Introduction:
3Anas Bahnassi PhD CDM CDE
• Cardiovascular disease has been leading
killer since 1900.
• Accounts for 1 of every 3 deaths
You can help reduce deaths by:
• Encouraging healthy life-style
• Early access
• More CPR training of laypeople
• Public access to defibrillation devices
• Recognizing need for advanced life
support (ALS)
Cardiovascular System:
• Heart’s job is to pump blood to
supply oxygen-enriched red blood
cells to tissues.
• Divided into left and right sides
• Atria receives incoming blood, and
ventricles pump outgoing blood.
• One-way valves keep blood flowing
in the proper direction.
• Aorta, body’s main artery, receives
blood ejected from left ventricle.

Pulse:
A pulse is felt when blood passes through
an artery during systole.
– Peripheral pulses felt in the extremities
– Central pulses felt near the body’s trunk

Chest pain:
• Usually results from
ischemia: a decreased
blood flow.
– Ischemic heart
disease involves a
decreased blood flow
to one or more
portions of the heart.
– If blood flow is not
restored, the tissue
dies
Atherosclerosis :
• Usually results from
ischemia: a decreased
blood flow.
– Ischemic heart
disease involves a
decreased blood flow
to one or more
portions of the heart.
– If blood flow is not
restored, the tissue
dies
Thrombo-embolism:
• A blood clot floating through blood vessels.
• If clot lodges in coronary artery, acute
myocardial infarction (AMI) results.
Coronary Artery Disease (CAD):
• The leading cause of death
• Controllable AMI risk factors:
– Cigarette smoking, high blood
pressure, high cholesterol, high
blood glucose level (diabetes),
lack of exercise, and stress
Coronary artery
• Uncontrollable AMI risk factors:
Older age, family history, and being a male
• Acute coronary syndrome (ACS) is caused by
myocardial ischemia.
• Angina pectoris
• Acute myocardial infarction
Angina Pectoris:
• Partial blocking of coronary artery.
• It occurs when the heart’s need for oxygen
exceeds supply.
– Crushing or squeezing pain
– Does not usually lead to death or permanent
heart damage
– Should be taken as a serious warning sign
• Unstable angina
– In response to fewer stimuli than normal
• Stable angina
– Is relieved by rest or nitroglycerin
• Treat angina patients like AMI patients.
Acute Myocardial Infraction (AMI):
• AMI pain signals actual death of cells in heart muscle.
– Once dead, cells cannot be revived.
– “Clot-busting” (thrombolytic) drugs or angioplasty within 1 hour
prevent damage.
– Immediate transport is essential.
• Signs and symptoms of AMI
– Weakness, nausea, sweating
– Chest pain that does not change
– Lower jaw, arm, back, abdomen, neck pain
– Irregular heartbeat and syncope (fainting)
– Shortness of breath (dyspnea)
– Pink, frothy sputum
– Sudden death
Acute Myocardial Infraction (AMI):
• Three serious consequences of AMI:
– Sudden death
• Resulting from cardiac arrest
– Cardiogenic shock
• Often caused by heart attack
• Heart lacks power to force enough blood through
circulatory system
• Inadequate oxygen to body tissues causes organs
to malfunction
– CHF
• Often occurs a few days following heart attack.
Hypertensive emergencies:
– Systolic pressure greater than 160 mm Hg
• Common symptoms
– Sudden, severe headache
– Strong, bounding pulse
– Ringing in the ears
– Nausea and vomiting
– Dizziness
– Warm skin (dry or moist)
– Nosebleed
• If untreated, can lead to stroke or dissecting
aortic aneurysm.
• Transport patients quickly and safely.
Aortic Aneurysm:
• A weakness in the wall of the aorta.
– Susceptible to rupture
– Dissecting aneurysm occurs when inner
layers of aorta become
– Primary cause: uncontrolled hypertension
– Signs and symptoms
• Very sudden chest pain
• Comes on full force
• Different blood pressures
– Transport patients quickly and safely.
Primary Assessment:
• Scene Safety:
– Ensure scene safety and safe access to the patient.
– Standard precautions should include a minimum of gloves.
– Determine the number of patients.
– ALS should be requested.
– Assess the need for additional resources.
• Mechanism of Injury (MOI)/Nature of Illness (NOI):
– Clues often include report of chest pain, difficulty breathing,
loss of consciousness.
– Obtain clues from dispatch, the scene, patient, bystanders.
Scene Size-up
Primary Assessment:
• Observe overall appearance of the patient, age, body position, and
responsiveness.
• Observe work of breathing and circulation.
– Pale skin and cyanosis are indicators of poor perfusion.
• Determine the level of consciousness using the AVPU scale.
– Is the patient calm or anxious? Is the patient able to speak in full sentences?
• Identify immediate threats to life.
• Determine priority of care based on the MOI/NOI.
• If the patient is unconscious, determine whether CPR is needed.
• If the patient has a poor general impression, call for ALS assistance.
• A rapid visual examination will help you identify and manage life threats.
Form a general impression:
Primary Assessment:
• Ensure the airway is open, clear, and self-maintained.
• A patient with an altered level of consciousness may need
emergency airway management; consider inserting a properly sized
oropharyngeal airway.
• If difficulty breathing: apply oxygen via nonrebreathing mask; if not
breathing: give 100% oxygen via bag-mask device.
• CHF patients: use CPAP.
Airway and Breathing:
Primary Assessment:
• Check skin color, temperature, condition.
Circulation:
Transport decision:
• Transport in a stress-relieving manner.
Primary Assessment:
• Investigate the chief complaint (eg, chest pain, difficulty
breathing).
– Ask about recent trauma.
• Obtain a SAMPLE history from a conscious patient.
History taking:
O
P
Q
R
S
T
Primary Assessment:
• Focus on cardiac and respiratory systems.
– Circulation
– Respirations.
Physical Examination :
Vital Signs:
• Obtain a complete set of vital signs
• If available, use pulse oximetry
Primary Assessment:
• Reassess vital signs every 5 min or when patient’s
condition changes significantly.
• Sudden cardiac arrest is always a risk
Reassessment:
Interventions:
• Give oxygen.
• Assist unconscious patients with breathing.
• Follow local protocol for administration of low-dose
aspirin or prescribed nitroglycerin
• If cardiac arrest occurs, perform CPR
Primary Assessment:
• Reassess your interventions.
• Provide rapid patient transport.
Interventions :
Communication and documentation:
• Alert emergency department about patient condition
and estimated time of arrival.
• Report to hospital while en route.
• Document assessment and interventions
