La troponin ndiwo protein substance iyo inopinda mubumbiro remitemo ye tsandanyama fiber uye anoronga yavo marwadzo, kusanganisira pamwero we mhasuru yemwoyo.

Iyo yakaoma inoumbwa nemapuroteni matatu: troponins I, -C uye -T.

Kune chaiwo maumbirwo emoyo etroponin T uye ini, anogona kuona kukuvara kwemoyo.

Kuyerwa kwe cardiac troponins inobvumira:

• kuziva a kusagadzikana kwemoyo,
• kurongedza njodzi (prognosis) muvanhu vakapfuura acute coronary syndrome
• kuongorora a myocardial infarction (kumira kurova kwemoyo)

Ichi chipimo chemushonga saka chakakosha pakuongorora, kufungidzira uye kurapa kwekutarisa kweacute coronary syndromes, iyo inoreva kuvhiringidzika kwese kunoitika kana imwe yetsinga inopa moyo (coronary arteries) inovharika yakazara kana muchikamu. . Myocardial infarction ndeimwe yavo.

Muyero wacho unoitwa pachishandiswa sampuli yeropa. Iyo assay tekinoroji yakavakirwa pane masoja ekudzivirira chirwere anoziva mhando dzemoyo dzematroponins akasiyana.

Mukushayikwa kwedambudziko remwoyo, kusanganiswa kwetroponin muropa kwakaderera zvikuru. Inofanira kuva isingasviki 0,6 μg / L (micrograms per litre).

Chero kuwedzera kwehuwandu hwe troponin muropa chiratidzo chekukuvadza kune myocardium, mhasuru yemwoyo. Kutevera kurwisa kwemoyo kana kudzikira kweropa kumoyo, masero emoyo anofenda uye anofa, achiburitsa troponins.

Izvi zvinoonekwa muropa maawa 2-4 mushure mekutanga kwekushungurudzika kwemyocardial.

Kukwirira kwetroponin muropa kunogonawo kuonekwa mu:

• bypulmonary embolism,
• de myocarditis (kuzvimba kwemyocardium),
• bykusingaperi mwoyo kukundikana,
• bykuguma-danho renal chirwere
