I. Description: Congestive Heart Failure is more of a syndrome than a disease. Heart failure may be classified according to the side of the heart affected, (left- or right-sided failure), or by the cardiac cycle involved, (systolic or diastolic dysfunction). (Schilling-McCann p. 176). The word "failure" refers to the heart's inability to pump enough blood to meet the body's metabolic needs. (Schilling-McCann p. 176). When the heart fails to deliver adequate blood supply edema may develop. (Cadwallader p. 1141). Where edema occurs depends on what side of the heart is failing.
Left-sided heart failure results from the inability of the left ventricle to function properly. Blood fails to get out to other parts of the body as quickly as it returns from the lungs. When blood doesn't get back to the heart, it backs up in the lungs blood vessels. Blood is then forced into the intracellular space in the lungs causing......
