Cardiovascular Risk after Kidney Transplantation: Causes and Current Approaches to a Relevant Burden.

BACKGROUND

Cardiovascular disease is a frequent complication after kidney transplantation and represents the leading cause of mortality in this population.

MATERIAL AND METHODS

We searched for the relevant articles in the National Institutes of Health library of medicine, transplant, cardiologic and nephrological journals.

RESULTS

The pathogenesis of cardiovascular disease in kidney transplant is multifactorial. Apart from non-modifiable risk factors, such as age, gender, genetic predisposition and ethnicity, several traditional and non-traditional modifiable risk factors contribute to its development. Traditional factors, such as diabetes, hypertension and dyslipidemia, may be present before and may worsen after transplantation. Immunosuppressants and impaired graft function may strongly influence the exacerbation of these comorbidities. However, in the last years, several studies showed that many other cardiovascular risk factors may be involved in kidney transplantation, including hyperuricemia, inflammation, low klotho and elevated Fibroblast Growth Factor 23 levels, deficient levels of vitamin D, vascular calcifications, anemia and poor physical activity and quality of life.

CONCLUSIONS

The timely and effective treatment of time-honored and recently discovered modifiable risk factors represent the basis of the prevention of cardiovascular complications in kidney transplantation. Reduction of cardiovascular risk can improve the life expectancy, the quality of life and the allograft function and survival.
