Terminologija i dijagnostički kriterijumi Non-Q infarkta miokarda
Univerzitet u Novom Sadu, Medicinski fakultet, Institut za kardiovaskularne bolesti

Sažetak

Non-Q infarkt miokarda predstavlja poseban entitet akutnog infarkta. On se od Q-infarkta miokarda razlikuje ne samo elektrokardiografski, tj. Odsustvom formiranja Q zupca, već patofiziološki, patohistološki, klinički i prognostički. Saznanje da se "transmuralni" ili "subendokardni" ne mogu precizno okarakterisati elektrokardiografskim kriterijumima, dovelo je do zamene ovih patoanatomskih termina elektrokardiografskim. Dijagnoza non-Q infarkta postavlja se prevashodno na osnovu prisustva povećanih srčanih enzima, a tek onda bola u grudima i elektrokardiografskih promena. Mali broj pacijenata može da ima i normalan elektrokardiogram, ali većina ima ili novonastalu elevaciju ST segmenta ili depresiju ST segmenta i/ili negativne T-talase. Budući da se ove promene sreću i kod nestabilne angine pektoris "zlatni standard" za postavljanje dijagnoze non-Q infarkta srca jeste porast biohemijskih markera miokardne nekroze.
