Most people with heart disease can travel safely, including by air, with a bit of planning specific to their condition and any device they carry.
General Air Travel Considerations
Cabin pressurization during flight is equivalent to moderate altitude (roughly 6,000–8,000 feet), which lowers blood oxygen slightly. This is generally well tolerated, but worth discussing in advance if you use home oxygen, have pulmonary hypertension, or have advanced heart failure. Long flights also carry a modest blood clot (DVT) risk for everyone, higher with reduced mobility or certain heart conditions — move and stretch periodically, consider compression stockings, and discuss blood thinner timing with your team if applicable.
Guidance by Condition or Device
- Stable coronary disease or heart failure: generally fine to fly; carry your medications in your carry-on, not checked luggage.
- Recent heart attack or procedure: most centers recommend waiting a defined period after the event or procedure before flying — ask your care team for your specific timeline rather than assuming.
- Pacemaker or ICD: safe to fly. Airport security may detect the device — carry your device ID card, and you can request alternative screening if you prefer to avoid lingering near security wands.
- LVAD: air travel is possible for many patients but requires specific advance planning with your VAD team — airline notification, equipment and battery logistics, a letter for security, and backup power covering the full flight duration plus layovers.
- After transplant: generally safe once stable. Discuss destination-specific infection risks (certain regions or foods) given immunosuppression, and plan travel vaccinations well in advance (see Vaccination Guidance).
- Pulmonary hypertension: oxygen needs during flight should be discussed specifically with your PH team before booking.
Practical Packing & Planning Tips
- Carry a medication list and enough medication for the full trip, plus a buffer, in your carry-on
- Bring a brief written summary of your condition or device, and emergency contacts
- Know how to access care at your destination before you need to
- Consider travel insurance that covers pre-existing conditions for major trips
- Device patients should carry manufacturer ID cards and any required documentation
- Research the nearest hospital or emergency facility at your destination in advance, particularly for remote or international travel
International Travel Considerations
- Time zone changes can affect medication timing — ask your care team how to handle a multi-timezone trip, particularly for medications taken at specific times relative to meals or sleep
- Research destination-specific health risks, including which vaccines or medications (like malaria prophylaxis) might interact with your heart medications
- Carry medication names using their generic (not just brand) names, since brand names vary by country, and consider a printed prescription list translated if traveling somewhere your language isn't spoken
- Confirm your health insurance's coverage abroad, and consider supplemental travel medical insurance for extended or remote trips
Common Questions
Do I need a doctor's letter to fly?
Often recommended for device patients or those with a recent cardiac event — ask your team.
Can I go through airport body scanners?
Generally yes, but device patients should inform security and can request alternative screening.
What about travel to high-altitude destinations, not just flying?
A different consideration than cabin pressure — worth a specific conversation for advanced heart failure or pulmonary hypertension patients before booking.
Should I carry a copy of my medical records when I travel?
For anyone with a significant cardiac history, a brief written summary (diagnosis, medications, device information, and your cardiologist's contact information) can be genuinely valuable if you need care away from home and don't have access to your usual records.
Do I need to plan around time zone changes for my medication schedule?
For most medications, adjusting gradually over the first day or two at your destination works fine — but for anticoagulants and a few other timing-sensitive medications, ask your care team for specific guidance before a trip with a significant time change.
