Abstract
The prevalence of congestive heart failure is on the increase both in the United States and all over the world, and it is the leading cause of hospitalization in the elderly population. Congestive heart failure is a progressive disease generally seen in the elderly, which if not properly managed, can lead to repeated hospital admissions or death. Heart failure means that the heart muscle is weakened. A weakened heart muscle may not be strong enough to pump an adequate amount of blood out of its chambers. To compensate for its diminished pumping capacity, the heart may enlarge. Commonly, the heart's pumping inefficiency causes a buildup of blood in the lungs, a condition called pulmonary congestion.
Prevalence
Congestive heart failure continues to grow in prevalence due to the ageing population and the survival rates of myocardial infarctions (Fundukian, 2011). Congestive heart failure means that the heart is still pumping blood, but at a slower rate than normal, so the pressure in the heart starts to increase as a result. This slower heart rate causes the heart to be unable to pump enough blood to provide the rest of the body with the amount of nutrients and oxygen that it needs. As the pressure increases in the heart, the chambers stretch to hold more blood, or they become stiff and thickened. This compensation mechanism works, but eventually the myocardium will weaken and the heart will decrease in its efficiency to pump blood. This results in a reduction of blood supply to the kidneys, which then begin to lose their ability to excrete salt and water. This lessened function of the kidney causes the body to retain more fluid. The fluid build-up then leads to edema or congestion of tissues (Fundukian, 2011).
Incidence
Congestive heart failure is a serious condition with significant morbidity and mortality. In the United States, African Americans significantly have a
