Great question! Left ventricular shortening fraction (LVSF) is a measure of how well your heart's main pumping chamber is contracting. It's related to, but different from, ejection fraction (EF).
A normal shortening fraction is generally considered to be between 28% and 44%. So a reading of 30–35% actually falls within the Show Full Answer
Great question! Left ventricular shortening fraction (LVSF) is a measure of how well your heart's main pumping chamber is contracting. It's related to, but different from, ejection fraction (EF).
A normal shortening fraction is generally considered to be between 28% and 44%. So a reading of 30–35% actually falls within the normal range — that's reassuring news!
Here's a quick breakdown:
- Normal: 28%–44%
- Mildly reduced: 20%–27%
- Significantly reduced: Below 20%
It's worth noting that shortening fraction and ejection fraction are two different ways of measuring heart function. A normal ejection fraction is typically between 50% and 70%. Since your shortening fraction of 30–35% appears to be within the normal range, that's a positive sign. However, every person's situation is unique, and it's always best to discuss these numbers directly with your cardiologist, who can interpret them in the full context of your heart health and symptoms.
