ACUTE HEART FAILURE IS A CHALENGING DISORDER
1. Highly prevalent especially among the elderly
2. High rate of hospital readmission, early recurrent
events, and mortality
3. Progressive disorder
4. Heterogeneity in etiology and LV function
5. Characteristic, management, and outcomes have
been poorly defined

DEFINITION OF HEART FAILURE
The heart fails to pump blood
commensurate with the requirement of the
metabolizing tissue
orThe heart can pump blood commensurate
with the requirement of the metabolizing
tissue only from an elevated filling
pressure

Definition of Chronic Heart Failure
• A syndrome in which patients have symptoms of HF (dyspnea and fatigue) with evidence of cardiac dysfunction and a clinical response to treatment directed to HF alone (The ESC guidelines) 1
• A clinical syndrome as a result of cardiac dysfunction that impairs the ability of the ventricle to fill and eject blood, producing symptomatic manifestation of HF (The ACC/AHA guidelines) 2

Definition of Acute Heart Failure
Acute heart failure is characterized by a
rapid or gradual onset of sign and
symptoms of heart failure, resulting in
unplanned hospitalization or office or
emergency room visits. Nieminen MS, Harjola V-P. Am J Cardiol 2005;96(suppl):5G-10G

The New York Heart Association functional classification
Class ClassificationI Patients with cardiac disease but without limitation of
physical activity. Ordinary physical activity does not cause undue fatique, palpitation, dyspnea, or anginal pain
II Patients with cardiac disease resulting in slight limitation of physical activity. They are comfortable at rest. Ordinary physical activity results in fatique, palpitation, dyspnea, or anginal pain
III Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary physical activity results in fatique, palpitation, dyspnea, or anginal pain
IV Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of cardiac insufficiency or anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased

KILLIP CLASSIFICATION
STAGE I : No clinical signs
STAGE II : Heart failure. Diagnostic criteria: rales S3 gallop and pulmonary veins hypertension. Pulmonary congestion with wet rales in the lower half of the lung fields
STAGE III : Severe heart failure. Frank pulmonary edema with rales over the lung filds
STAGE IV : Cardiogenic shock. Signs: hypotension (SBP 90 mm Hg), and evidence of peripheral vasoconstriction such as oliguria, cyanosis and diaphoresis

• Improve symptoms, especially congestion and low-output symptoms
• Optimize volume status• Identify etiology • Identify precipitating factors• Optimize chronic oral therapy• Minimize side effects• Identify patients who might benefit from
revascularization• Educate patients concerning medications and self
assessment of HF• Consider and, where possible, initiate a disease
management program

Rapid improvement of symptoms is
a desire goal, but should not
become the only goal in managing
AHF.
Many treatment modalities shown
to improve symptoms were shown
to increase mortality.

Intravenous vasodilators (intravenous
nitroglycerin or nitroprusside) and
diuretics are recommended for rapid
symptom relief in patients with acute
pulmonary edema or severe
hypertension.

Intravenous inotropes (milrinone or
dobu-tamine) are not recommended
unless left heart filling pressures are
known to be elevated based on direct
measurement or clear clinical signs.
