Normal Stroke Volume

I AM 34YRS; 160cms 60kgs HEIGHT WEIGHT;. Symptoms: chest pain with intermittent pain radiating down the left arm alone, or tingling. NO other health problems. I WAS A Cardiac MRI RESULTS TODAY.MRI VOLUNTEER revealed a normal cardiac structure and LA results above.

Stroke volume is the amount of blood pumped by the left side of your heart during each lesson. Ejection fraction and the fraction of blood pumped out of your ventricle during each lesson.
I am not an expert, but could you have been dehydrated during your MRI? And increase or decrease blood volume, corresponds to an increase or decrease in stroke volume and ejection fraction.There are other tests for a MUGA scan where they inject dye and measurement, and a echocardiography.

The stroke volume reflects the amount of blood pumped per stroke or beat. The stroke volume must be the same. If you're referring to the ejection fraction is the ratio of stroke volume to end diastolic volume (the amount of blood the heart is filled immediately before the onset of contraction). It represents the fraction of the amount of blood filling the heart that is ejected per beat by beat. Normally, this represents approximately 55% more or less and is a measure of the strength or weakness with which your heart contracts. If both SV and EF are low, it suggests that your heart is proportionately weakened in its function of pumping. Possible causes of this could include cardiac damage due to a heart attack before, myocarditis, hypertension, valvular disease and pericardial problems. Without the identification of structural MRI abnormalities there are no clues here as to the cause. If the values are minor, perhaps they should be confirmed by another imaging technique such as echo or Mugga. Talk to your doc.
