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 more
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 more
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
Would low cardiac output show up on an echo? I seem to have the symptoms but echo was fine. Cannot find ejection fraction listed, though.
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?
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 more
Echo after 5 weeks of female 58 yrs rescue angioplasty followed by cardiac arrest showed ejection fraction 39% with pap = 40. Any need to worried?
Is it normal to have an ejection fraction of 64% on echocardiogram and a ejection fraction of 57% on Cardiac MRI? With the same heart.
No worry!: The ejection fractions measured by echo and by MRI are just estimates. Both the results are close to each other and the difference is no cause for concern. Normal would be between 55 and 70% and your results are both normal and quite close to each other! Relatively speaking! Good! ...Read more
Does an ejection fraction of 48% and tachycardia increase my risk for a heart attack or cardiac arrest? My echo results scared me.
Increases for CHF: Need further studies. Consult your cardiologistGet a more detailed answer ›
What does it mean when you have a cardiac catheterization and the result says that the the ejection fraction was 70%. The left ventricular end-diastolic pressure was mildly elevated at 17 mmhg. There was no gradient or lval pullback and no mitral regurt
See below: The ejection fraction is the percentage of blood in the heart at rest which is ejected with the following heartbeat. The end-diastolic pressure is the filling pressure in the heart just prior to contraction. The aortic valve separates the left ventricle from the aorta. If the valve is functioning normally, there should be no gradient. ...Read more
61 yr old hypertensive male has total occlusion of right coronary andom. Stenting of om1 done. Ejection fraction is 45-50%. Is CABG indicated for rca?
Likely no: The damage that could have been done from the occluded rca has already happened, and the vessel can't get worse than totally occluded, so, provided that anginalsymptoms symptoms are controlled there is no need to do anything. Overtime, compensation typically occurs for an occluded vessel in the form of progressive collateral circulation. ...Read more
Heart catheterization report say : minimal coronary artey disease, 50% diagonal small branch. Ejection Fraction 55%. what does it mean?
Not worrisome: The report says it all: "minimal" coronary disease. Many otherwise healthy people have cholesterol build-up in their arteries that causes no problems. Having said that, it's a reminder that diet and exercise and avoidance of smoking are needed to keep these from turning into problems. The 55% ejection fraction is normal. It means the heart is pumping well. ...Read more
Congestive heart failure I was diagnosed with CHF and a 80 percent block of the right coronary artery my ejection fraction is up to 55-60 from 25-30 I still get tired and short of breath not getting answers from my doctor could that be from the block any
That: That is great news that your ejection fraction (ef) has improved that much, as that is directly correlated with your overall long term prognosis. You clearly are still symptomatic though. If you find that your shortness of breath continues, it is certainly possible that the stenosis in your right coronary artery is the culprit, although without knowing more information it is hard to say definitively. My best advice to you is to find a physician that will answer your questions and communicate with you so that you may understand your care. Heart disease is complex and involves the interplay of many factors, and an excellent relationship with your cardiologist can be the most important one. ...Read more
What treatment/comfort is available for end stage chf? Having trouble breathing; has to stand most of time to breathe. 13% ejection fraction from recent heart attack due to collapsed stent.. . History of coronary artery disease since 1990
Ur hida scan abnormal, wit a low ejection fraction and reproduction of symptoms with the cck injection. I prefer an answer from someone n nuclear rx.
Normal: That is normal.....Get a more detailed answer ›
It may be possible: To improve your EF, but you need to talk to your cardiologist about what is possible in your particular clinical situation. ...Read more
Theoretically, if the left ventrical was hypotrophied it would raise ejection fraction? Would a dialated lv lower ef? Not an issue, just curios.
Which is a concern?: Left Ventricular Hypertrophy would not RAISE an ejection fraction...but a dilated, thin Left ventricle could LOWER an EF. TWO different issues. WHIch is a concern for you? ...Read more
Reduced gb ejection: Gallbladder ef determined as percentage emptying of gall bladder on hida nuclear medicine study with administration of cck (cholecystokinin, hormone). In adults usually greater than 35% is normal. Low gbef can be related to gall bladder disease or dyskinesia. Usually compared to findings on ultrasound such as gall stones or wall thickening. Gbef affected by degree of fasting and pain medications. ...Read more
Usually gb disease: Decreased ejection fraction is less than 35%. May mean chronic gall bladder disease or biliary dyskinesia. If symptoms of biliary colic (gall bladder disease) may receive relief with gall bladder removal. Work up of gall bladder disease usually includes ultrasound study looking for gall stones. ...Read more
Is there any study that shows using Half & Half in a HIDA scan is as accurate as CCK? My ejection fraction was 31%
Here is the link for that study:
http://jnm. Snmjournals. Org/content/43/12/1603.full
It shows that there is wide variability in the ejection fraction measured when half and half, instead of CCK, is used in a HIDA scan. However, the study concludes that both methods are acceptable. Hope that helps! ...Read more
Depend on: The actual heart condition of the person. If the person have a heart condition causing low ef a cardiac rehabilitation program with close follow up by cardiologist will be the best. If the person is healthy, then stay healthy avoiding smoking, alcohol, healthy diet and with a program of aerobic and strength muscle exercise. Make exercise part of your daily routine. ...Read more
Information: There are multiple ways. Consult your cardiologist. ...Read more
Depends: It should stay right where it's at unless there's ongoing or intermittent heart damage (like amyloid disease or heart attacks respectively). 60% is "normal" and "abnormal" doesn't start until <55%. But bear in mind that ef is a fairly inaccurate measure (95% confidence window of +/- 12% by standard noncontrast echocardiography) so don't read to much in a few percent here and there. ...Read more
