Echocardiography enables non-invasive assessment of many hemodinamical parameters and with the use of tissue Doppler echocardiography (TDE) also LV filling pressure. The ratio between mitral valve early diastolicvelocity (E) and tissue Doppler mural annular early diastolic velocity (Em) is in very good correlation with pulmonary artery wedge pressure. In our study we tried to evaluate the E/Em ratio in unselected population of patiercts with heart failure. Methods 50 patients with heart failure and 30 healthy individuals were included in the study. Standard echocardiographic exam and pulsed wave tissue Doppler was performed of septal border of mitral annulus were performed in all participants. The E/Em ratio was calculated and values compared between both groups. The correlation between E/Em ratio and age was assessed in healthy subjects. Results The E/Em ratio was significantly higher in patients with heart failure then in healthy subjects. The cut-off value 11 had 85% sensitivity and 93% specificity in diagnosing heart failure. There was no statistically significant correlation between E/Em ratio and age. Conclusions By using TDE and E/Em ratio, we can confirm the presence of elevated LV filling pressure in patients with heart failure"},{"@xml:lang":"sl","#text":"Izhodišča Ocena polnilnega tlaka levega prekata (LP) je pogosto potrebna pri klinični obravnavi hemodinamsko nestabilnih bolnikov. Ehokardiografija omogočaneinvazivno oceno številnih hemodinamskih parametrov v srcu, vendar šele uporaba tkivno doplerske ehokardiografije (TDE) omogoča tudi zanesljivejšo neinvazivno oceno polnilnega tlaka LP. Razmerje med zgodnjo diastolično hitrostjo na mitralni zaklopki (E) in zgodnjo diastolično tkivno doplersko hitrostjo mitralnega obroča (E) je dobro povezano z invazivno izmerjenim zagozditvenim tlakom v pljučni arteriji. V naši raziskavi smo poskušali opredeliti pomen razmerja E/Em pri bolnikih s srčnim popuščanjem. Metode V raziskavo smo vključili 50 bolnikov s srčnim popuščanjem in 30 zdravih preiskovancev. Pri vseh smo ob standardni ehokardiografski preiskavi opravili tudi pulzno TDE na septalnem robu mitralnega obroča z merjenjem hitrosti Em. Za vse preiskovance smo izračunali razmerje E/Em in primerjali vrednosti med obema skupinama ter določili mejne vrednosti. Pri zdravih preiskovancih smo ocenili povezavo med razmerjem E/Em in starostjo. Rezultati Razmerje E/Em je bilo pri bolnikih s srčnim popuščanjem statistično značilno večje kot pri zdravih preiskovancih. Mejna vrednost 11 je s 85-odstotno občutljivostjo in 93-odstotno specifičnostjo potrdila diagnozo srčnega popuščanja. Statistično značilne povezave med razmerjem E/Em in starostjo nismo potrdili. Zaključki Tudi pri bolnikih s srčnim popuščanjem lahko s tkivno doplersko ehokardiografijo in razmerjem E/Em potrdimo prisotnost povišanega polnilnega tlaka levega prekata"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-8SM8DYA0","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-8SM8DYA0"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-8SM8DYA0/2f870164-eecd-4a0d-8f19-a0fc20733180/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by-nc/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Slovensko zdravniško društvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-8SM8DYA0/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-8SM8DYA0"}}}}
