...very sensitive. Any one of us could "fail" such an exam and still not notice a great difference in our daily life. In addition, this is a preliminary study that lacked a control or comparison group. "I think there's something to this," says Dr. Patrick McCarthy, a cardiac surgeon at the Cleveland Clinic. But he is quick to add that it's not at all clear how much of the decline is due to the bypass and how much to aging...
...addition to these physical precautions, there are the health precautions every aging body should take. Physical and eye examinations, with special attention to cardiac and blood-pressure problems, should be performed annually to rule out serious medical conditions. Blood pressure that's too low or an irregular heartbeat can put you at risk for fainting and falling. Don't forget to take calcium and vitamin D, two critical factors in developing strong bones. Finally, enrolling in an exercise program at your local gym can improve agility, strength, balance and coordination--all important skills that can keep you on your feet...
DEFIBRILLATORS Heart patients may rest easier knowing that the cardiac jump-start that might save their life is in the next room. Agilent Technologies, based in Palo Alto, Calif., and CVS.com last year launched Heartstream, the first defibrillator available directly to consumers with a doctor's prescription...
There's more to heart disease, of course, than heart attacks. More and more Americans are developing a condition called congestive heart failure, in which the cardiac muscle becomes weakened and can no longer pump blood efficiently. Investigators are currently studying a group of specialized hormones that are released whenever the heart muscle falters. Some of these hormones help restore the heart's vigor while others, paradoxically, make the muscle stiffer and more difficult to contract. The goal is to figure out a way to boost the levels of the beneficial hormones while lowering those that make the weakened heart...
