What is the maximum permissible left ventricular ejection fraction (LVEF) to certify a driver with congestive heart failure?

• A. 20%
• B. 35%
• C. 40%
• D. 50%

Answer: (C)

The maximum permissible left ventricular ejection fraction (LVEF) for certifying a driver with congestive heart failure is set at 40%. LVEF is a critical measurement that indicates how well the heart is pumping blood and provides insight into the health of the heart muscle. An LVEF at or above this threshold means that the driver is likely to have sufficient cardiac function to safely operate a commercial vehicle. A value of 40% is significant because individuals with congestive heart failure may face limitations due to reduced heart function, which could impact their ability to perform the demanding tasks associated with driving. By setting this threshold, the regulatory framework seeks to balance road safety with the opportunity for individuals with heart conditions to maintain their livelihood and independence. A lower LVEF would typically indicate more severe heart dysfunction, increasing the risk of adverse events while driving. Thus, maintaining this 40% benchmark ensures that only those with a healthier cardiac output are considered fit for certification.
