	What Is Heart Failure?
		Heart failure is a condition in which the heart can’t pump enough blood throughout the body.
		Heart failure does not mean that your heart has stopped or is about to stop working.
		Heart failure develops over time as the pumping action of the heart grows weaker.

	eMedicine - Heart Failure : Article by Michael E Zevitz, MD
		Heart failure always causes circulatory failure, but the converse is not necessarily the case because various noncardiac conditions (eg, hypovolemic shock, septic shock) can produce circulatory failure in the presence of normal, modestly impaired, or even supranormal cardiac function.
		In diastolic heart failure, altered relaxation of the ventricle (due to delayed calcium uptake by the myocyte sarcoplasmic reticulum and delayed calcium efflux from the myocyte) occurs in response to an increase in ventricular afterload (pressure overload).
		Left-sided heart catheterization and coronary angiography should be undertaken when the etiology of heart failure cannot be determined by clinical or noninvasive imaging methods or when the etiology is likely to be due to acute myocardial ischemia or myocardial infarction.

		Heart failure is a syndrome (a collection of signs and symptoms with various causes).
		The severity of heart failure can be classified symptomatically by the use of a scheme such as the New York Heart Association (NYHA) functional classification, which groups patients according to the amount of effort needed to produce heart failure symptoms.
		Patients with heart failure should be considered for an imaging study (echocardiogram, radionuclide scan) if one has not been performed, unless the study is precluded by an advance directive or by the patient's or advocate's informed decision to decline the study.

	Congestive Heart Failure — Complete medical information regarding congestive heart failure on MedicineNet.com
		Congestive heart failure (CHF) is a condition in which the heart's function as a pump is inadequate to meet the body's needs.
		The strength (forward pumping function) of the heart may be impaired (so called systolic dysfunction) due to illnesses that cause heart muscle weakness or the ability of the heart to relax and fill may be impaired.
		Additionally, in some cases, although the pumping action of the heart may be intact, other factors due to abnormal demands by the body's tissues may make it difficult for the heart to supply an adequate blood flow (called high output heart failure).
