What is the minimum left ventricular ejection fraction (LVEF) required for a driver to meet health criteria?

The minimum left ventricular ejection fraction (LVEF) required for a driver to meet health criteria is 40%. This threshold is established because an LVEF below this level may indicate significant compromise in the heart's ability to pump blood effectively, which can lead to symptoms of heart failure or a higher risk of cardiovascular events.

A driver with an LVEF of 40% or higher is generally considered to have an adequate level of cardiac function, allowing for safe operation of a commercial vehicle. This criterion helps ensure that drivers are not at an increased risk of sudden incapacitation while driving, which is crucial for road safety.

In contrast, LVEF values below this threshold, such as those indicated by the other choices, would suggest a greater risk, potentially disqualifying individuals from safely driving commercial vehicles.
