Kidney donors 'have no higher risk of heart disease'

  • Comment

The risk of heart disease is not higher in people who have donated a kidney than in those who have not, according to new research.

The study, which involved 2.028 living kidney donors in Ontario and 20,280 people who had not donated a kidney, found that the risk of a first major cardiovascular event or death was even slightly lower in donors than in non-donors, at 2.8 events per 1,000 person years and 4.1 events respectively.

The researchers from Canada, Australia and the USA also said the general risk of a major heart-related event was roughly the same for kidney donors (1.7 events per 1,000 person years) and non-donors (two events per 1,000 person years).

The risk was also found to be the same for young and old donors, which could be due to the fact that only healthy people are allowed to donate a kidney.

The study, which was published online in the British Medical Journal, was conducted because a reduced kidney function in non-donors is usually strongly connected to the risk of heart disease, and it was unclear whether this also applies to donors.
