Abstract
Kontext: SrdeÄnĂ selhĂĄnĂ (heart failure, HF) se zachovanou ejekÄnĂ frakcĂ (EF) pĹedstavuje v poslednĂ dobÄ zĂĄvaĹžnĂ˝ zdravotnĂ problĂŠm. Je prokĂĄzĂĄno, Ĺže je vĂ˝znamnou pĹĂÄinou kardiovaskulĂĄrnĂ morbidity a mortality. PĹi srdeÄnĂm selhĂĄnĂ se snĂĹženou EF Äasto dochĂĄzĂ k dysfunkci pravĂŠ komory jako postiĹženĂ spojenĂŠmu s poruchou funkÄnĂ kapacity a nepĹĂznivou prognĂłzou. CĂl: CĂlem tĂŠto prĂĄce bylo hodnotit systolickou a diastolickou funkci pravĂŠ komory u pacientĹŻ se srdeÄnĂm selhĂĄnĂm a zachovanou ejekÄnĂ frakcĂ levĂŠ komory (LVEF). Metody: Do studie bylo zaĹazeno 50 pacientĹŻ se srdeÄnĂm selhĂĄnĂm se zachovanou ejekÄnĂ frakcĂ (heart fail- ure with preserved ejection fraction, HFpEF), "diastolickĂ˝m srdeÄnĂm selhĂĄnĂm" (LVEF ≥ 50 %) a 50 zdravĂ˝ch jedincĹŻ srovnatelnĂŠho pohlavĂ a vÄku. U vĹĄech ĂşÄastnĂkĹŻ studie se zaznamenĂĄval krevnĂ tlak a bylo provedeno vyĹĄetĹenĂ krve i ĂşplnĂŠ echokardiografickĂŠ vyĹĄetĹenĂ pravĂŠ komory (right ventricle, RV) a klasickĂŠ 2D echokardiografickĂŠ vyĹĄetĹenĂ levĂŠ komory (left ventricle, LV). VĂ˝sledky: PĹi pouĹžitĂ kritĂŠriĂ frakÄnĂ zmÄna plochy pravĂŠ komory (right ventricular fractional area change, RV FAC), maximĂĄlnĂ vychĂ˝lenĂ trikuspidĂĄlnĂho prstence v systole (tricuspid annular plane systolic excursion, TAPSE), vrcholovĂĄ systolickĂĄ rychlost (St) trikuspidĂĄlnĂho prstence (peak systolic tricuspid annular tissue velocity, Sʹ) a dopplerovskĂ˝ index vĂ˝konnosti myokardu (tissue Doppler myocardial performance index, TD MPI) byla nalezena prevalence systolickĂŠ dysfunkce pravĂŠ komory ve výťi 30, resp. 34, 32 a 36 %. PĹi hodnocenĂ pulsnĂ a tkĂĄĹovou dopplerovskou echokardiografiĂ s kritĂŠrii trikuspidĂĄlnĂho pomÄru E/A (T E/A), trikuspidĂĄlnĂho decelaraÄnĂho Äasu (tricuspid deceleration time, TDT) a trikuspidĂĄlnĂho pomÄru E/E` (T E/Eʹ) Äinila prevalence diastolickĂŠ dysfunkce pravĂŠ komory 64, resp. 32 a 48 %. ZĂĄvÄr: SystolickĂĄ a diastolickĂĄ dysfunkce pravĂŠ komory nebyla u pacientĹŻ se srdeÄnĂm selhĂĄnĂm se zachovanou ejekÄnĂ frakcĂ nijak vĂ˝jimeÄnĂĄ. © 2021, ÄKS.
