Cardiovascular disease remains one of the leading causes of FAA medical certificate denial and loss of medical. However, modern imaging and testing has made it possible to identify and manage cardiac risk while maintaining certification. Here is what pilots need to know about cardiovascular fitness evaluations in 2025.
Risk Stratification Changes
The FAA now accepts multiple modalities for cardiac risk assessment:
- Coronary Artery Calcium (CAC) Scoring - Non-invasive CT measurement of coronary calcium burden
- CT Coronary Angiography (CCTA) - Detailed visualization of coronary arteries
- Exercise Stress Testing - Functional assessment of cardiac capacity
- Stress Echocardiography - Combining exercise with cardiac ultrasound
- Nuclear Perfusion Imaging - Assessment of myocardial blood flow
Understanding CAC Scores
CAC scoring is increasingly used for asymptomatic pilots with cardiovascular risk factors:
| CAC Score | Interpretation | FAA Implications |
|---|---|---|
| 0 | No identifiable plaque | Excellent prognosis |
| 1-100 | Mild plaque | May require stress testing |
| 101-400 | Moderate plaque | Likely requires CCTA or stress imaging |
| >400 | Extensive plaque | Requires comprehensive evaluation |
CT Angiography for FAA Submissions
When CCTA is ordered, the FAA will evaluate:
- Presence and severity of stenosis (blockages)
- Plaque characteristics (calcified vs. non-calcified)
- Left main and proximal LAD involvement
- Evidence of prior interventions
Exercise Stress Test Standards
The FAA requires specific parameters for stress testing:
- Achieve 100% of age-predicted maximum heart rate (or 85% for pharmacologic stress)
- Minimum 9 METs for Class 1 certification
- No significant ST-segment depression
- No exercise-induced arrhythmias
- Appropriate blood pressure response
Post-Intervention Surveillance
Pilots with stents or bypass surgery require ongoing monitoring:
- Annual stress testing or imaging
- Lipid panel and metabolic markers
- Cardiology follow-up letters
- Documentation of medication compliance
Lifestyle Optimization
Beyond testing, the FAA and your cardiologist expect:
- Optimal lipid management (LDL <70 for high-risk)
- Blood pressure control
- Diabetes management if applicable
- Smoking cessation
- Regular exercise program
