  2. 1 of 2HFSA 2010 Practice GuidelineDefinition of Heart Failure • A syndrome caused by cardiac dysfunction • Generally resulting from myocardial muscle dysfunction or loss • Characterized by left ventricular dilatation or hypertrophy • Leading to neurohormonal and circulatory abnormalities and characteristic symptoms: • Fluid retention • Shortness of breath • Fatigue, especially on exertion • Left untreated, usually progressive at the levels of cardiac function and clinical symptoms. • Severity of clinical symptoms may vary substantially during course of the disease process and may not correlate with changes in underlying cardiac function.

  3. 2 of 2HFSA 2010 Practice GuidelineDefinition of Heart Failure • Although HF is progressive and often fatal, patients can be stabilized and myocardial dysfunction and remodeling may improve, either spontaneously or as a consequence of therapy. • In physiological terms, HF is a syndrome characterized by: • Elevated cardiac filling pressure OR • Inadequate peripheral oxygen delivery, at rest or during stress, caused by cardiac dysfunction.

  4. HFSA 2010 Practice GuidelineHF with Reduced LVEF • Sometimes called: "HF with a Dilated Left Ventricle" • A clinical syndrome characterized by signs and symptoms of HF and reduced LVEF • Most commonly associated with LV chamber dilation

  5. HFSA 2010 Practice GuidelineHF with Preserved LVEF • Sometimes called: "HF with a Non-Dilated LV" • A clinical syndrome characterized by signs and symptoms of HF with preserved LVEF. • Most commonly associated with a non-dilated LV chamber. • May be the result of valvular disease or other causes.

  6. HFSA 2010 Practice GuidelineMyocardial Remodeling • Pathologic myocardial hypertrophy or dilation in response to increased myocardial stress. • These changes are generally accompanied by pathologic changes in the cardiac interstitium. • Myocardial remodeling is generally a progressive disorder.
