Introduction to Coronary Artery Disease
Coronary artery disease (CAD) is caused by atherosclerosis and affects the h
eart by obstructing the supply of oxygenated blood, altering myocardial cell
metabolism and nutrient uptake. The progression of plaque build-up in the ar
teries causes resistance, lessening the ability for oxygenated blood and nutri
ents to flow through, and can lead to myocardial ischemia or infarction.
This learning module focuses on disease processes associated with coronary
artery disease and enables you to meet the following course outcomes:
CO 1: Analyze pathophysiologic mechanisms associated with selected
disease states across the lifespan.
CO 2: Examine the way in which homeostatic, adaptive, and compensa
tory physiological mechanisms can be supported and/or altered throug
h specific therapeutic interventions across the lifespan.
CO 3: Distinguish risk factors associated with selected disease states a
cross the lifespan.
CO 4: Integrate advanced pathophysiological concepts in the diagnosis
and treatment of health problems in selected populations.
Review of the Circulatory System
Complete the following sentences by choosing from the list of options.
The coronary Arteries are blood vessels that provide the major blood supply
to the heart to pump through the circulatory system. Deoxygenated blood
arrives to the right side of the heart and travels to the pulmonary arteries to
release carbon dioxide and obtain oxygen.

Coronary arteries are blood vessels that supply the heart with blood to pump
through the circulatory system. Deoxygenated blood arrives to the right side
of the heart and travels to the pulmonary arteries to release carbon dioxide
(CO2) and obtain oxygen.
Oxygenated blood is then carried from the lungs through the pulmonary
veins to the left side of the heart and flows through the aorta to the body’s
organs.
Hypertension and diabetes mellitus are both pathological risk factors for
CAD.
Atrial fibrillation, heart failure, pneumonia, and gastroenteritis do not cause
CAD.
Cause of Coronary Artery Disease Which of the following statements best
describes the cause of coronary artery disease (CAD)?
A heart arrhythmia or disturbance slows the pumping of the heart, impairing
coronary circulation and reducing oxygenated blood.
A buildup of plaque inside a coronary artery leads to reduced circulation to
the heart.
Higher than normal blood pressure injures the inside of the coronary artery,
causing leakage of blood into the heart muscle.
A clot in the coronary circulation blocks blood movement beyond a specific
point.
Overview of Coronary Arteries
Coronary arteries are blood vessels that supply the heart with blood to pump
through the circulatory system. Blood flows through the coronary arteries, wh
ere deoxygenated blood arrives on the right side of the heart and travels to t
he pulmonary arteries to release carbon dioxide (CO2) and obtain oxygen.
Oxygenated blood is then carried from the lungs through the pulmonary vein
s to the left side of the heart, flowing through the aorta to the body’s organs.
Pathophysiology of Coronary Artery Disease
Coronary artery disease (CAD) is a complex chain of events where
atherosclerotic changes (e.g., plaque accumulation) invade the arteries and
damage the endothelial (inner) layer. Under normal functioning, the

endothelium maintains a balance between vasoconstriction and vasodilation,
preventing platelets from aggregating and controlling fibrin production.
When the endothelium layer becomes damaged, inflammatory processes will
occur. Macrophages attach, setting up phagocytosis; plaque formation and
vasoconstriction occur, marking the beginning of atherosclerosis. As plaque
accumulates, a thrombus, or clot, can form, which disrupts normal blood
flow. With disease progression, myeloid cells can destabilize the plaque in
the arterial wall and cause its rupture, triggering a myocardial infarction (MI)
or stroke.
Cascade of Conditions
Coronary artery disease (CAD) can lead to which of the following
pathophysiological conditions? Select all that apply.
Weakened cardiac muscle
Vasoconstriction
Thrombus formation
Inflammation and plaque accumulation
Inadequate ventilation and perfusion (Ventilation is the movement of air in and out
within the respiratory system (alveoli). )
Coronary Artery Disease and Pathway to Acute Coronary Syndromes
Coronary artery disease (CAD) is the most common type of heart disease and
the leading cause of mortality in the United States (Centers for Disease Contr
ol and Prevention [CDC], 2023). When atherosclerosis reaches a clinically sig
nificant level, chronic stable angina or acute coronary syndrome (ACS) may o
ccur.
ACS may lead to unstable angina or myocardial infarction (MI), which are me
dical emergencies. ACS forms a pathophysiologic continuum, depriving the h
eart muscle of oxygen and essential nutrients for cellular uptake and metabo
lism and interfering with the heart’s pumping ability.
Cardiac Performance
Multiple factors can affect cardiac performance. Coronary artery disease (CA
