Congestive heart failure (CHF) is a condition in which the heart fails to work adequately as a pump that can deliver oxygen rich blood to the body.
 The heart is made up of four chambers: two atria and two ventricles. The ventricles make up the lower chambers of the heart. They pump blood during the contraction of the muscles. This event is called systole. After each ventricular contraction (systole) the ventricle muscles take some time to relax during which blood from the upper chambers (atria) fills them. This is the diastole. A number of conditions cause diminished pumping ability of the ventricles. Heart attacks and infections (myocarditis) weaken the ventricular muscles leading to systolic dysfunction. Congestive heart failure can be caused by:  Diseases in which the heart muscle weakensDiseases in which the heart muscles stiffensConditions where oxygen demand by the body tissue is beyond the capacity of the heart (It is the heart that has to deliver adequate oxygen-rich blood)Conditions like hemochromatosis (iron overload) or amyloidosis cause stiffening of heart muscles. The ventricles'' capacity to relax is impaired and this is termed diastolic dysfunction. Long standing high blood pressure leads to a hypertrophied (i.e. a thickened) heart. In some patients the pumping action remains normal but the body requirements are much higher than what the heart can deliver. Conditions like anaemia or hyperthyroidism are often responsible for this. In some individuals one or more of these factors can co-exist and may present as a congestive heart failure. Let us focus on the congestive heart failure that is due to heart muscle weakness, i.e. systolic dysfunction. |

Posted on: 12/07/2010 Congestive heart failure can affect many organs. For example: The weakened heart muscle may not be able to deliver enough blood to the kidneys, which in turn begin to lose their normal ability to excrete salt and water. This can cause decreased kidney function in the body to retain more fluid. The lungs can become clogged with fluid and the ability of the person to take down. The fluid can also accumulate in the liver, which hinders their ability to rid the body of toxins and produce essential proteins. The intestines can become less efficient in absorbing nutrients and drugs. The fluid can also accumulate in the extremities, causing swelling of the ankles and feet.
