Cardiovascular disease (CVD) is frequent in kidney transplant (Tx). This study investigated CVD prediction in kidney Tx by information available pre-Tx or within six months post-Tx. Study cohort consisted of 629 patients with Tx in 2005-10 and with adult age at Tx. Endpoint was the incidence up to 2015 of CVD (coronary heart disease, cerebrovascular disease, peripheral artery disease). Graft failure, non-CVD death with functioning graft, and loss to follow-up were considered competing events. CVD prediction was investigated for thirty-four variables using competing-risks regression. Follow-up range was 0.28-10.00 years (mean±SD= 7.30±3.10). First incident event was CVD in 103 patients and competing events in 146 patients. In multi-variable model for pre-Tx variables only, CVD predictors were male sex (hazard ratio= 1.68, 95%CI= 1.06/2.66), diabetic nephropathy (6.63, 1.81/24.35), pre-Tx dialysis for ≥5 years (1.52, 1.02/2.27), pre-Tx CVD (4.87, 2.84/8.35), age at Tx ≥45 years (2.98, 1.83/4.87). In model for pre-Tx and post-Tx variables together, the sole post-Tx CVD predictor was estimated glomerular filtration rate <60 mL/min at the 6-month visit (1.75, 1.11/2.77). Diabetic nephropathy, pre-Tx dialysis, pre-Tx CVD, and age at Tx predicted 91.2% of incident CVD. Early available information effectively predicted CVD in kidney Tx independent of competing events.

Abstract
Cardiovascular disease (CVD) is frequent in kidney transplant (Tx). This study investigated CVD prediction in kidney Tx by information available pre-Tx or within six months post-Tx. Study cohort consisted of 629 patients with Tx in 2005-10 and with adult age at Tx. Endpoint was the incidence up to 2015 of CVD (coronary heart disease, cerebrovascular disease, peripheral artery disease). Graft failure, non-CVD death with functioning graft, and loss to follow-up were considered competing events. CVD prediction was investigated for thirty-four variables using competing-risks regression. Follow-up range was 0.28-10.00 years (mean±SD= 7.30±3.10). First incident event was CVD in 103 patients and competing events in 146 patients. In multi-variable model for pre-Tx variables only, CVD predictors were male sex (hazard ratio= 1.68, 95%CI= 1.06/2.66), diabetic nephropathy (6.63, 1.81/24.35), pre-Tx dialysis for ≥5 years (1.52, 1.02/2.27), pre-Tx CVD (4.87, 2.84/8.35), age at Tx ≥45 years (2.98, 1.83/4.87). In model for pre-Tx and post-Tx variables together, the sole post-Tx CVD predictor was estimated glomerular filtration rate <60 mL/min at the 6-month visit (1.75, 1.11/2.77). Diabetic nephropathy, pre-Tx dialysis, pre-Tx CVD, and age at Tx predicted 91.2% of incident CVD. Early available information effectively predicted CVD in kidney Tx independent of competing events.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
