Q & A
What is coronary artery disease (CAD)?
-Coronary artery disease, also known as CAD, is a condition that affects the heart and is the most common heart disease in the United States. It occurs when coronary arteries struggle to supply the heart with enough blood, oxygen, and nutrients, often due to cholesterol deposits or plaques that narrow the arteries.
What is the primary cause of CAD?
-The primary cause of CAD is the buildup of cholesterol deposits or plaques in the coronary arteries, which narrows the arteries and decreases blood flow to the heart.
Why might someone not be aware they have CAD until there's a problem?
-CAD typically develops over a long period of time, and its symptoms may not be apparent until there is a significant issue, such as a blockage in the arteries.
What is atherosclerosis and how is it related to CAD?
-Atherosclerosis is the process where fats, cholesterols, and other substances gather along the walls of the arteries. It is usually not a cause for concern, but excessive buildup can lead to blockages and obstruct blood flow, which can contribute to CAD.
Who is generally at a greater risk for developing CAD?
-Men are generally at a greater risk for developing CAD, but the risk for women increases after menopause. Age, existing health conditions, and lifestyle factors also play a role in the risk of developing CAD.
What are some lifestyle factors that can increase the risk of CAD?
-Lifestyle factors that can increase the risk of CAD include physical inactivity, long periods of stress, an unhealthy diet, and smoking.
What are some early signs and symptoms of CAD?
-Early signs and symptoms of CAD may include chest pain or pressure, tightness in the chest known as angina, shortness of breath, and extreme fatigue during activities.
What medical tests might be used to diagnose CAD?
-Medical tests that might be used to diagnose CAD include an electrocardiogram (ECG), an echocardiogram, a stress test, cardiac catheterization and angiogram, or a cardiac CT scan.
How can CAD be treated?
-CAD can be treated by making lifestyle changes such as eating healthier, exercising regularly, losing excess weight, reducing stress, and quitting smoking. In some cases, treatment may involve medications like aspirin, cholesterol-modifying medications, beta-blockers, or medical procedures like angioplasty or coronary artery bypass surgery.
What are some ways to manage and live with CAD?
-To manage and live with CAD, one can reduce cholesterol, lower blood pressure, quit tobacco, eat healthier, exercise, and manage stress. Education and seeking information about the condition can also be beneficial.
Where can I find more information about CAD?
-For more information about CAD, you can watch related videos or visit the Mayo Clinic's official website at Mayoclinic.org.

Transcripts
I'm Dr. Stephen Kopecky,
a cardiologist at Mayo Clinic.
In this video, we'll cover the basics of
coronary artery disease. What is it?
Who gets it? The symptoms,
diagnosis and treatment.
Whether you're looking for answers for
yourself or someone you love,
we're here to give you
the best information available.
Coronary artery disease, also called CAD,
is a condition that affects your heart.
It is the most common heart disease
in the United States.
CAD happens when
coronary arteries struggle to supply
the heart with enough blood,
oxygen and nutrients.
Cholesterol deposits, or plaques,
are almost always to blame.
These buildups narrow your arteries,
decreasing blood flow to your heart.
This can cause chest pain,
shortness of breath or even a heart attack.
CAD typically takes a long time to develop.
So often, patients don't know
that they have it until there's a problem.
But there are ways to prevent
coronary artery disease,
and ways to know if you're at risk
and ways to treat it.
Anyone can develop CAD.
It begins when fats, cholesterols
and other substances gather
along the walls of your arteries.
This process is called atherosclerosis.
It's typically no cause for concern.
However, too much buildup can lead
to a blockage, obstructing blood flow.
There are a number of risk factors,
common red flags, that can contribute to this
and ultimately lead to
coronary artery disease.
First, getting older can
mean more damaged and narrowed arteries.
Second, men are generally at a greater risk.
But the risk for women
increases after menopause.
Existing health conditions matter, too.
High blood pressure can
thicken your arteries,
narrowing your blood flow.
High cholesterol levels can
increase the rate of plaque buildup.
Diabetes is also associated with higher risk,
as is being overweight.
Your lifestyle plays a large role as well.
Physical inactivity,
long periods of unrelieved stress in
your life, an unhealthy diet
and smoking can all increase your risk.
And finally, family history.
If a close relative was
diagnosed at an early age with heart disease,
you're at a greater risk.
All these factors together can paint
a picture of your risk for developing CAD.
When coronary arteries become narrow,
the heart doesn't get
enough oxygen-rich blood.
Remember, unlike most pumps,
the heart has to pump its own energy supply.
It's working harder with less.
And you may begin to notice these signs and symptoms
of pressure or
tightness in your chest.
This pain is called angina.
It may feel like somebody
is standing on your chest.
When your heart can't pump
enough blood to meet your body's needs,
you might develop shortness of
breath or extreme fatigue during activities.
And if an artery becomes totally blocked,
it leads to a heart attack.
Classic signs and symptoms of a heart attack
include crushing, substernal chest pain,
pain in your shoulders or arms,
shortness of breath, and sweating.
However, many heart attacks have minimal or
no symptoms and are found later
during routine testing.
Diagnosing CAD starts by
talking to your doctor.
They'll be able to look
at your medical history,
do a physical exam
and order routine blood work.
Depending on that, they may
suggest one or more of the following tests.
An electrocardiogram, or ECG,
an echocardiogram,
or soundwave test of the heart,
stress test, cardiac catheterization and
angiogram, or a cardiac CT scan.
Treating coronary artery disease
usually means making
changes to your lifestyle.
This might be eating healthier foods,
exercising regularly, losing excess weight,
reducing stress or quitting smoking.
The good news is these changes
can do a lot to improve your outlook.
Living a healthier life
translates to having healthier arteries.
When necessary, treatment could
involve drugs like aspirin,
cholesterol-modifying medications,
beta-blockers, or
certain medical procedures like
angioplasty or
coronary artery bypass surgery.
Discovering you have coronary
artery disease can be
overwhelming. But be encouraged.
There are things you can do to
manage and live with this condition.
Reducing cholesterol,
lowering blood pressure, quitting tobacco,
eating healthier, exercising and
managing your stress can
make a world of difference.
Better heart health starts
by educating yourself.
So don't be afraid to
seek out information and
ask your doctors about
coronary artery disease.
If you'd like to learn even
more about this condition,
