My cardiac index is 2.3. Is it low?

Hello,

Welcome to icliniq.com.

The cardiac index is a bit on a lower side, but two of the ejection fractions are normal. Normal is more than 55 percent. If two of the three readings are normal, then we should consider your function to be normal. And since heart function is normal, cardiac index assumes less importance. So overall, I do not think there is anything to worry about it. Also, you must have undergone echo, which is a direct indicator of ejection fraction. So, if the echo also shows a normal ejection fraction, then it confirms normal heart function. MRI (magnetic resonance imaging) is more important for other findings like fibrosis, fatty changes, or late gadolinium enhancement. So if any of these are present, then need further evaluation. I hope this helps.

Stroke volume is supranormal and cardiac output is normal. So, it is excellent. Such supranormal stroke volume may be seen in bradycardia, which might be included during an MRI scan for better image quality. So, nothing to worry about it.
