High-output heart failure is a heart condition that occurs when the cardiac output is higher than normal because of increased peripheral demand. There is a circulatory overload which may lead to pulmonary edema secondary to an elevated diastolic pressure in the left ventricle .
Severe anemia leads to hyperdynamic circulation, which means high-output cardiac failure causes the blood to circulate rapidly. The excessive pumping of blood causes the left side of the heart to fail leading to pulmonary edema. The build up of fluid in the lungs increases the pressure in the lungs leading to vasoconstriction.
Symptoms usually include one or more of the following: orthopnea (difficulty breathing while lying flat), dyspnea (shortness of breath) on exertion, pitting edema (swelling), cough, frequent night-time urination, excessive weight gain during the last month of pregnancy (1-2+ kg/week; two to four or more pounds per week), palpitations (sensation of racing heart-rate, skipping beats, long pauses ...
In 2011, nonhypertensive heart failure was one of the 10 most expensive conditions seen during inpatient hospitalizations in the U.S., with aggregate inpatient hospital costs more than $10.5 billion. [166] Heart failure is associated with a high health expenditure, mostly because of the cost of hospitalizations; costs have been estimated to ...
Untreated profound anemia can cause high-output heart failure, with pallor, enlarged liver and/or spleen, generalized swelling, and respiratory distress. [citation needed] HDN can be the cause of hydrops fetalis, an often-severe form of prenatal heart failure that causes fetal edema. [5]
Pregnancy Test - pre-eclampsia in pregnancy can cause dangerously high blood pressure [3] Lactate - rising lactate in the blood indicates that areas of the body are not getting enough oxygen [ 11 ] Cultures - blood cultures and source-specific cultures (urine, sputum, etc.) should be collected when septic shock is suspected in order to identify ...

It is the normal response to healthy exercise or pregnancy, [6] which results in an increase in the heart's muscle mass and pumping ability. It is a response to 'volume-overload', either as a result of increased blood return to the heart during exercise, or a response to an actual increase in absolute blood volume as in pregnancy.
