Clinical Vignette
Read the clinical vignette. Discuss the patient's general approach, including laboratory
testing, inpatient management, and rationale discharge prescription, by answering the
given questions.
A 69-year-old man with a past medical history (PMH) of ischemic cardiomyopathy (EF
25%), CAD, HTN presents with a two-week history of dyspnea.
▪ Previously able to walk 3 km, currently cannot walk more than 3 m before
developing dyspnea on exertion (DOE). Paroxysmal nocturnal dyspnea
(PND) three times per night and four pillow orthopnea. Increasing lower
extremity edema.
▪ Review of Systems (ROS): loss of energy, loss of appetite, weight gain.
▪ Past medical history (PMH): ischemic cardiomyopathy (EF 25%, based on
echocardiogram 6 months prior), CAD (s/p MI with PCI in 2012), HTN.
▪ Home medications: ASA 81mg daily, Lisinopril 5mg daily, Lasix 40 mg daily.
▪ Allergies: no known drug allergies (NKDA).
▪ Review of Systems (ROS): denies Cerebral palsy (CP), denies dizziness, denies
palpitations.
▪ VS: Temp 36.5, HR 90, BP 108/72, RR 20, SpaO2 91% on RA
▪ Pertinent physical exam:
o General: appears uncomfortable, able to speak short sentences
o HEENT: Jugular venous distension at 10 cm
o CVS: left ventricular enlargement.
o Chest: A decrease tactile fremitus indicates chronic obstructive pulmonary
disease.
o Abdomen: distended, (+) mild fluid wave, (+) hepatojugular reflux,
o Extremities: 2+ pitting edema up to knees bilaterally, cool to touch, 2+ DP
and PT pulses
o Current presentation consistent with acute decompensated heart failure
(ADHF)
▪ What labs and toxicology screening should be ordered to help evaluate further?
▪ How often should his electrolytes be monitored?
▪ At this point, what imaging should be obtained to further assist with management?

▪ Should an echocardiogram be repeated?
▪ How should inpatient management begin (Drugs chart/ inpatient prescription)?
▪ Suggest which groups of drugs improve the mortality and morbidity in this patient
management.
▪ Clarify how the patient’s volume status should be improved.
▪ What could be done next if the patient did not respond to the treatment given for
patient’s volume status?
▪ Is Digoxin should be included in this patient management (justify).
▪ Should the patient’s management begin with a beta blocker at this time?
▪ Which beta blocker (if any) should be chosen?
▪ Which risk about blood pressure?
✓ The patient has been having an appropriate diuresis
✓ Clinically, patient reports improvement in shortness of breath and now able to
walk without DOE
✓ Pulmonary embolism (PE): resolution of rales, peripheral edema
▪ Rationale the patient’s discharge prescription?
▪ Clear the rational and importance of the medicines in the discharge prescription.
