The purpose of the heart is to pump blood to all the body parts to nourish it. Heart failure does not mean that the heart has stopped working, but it means that the heart us not able to pump effectively to meet the needs of the body. When there is a defect in the heart or if it gets weaker than normal the heart is not able to pump blood into the circulation. Our body depends on the pumping action of the heart for the delivery of oxygen an nutrients to body parts in order to function properly. There are many causes of congestive heart failure. Coronary artery disease is one of the common disease of arteries that supply oxygen and blood to the heart and this causes decreased in the blood flow to the heart muscles which caused lack of oxygen …show more content…

In this essay, the author

  • Explains the purpose of the heart is to pump blood to all the body parts to nourish it. heart failure does not mean that it has stopped working.
  • Explains that there are many causes of congestive heart failure, including coronary artery disease, myocardial infarction, and emboli.
  • Explains that congestive heart failure is caused by hypertension, which makes the heart harder to pump blood. heart muscle damage can be due to infections, alcohol abuse, and toxic effects of some drugs.
  • Explains the two categories of congestive heart failure: systolic and hypertension.
  • Explains that diastolic heart failure arises due to an abnormality in the cardiac function, rhythm, structure and conduction. ventricular dysfunction causes myocardial infarction, hypertension or both.
  • Explains the clinical manifestations of congestive heat failure due to inadequate perfusion and pulmonary vascular congestion.
  • Explains that diagnosis of congestive heart failure is determined by physical examination, patient history and several other tests. testing for b-type natriuretic peptide (bnp) can be helpful.

Ventricular dysfunction accounts for most of the cases which results from myocardial infarction, hypertension or both. The heart tries to make up for this decreased efficiency in a few ways. First the heart chambers will enlarge and stretch more and contract strongly so it can pump more blood. Due to this, the body will start to retain fluid and causes the heart to pump faster and this helps increase the heart’s output. Loss of the normal function of Left ventricles impairs the ventricular filling( preload). This causes left-atrial pressure and pulmonary venous pressure which further cases pulmonary congestion. In simple terms, when the left ventricles becomes incompetent and can not function and pump blood to the body and fluid backs up from the left ventricle to the left atrium and through pulmonary vein into the lungs. This causes edema in the lungs which causes pulmonary edema. This causes fluid in the alveoli which will cause the patient to have a cough and when the fluid mixes with the surfactant, this causes the classic sign of pink foamy sputum. If this progresses further, it can lead to right sided heart failure which furthermore causes back up of blood into the venous system and causes peripheral
