Cardiac Risk Stratification for CMV Certification

Cardiac conditions are evaluated under § 391.41(b)(4)-(7). Medical examiners consult FMCSA Medical Review Board guidelines for specific conditions.

Conditions that may disqualify (with timing)

• Acute myocardial infarction: typically 3 months minimum recovery before recertification
• Coronary artery bypass graft (CABG): typically 3 months minimum
• Percutaneous coronary intervention (PCI / stent): typically 1 week minimum
• Implantable cardioverter-defibrillator (ICD): generally disqualifying for primary prevention; may be eligible for secondary prevention
• Heart failure: depends on ejection fraction; under 40% typically disqualifying without specialist clearance
• Severe arrhythmias: AFib, sustained ventricular tachycardia — depends on management
• Hypertension uncontrolled: above 180/110 typically disqualifying; controlled to under 140/90 acceptable

Documentation required for certification post-event

• Cardiologist clearance letter (treating physician)
• Recent ejection fraction (echocardiogram or angiogram)
• Stress test results
• Medication list with stability documentation
• Symptom-free period demonstration

Continued monitoring

• Annual exam minimum
• Some conditions trigger 6-month exam cycle
• Cardiologist re-evaluation annually for stable conditions; every 6 months for active management

Common driver concerns

• "I had a stent — can I keep driving?" → after waiting period + cardiologist clearance + medical exam, generally yes
• "I'm on blood thinners — does that disqualify?" → blood thinners alone do NOT disqualify; the underlying condition matters
• "I have an ICD — am I done?" → for primary prevention, likely yes; for secondary prevention with stability + clearance, possibly continuation

Compass tracking

• Driver's cardiac history flagged if disclosed
• Next medical exam (typically 12 months, sometimes 6)
• Cardiologist visit dates if applicable
• Medication compliance reminders for cardiac drugs

CFR citations

• 49 CFR § 391.41(b)(4)-(7)
• FMCSA Medical Review Board Cardiac Guidelines
