Congestive Heart Failure: The Many Differences
Congestive heart failure is a very common disease. While many other forms of heart disease have become less common, heart failure has been increasing. Congestive heart failure has become the most common diagnosis in the hospital for patients over 65 years of age. Diastolic heart failure accounts for up to 40% of patients with congestive heart failure and is associated with a better prognosis as compared to patient with systolic dysfunction (Arora, Krummerman, Vijayaraman, Rosengarten, Suryadevara, Lejemtel, and Ferrick, 2005). Congestive heart failure occurs when the flow of blood from the heart (cardiac output) decreases, or fluid backs-up behind the falling ventricle. The comparison of the different types of congestive heart failure and what happens in the heart are unilateral, directional, time dependent, phasic, and output vs. demand heart failure.

The heart is basically two pumps in one. The right side of the heart and the left side of the heart can fail independently of the other. Unilateral heart failure is this type of heart failure. Left sided heart failure is when the left ventricle cannot pump out enough blood and it gets backed-up in the lungs. A buildup of fluid in the lungs, called pulmonary edema, can cause shortness of breath and often leading to right sided heart failure. Right sided heart failure is when the right ventricle cannot pump out enough blood, causing fluid to back up in the vein and capillaries. The backup of fluid leaks out and builds up in the tissue, a condition called systemic edema. The edema is commonly noticed in the lower half of the body.

Directional heart failure has two types as well. Backwards heart failure is when the ventricle is not pumping out all the blood that comes through it. The increase in the ventricle filling pressure causes...
