Heart failure:
HF is a complex clinical syndrome that results from any
structural or functional impairment of ventricular
filling or ejection of blood.
Systolic HF (( systolic dysfunction)) :
* Impaired ejection
* Decreased contractility
Signs and symptoms :
- Low EF (<45%)
- Cardiomegaly
- S3
- Normal wall thickness
- Hypokinesis
- Symptoms primarily those of reduced cardiac output
Chief Complaint
“I’ve been more short of breath lately. I can’t seem to walk
as far as I used to, and either my feet are growing or my
shoes are shrinking!”
History Of Present Illness (HPI)
Rosemary Quincy is a 68 yo African-American female who
presents to her family medicine physician for
evaluation of her shortness of breath and
increased swelling in her lower extremities.
She reports that her shortness of breath has been gradually
increasing over the past 4 days.
She has noticed that her shortness of breath is particularly
worse when she is lying in bed at night, and she has to
prop her head up with three pillows in order to sleep.
She also reports exertional dyspnea that is usual for her,
but especially worse over the past couple of days.

Assessment
Admit to hospital for acute exacerbation of heart failure.
Clinical Pearl
The presence of pitting edema is associated with a substantial increase in
body weight; it typically takes a weight gain of 10 lb to result in the
development of pitting edema.

1.b. What signs, symptoms, and other information
indicate the presence and type of heart failure in
this patient ?
signs
Shortness of breath over the
past 4 days .
Increased swelling in the
lower extremities.
Exertional dyspnea.

HR 65 (irreg.irreg)
Displaced PMI
S3 sound present
Cardiomegaly
3+ pitting pedal edema
Interstitial edema
Early alveolar edema
Small right pleural effusion
Skin color pale & diaphoretic.
1.c.
What is the classification and staging of
chronic heart failure for this patient
stage 4 according to ( NYHA Functional Classification).
She has acute exacerbation of heart failure with left systolic
dysfunction.
1.d.
Could any of this patient’s problems have
been caused by drug therapy?
Pioglitazone is a 1ST generation sulfonurea which
exacerbate heart failure and cause pedal edema
with weight gain.
And intake of carvedilol with B2 agonist
worsening of COPD by antagonism.
There is also a glimepiride which increase CV
mortality.
2.a.
What are the goals for the pharmacologic
management of heart failure in this patient?
• Control the disease and prolonging survival by
improving quality of life .
• Relief symptoms of dyspnea & orthopnea .
• Decrease edema & swelling.
• Fluid restriction & Minimizing disability.
• Manage the acute exacerbation of her HF.
3.a.
What diuretic therapy should be recommended
for this patient initially for acute treatment of
her heart failure exacerbation?
• Use the same diuretic which is furosemide but
in IV/IM: 10 to 20 mg once over 1 to 2 minutes.
A repeat dose similar to the initial dose may be
given within 2 hours if there is an inadequate
response. Following the repeat dose, if there is
still an inadequate response the last IV dose
may be raised by 20 to 40 mg until there is an
effective diuresis.
•
Single doses NOT exceeding 200 mg.
3.b.
How should this patient’s pharmacotherapy be
adjusted for chronic management of her heart
failure?
• Change B blocker to metoprolol succinate to prevent
interaction with b2 agonist which is salmeterol.
• Titrate furosemide oral dose to 80 mg( max 600)
• Warfarin dosage should adjusted according to results
of International Normalized Ratio (INR) or prothrombin
time (PT).
• Increase the dose of glimepiride after stopping
pioglitazone .
Continue on Warfarin and Aspirin.
For HTN management associated with heart faliure :
Continue on valsartan& furosemide
For atrial fibrillation:
It managed by warfarin & carvedilol that replaced with metoprolol
succinate.
For Dyslipidemia:
Continue on atorvastatin.
For COPD management :
Continue on albuterol ,tiotropium,
Continue on fluticasone /salmetrol
For hypokalemia :
Continue on pottasium chloride supplements with monitoring
3.c.
What non pharmacologic therapy should be
recommended for this patient with respect to her
heart failure?
•
Dietary modifications such as low sodium & cholesterol
diet.
• Risk factor reduction including stopping alcohol
consumption and supervised regular physical activity.
• O2 therapy to be >90% if the pt has hypoxia.
• bed rest during exacerbation .
• Fluid restriction.
4. What drugs, doses, schedules, and duration are
best suited for the management of this patient?
Drug
Initial Daily
Dose(s)
Maximum
Dose(s)
Duration of action
Metoprolol
succinate

Furosemide

or twice
600 mg
6 to 8 h
valsartan
40 mg twice daily
80 to 160 mg once
daily
5. What clinical and laboratory parameters are
needed to evaluate the therapy for achievement of
the desired therapeutic outcome and to detect and
prevent adverse events?
• Initially monitor patient for rapid relief of
symptoms related to the chief complaint of
orthopnea, dyspnea , oxygenation & fatique.
• Monitor for adequate perfusion of vital signs:
• asses mental status , Cr Cl , stable HR btw 50-100
HR/min,BP.
• Monitor kidney& liver function.
• monitor blood glucose
• Fluid intake – body weight (daily)-
• Metoprolol succinate:
• BP, HR baseline and after Carvedilol 3.125 mg twice 25
mg twice each dose titration, ECG
• Furosemide :
• monitor electrolyte ,hyperuricemia , nephrotoxicity &
autotoxicity.
• Valsartan :
• Monitor potassium and serum creatinine
6. What information should be provided to the
patient about the medications used to treat her
heart failure?
• Furosemide taking on empty stomach
• Grapefruit juice can increase the blood levels of
Atorvastatin. This can increase the risk of side
effects such as liver damage
• Take Metoprolol at the same time each day, preferably with
or immediately following meals
• Avoid taking potassium rich food.
• Glimepiride should be administered with breakfast or the
first main meal.
