[|AI|]  Hello. Thank you for your question and welcome to Chat Doctor. I carefully read your query. The "something" that was told to you, is probably the ejection fraction of the left ventricle of the heart. It is a component that describes heart function and, if it is 0.6 or 60%, then it means that this heart fills, pumps and contracts properly (normal ranges being 0.55-0.7, or 55-70%). Stress itself produces rapid heart rate and high blood pressure, almost always. This is attributed to high levels of a Chat Doctor.
