Don't plug your raw aortic root measurement into an online calculator and diagnose yourself. Your cardiologist knows which reference set their lab uses. Always compare apples to apples. z score aortic root
In cardiology, this measurement is typically taken at the —the widest part of the aortic root. Why Z-Scores Matter Don't plug your raw aortic root measurement into
If you see a Z-score under 2.0, breathe easy—that’s statistically normal. If you see a Z-score between 2.0 and 3.0, you need surveillance (annual echoes). If you see a Z-score above 3.0, you need a specialized cardiologist to discuss management. In cardiology, this measurement is typically taken at
