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.
