People whose spouse has suffered from cancer may wish to prepare to fund coronary heart disease treatments through expatriate medical insurance policies, following the publication of a study that revealed they have an elevated risk of suffering from this cardiac condition.
The investigation, which was published in the journal Circulation and led by Jianguang Ji and his colleagues at Malmo's Centre for Primary Healthcare Research, said the cause of this correlation is likely to be the negative stress these individuals are exposed to.
Members of the public whose partner has had cancer were found to be between 13 and 29 per cent more likely to suffer from coronary heart disease or stroke than other people.
Previous studies have shown relatives of men and women with chronic illnesses such as cancer have a higher chance of suffering from depression and mental health problems.
Furthermore, these conditions are known to impact blood pressure, the nervous system and inflammation levels, which can cause cardiac problems and stroke.
Investigators considered the possibility that the correlation between a person developing cancer and the wellbeing of their spouse could be due to similar lifestyles between the two people, but realised the likelihood of a person suffering from cardiovascular disease was only between three and five per cent higher than average in the period before their significant other was diagnosed with cancer.
"Our study shows that preventive efforts aimed at reducing psychological stress and negative risk factors are important for people whose life partner has got cancer," Jianguang Ji said.
"Previous studies have shown that preventive work can considerably reduce stress and anxiety in close relatives of patients," he added.
Canada's Queen's University political studies professor Colin Farelly recently argued medical researchers should look into the science of wellbeing, asserting this could result in notable medical breakthroughs and might deal with the problem of biological aging.
