La i-troponine is a amaprotheni ongena kumthethosisekelo we imicu yemisipha futhi elawula yabo ukusikwa, kufaka phakathi ezingeni le- imisipha yenhliziyo.

Kuyinkimbinkimbi eyenziwe ngamaprotheni amathathu: ama-troponin I, -C no -T.

Kunezimo ezithile zenhliziyo ze-troponin T nami, ezingathola ukulimala kwenhliziyo.

Umthamo we-troponins yenhliziyo uvumela:

• ukuthola i- ukukhubazeka kwenhliziyo,
• ukwehlukanisa ubungozi (ukubikezela) kubantu asebeke bathola a i-acute coronary syndrome
• ukuxilonga a i-infarction ye-myocardial (isifo senhliziyo)

Lokhu kukala kubalulekile ekuxilongweni, ekubikezelweni nasekuqapheni ngokwelashwa kwama-syndromes abukhali we-coronary, abhekisele kuzo zonke izinkinga ezenzeka lapho omunye wemithambo ehambisa inhliziyo (imithambo yegazi) ivinjwe ngokuphelele noma ngokwengxenye. . I-infarction ye-myocardial ingenye yazo.

Umthamo wenziwa ngesampula elula yegazi. Inqubo yokuhlola isuselwa kuma-antibodies abona izinhlobo zenhliziyo zama-troponin ahlukile.

Uma ingekho inkinga yenhliziyo, ukugxila kwe-troponin egazini kuphansi kakhulu. Kufanele ibe ngaphansi kuka-0,6 μg / L (ama-micrograms ngelitha ngalinye).

Noma yikuphi ukwanda kwezinga le-troponin egazini kuyisibonakaliso sokulimala kwe-myocardium, isicubu senhliziyo. Ukulandela ukuhlaselwa yinhliziyo noma ukwehla kokutholakala kwegazi liye enhliziyweni, amangqamuzana enhliziyo ahlanganisa futhi afe, akhiphe ama-troponin.

Lezi ziyatholakala egazini amahora angama-2-4 ngemuva kokuqala kokucindezeleka kwe-myocardial.

Ukuphakama kwe-troponin egazini kungabonakala naku:

• byi-pulmonary embolism,
• de i-myocardite (ukuvuvukala kwe-myocardium),
• byukwehluleka kwenhliziyo okungapheli,
• byisifo se-renal sokugcina
