Patient survival after renal transplantation: II. The impact of smoking

Renal transplant recipients have significantly higher mortality than individuals without kidney disease and the excess mortality is mainly due to cardiovascular causes. In this study, we sought to determine the impact of smoking, a major cardiovascular risk factor, on patient and renal graft survival. The study population included all adult recipients of first cadaveric kidney transplants done in our institution from 1984 to 1991. By selection, all patients were alive and had a functioning graft for at least 1 yr after transplantation. Smoking history was gathered prior to transplantation. The follow‐up period was 84.3±41 months and during this time 28% of the patients died and 21% lost their graft. By univariate and multivariate analysis, patient survival, censored at the time of graft loss, correlated with these pre‐transplant variables: age (p
