La mwoyo scan, kana myocardial scintigraphy, a imaging test iyo inobvumira kuona kunaka kwekudiridza kwemoyo by tsinga dzekoniyoni.

Kana ropa rikafamba zvisina kunaka mutsinga idzi, sepadzinenge dzakavharwa kana kutetepa, tsandanyama yemwoyo (myocardium) haigamuchire oxygen yakakwana. Izvi zvinotungamirira kune zvakasiyana-siyana zvingangove zvakakomba zviratidzo: kurwadziwa muchipfuva, kupfupika kwekufema, kana kunyange kurwisa kwemoyo (ichi ndichocoronary insufficiency).

Scintigraphy inyanzvi yekufungidzira iyo inosanganisira kupa kumurwere radioactive tracer, iyo inopararira mumuviri kana munhengo dzinofanirwa kuongororwa. Nokudaro, murwere ndiye "anobudisa" mwaranzi iyo ichatorwa nemudziyo (kusiyana neradiography, apo mhepo inobudiswa nemudziyo). Iyo scintigraphy inoita kuti zvikwanise kuona kushanda kwenhengo (kwete chete morphology yavo).

Muedzo uyu unoshandiswa pakuongorora chirwere checoronary artery.

Muchirevo chechinyorwa ichi, zvakaenzana nekuita echocardiography (cardiac ultrasound).

Inobvumirawo kuti:

• ipa chiremba mirayiridzo pamusoro pemashandiro ari kuita mwoyo, kukwanisa kwawo kupomba kana kuburitsa ropa
• kuita ongororo yehutano hwemoyo mushure mea myocardial infarction kuona nzvimbo dzeischemia(iyo yakatorerwa oxygen) kana kutsvaga nzvimbo idzi kana paine fungidziro yeangina orHeart Failure
• ongorora njodzi yematambudziko emoyo mune ramangwana, semuenzaniso usati wavhiyiwa, kunyanya kune vanhu vane njodzi (chirwere cheshuga, hypertension, kuputa, nezvimwewo) uye vasingakwanise kuita EKG

Ziva kuti akati wandei marudzi emoyo scintigraphies anogona kuitwa panguva yekuongororwa kwemoyo:

• myocardial perfusion scintigraphy
• Isotope ventriculography kana synchronized angiocardioscintigraphy (MUGA), iyo inopa ruzivo rwakawanda pamusoro pekubuda kwemoyo uye kupomba.

La myocardial perfusion scintigraphy inoitwa mushure mekuedza. Zvechokwadi, kusakwana kweropa muchiitiko chezvinetso pamwero wemakoroni kunoonekwa kunyanya panguva yekuedza.

Inopesana nevakadzi vane pamuviri kana vanoyamwisa. Kutsanya hakudiwi, asi unogona kurairwa kuti usadye chero zvinokurudzira (kofi, tii, nezvimwewo) pazuva rebvunzo.

Kazhinji, iwe unozokumbirwa kuita bhasikoro kana treadmill bvunzo kutanga, pasi pekutariswa kwechiremba wemwoyo. Kana bvunzo iyi ikarambidzwa, chiremba wako anokubaya jekiseni nemushonga unokurudzira moyo sekunge uri kurovedza muviri (dipyridamole, adenosine, dobutamine).

Munguva kana pakarepo mushure mekuedzwa, chigadzirwa chisina kusimba cheradioactive (radiotracer) chinobayiwa mutsinga iri paruoko, iyo inonamira zvakananga pamwero wemoyo.

Pakarepo mushure mekuedza, ipapo panguva yekudzoreredza 15 kusvika 30 maminetsi mushure mejekiseni reradiotracer, iwe unozokumbirwa kurara pasi patafura yekuongororwa, pasi pekamera yakakosha (scintillation kamera) iyo inokutendera kuti utarise radiation inoburitswa ne. mwoyo.

Zvichienderana nemhedzisiro yekutanga yakawanikwa, tinogona kutora mifananidzo mitsva maawa matatu kusvika mana mushure mebvunzo yekutanga, pakuzorora.

Iyo scintigraphy inoita kuti zvikwanise kuburitsa kusaenzana muropa rekupa kumoyo, asiwo kuongorora kushanda kwayo, kunyanya panguva yekuedza.

Zvichienderana nemigumisiro, chiremba wemwoyo acharatidza kurapwa kwakakodzera uye kutevera-kudzikamisa njodzi dzemwoyo.

Dzimwe bvunzo dzinogona kurairwa.
