and helps...
