Sudden Illnesses
Heart Attack
• Clot in coronary artery blocks blood
supply.
• Blood supply to part of the heart
muscle is reduced or stopped.
• Heart muscle tissue dies.
• Cardiac arrest
• Heart stops if electrical system of
heart is affected.
Recognizing Heart Attack
(1 of 2)
• Chest pressure, squeezing, or pain
that lasts longer than a few
minutes or goes away and comes
back
• Pain spreading to shoulders, neck,
or arms
• Dizziness, sweating, nausea
• Shortness of breath
Recognizing Heart Attack
(2 of 2)
• Not all warning signs occur with every heart
attack.
• Some victims — as many as one third —
have no chest pain.
• Prompt action is important.
• Hospital can administer clot-dissolving
drugs (thrombolytics).
• The sooner this is done, the better.
Care for a Heart Attack (1 of 2)
• Call 9-1-1.
• Monitor breathing.
Give CPR if
necessary.
• Help victim into
comfortable
position.
• If victim has
nitroglycerin, assist
them in taking it.
Care for a Heart Attack (2 of 2)
• Nitroglycerin
• Can relieve chest pain from angina but
not heart attack.
• Dilates coronary arteries, increasing
blood flow to heart muscle.
• Lowers blood pressure
• Caution: Victim should lie down once
nitro is taken.
Angina
• Chest pain from coronary heart
disease
• Heart muscle does not get enough
blood
• Brought on by physical activity, cold
exposure, emotional stress
• Seldom lasts longer than 10 minutes
• Relieved by nitroglycerin
Recognizing Angina
• Signs are similar to heart attack
• Crushing, squeezing pain
• Pain like someone is standing on
victim’s chest
• Lasts 3 to 10 minutes
• Shortness of breath, nausea,
sweating
• Victim feels anxious
Care for Angina
• If victim has nitroglycerin, help
the victim use it.
• If pain lasts longer than 10
minutes, suspect a heart
attack, and call 9-1-1.
• Other causes of chest pain:
• Exercise or injury
• Respiratory infections
• Indigestion
Risk Factors of
