Abstract. Over a 9-yr period, heart transplantation was performed in 200 patients at Sahlgrenska University Hospital. Of these 200 patients, 151 were followed for 1 to 9 yr with regard to renal function, hemodynamics, cyclosporin A concentrations, and complications. Patients with a preoperative serum creatinine >130 μmol/L received inotropic drugs to test for reversibility of renal dysfunction. The end point was graft failure. The average preoperative GFR of 66 ± 17 ml/min per 1.73 m2 declined to 52 ± 19, 44 ± 16, and 37 ± 17 at 1, 5, and 9 yr after heart transplantation, respectively. Altogether, the average GFR declined by 44%. There was no significant correlation between the preoperative GFR and postoperative renal function or survival. Recipient age was a predictor of renal function during the entire follow-up. Severe renal dysfunction (GFR <20 ml/min per 1.73 m2) developed in 20% of the patients, which was predicted by the recipient age at transplantation together with the GFR 1 yr after transplantation. A nomogram that shows the risk of developing severe renal dysfunction after heart transplantation is presented. Cyclosporin A concentrations and treatment with statins, calcium channel blockers, or angiotensin-converting enzyme inhibitors did not correlate with the evolution of renal function. Patients with a preoperative depressed renal function who improved on inotropic treatment seemed to have a poorer outcome compared with the other study patients.
