Coronary artery disease and its resulting conditions of angina pectoris and myocardial infarction are discussed. Coronary artery disease occurs when plaque builds up in the coronary arteries, limiting blood flow to the heart. Angina pectoris, commonly known as chest pain, occurs when oxygen demand of the heart exceeds supply and has types including stable, unstable, and variant angina. Myocardial infarction, or heart attack, happens when an area of heart muscle dies due to lack of oxygen from a blockage of one of the coronary arteries. Nursing care focuses on pain management, preventing complications, health education, and cardiac rehabilitation.
Heart failure (HF) is a common cardiovascular condition with increasing incidence and prevalence. Unlike western countries where heart failure is predominantly a disease of elderly, in India it affects younger age group. Heart failure is a chronic condition in which the heart cannot pump enough blood and oxygen to support other organs in your body.
Angina pectoris is a medical condition resulting in chest pain or discomfort. Angina pectoris occurs when the heart is not getting enough blood supply. the pain related to angina is temporary, but if left untreated can make serious heart complications inevitable.
Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw.

Angina also known as angina pectoris is a medical condition characterized by chest pain usually left sided due to inadequate blood supply (ischemia) to the heart muscles due to obstruction (like presence of blood clot), narrowing or contraction (vasospasm) of the supplying coronary arteries.

Definition:
Angina: Choking or suffocation.
Pectoris: Chest.
Angina pectoris, is the medical term
used to describe acute chest pain or
discomfort.
Angina occurs when the heart’s need
for oxygen increases beyond the
level of oxygen available from the
blood nourishing the heart.
It has 3 types
Stable Angina

resting angina) :08/21/17

Types of Angina
Stable angina:
People with stable angina have
episodes of chest discomfort
that are usually
predictable. That occur on
exertion or under mental or
emotional stress.
Normally the chest discomfort
is relieved with rest,
nitroglycerin (GTN) or both.
It has a stable pattern of
onset, duration and intensity
of symptoms.

Unstable angina:
It is triggered by an un
predictable degree of
exertion or emotion.
(progressive), more
severe than stable.
Characterized by
increasing frequency &
severity. Provoked by less
than usual effort,
occurring at rest &
interferes with pt
lifestyle.

Variant Angina
(Prinzmetal’s or resting
angina) :
occur spontaneously with no
relationship to activity.
Occurs at rest due to spasm.
Pt discomfort that occurs
rest usually of longer
duration. Appears to by
cyclic & often occurs at
about the same time each

14. Myocardium Infarction
Myo means muscle, “Cardiac”
heart, infarction means “death
of tissues due to lack of blood
supply”.
It is also called heart attack.
It occurs when coronary
arteries become blocked and
the part of myocardial
muscles become dead due to
prolonged lack of oxygen
supply to the muscle cells.

15. PATHOPHYSIOLOGY
Coronary artery cannot supply enough blood to the
heart in response to the demand due to CAD
Within 10 seconds myocardial cells experience ischemia
Ischemic cells cannot get enough oxygen or glucose
Ischemic myocardial cells may have decreased
electrical & muscular function
Cells convert to anaerobic metabolism.
Cells produce lactic acid as waste
Pain develops from lactic acid accumulation
Pt feels anginal symptoms until receiving demand

are chest pain radiating to neck,

21. IMPORTANT INFORMATION TO
REMEMBER
Increase supply of
Oxygen
Decreasing the demand of
Oxygen:
• Stop activity and lie down
(CBR)
•Take Tab. Angisid sublingually
and wait till it dissolves.
If pain continues take up to 03
Tab. Angisid one every five
minutes. If pain is not relieved
yet take another tab. and rush to
EMERGENCY services.

22. IMMEDIATE MANAGEMENT OF MI:
GOALS:
To prolong life.
Minimize infarct size.
Reverse ischemia.
Reduce cardiac work.
Prevent and treat complications.
A) INITIAL TREATMENT:
Rapid triage.
OMI (oxygen, monitor and I/V line).
Check vital signs and O2 saturation.
ECG within 10 minutes and repeat ECG.
Blood samples for enymes, CBC, lytes, and lipid
profile.

Ineffective coping R/T effects of acute illness and
major changes in life style
Impaired gas exchange related to ineffective
breathing pattern and decreased systemic tissue
perfusion.
Anxiety related to present status and unknown

Cardiac rehabilitation provides a venue for
continued education, re-enforcement of lifestyle
modification, and adherence to a comprehensive
prescription of therapies for recovery from MI,
which includes exercise training
Goals of Rehabilitation program:
Develop a program for progressive physical
activity
Lives as full, vital and productive life
Remain within the limits of the heart’s ability to
respond to increases in activity and stress.
