What should I think about before travelling abroad with heart failure? 

Living with heart failure does not mean you have to stop exploring the world. However, travelling requires a higher level of preparation to ensure your heart remains stable. Changes in altitude, extreme temperatures, and the physical stress of long flights can all put an extra burden on a failing heart. By planning ahead, securing the right insurance, and understanding how to manage your symptoms in a new environment, you can reduce these risks. Your goal is to enjoy your trip with the peace of mind that comes from having a solid medical plan in place.

Choosing Your Destination 

Not all holiday spots are equal when it comes to heart health. You should consider how the environment will affect your breathing and energy levels. 

• Altitude: High altitudes (above 2,000 metres) have lower oxygen levels. This can make breathlessness significantly worse. If you have heart failure, it is usually best to avoid mountain resorts. 

• Temperature: Extreme heat makes your heart beat faster to cool you down, while extreme cold narrows your blood vessels and raises your blood pressure. Aim for moderate, temperate climates. 

• Terrain: Consider the local geography. A city with many steep hills or many stairs (like parts of Lisbon or some Greek islands) might be more taxing than a flat coastal resort. 

Air Travel and Being ‘Fit to Fly’ 

Flying is safe for most people with stable heart failure, but there are specific safety factors to consider. 

1. Oxygen Levels 

Aircraft cabins are pressurized, but the oxygen level is still slightly lower than at sea level. If you can walk 100 metres on flat ground or climb one flight of stairs without severe distress, you are likely fit to fly. If you use home oxygen, you must coordinate with the airline weeks in advance. 

2. Deep Vein Thrombosis (DVT) 

Heart failure patients have a higher risk of blood clots. On long flights: 

• Wear compression stockings (check the size with your pharmacist). 

• Perform seated leg exercises every hour. 

• Walk up and down the aisle when the seatbelt sign is off. 

Travel Insurance and Health Cards 

Standard travel insurance often excludes ‘pre-existing conditions,’ which can leave you with massive bills if you need hospital care abroad. 

• Medical Disclosure: You must be 100% honest when applying for insurance. If you don’t declare heart failure, your policy will be void. 

• Specialist Providers: You may need a specialist insurer that focuses on chronic health conditions. 

• GHIC/EHIC: If travelling to Europe, ensure your Global Health Insurance Card (GHIC) is valid. It provides access to state healthcare at the same cost as a local, but it is not a replacement for travel insurance. 

Medication Management 

Your medications are your lifeline, and you must protect them during your journey. 

• Pack Extra: Always take at least one week’s worth of extra medication in case of travel delays. 

• Carry-On Only: Never put your life-saving tablets in your checked luggage. If the bag is lost, you are at risk. 

• The ‘Letter of Necessity’: Ask your GP for a letter listing your medications and confirming they are for your heart. This helps with customs and if you need to see a doctor abroad. 

• Time Zones: If you are travelling across many time zones, talk to your nurse about how to space out your doses safely. 

Airport Security and Devices 

If you have a pacemaker or an ICD, security scanners require caution. 

• Handheld Wands: Security staff should not hold a metal detector wand directly over your device. 

• Body Scanners: Most modern airport scanners are safe, but you should always inform the staff and show your device identification card. 

• The ‘Pat Down’: You have the right to request a manual pat-down search instead of going through a walk-through metal detector if you are concerned. 

Conclusion 

Travelling with heart failure is entirely possible with a proactive approach to planning. By selecting a heart-friendly destination, ensuring you are fit for the physical demands of your journey, and carrying the correct documentation and insurance, you can travel safely. Always have a ‘Plan B’ and know where the nearest hospital is at your destination. Your heart failure should be a consideration in your travel plans, but it shouldn’t be a barrier to enjoying the world. 

Emergency Guidance 

If you experience severe breathlessness, new chest pain, or a shock from your ICD while abroad, seek medical help immediately. Do not wait until you return to the UK. Use the local emergency number (such as 112 in Europe or 911 in the USA) and ensure you have your medical letter and insurance details ready for the attending doctors.
