Link Between Post-bypass Survival and Civil Status Discovered

Civil status, education, and income are factors shown to be clearly associated with duration of survival after a bypass operation.

Risk of dying prematurely after a bypass surgery is found to be higher if a person lives alone or income and education are is low, stated new study.

This is the first time such a strong association between social factors and life expectancy after the surgery has been visible," says Susanne Nielsen, a surgical nurse and researcher at Sahlgrenska Academy, University of Gothenburg.

Coronary Artery Bypass Graft (CABG) - Triple Bypass Surgery
Triple bypass surgery, an open heart surgery involves grafting blood vessels from either the chest or leg onto 3 blocked blood vessels.

‘A postoperative patient aged 60 with a spouse or cohabiting partner, high educational attainment, and high income has a median life expectancy five years longer than a corresponding person with no live-in partner, a low education level, and low income.’

The study, published in the Journal of the American Heart Association and funded by the Swedish Heart-Lung Foundation, is based on data on 112,000 women and men who underwent coronary artery bypass grafting (CABG) in Sweden from 1992 to 2015.

Data were taken from the Swedish Heart Surgery Registry, which is part of the SWEDEHEART (Swedish Web system for Enhancement and Development of Evidencebased Care in Heart Disease Evaluated According to Recommended Therapies) quality registry, and from the Swedish Cause of Death Register, the Swedish National Inpatient Register (IPR), and the Longitudinal Integration Database for Health Insurance and Labor Market Studies register (LISA).

Coronary Artery Bypass Grafting (CABG) | Coronary Artery Bypass Surgery
Coronary artery bypass grafting (CABG) or heart bypass surgery is an open heart surgery to relieve the blockages of the arteries of the heart. Coronary artery bypass surgery lasts up to 3 to 6 hours.

The research shows that various factors are associated, both jointly and individually, with differences in post-CABG life expectancy, irrespective of sex and age.

Susanne Nielsen, who belongs to Professor Anders Jeppsson's research group, stresses the importance of everyone, after CABG, taking the medication prescribed.

Animation on Coronary Artery Bypass Surgery (CABG)
Coronary Artery Bypass Surgery (CABG) is performed to restore the blood supply to areas of heart that have been reduced or has no blood supply due to blockage in the artery.

Care professionals also need to ask the patients about their social circumstances and whether they need any extra support, Nielsen thinks. Undergoing CABG is, for many, a big event and this can make it more difficult for them to take in all the information and advice they are given. "As a patient, you get lots of information and it's hardly surprising that it's hard to take it all in. So it's very important for patients not to hesitate about asking questions if they don't understand the advice they're given by the care and medical staff they come into contact with," Nielsen states.
