Abstract

Za razliku od konvencionalnog Dopplera koji mjeri samo globalnu funkciju miokarda, nova ehokardiografska metoda - tkivni Doppler ima mogućnost procjene regionalne i globalne funkcije miokarda. Budući da tkivni Doppler ima veliku vremensku i prostornu rezoluciju kojom se može dokazati vremenska i prostorna nehomogenost u gibanju miokarda u dijastoli, cilj ovog rada je odrediti može li se tkivnim Dopplerom utvrditi postojanje dijastoličke disfunkcije u hipertenzivnih bolesnika, dok su parametri standardne ehokardiografije, koja se danas primjenjuje u praksi, još normalni.
U ovom radu pokazali smo da je regionalna dijastolička disfunkcija mjerena uz pomoć TDI prvi znak oštećenja miokarda uslijed arterijske hipertenzije, dok su parametri globalne dijastoličke funkcije mjereni konvencionalnim Dopplerom kao i TDI još nepromijenjeni. Također, registrirane su i promjene parametara u kasnoj dijastoli kod bolesnika s nereguliranom arterijskom hipertenzijom koji imaju već izraženu globalnu dijastoličku disfunkciju. Dobiveni rezultati ukazuju na potencijalno veliki značaj TDI u dijagnozi i ranom otkrivanju hipertenzivnog oštećenja funkcije miokarda, kao i u praćenju uspješnosti liječenja hipertenzivnih bolesnika.

Abstract (english)

A new echocardiographic method, tissue Doppler imaging, differs from the conventional Doppler which measures only global myocardial function in that it can assess regional and global myocardial function. Since tissue Doppler has a high temporal and spatial resolution which can identify temporal and spatial inhomogeneity of myocardial motion in diastole, the aim of our work was to establish whether tissue Doppler can identify diastolic dysfunction in hypertensive patients, while the currently used standard echocardiographic parameters are still normal.
We showed that regional diastolic dysfunction measured with TDI was the first sign of myocardial damage due to arterial hypertension, while the parameters of global diastolic dysfunction measure with conventional Doppler and TDI were still normal. In addition, in patients with uncontrolled arterial hypertension who already had marked global diastolic dysfunction we registered also the change of parameters in late diastole. Our results indicate a potentially great importance of TDI in diagnosis and early detection of hypertensive myocardial function impairment, as well as in the follow-up of treatment success in hypertensive patients.
