Can You Define Cardiac Output And Ejection Fraction
I have congestive heart failure with a 30% ejection fraction, hypertrophic cardiomyopathy , and left bundle branch block is it safe for me to fly?
Depends: It depends on your overall health. Do you have an icd, are you on daily oxygen, daily medications, can you sit for exended lengths of time, how long is the flight? Commercial airlines have cabin pressures set to about 7000ft. So if you can tolerate that altitude (denver is about 5600ft), air travel may be ok. Discuss with your doctor. Tsa will need to know if you have an icd. ...Read moreSee 1 more doctor answer
Resting HR 120-160 found in notes I also have Left ventricular ejection fraction 52% been passing out a lot should I be worried/is this the cause?
Unfortunately yes: You could be having a dangerous heart rhythm, leading to the passing out. The ejection fraction of 52% is still within the normal range; however, you are tachycardic at baseline, and the fast heart rate may overestimate your true ejection fraction as well as lead to heart damage. If you pass out again, I recommend calling 911, otherwise, see cardiologist ASAP. ...Read moreSee 2 more doctor answers
I hope so!: It's part of what cardiologists do for a living. Ejection fraction is the percentage change in ventricular volume in one beat. 55% or better is normal but >75% suggests a hyperdynamic state which may be physiologic or pathologic. Cardiac output is the volume of blood (in liters per minute) that the heart pumps. Co is the product of stroke volume (blood in ccs per beat) x the heart rate (bpm). ...Read more
If left ejection fraction is maintained in diastolic heart failure, why is the cardiac output decreased?
Think stiffness: In diastolic dysfunction, the heart muscle tends to be stiff, so that it doesn't "relax" well and fill with blood. So even if the heart can pump blood forward OK, if it doesn't fill up appropriately, then it won't function optimally ... ...Read more
35-40% cardiac ejection fraction during pregnancy. 11weeks. How serious is this? What shld I do? Do I need to restrict activities, etc?
Important Info: It is important to know if there is history of a depressed EF. One might think that this could be peripartum cardiomyopathy but this usually presents in the final weeks of pregnancy or the week after that. This does not mean that could not happen in the first trimester but it would be unusual. It would be important to rule out any type of congenital disorder in the echocardiogram. ...Read more
Can ejection fraction of 35% after heart attack... In general be improved by cardiac excersize, or meds only. Is ef based only on amt of damage?
Exercise,time: In general, there will be some improvement in ef over the 6-8 week following a heart attack. This is due to some shrinkage of the scar, and compensation by the undamaged part of the heart. Recovery will be improved with regular aerobic exercise, such as in a cardiac rehab program. Medications will definitely also help the process, and are a recommended part of the treatment. ...Read moreSee 1 more doctor answer
