We aimed to investigate whether low post-transplantation-period hemoglobin levels are predictive of cardiovascular morbidity in terms of left ventricular (LV) hypertrophy and vascular stiffness and to determine the contributing factors of post-transplantation anemia in kidney transplant (KT) recipients. Methods. One hundred fifty (mean age, 38.9 +/- 10.8 y; 113 male) KT recipients with functioning grafts were enrolled in the study. All subjects underwent clinical and laboratory evaluations (24-hour urinary protein loss, complete blood count) and transthoracic echocardiography to assess LV systolic function. Arterial stiffness was measured by means of carotid-femoral pulse-wave velocity (PWV). Mean hemoglobin levels were analyzed at the 1st, 6th, 12th, and 24th months after transplantation. Patients were divided into 2 groups according to presence of anemia: patients with anemia (group 1; n = 120) and normal (group 2; n = 30). Results. PWV values (6.8 +/- 1.9 m/s vs 6.4 +/- 1.1 m/s in groups 1 and 2, respectively; P = .002) and LV mass index (LVMI; 252.1 +/- 93.7 g/m(2) vs 161.2 +/- 38.5 g/m(2) groups 1 and 2, respectively; P = .001) were significantly higher in group 1. Estimated glomerular filtration rate and (64 +/- 28.5 m/min vs 77.8 +/- 30 m/min in groups 1 and 2, respectively; P = .001) LV systolic function (57.2 +/- 5.8% vs 77.8 +/- 30% in groups 1 and 2, respectively; P < .005) were significantly lower in group 1. In regression analysis, LV systolic function and LVMI were predictors of post-transplantation hemoglobin levels. Conclusions. Post-transplantation anemia contributes to cardiovascular morbidity by deteriorating LV function and increasing PWV and is therefore associated with poor prognosis for graft survival. Early correction of post-transplantation anemia, especially with the use of erythropoietin, may be beneficial for both graft and recipient survivals.enginfo:eu-repo/semantics/closedAccessALL-CAUSE MORTALITYPATIENTIMPACTERYTHROPOIETINSURVIVALEVENTSRISKarticle474117811810003561840000742-s2.0-849303894941873-2623
