Olubanzi isilethikusebenza: ubunjalo zokugula, izifo, izimpawu kanye nemiphumela.

Izifo ezihlobene esimiso senhliziyo nemithambo yegazi, namuhla okuholela inani lokufa. Imvamisa umdlavuza zokugula kakhulu ephansi ukuthi enomqondo uchaza ukubaluleka inkinga uphethwe ngesikhathi esifanele kanye nokwelashwa. Kodwa i olunzulu senhliziyo, ezithinta izikhungo ezinkulu imisipha yenhliziyo, uya ngokuya uba ovamile kubantu abangaphezu kweminyaka engu-iminyaka engu-40. Ukuze zihlanganisa olubanzi infarction ventricular septal, anterior kanye posterior udonga i-ventricle engakwesobunxele, okuyinto ukuphazamisa kakhulu ngokusuka enhliziyweni. Kulokhu, it unesifo hhayi kuphela imisipha yenhliziyo ngokwayo, kodwa umzimba wonke baliklasi lonkhe hemodynamics.

Massive attack inhliziyo kungenziwa okubangelwa pathologies ezilandelayo:

• isifo sokuqina kwemithambo yegazi kwemithambo yegazi,

• amahlule,

• spasm nozwela yegazi wechibi.

Ingqondo a massive attack inhliziyo izici ubhekwa ukucindezeleka ngokomzimba, injabulo ngokomzwelo noma ukucindezeleka. Basuke lwenteke ngokusebenzisa uchungechunge izinguquko sokugembula e imisipha yenhliziyo.

Lo mshini isilethikusebenza

Mshini ukuhlaselwa isifo senhliziyo zingachazwa kanje: njengoba isifo sokuqina kwemithambo yegazi kwemithambo yegazi yenhliziyo iyehlisa ukugeleza kwegazi, ingxenye kwezicubu uhlangabezana hypoxia - yokushodelwa umoya. Lesi simo isivele labizwa ngokuthi ischemic isifo senhliziyo (isifo senhliziyo) futhi esibonakala ngokuqina khona-plaque atherosclerotic ukuvala inesikhala futhi lwemithambo sclerosis. Lapho ukuzikhandla umfutho ukugeleza kwegazi kumele lenyuke, inqobo nje uma izindlela compensatory zomzimba.

Ngakho endarterium kukhona ngaphansi okuyinto qwembe kancane overstrains lapho platelet buthelela ngokushesha. Ngakho, ihlule legazi, elibuye unciphise mafutha anciphisa isikhala esingaphakathi kwemithambo yegazi futhi kunciphisa ukugeleza kwegazi ngabo. Ngenxa yalokhu, izindawo infarction zihlupheka ngenxa yokuntuleka oksijini, esiyingxenye focus ngemuva kokuhlaselwa yisifo senhliziyo. Kufanele kuqashelwe ukuthi nale indlela ukuqaliswa necrosis ischemic yenqubo kuyoba mikhulu, ngakho-ke, isiguli uzothola umphumela infarction olubanzi esivimba amanzi.

izimpawu yinhliziyo

Iziguli cishe ngokushesha baqala ukuzwa acute kakhulu esivuthayo ubuhlungu ngemuva breastbone, okuyinto akakhishwanga umthamo owodwa we-nitroglycerin. Uma kabusha nitroglycerin abangela nokuncipha ukushuba ubuhlungu, futhi imizuzu engaphezu kwengu-20, kufanele kube Akungabazeki e isifo senhliziyo, okuyinto njalo kwenza ukuthi kube nesidingo ukubiza i-ambulensi.

Ukuxilongwa nemiphumela yokuhlaselwa massive attack inhliziyo

Lapho lesi sifo kwezidingo inpatient iyunithi liyadingeka. Kube oyokwenziwa izinyathelo zokuxilonga ukucacisa Ihlahlubo ukususwa izimpawu ezibuhlungu. ECG Ukuziphatha ngeke ukucacisa ubunjalo lesion futhi umthamo yayo. Ngakho infarction olubanzi zinezikhathi izinguquko eziningi ku ECG. Futhi olwenziwa igazi ukuhlaziywa kwamakhemikhali, okuyinto kuyokwembula nakomaka kwemisipha inhliziyo. Indlela ukwambulwa kakhulu ukuxilongwa yisifo senhliziyo isikhathi sokuqala inqubo ECG kanye ultrasound, ezibonisa izindawo gipodinamichnye azisetshenziswa ukusikwa. Lokhu kuyoba focus ngemuva kokuhlaselwa yisifo senhliziyo, ivolumu zazo kungabonwa yiwo wonke izindlela wezinsimbi ukuxilongwa. Kungaba wokuthinta izindawo ezinkulu muscle ukubabuyisela esephelelwe umsebenzi.

Ngakho, imithelela kokuhlaselwa yisifo senhliziyo okubi inhliziyo ingaba le nowokudatshukelwa kakhulu - izicubu zenhliziyo uyomane abune away kule ndawo kwakhiwa isibazi. In esigabeni okukhulu olubanzi esivimba amanzi ukugeleza kwegazi iqala ukuba baveze ukuthi ukuntuleka kwesokunxele umbuthano, futhi ekukhanyeni yobuthakathaka i-ventricle engakwesobunxele futhi ukunciphisa ukulahleka ingxenye enkulu imisipha uqala stagnate igazi. Lokhu kungababangela edema yamaphaphu futhi ukufa okuzumayo. Kodwa kulokhu, ekwelashweni imisiwe esibhedlela, ngoba esifike ngesikhathi (amahora kungakadluli 4 lapho kuqala izimpawu zobuhlungu) ukusetshenziswa thrombolytic Ungayibuyisa ukugeleza kwegazi futhi sinciphise umonakalo izicubu. Kuphela ukungena ngesikhathi esifanele has yithuba elihle kakhulu ukunciphisa ivolumu izilonda, nobukhali izimpawu, kanye nokusindisa izimpilo nesineke.
