    Abstract:
    AIM: To study structural-functional changes in left ventricular (LV) myocardium in recipients of renal allograft (RA) after different postoperative period and to specify factors promoting persistence, progression or regression of LV hypertrophy (LVH). MATERIAL AND METHODS: The study included 240 recipients of primary RA (38% females and 62% males, age 16-69 years, mean age 42 +/- 11 years). A prospective study covered 143 patients. RESULTS: LVH was diagnosed in 52% patients. LVH incidence after renal transplantation (RT) had a wave-like dynamics: during 9 months after RT LVH presents in more than 50% patients; after 9-24 months after the operation it fell to 30% and after 3-7 years after the operation it affected at least 2/3 patients. After RT LVH risk factors were age, duration of chronic renal failure (CRF) and pretransplantation dialysis, reduced mass of the operating nephrons, arterial hypertension, anemia, functioning of arterio-venous fistula (AVF) and chronic inflammation syndrome. LVH was also associated with factors specific for RT: RA rejection crises, infections complicating massive immunosuppressive therapy. LVH is also associated with proteinuria which may indicate RA damage and can be considered as a marker of generalized endothelial dysfunction. 2-year and longer follow-up after RT confirmed complete LVH regression in 1/3 of the recipients. LVH regression was observed in normal RA function, normal blood pressure, the absence of proteinuria, hypoalbuminemia, anemia, AVF, infectious complications. CONCLUSION: LVH after RT is multifactorial and can completely regress in a favourable posttransplantation course.
