Coronary Artery Disease
Transcript of Coronary Artery Disease
Need a visual?
Risk factors include...
What Causes It?
What are the symptoms?
CAD remains the leading cause of
mortality in the United States in men and women of every major ethnic group.
It is known as the most common form of heart disease...
In 2008 it was responsible for 1 in 4
deaths in the same year
Coronary Artery Disease (CAD)
Characterized by atherosclerosis in
the coronary arteries.
Cholesterol progressively accumulates in the the coronary artery lumen:
Who is affected?
(Percent of population -men vs. women with heart disease/complications, by age)
CAD begins with injury to the
inner layer of the coronary
artery. The damage may be
caused by: Smoking, obesity, high blood pressure, high cholesterol diet, diabetes, or radiation therapy for cancer treatment...
A closer look:
-High Blood pressure
-Poor general diet (trans fats)
-Family history of early
Atherosclerosis develops gradually and usually exhibits no symptoms until later stages. The most common symptom experienced with CAD is chest pain, or a pressure sensation, also known as angina.
The most severe and dangerous symptom experienced, is a pulmonary embolism or a myocardial infarction.
Lifestyle & Home Remedies:
-Stop smoking: quitting is the best way to halt the progression of atherosclerosis.
-Exercise most days a week: this helps
lower blood pressure and reduces risk of
-Eat a heart healthy diet: this can help control your weight, cholesterol, blood pressure, and blood sugar.
-Maintain a healthy weight: Losing as few as 5-10 lbs can reduce risk of high cholesterol and diabetes -the two
biggest risk factors in atherosclerosis.
(Complications depend on the location of the blocked arteries):
- Heart failure
- Carotid Artery Disease
- Peripheral Artery Disease
- permanent heart damage due
to a Myocardial Infarction (MI)
Good reasons to maintain a healthy diet:
Will any medication help?
With the help of lifestyle changes, medications will help such as:
(Lower LDL, and raise HDL)
-Anti-platelet medications (coumadin)
-Diuretics (lower blood pressure)
-Calcium channel blockers
What type of treatment is available?
-Angioplasty & stent placement
-Endarterectomy: (Surgical removal
of fatty deposits from arterial walls)
resulting in less blood flow and insufficient oxygen, possibly culminating a Myocardial Infarction (MI).
This could lead to permanent
heart damage (as shown below)
The most severe and dangerous symptom experienced, is a pulmonary embolism or a myocardial infarction...
Just remember to make lifestyle changes one
step at a time, and keep in mind what
lifestyle changes are manageable for
you in the long run
what we eat?
Our intake of certain types of dietary fats influences our risk for heart disease by increasing or decreasing certain blood lipids. Research indicates that high intakes of saturated and
fatty acids increases the blood's level of lipids associated with heart disease.
