If a heart attack leads to heart failure. The resulting edema is due to blood backing up in the vessels, but do the valves function as normal?
Meaning do the ventricles and atriums get filled as normal and the blood doesn’t flow backwards. But they don’t get fully emptied, due to the heart’s diminished pumping/contraction strength, and as a result of their partial emptying, when they do get filled again, they eventually “overflow” and hence the blood backs up resulting in edema?
In: Other
so like the valves work normally kinda. but when the heart can’t pump well the blood doesn’t leave fast enough. it fills up and overflows like a bath tub. so yeah edema happens when that backup occurs. kinda wild how the heart can mess things up, right?
