- Surviving the first month after surgery means you should live well for a decade
- Patients can also expect to have the same quality of life as the average person
- The effectiveness of previously healthy blood vessels may wane over time
- Researchers say patient’s health should be checked, particularly 10 years later

Heart bypass surgery patients often live a healthy life after their operation – but it may only last for 10 years, new research reveals.
Modern surgical procedures mean survival rates are better than ever, however, the mortality rate eight to 10 years later increases by up to 80 per cent compared to the general population.
The researchers believe this may due to the return of any progressive condition that the patient suffered from pre-surgery.
Lead researcher Kasper Adelborg from Aarhus University in Denmark, said: ‘The rate of survival has improved over the last three decades, so the probability of continuing your life following bypass surgery is close to being the same as in the general population.
‘Clinicians in contact with patients should assess their prognosis individually – and there are special reasons to do this after the initial eight to 10 years, as we now know that “something” happens.’

COULD A BLOOD TEST PREDICT YOUR SURVIVAL CHANCES AFTER SURGERY?
A simple blood test may predict a patient’s chances of survival after surgery, a new study suggests.
High levels of a specific protein in the bloodstream may indicate that someone is suffering from inflammation in their body, scientists claim.
This, known as the body’s response to injury, is heavily linked to heart attacks, kidney failure and even strokes.
Monitoring levels of troponin, the protein responsible, may help doctors know which patients need extra care after an operation, according to the researchers from The James Cook University Hospital in Middlesborough.
How the study was carried out
Researchers from Aarhus University analysed data from a 30-year study of adults including 51,000 who had undergone a heart bypass operation and 500,000 who had not.
Heart bypass surgery involves rerouting the blood supply around a damaged section of the artery by attaching healthy blood vessels from elsewhere in the body.
Key findings
Results revealed that those who survive the first month after surgery are likely to be able to carry on as normal and have the same quality of life as those who have not had the operation.
Lead researcher Kasper Adelborg, said: ‘The rate of survival has improved over the last three decades, so the probability of continuing your life following bypass surgery is close to being the same as in the general population.’
Yet, death rates eight to 10 years later showed bypass survivors have a 60 to 80 per cent higher mortality rate.
The researchers believe this may be due to the patient’s original progressive condition, that caused their arteries to become diseased, returning.
Alternatively, the previously healthy blood vessels attached to the diseased artery may lose their effectiveness over time.
Mr Adelborg said: ‘Clinicians in contact with patients should assess their prognosis individually – and there are special reasons to do this after the initial eight to 10 years, as we now know that “something” happens.’
The findings were published in the journal Circulation: Cardiovascular Quality and Outcomes.
