<unk>  is a complex syndrome characterized by inadequate blood ejection or impaired ventricular filling, leading to the inability of the heart to pump blood to meet the metabolic demands of the body.<unk>  is a clinical syndrome for which the diagnosis relies mainly on symptoms and physical examination findings.  The main symptoms and signs of<unk>  are dyspnea, volume overload (leading to pulmonary edema and/or peripheral edema), fatigue, and exercise intolerance.  Acute decompensated<unk>  (ADHF) is a life-threatening condition that can occur in the setting of a new onset<unk>  or worsening of an existing chronic<unk> .  Symptoms of ADHF may include dyspnea secondary to pulmonary edema, peripheral edema, hypotension, and impaired end organ perfusion that can manifest by worsening renal function, altered mental status, and cold clammy extremities.  The mainstays of treatment of ADHF are 1) oxygen therapy to improve hypoxia, 2) diuresis to reduce both preload and intravascular volume, and 3) vasodilators to reduce afterload.  The goals of treatment for chronic<unk>  are to relieve symptoms, decrease hospitalization rate, and decrease morbidity and mortality. Treatment of<unk>  includes identification and management of precipitating factors, lifestyle changes, pharmacological therapy, and devices.
