NEW THERAPY FOR HEART ATTACKS

NEW THERAPY FOR HEART ATTACKS



New drugs can stop or limit the damage of a heart attack, but only if the patient gets help immediately, experts say. Once the flow of blood to a portion of the heart is blocked for several hours, the damage is irreversible.


Knowing the symptoms of a heart attack, which can be wide-ranging and confusing, is extremely important. So is knowing risk factors, such as obesity, diabetes, high blood pressure and family history.


Typical symptoms of a heart attack include a crushing pain in the chest, sweating, difficulty breathing, weakness and pain in the arms, particularly the left. Symptoms one could attribute to something else can cause devastating delays in seeking treatment. These include feelings of indigestion, back shoulder and neck pain and nausea. Early signs of trouble may appear during physical activity and disappear with rest. Any numbness of tingling of the fingers or toes, dizziness, shortness of breath or difficulty in breathing should not be ignored.


Clinical studies, laboratory investigations and a number of surveys show certain personal characteristics and life-styles pointing to increased danger of heart attack. These danger signs are called "risk factors." These well established risk factors are high blood pressure, high blood cholesterol, cigarette smoking and diabetes mellitus.
Attempts at modifying risk factors most certainly have contributed to the declining death rate from heart attacks in the United States.
During the 1960's, U.S. death rates from heart attacks were still rising, but today's figures show that heart attacks have fallen dramatically. And, overall, heart-related problems have declined about 25 percent in the last decade. This decrease undoubtedly is due to better medical care of heart attack victims, but it is likely that a sizable percentage is related to modification of risk factors.


Medical technology is advancing at an increasingly rapid rate. More drugs and medical technology are available than ever before and the entire population is now more aware of the seriousness of heart attacks. There has been an increased interest in learning CPR and many community organizations now offer this valuable training.
Of particular concern by doctors and researchers is the role that the American diet plays in the health of one's heart. Obesity predisposes individuals to coronary heart disease. Some of the reasons for this are known, but others are not. The major causes of obesity in Americans are excessive intake of calories and inadequate exercise. When caloric intake is excessive, some of the excess frequently is saturated fat, which further raises the blood cholesterol. Thus, obesity contributes to higher coronary risk in a variety of ways.


Many of the major risk factors for a heart attack are silent and much of the responsibility for their detection lies with each of us as individuals. Regular checkups are particularly necessary if there is a family history of heart attacks of heart disease, high blood pressure, high cholesterol levels or diabetes.

GROWING OLD GRACEFULLY

Today the average duration of human life in the United States is just about 70 years for women and a little less for men. Conservative experts believe that man is really build to last about 100 years; and that medial advances and more healthful living habits could bring this about within a generation or two.


What good is it to add years to life if we do not also add life to years? In fact, unless people learn to enjoy life and to grow old gracefully, the extra years may be an additional burden.


From 18 to 30 years is roughly the period of highest physical and mental vigor. The experiences we accumulate from the day we are born help us to conserve and to use our physical and mental abilities more wisely, so that for some time after 30 years we are able to perform increasingly well in spite of slowly slipping vigor. After age 50 the increasing accumulation of experience is no longer able to offset the now more rapidly energy and therefore aging begins to assert itself noticeably and in many ways.


A number of things may come about gradually such as people who have not used eyeglasses before may at some time in their forties need them for reading, and in the fifties they usually need bifocals.


Also in the forties, people are likely to put on weight because there is a general slowdown in the oxidation rate of the aging body tissue. Also we tend to do less strenuous work with no reduction
in the amount of food consumed.

And in the fifties there is likely to be some loss of hearing. Usually the high-pitched tomes go first, so words with the sounds of F, S, and TH are confused. A hearing aid may be needed in some cases.


Aging is generally accompanied by a loss in physical and mental flexibility. This is noticed in a tendency to become stiff in the joints; in slower comeback after a strenuous trip, excessive "night life," or hard work; in slower healing of wounds, sore muscles, and sprains; in slower recovery of pep after an illness; and in greater difficulty to adjust to new people, new places, and new ideas.


Men, especially, will notice loss of muscular strength. There will be increased unsteadiness and delicate muscle movements will be more clumsy and the stride in waking will become shorter. The conclusion now is that the performance and ability of the elderly has long been underestimated and can be greatly improved by a proper diet, sleep and exercise along with rest and relaxation.


Many elderly people tend to lose their joy and will to live and chronic worriers may mope around and withdraw. Medical authorities now say that laughter is one of the best medicines for the elderly. You can always keep your sense of humor tuned up by surrounding yourself with pleasant and interesting people. Just act your age and don't be afraid to laugh at yourself even when no else is around.


Now that we all know the role that physical activity plays in our lives, remember to do something physical every day. The joints must be used or quite simply they will tighten with age creating that stooped worn out appearance we so often associate with getting old. Keep yourself flexible and fit on an exercise program consistent with your ability.
