Background: Heart failure is a complex clinical syndrome in which the heart cannot pump enough blood to meet the body's requirements. Heart failure is a complex clinical syndrome that results from a functional or structural heart disorder impairing ventricular filling or ejection of blood to the systemic circulation this produces a reduction in cardiac output, which then becomes inadequate to meet the peripheral demands of the body. Heart failure can severely decrease the functional capacity of a patient and increase mortality risk. It is imperative to diagnose and effectively treat the disease to prevent recurrent hospitalizations, improve quality of life, and enhance patient outcomes. Coronary artery disease and diabetes mellitus have become the predominant predisposing factors for heart failure. Other structural causes of congestive heart failure (CHF) include hypertension, valvular heart disease, uncontrolled arrhythmia, myocarditis, and congenital heart disease.
