Infective Endocarditis (cont.)
• Pathophysiology
• Pathogens, usually bacteria, enter the bloodstream by any of the previously
mentioned means
• The pathogen accumulates on the heart valves and/or the endocardium and forms
vegetations
Slide 59
Infective Endocarditis (cont.)
• Complications
• Heart failure and embolization
• Signs and symptoms
• Fever, chills, malaise, fatigue, and weight loss
• Chest or abdominal pain; may indicate embolization
• Petechiae inside the mouth and on the ankles, feet, and antecubital areas
Slide 60
Infective Endocarditis (cont.)

Slide 63
Pericarditis
• Cause and risk factors
• Inflammation of the pericardium
• May be primary disease or associated with another inflammatory process
• The disease may be acute or chronic
• Acute pericarditis caused by viruses, bacteria, fungi, chemotherapy, or AMI
(Dressler syndrome)
• Chronic pericarditis caused by tuberculosis, radiation, or metastases
Slide 64
Pericarditis (cont.)
• Pathophysiology
• In acute pericarditis, inflammatory process increases amount of pericardial fluid and
inflammation of the pericardial membranes
Slide 65
Pericarditis (cont.)
• Complications
• Pericardial effusion or accumulation of fluid in the pericardial space
• May lead to cardiac tamponade
• Signs and symptoms
• Chest pain
• Most severe on inspiration
Slide 66
Pericarditis (cont.)
• Medical diagnosis
• Serial ECGs
• Echocardiogram
• Creatine kinase-MB fraction (CK-MB)
• Blood cultures
• Medical treatment
TALKING POINTS:
• How can you differentiate the pain of pericarditis with that of angina?

Slide 67
Pericarditis (cont.)
• Assessment
• Assessment of heart sounds especially important
• Interventions
• Rest and reduction of activity

Slide 68
Valvular Disease
• If valves damaged, blood no longer flows in one direction
• Stenosis is narrowing of the valve opening, limiting the amount of blood ejected from one
chamber to the next
Slide 69
Valvular Disease (cont.)
• Mitral stenosis: narrowing of the opening in the mitral valve that impedes blood flow from
the LA into the LV
• Mitral regurgitation: allows blood to flow back into the LA during diastole
• Mitral valve prolapse: one or both leaflets enlarges and protrudes into the LA during
systole
Electrocardiogram Monitoring
• 12-lead electrocardiogram
• Looks at heart from 12 directions or perspectives
TALKING POINTS:
• What cardiac events occur during the P wave, QRS complex, and the T wave?

Slide 71
Electrocardiogram Monitoring (cont.)
• Interpretation of electrocardiograms
• Heart’s electrical activity represented by deflections, positive and negative, from the
baseline
• P wave, QRS complex, and T wave
• Criteria for interpreting electrocardiograms
• Rate calculation
• Rhythm
TALKING POINTS:
Slide 72
Electrocardiogram Monitoring (cont.)
• Interpretation of electrocardiograms
• Normal sinus rhythm
• The most common cardiac rhythm is sinus in origin because the impulse

Hemodynamic Monitoring
• Central venous catheter
• Placed through the skin, into a venous access (brachial, femoral, subclavian, or
TALKING POINTS:
• The pressure in the RA (called right atrial pressure [RAP] or central venous pressure
[CVP]) can be measured.
• This measurement is used as an indication of fluid volume.
• What do measurements below normal indicate? Above normal?

Slide 74
Hemodynamic Monitoring (cont.)
• Pulmonary artery catheter
• Swan-Ganz catheter
• Longer than the central venous catheter
• Inserted like the central venous catheter and is threaded through the RA, tricuspid
TALKING POINTS:
• The purpose of a pulmonary artery catheter is to measure right-sided heart pressures and
pulmonary artery pressures and to assess left-sided heart function.
• What is the normal pulmonary capillary wedge pressure?
Slide 75
Hemodynamic Monitoring (cont.)
• Arterial line
• Provides a direct measurement of systolic and diastolic blood pressures

PRACTICE
• Divide the class into three groups, and
assign each group one of the following
cardiac disorders: coronary artery disease
(CAD), acute myocardial infarction (AMI), or
congestive heart failure (CHF). Have each
group develop a presentation about the
disorder that includes the pathophysiology,
• Divide the class into several teams, and take
turns asking the teams quiz questions
regarding each cardiac disorder in this
lesson. Some example of questions might
be: What are the risk factors associated with
infective endocarditis? What are some
complications of cardiomyopathy? How is
sudden cardiac death treated? The team
with the most correct answers is the winner.
• Divide the class into groups, and present
each group with the following scenario: A

DISCUSS
• Present the image collection PPT slides with
various dysrhythmias and ask students to
identify various dysrhythmias
• Divide the class into groups, and assign
each group a nursing diagnosis from the
textbook that is associated with the
disorders from this lesson. Have each group
develop a list of nursing interventions with
rationales that would be used to meet the
goals. Then have the students discuss their
interventions and rationales with the class.
POST & COMMENT
• Post the following discussion topic online
and have students comment. List at least
five nursing interventions for a patient
experiencing myocardial infarction, heart
failure, infective endocarditis, and valve
disorders. Ask students to prioritize their
interventions. Ask students to post
constructive comments on each other’s
postings.
Critical Thinking Question
A 53-year-old man presents to the emergency department with severe chest pain that has
lasted for the past 2 hours, radiating down his left arm. The pain is unrelieved by sublingual
nitroglycerin given by paramedics en route to the hospital. The patient is overweight and
has a history of hypertension; he is a smoker and has a family history of heart disease. The
provider suspects that the patient is experiencing an acute myocardial infarction. What tests
will the provider likely order and what medications should the nurse be prepared to
administer?
Discussion Guidelines: The patient will be attached to a cardiac monitor to evaluate his heart’s
