Abstract
Deficit železa je častou komorbiditou u pacientov s chronickým srdcovým zlyhávaním a asociuje so zhoršenou prognózou chorého. Dotýka sa to kvality života chorých a častejších rehospitalizácií. Metabolizmus železa je zložitý a máme dnes aj novšie informácie, hlavne u chorých so srdcovým zlyhávaním. Tieto článok pripomína. Rozoberá aj absolútny a funkčný deficit železa. U srdcového zlyhávania práve deficit železa ovplyvňuje prognózu chorého, a nie tak prítomnosť anémie. Prevalencia anémie u srdcového zlyhávania je asi 30–35 %, vyššia je u osôb s častejšími akútnymi dekompenzáciami ochorenia. Liečba deficitu železa je potrebná a priaznivo zlepšuje prognózu. Najviac skúseností z klinických štúdií je s i.v. podávaním železa (štúdie FERRIC HF, FAIR HF, CONFIRM HF), a menej informácií máme o perorálnom príjme železa. Zatiaľ neboli publikovane veľké a dlhotrvajúce štúdie s podávaním železa, ktoré by analyzovali mortalitu ochorenia. Kľúčové slová: liečebný prístup u deficitu železa – metabolizmus železa u srdcového zlyhávania – prevalencia deficitu železa – srdcové zlyhávanie
Iron deficiency is a frequent comorbidity in a patient with chronic heart failure, and it associates with a worse prognosis of that patient. Mainly worse quality of life and more rehospitalizations are in these iron deficient patients. Iron metabolism is rather complex and there is some new information concerning this complexity in heart failure. We distinquish an absolute and a functional iron deficiency in heart failure. It is this deficit which is important and not as much is anemia important here. Prevalence of anaemia in heart failure is about 30–50 %, higher it is in patients suffering more frequently heart failure decompensations. Treatment of iron deficiency is important and it improves prognosis of these patients. Most experiences there are with i.v. iron treatment (FERRIC HF, FAIR HF and CONFIRM HF studies), less so with per oral treatment. There are no clinical trials which analysed mortality influences. Key words: heart failure – iron metabolism in heart failure – prevalence of iron deficit – treatment of iron deficiency in heart failure
