Az agyi érbetegségek magas előfordulási aránya indokolja a megkülönböztetett figyelmet, hiszen a stroke-ot a szív- és érrendszeri megbetegedések és a rosszindulatú daganatok után a harmadik leggyakoribb halálozási okként tartják számon világszerte. Az utóbbi évtizedekben jelentős progresszió volt tapasztalható a stroke és általában a cerebro- és cardiovascularis betegség hátterében álló genetikai variánsok azonosításában. Ezeknek a variánsoknak a vizsgálata újfajta szemlélet felé nyitott a betegségek patogenezisének megismerésében; hozzájárulhat a betegség rizikófaktorai elleni küzdelemhez, az optimális jövőképünk szerint a stroke-ra hajlamos egyének kiszűréséhez és gondozásához. Ischaemiás stroke hátterében számos, a haemostasis, a renin-angiotenzin rendszer vagy a lipidmetabolizmus fontos fehérjéit kódoló génekben lokalizálódó genetikai variánst vizsgáltak. Ezeknek a variánsoknak a száma a robusztus genomi asszociációs vizsgálatok megjelenésével és napjainkban is tartó terjedésével ugrásszerűen megnőtt. A szerzők tanulmányukban olyan kutatási eredményeket foglalnak össze, amelyek a személyre szabott medicina és a stroke prevenciója számára fontos mérföldkövek lehetnek. Orv.
