Genetické aspekty vzniku kardiovaskulárních onemocnění jsou důležité kvůli jejich významnému přínosu k celkové struktuře srdeční patologie a rozšíření diagnostických možností molekulárních technologií. Cílem studie bylo systematizovat současné znalosti o roli dědičných faktorů ve vývoji kardiovaskulárních patologií a posoudit klinickou účinnost genetických metod pro jejich diagnostiku. Po uplatnění kritérií pro zařazení a vyloučení zahrnoval přehled literatury 60 vědeckých studií. Analýza prokázala, že primární a sekundární strukturální poškození myokardu, srdeční arytmie a aterosklerotické komplikace jsou často způsobeny komplexními polygenními interakcemi spíše než jednotlivými monogenními defekty. Dědičné formy kardiomyopatií jsou spojeny s variacemi v genech sarkomerních a cytoskeletálních proteinů, přičemž klinické projevy se liší v závislosti na přítomnosti dalších modifikujících polymorfismů. Poruchy srdečního rytmu, jako je syndrom dlouhého a krátkého QT, syndrom Brugadových a katecholaminergní polymorfní tachykardie, vykazují vysokou genetickou heterogenitu a neúplnou penetranci. Geneticky determinované hodnoty lipoproteinu(a) (Lp(a)) jsou podstatné v patogenezi nejen aterosklerózy, ale i mnoha dalších onemocnění postihujících kardiovaskulární systém, souvisejících s polymorfismy lokusu Lp(a) na chromosomu 6q27 a ovlivňujících riziko trombotických komplikací. Navzdory prokázané účinnosti metod panelového a exomového sekvenování při identifikaci genetické predispozice je jejich klinické využití omezeno vysokými náklady a nedostatkem jednotných interpretačních kritérií, což omezuje možnost hromadného screeningu a personalizovaného přístupu k léčbě pacientů. © 2026, ČKS.
