People are often surprised by how soon they can fly after a heart attack. Many expect months. For an uncomplicated heart attack treated quickly with a stent, published guidance commonly measures the wait in days.
That is the reassuring half. The other half is that it only applies if the heart is pumping well, nothing has gone wrong since, and no more treatment is planned. Most of the work is finding out which group you are in.
Why the heart minds the cabin
A commercial cabin sits at the equivalent of roughly 6,000 to 8,000 feet, the cabin altitude. There is less oxygen available at that pressure, and the oxygen level in the blood falls slightly even in healthy people.
A healthy heart copes easily. A heart that has just lost some muscle, or still has a narrowed artery that has not been treated, has less in reserve. Lower oxygen makes it work harder for the same output, and that can bring on chest pain or an irregular rhythm.
The flight is also not the only demand. An airport means queues, long walks, carrying bags and sometimes running for a gate. For a heart in the first weeks after an attack, that can be the harder part of the trip.
How long people commonly wait
Published UK guidance, from the Civil Aviation Authority and the British Cardiovascular Society, commonly sorts patients into three groups after a heart attack.
Low risk. Broadly, a patient under 65, with a first heart attack, whose blocked artery was opened successfully, whose heart is pumping well on a scan, with no complications and no further tests or treatment planned. Guidance commonly allows this group to fly after around three days.
Medium risk. A patient whose heart is pumping reasonably well, with no signs of heart failure and no ongoing chest pain or rhythm problems, but who does not meet every low-risk condition. Guidance commonly suggests waiting around ten days.
High risk. A patient whose heart is pumping poorly, who has signs of heart failure, or who is waiting for further treatment such as another stent or bypass surgery. Guidance asks this group to wait until their condition is stable, and the date is set by the cardiologist rather than a table.
These are starting points. A cardiologist who knows your angiogram and your scan can say which group you are in, and that conversation is worth having before anyone changes a ticket.
Stents, bypass surgery and angina
A planned stent. If a stent was put in as a planned procedure, with no heart attack, commonly applied guidance suggests a wait of around two days. If the stent was put in to treat a heart attack, the heart attack sets the timing.
Blood thinners after a stent. After a stent you will usually be on two antiplatelet medicines for some time. Do not stop them, and do not run out of them while travelling. Carry the full supply in hand luggage, with enough to cover delays.
Bypass surgery. Heart bypass surgery is open-chest surgery and can leave air in the chest. Commonly applied guidance suggests around ten days for an uncomplicated recovery, and longer if there were complications.
Angina. Stable angina that is well controlled is not usually a reason to stay on the ground. Carry your GTN spray in hand luggage, not in the hold. Angina that is new, getting worse, or coming on at rest is different: it needs assessing before any flight. If short walks bring on chest pain, book airport assistance so the distance to the gate does not become the test.
Whatever the group, many airlines ask for airline medical clearance after a recent heart attack or heart surgery. A letter from the treating cardiologist covering the diagnosis, the treatment, the scan result and a statement that you are stable is the quickest way through it.
If you are stuck abroad, or managing a case
A heart attack is one of the commonest reasons a traveller needs help to get home. Very often the hospital abroad has done exactly the right thing: an angiogram, a stent, a few days on the ward. The patient feels well, the family is keen, and the remaining question is how to travel.
For a low-risk patient, a normal seat after the commonly applied interval, with assistance at the airport, is often enough. For a patient who is more frail, or in the medium-risk group, a seat with a medical escort adds someone who can recognise a problem and act on it. A patient who is high risk, unstable or still waiting for treatment needs a different conversation, sometimes with an air ambulance in it, and sometimes with the answer that the treatment should be finished first.
The documents that decide it are the discharge summary, the angiogram report, the heart scan, and the list of medicines. Cardiac rehabilitation after a heart attack is part of the treatment, so a plan that lands the patient at home with follow-up arranged is better than one that just lands them. That is the principle set out in what good repatriation actually looks like.
If you are arranging this for a family member or managing it for an insurer, medical repatriation and patient transport explains how the move is planned around the heart rather than the flight.
