A patient has narrowing of the coronary arteries caused by plaque
accumulation. Identify the cardiovascular disorder represented by this
finding. -ANSWER- Coronary artery disease (CAD) is the disorder
represented by this finding. CAD develops when plaque accumulates
within the coronary arteries, reducing the space available for blood
flow and potentially limiting oxygen delivery to the myocardium.
The myocardium requires an adequate supply of oxygenated blood at
all times. Identify the condition that develops when coronary
circulation cannot meet this requirement. -ANSWER- Myocardial
ischemia develops when the coronary circulation cannot provide
sufficient oxygenated blood to meet the metabolic needs of the
myocardium. The condition may occur when coronary arteries are
narrowed or obstructed.
A patient reports predictable chest pressure during strenuous activity
that resolves after resting. Which cardiovascular condition best
corresponds with this clinical pattern? -ANSWER- Stable angina best
corresponds with this pattern. Stable angina occurs when myocardial
oxygen demand increases, commonly during exertion, but narrowed
coronary arteries cannot provide enough additional blood flow.
Symptoms typically improve when the cardiac workload decreases.
,Chest discomfort has recently become more frequent and begins
occurring even while the patient is resting. Identify the form of angina
suggested by this change. -ANSWER- Unstable angina is suggested by
this change. Unlike stable angina, unstable angina may occur at rest or
with minimal exertion and represents a more serious reduction in
coronary blood flow that can precede myocardial infarction.
Prolonged interruption of coronary blood flow results in irreversible
injury to cardiac muscle. Name the resulting condition. -ANSWER-
Myocardial infarction results when prolonged interruption of coronary
blood flow causes irreversible injury and death of myocardial cells. It is
commonly known as a heart attack.
Atherosclerotic plaque has narrowed a coronary artery, but the patient
has not yet experienced permanent myocardial tissue death. Identify
the pathological process currently affecting the heart. -ANSWER- The
heart is experiencing myocardial ischemia. The narrowed coronary
artery is limiting oxygen-rich blood reaching the myocardium, but the
condition has not necessarily progressed to irreversible tissue death.
An EKG technician encounters a patient complaining of pressure,
tightness, and discomfort in the chest. Which cardiovascular emergency
should remain an important consideration? -ANSWER- Acute coronary
syndrome, including myocardial infarction, should remain an important
consideration. Chest pressure or discomfort can result from inadequate
, coronary blood flow, and potentially life-threatening cardiac conditions
require immediate clinical assessment.
A blood clot forms within a vessel and remains attached to the vessel
wall at its original location. Identify this type of clot. -ANSWER- A
thrombus is a blood clot that forms within a blood vessel and remains
at its site of formation. If the clot breaks loose and travels through the
bloodstream, it becomes an embolus.
A clot separates from its original location and travels through the
bloodstream before becoming lodged in another vessel. Identify the
resulting condition. -ANSWER- The traveling material is an embolus. An
embolus can obstruct blood flow when it becomes lodged in a vessel
that is too narrow to allow it to pass.
Plaque within an artery becomes unstable and contributes to the
formation of a clot. Identify the potential consequence if the clot
completely obstructs a coronary artery. -ANSWER- Complete coronary
artery obstruction can cause severe myocardial ischemia and, if the
interruption persists, myocardial infarction. The affected portion of the
heart becomes deprived of oxygenated blood.
The term atherosclerosis is frequently encountered when studying
coronary artery disease. State the underlying pathological change
associated with this condition. -ANSWER- Atherosclerosis involves the
accumulation of fatty material, cholesterol, cellular debris, and other
