Heart failure is when the heart is too weak to pump blood efficiently, and cannot provide proper cardiac output that the body needs to maintain the body’s metabolic needs. Also, heart failure is when the heart muscle has become damaged and cannot contract and pump blood up and through the valves and out through both sides of the heart or the heart muscle has become too stiff. This process mainly relates to the heart muscles of the ventricle chambers. The ventricles are the main problem within heart failure, they are either too stiff or not contracting properly. The heart ventricles cannot pump hard enough during systole, which is called systolic heart failure. Diastolic heart failure is when not enough blood fills into the ventricles during

This dysfunction is due to damage to the myocardium, the middle layer of the heart muscle. Damage to the myocardium prevents the heart from contracting as forcefully and pumping blood as efficiently as it should. This is the squeezing phase of the blood up through the heart. The stroke volume divided by the end diastolic volume, and multiplied by 100 gives you the ejection fraction, which should be fifty to seventy percent when normal, forty to fifty percent would be considered borderline, and anything that is forty percent or less would indicate systolic heart failure because the heart would only be squeezing out a little blood during each …show more content…
The pulmonary vessels will then get congested with blood. The backup increases the blood pressure in the pulmonary vessels and causes pulmonary hypertension that leads to pulmonary edema. Pulmonary edema is the leakage of fluid into airspaces of the lungs. This occurs because the body tries to lessen the severity of the pulmonary hypertension by leaking excess fluid in the vessels into the empty spaces in the lungs. The empty spaces in the lungs now filling with fluid are normally used for the oxygenation of the blood. The lungs that are now full of fluid cause dyspnea, a shortness of breath since oxygen exchange is impaired because of fluid in the
