Transcript Heart Disease- The Silent Killer

Fetal Heart Circulation
Before birth, blood from the fetal heart that is destined for
the lungs is shunted away from the lungs through a short
vessel called the ductus arteriosus and returned to the aorta.
When this shunt is open, it is said to be a patent ductus
arteriosus (PDA). The PDA usually closes at or shortly after
birth, allowing blood to course freely to the lungs
.
Foramen ovale- in the fetal heart, a shunt from the right
atrium to left atrium

Heart Murmur
Irregular heartbeat caused by increased in
blood flow to the heart
 an abnormal sound of the heart
 sometimes a sign of abnormal function of
the heart valves.

Arrythmia


irregular heartbeat

working properly, making the heart beat too fast/slow or
inconsistently

Pacemaker
A pacemaker is a small device, about the
size of a pocket watch, that's placed under
the skin near your heart to help control your
heartbeat.
 Arrhythmias

 the
heart's rhythm is abnormal

Heart Disease- The Silent Killer
What is Heart Disease?
A general term that covers a number of
diseases which affect the heart, including
coronary artery disease, heart-failure and
angina.
 Heart Disease is the number one killer in the
United States.

Atherosclerosis and Arteriosclerosis

Arterioslcerosis
 Hardening

of the arteries
Atherosclerosis
 Atherosclerosis
is a specific type of
arteriosclerosis, but the terms are sometimes
used interchangeably. Atherosclerosis isthe
buildup of fats and cholesterol in and on your
artery walls (plaques), which can restrict blood
flow.

Coronary Artery Disease
Occurs when the coronary arteries that
supply the heart muscle become blocked.

Partially blocked it causes angina.

Fully blocked it causes a myocardial
infarction or a heart attack!
Myocardial Infarction
or
Heart Attack
Symptoms: uncomfortable pressure,
fullness, squeezing pain, pain spreading to
the shoulders, neck and arms.
 Chest discomfort and light headedness
 Anxiety/nervousness
 Paleness or pallor
 Increased irregular heart rate

Myocardial Infarction contd.

Feeling of impending doom
If you or someone you know is having these
symptoms call 911!

Angioplasty and Stenting

Angioplasty
 procedure
for expanding arteries that have
become blocked

Stenting
 small
mesh tube that's used to treat narrow or
weak arteries
