La troponine tshuaj yog ib tug cov protein uas nkag mus rau hauv lub Constitution ntawm cov leeg pob txha thiab tswj lawv contraction, suav nrog rau qib ntawm mob plawv.

Nws yog ib qho nyuaj ua los ntawm peb cov proteins: troponins I, -C thiab -T.

Muaj cov duab tshwj xeeb ntawm lub plawv rau troponin T thiab kuv, uas tuaj yeem kuaj xyuas lub plawv puas.

Qhov ntau npaum ntawm cardiac troponins tso cai rau:

• mus ntes a mob plawv,
• kom stratify qhov kev pheej hmoo (prognosis) nyob rau hauv cov neeg uas tau undergone a mob vwm mob hlwb
• mus kuaj a myocardial infarction (lub plawv nres)

Qhov koob tshuaj no yog qhov tseem ceeb rau kev kuaj mob, kev kuaj mob thiab kev saib xyuas ntawm cov mob coronary syndromes, uas xa mus rau tag nrho cov kev mob tshwm sim thaum ib qho ntawm cov hlab ntsha uas muab lub plawv (cov hlab ntsha coronary) raug thaiv tag nrho lossis ib feem. . Myocardial infarction yog ib qho ntawm lawv.

Cov koob tshuaj yog nqa tawm los ntawm kev siv cov ntshav yooj yim. Cov txheej txheem tshuaj ntsuam xyuas yog ua raws li cov tshuaj tiv thaiv uas paub txog cov kab mob plawv ntawm cov troponins sib txawv.

Thaum tsis muaj teeb meem plawv, qhov concentration ntawm troponin hauv cov ntshav yog tsawg heev. Nws yuav tsum tsawg dua 0,6 μg / L (micrograms ib liter).

Ib qho kev nce qib ntawm troponin hauv cov hlab ntsha yog qhov qhia txog kev puas tsuaj rau myocardium, lub plawv cov leeg. Tom qab lub plawv nres los yog txo cov ntshav mus rau lub plawv, lub plawv hlwb necrotize thiab tuag, tso troponins.

Cov no tuaj yeem pom hauv cov ntshav 2-4 teev tom qab pib ntawm myocardial kev nyuaj siab.

Kev nce ntawm troponin hauv cov ntshav kuj tuaj yeem pom hauv:

• bypulmonary embolism,
• de myocarditis (mob myocardium),
• bymob plawv tsis ua hauj lwm,
• bykab mob raum kawg
