what is left sided heart failure?

Answer 1

LHF is the exhaustion (failure) of the left ventricle to pump blood to aorta and to supply all the body.
so the cardiac output is decreased,the blood accumlates before the left ventricle(as the ventricle fails to pump it forwards to the body) , accumlates in lung and right ventricle (which may ends in RHF) and finally viens,so the body suffers anoxia and exhaustion due to decreased blood supply.
it can be caused by :
1-hypertension
2-severe anemia
3-heart attack
4-congenital anomaly in the heart
5-coarctation of aorta
6-atherosclerosis
it has variety of symptoms:
1-dyspnea
2-ankle edema leads to genralized edema(anasarca)
3-hepatosplenomegaly
4-exhaustion on exertion
5-pallor
6-anginal attacks
7-headache
8-attacks of cardiac asthma (pulmonary edema).
it is treated by medications which lower blood pressure and improve the cardiac pumping efficiency as:
1-digtalis
2-arteriodilators

Answer 3

It is when the left side of the heart is not functioning properly. This causes the left atrium and ventricle to fail and heart muscle dies(heart attack) Heart failure can occur in any part of the heart.The left ventricle pumps the blood out to the rest of the body and when it fails there is inadequate tissue perfussion and you go into shock.( Not enough blood goes to the body tissues to keep them alive)

Answer 4

This is also called congestive heart failure, the left side of the heart fails to pump adequate blood, and blood backs up in the pulmonary circuit. therefore pulmonary blood vessels become congested.

Answer 5

this is when the chambers on the left side of your heart fail. most likely the ventricles, which are important in pumping blood to your organs brain muscles etc... depending on the severity you can get fluid held up in your lungs and a drop in blood pressure

Answer 6

It means you are in for a slow painful ordeal.
