What is Heart Disease?
 Heart disease also known as cardiovascular disorder, a term that
includes a number of different diseases which affect the heart
 Coronary artery disease (CAD) due to atherosclerosis is the most
common cause of heart disease in developed as well as developing
nations. CAD is the narrowing or blockage of the coronary arteries
which supply blood to the heart muscle; atherosclerosis occurs when
fatty material and a substance called plaque builds up in the walls of
the arteries
 Other causes of heart disease include hypertension (high blood
pressure), abnormal heart valve function, abnormal heart rhythm,
weakening of the pumping ability of the heart (heart failure) which
may be caused by progressive atherosclerosis, uncontrolled HTN,
valve disease, infection, or toxins

What is Coronary Artery Disease?
 CAD develops when the arteries that supply blood to heart muscle
become hardened & narrowed due to the buildup of cholesterol & fat
into plaque in the inner lining of the walls of the arteries, obstructing
normal blood flow
 As the buildup grows, less blood can flow through the arteries
resulting in the heart muscle not being able to get blood, nutrients,
and oxygen it needs to continue pumping effectively
 This can lead to chest pain (angina) or a heart attack (MI); most heart
attacks happen when a plaque ruptures causing a blood clot to form
which suddenly and totally cuts off the hearts' blood supply, causing
permanent heart muscle damage and less often sudden cardiac death.

Symptoms of Coronary Artery Disease (Angina Pectoris)
Cold weather and cigarette smoking are 2
precipitants of a heart attack via 2 different
mechanisms: cold causes coronary artery
spasm (constricted coronary arteries), while
cigarettes cause the blood to coagulate more
readily thus increasing clot formation within
the coronary artery.

What is a Stroke?
A stroke is the rapidly developing loss of
brain functions due to a disturbance in the
blood vessels supplying blood to the brain
ABB MD FACC©
What is a Heart Attack?
 Over time, CAD (repeated heart attacks or
unstable angina) can also weaken the heart
muscle and contribute to heart failure and
arrhythmias
 It is difficult to estimate exactly how common
heart attacks are because as many as 200,000
to 300,000 people in the U.S. die each year
before medical help is sought or medical help
arrives (mortality rate: 200,000-300,000)
 Approximately 1 million patients visit the
hospital each year with a heart attack
 ~ 1 death out of every 5 deaths (20%) are due
to a heart attack
Without proper lifestyle and
care, some day you may be
right the first time!!!
