Heart Disease Risk Factors
What every person should
know about heart disease
- Risk factors for coronary artery disease
The Framingham Heart Study, a 50-year study in
Framingham, Massachusetts, developed the concept of risk factors and
their relationship to coronary artery disease-a concept that is widely
accepted and used throughout the world.
- Atherosclerosis and coronary artery disease
Atherosclerosis is the buildup of fatty, fibrous
plaques on the inner wall of arteries causing them to become narrowed or
hardened. Atherosclerosis starts as a fatty streak and develops over
time to become a complicated obstructive lesion that blocks blood flow.
Early fatty streaks have been seen at autopsy in very young children
(under 10) who have died accidentally. Significant atherosclerosis has
been seen in young men in the military who have died in combat. From
this, we know that atherosclerosis starts at a very young age and
develops silently and slowly without symptoms or warning.
Atherosclerosis of the
coronary arteries can develop in any of the main coronary arteries or
any of their many branches. Atherosclerosis of the coronary arteries is
called coronary artery disease or CAD.
The
Risk Factors
There are two types of risk factors for the
development of coronary artery disease - those you cannot control and those
you can.
The "uncontrollable" risk factors are:
- Age (the risk increases
with age)
- Gender (men develop CAD
10 years earlier than women)
- Family history (genetic
predisposition and common lifestyles increase risk)
- Race (incidence is
greater in some groups of African Americans, Hispanics, Asian Americans,
native American Indians,)
The "controllable" risk factors are:
- Smoking
- High blood pressure
- High blood cholesterol
- High blood sugar
(diabetes)
- Obesity and
overweight
- Obesity and Overweight
- Physical inactivity
- Stress
Unfortunately, many people tend to ignore the
importance of the "uncontrollable" risk factors because they feel they can
do nothing about them. While it is true that you cannot change your age,
gender, race, or the family you were born into, these risk factors
compound and worsen the impact of the other risk factors.
Remember-the first symptom which 30% of heart
attack victims experience is sudden death. It is a dangerous game of
Russian roulette with your life if you wait for symptoms to appear before
you take action.
And the only action you can
take is to identify and reduce the "controllable" risk factors.
