NR507 Advanced Pathophysiology
Week 3
Discussion
A 64-year-old woman presents to the primary care office with
shortness of breath, leg swelling, and fatigue. She has a history of type 2
diabetes and hypertension. She reports that recently she had been able to go
for daily walks with her friends, but in the past month, the walks have become
more difficult due to shortness of breath and fatigue. She also sometimes
awakens in the middle of the night due to shortness of breath and has to prop
herself up on three pillows. On physical examination, she is tachycardic (110
beats per minute) and has a blood pressure of 106/74 mm Hg. Fine crackles are
noted on inspiration in bilateral bases. The cardiac exam reveals the presence
of a third and fourth heart sound and jugular venous distension. 2+ pitting
edema is noted in the knees bilaterally. An ECG shows sinus rhythm at 110 bpm
with Q waves in the anterior leads. An echocardiogram shows decreased wall
motion of the anterior wall of the heart and an estimated ejection fraction of
25%. She is diagnosed with systolic heart failure, secondary to a silent MI.
Discuss the pathophysiological mechanisms that can lead to
heart failure.
Differentiate between systolic and diastolic heart
dysfunction
Discuss the causes of the patient’s shortness of breath,
awakening in the middle of the night and the need to prop herself up on three
pillows. Include pathophysiological mechanisms that causes each of these signs
and symptoms.
Include two points of teaching for this patient
Support your response with at least one current evidence
based resource.
Students must post a minimum of three times in each graded
discussion (see participation guidelines on the discussion rubric).
