What is the maximum certification period of a 44-year-old male CMV driver with a history of angina pectoris and who provides a cardiologist report dated 4 months before indicating that he is asymptomatic, tolerant to medication, and achieved 110 bpm as a maximum heart rate (HRmax) on ETT?
Explanation
Answer: D - Not to be certified
This is the correct answer because his medical report is older than 3 months and his ETT is abnormal, as he achieved less than 65% intensity. For a person his age, a 65% intensity on ETT corresponds to a maximum heart rate of 114 bpm (for males it is calculated as follows: HRmax = 220 - age x 0.65). According to FMCSA guidelines, an individual with a history of angina pectoris is disqualified if they show rest angina or changes in angina within the past 3 months, abnormal ETT, ischemic changes on rest ECG, and intolerance to cardiovascular medication.
