Heart disease involves various conditions affecting the heart and blood vessels, primarily caused by atherosclerosis, which narrows arteries due to plaque buildup. Symptoms can range from no discomfort to chest pain or heart attacks, with treatment options including lifestyle changes and surgery. Key prevention tips include maintaining a healthy lifestyle, managing blood pressure and cholesterol, and being informed about personal health risks.

of which are related to a process called atherosclerosis.
relates to the heart.
relates to the veins and arteries.
 is a condition that develops when a
substance called plaque builds up in the walls of the
arteries This buildup narrows the arteries, making it
harder for blood to flow through. If a blood clot forms,
it can stop the blood flow.

4. TYPES OF HEART DISEASE :
 Coronary artery disease
 Heart attack
 Arrhythmias
 Hole in heart

5.  The usual cause is the buildup of plaque.
This causes coronary arteries to narrow,
limiting blood flow to the heart.
 Coronary artery disease can range from
no symptoms, to chest pain, to a heart
attack.
 Treatments include lifestyle changes,
medications, angioplasty and surgery.
• Can have no symptoms, but people
may experience:
• Pain areas: in the chest
• Pain types: can be burning in the chest
• Gastrointestinal: nausea or vomiting
• Heart: fast heart rate or heart attack
• Also common: shortness of breath or
sweating

7.  A heart attack is a medical emergency. A heart
attack usually occurs when a blood clot blocks blood
flow to the heart. Without blood, tissue loses
oxygen and dies.
 Symptoms include tightness or pain in the chest,
neck, back or arms, as well as fatigue,
lightheadedness, abnormal heartbeat and anxiety.
Women are more likely to have atypical symptoms
than men.
 Treatment ranges from lifestyle changes and
cardiac rehabilitation to medications, stents and
bypass surgery.

8.  Symptoms include tightness or pain in the chest, neck, back or arms, as well as
fatigue, lightheadedness, abnormal heartbeat and anxiety. Women are more
likely to have atypical symptoms than men.
 Pain types: can be burning in the chest, crushing, like a clenched fist in the
chest, radiating from the chest, sudden in the chest, or mild
 Pain circumstances: can occur during rest
 Whole body: dizziness, fatigue, light-headedness, clammy skin, cold sweat, or
sweating
 Gastrointestinal: indigestion, nausea, or vomiting
 Chest: discomfort, fullness, or tightness
 Neck: discomfort or tightness
 Arm: discomfort or tightness
 Also common: anxiety, feeling of impending doom, sensation of an abnormal
heartbeat, shortness of breath, or shoulder discomfort

9.  An arrhythmia (ah-RITH-me-ah) is a problem
with the rate or rhythm of the heartbeat.
During an arrhythmia, the heart can beat too
fast, too slow, or with an irregular rhythm.
 A heartbeat that is too fast is called
tachycardia (TAK-ih-KAR-de-ah). A heartbeat
that is too slow is called bradycardia (bray-
de-KAR-de-ah).
 Most arrhythmias are harmless, but some can
be serious or even life threatening. During an
arrhythmia, the heart may not be able to
pump enough blood to the body. Lack of blood
flow can damage the brain, heart, and other
organs
