I am 25 healthy female without and heart disease in my family. I have had chest pain on and off for a year. I have had every blood test under the sun and I have had ECG electrocariograms and I have ...
That your heart is only working just over 1/3 of what it should best thing to help heart diet and exercise, obviously seek medical advice first!
By definition, the volume of blood within a ventricle immediately before a contraction is known as the end-diastolic volume. Similarly, the volume of blood left in a ventricle at the end of contraction is end-systolic volume. The difference between end-diastolic and end-systolic volumes is the stroke volume, the volume of blood ejected with each beat. Ejection fraction (Ef) is the fraction of the end-diastolic volume that is ejected with each beat; that is, it is stroke volume (SV) divided by end-diastolic volume (EDV):
Ejection fraction (Ef) = SV / EDV = (EDV - ESV) / EDV
In a healthy 70-kg (154-lb) man, the SV is approximately 70 ml and the left ventricular EDV is 120 ml, giving an ejection fraction of 70/120, or 58%. Right ventricular volumes being roughly equal to those of the left ventricle, the ejection fraction of the right ventricle is normally equal to that of the left ventricle within narrow limits.
Healthy individuals typically have ejection fractions greater than 0.55. However, normal values depend upon the modality being used to calculate the ejection fraction. Damage to the muscle of the heart (myocardium), such as that sustained during myocardial infarction or in cardiomyopathy, impairs the heart's ability to eject blood and therefore reduces ejection fraction. This reduction in the ejection fraction can manifest itself clinically as heart failure. The ejection fraction is one of the most important predictors of prognosis; those with significantly reduced ejection fractions typically have a poorer prognoses.
Ejection fraction-70 to 50%-good- 5 year survivalafter surgery for three-vessel disease-90%.
EF-Moderate-50 to 30%
EF-Poor-30 to 15%-5 year survival- only 45%.
Not enough information.
If your EJECTION FRACTION is 35% you are in need of a major value replacement.
If that is your STROKE VOLUME, it is 35 ml per beat and the normal is around 50-70 ml per beat. That means you need to start doing some medically supervised exercises.
If that is your OXYGEN SATURATION, then you are dead.
If that is your CO2 SATURATION, that is way low for venous blood and you may be having to hyperventilate to get enough oxygen. IE: Your lungs are darn near shot.
Pretty much anything I can think of that comes out as 35% is not good. You might ask your doctor for more details as to what he means.
