I-Troponin: yini isivivinyo futhi usho ukuthini umphumela

• Ukwenza isivivinyo nini
• Kusho ukuthini umphumela

Ukuhlolwa kwe-troponin kwenziwa ukuhlola inani lamaprotheni we-troponin T kanye ne-troponin I egazini, akhishwa lapho kunokulimala kwemisipha yenhliziyo, njengalapho kwenzeka ukuhlaselwa yinhliziyo, ngokwesibonelo. Uma kukhulu ukulimala kwenhliziyo, nenani lalawa maprotheni asegazini liyanda.

Ngakho-ke, kubantu abaphilile, ukuhlolwa kwe-troponin akuvamisile ukukhomba ubukhona bala maprotheni egazini, kuthathwa njengomphumela omubi. Amanani ajwayelekile we-troponin egazini yile:

• I-Troponin T: 0.0 kuya ku-0.04 ng / mL
• I-Troponin I: 0.0 kuya ku-0.1 ng / mL

Kwezinye izimo, lokhu kuhlolwa kungabuye ku-ode nokunye ukuhlolwa kwegazi, njengokulinganisa kwe-myoglobin noma i-creatine phosphokinase (CPK). Qonda ukuthi ukuhlolwa kwe-CPK kwenzelwe ini.

Ukuhlolwa kwenziwa ngesampula segazi esithunyelwa elebhu ukuze sihlolisiswe. Kulolu hlobo lokuhlaziywa kwemitholampilo, akukho ukulungiselela okudingekayo, njengokuzila noma ukugwema imishanguzo.

Ukwenza isivivinyo nini

Lokhu kuhlolwa kuvamise uku-oda udokotela uma kukhona okusolisayo ukuthi kuhlaselwe yisifo senhliziyo, njengalapho izimpawu ezifana nobuhlungu besifuba obunzima, ukuphefumula kanzima noma ukuncinza engalweni yangakwesobunxele, ngokwesibonelo. Kulezi zimo, ukuhlolwa kubuye kuphindwe amahora angama-6 nama-24 ngemuva kokuhlolwa kokuqala. Bheka ezinye izimpawu ezingakhombisa ukumelwa yinhliziyo.

I-Troponin iyimpawu eyinhloko yamakhemikhali esetshenziselwa ukuqinisekisa i-infarction. Ukugxila kwayo egazini kuqala ukukhuphuka amahora angama-4 kuya kwayi-8 ngemuva kokuhlaselwa yifarasi bese kubuyela ekugxileni okujwayelekile ngemuva kwezinsuku ezingaba yishumi, kukwazi ukukhombisa udokotela ukuthi kwenzeka nini ukuhlolwa. Yize iyimpawu eyinhloko ye-infarction, i-troponin ivame ukukalwa kanye nezinye izimpawu, njenge-CK-MB ne-myoglobin, okugxila kwayo egazini kuqala ukukhuphuka ihora eli-1 ngemuva kwe-infarction. Funda kabanzi ngokuhlolwa kwe-myoglobin.

Ukuhlolwa kwe-troponin nakho kungalawulwa ngenxa yezinye izimbangela zokulimala kwenhliziyo, njengasesimweni se-angina esiya siba sibi ngokuhamba kwesikhathi, kepha lokho kungakhombisi izimpawu ze-infarction.

Kusho ukuthini umphumela

Umphumela wokuhlolwa kwe-troponin kubantu abaphilile awuhle, njengoba inani lamaprotheni akhishwe egazini liphansi kakhulu, ngokungatholakali okuncane noma ukungatholakali. Ngakho-ke, uma umphumela ungemuhle emahoreni ayi-12 kuya kwayi-18 ngemuva kobuhlungu benhliziyo, mancane kakhulu amathuba okuthi kuvele isifo senhliziyo, futhi ezinye izimbangela, ezinjengegesi eyeqile noma izinkinga zokugaya ukudla, kungenzeka kakhulu.

Lapho umphumela ulungile, kusho ukuthi kukhona ukulimala noma ushintsho ekusebenzeni kwenhliziyo. Amanani aphakeme kakhulu ngokuvamile ayisibonakaliso sokuhlaselwa yinhliziyo, kepha amanani aphansi angakhombisa ezinye izinkinga ezinjengalezi:

• Ukushaya kwenhliziyo kushesha kakhulu;
• Umfutho wegazi ophezulu emaphashini;
• Embolism yamaphaphu;
• Ukwehluleka kwenhliziyo yokucinana;
• Ukuvuvukala kwemisipha yenhliziyo;
• Ukuhlukumezeka okubangelwa izingozi zomgwaqo;
• Isifo sezinso esingalapheki.

Imvamisa, amanani we-troponin egazini ayashintshwa cishe izinsuku eziyi-10, futhi angahlolwa ngokuhamba kwesikhathi ukuqinisekisa ukuthi isilonda selashwa ngendlela efanele.

Bona ukuthi yiziphi izivivinyo ongazenza ukuhlola impilo yenhliziyo yakho.
