Your left ventricular ejection fraction (LVEF) of 40.8% falls into what's considered the "borderline or midrange" category. This may indicate some heart damage, possibly from a previous heart attack, but it's close to the normal range which starts at 50%.
A low ejection fraction generally indicates that the heart's pumping action is weaker than normal. This could suggest heart failure with reduced ejection fraction (HFrEF) or cardiomyopathy, which means your heart muscle may be enlarged, thick, or stiff. The good news is that cardiac rehabilitation can help improve ejection fraction. One MyHeartDiseaseTeam member shared that their ejection fraction improved from 31% to 40% through cardiac rehab. Consider discussing cardiac rehabilitation with your healthcare provider as part of your treatment plan.
It's important to have regular follow-ups with your cardiologist to monitor both your left and right ventricular function and adjust your treatment plan as needed.
