Ukuqina kwamathishu yomthambo i-aorta nasemiphumeleni yaso

ukuqina kwamathishu yomthambo i-aorta (isifo sokuqina kwemithambo yegazi) - isifo onesifo esilazayo wabonakaliswa lipid kokuziphatha ku ulwelwesi kwangaphakathi le-aorta ne ekwandeni ezicutshini abaningi babephephile ezindaweni ezithintekile. It kubangelwa olugcwele bomkhumbi igazi, okwandisa kwabantu nezindonga zayo, kwezinye izimo, isifo sokuvuvukala kwemithambo Umthambo.

Kukhona ngokuvamile kusukela yomthambo i-aorta sclerosis iziyaluyalu olinganise oketshezini olungenambala lwegazi amakilasi ezahlukene lipoproteins. Ezinye zazo neqhaza ukudluliswa cholesterol odongeni isitsha, kuyilapho abanye ithiye le nqubo. Njengomthetho, ukungalingani lipoproteins sitholakala ngofuzo, isuka kwesinye isizukulwane iye kwesinye. Mhlawumbe ukubukeka atherosclerosis akuthola ukudla esiningi ukudla nge wokuqukethwe lelisetulu cholesterol, ezifana ezilwane. Yomthambo i-aorta sclerosis ngokuvamile kwenzeka kubantu abane-high blood pressure, ukukhuluphala, ukubhema kanye ukungawuvivinyi umzimba.

Ngo esigabeni sokuqala lesi sifo ngesikhathi udonga engaphakathi le-aorta, ikakhulukazi thoracic ingxenye, avele izindawo aphuzi flat yobukhulu obuhlukahlukene. Amachashaza cholesterol obanika umbala. Ngemva kwesikhashana eziningi lipid amabala uncibilike futhi iphele, kodwa ezinye, kunalokho, sikhule, bangazihluphi isikhala esikhulu.

Wanabalalisela lipid isisindo uya kuzo zonke izindawo. Ngo le-aorta selinqunyiwe. Umnqopho eyinhloko ukukhula ngaphakathi komgodi we esitsheni kubangela odongeni engaphakathi cholesterol zingcwecwe. Emva kwesikhathi ziqhume ezicutshini angabe esakwazi nokunwebeka futhi abangele ukuvaleka umzimba conductive kwegazi.

Ngaphakathi e-plaque kanye izinqubo engelapheki. Proliferation Imbondela akuhileli nokukhama ka imithambo yegazi ukusuthisa aorta ngokwayo, okubangela kumiswa izindawo necrotic kanye ukunwetshwa izicubu ngaphakathi uqweqwe. Kobuningi encane necrotic foci Fusion kuholela atheromatosis ebanzi. Ukunqotshwa ungqimba phakathi isitsha igazi incipha kuyaqina kanye castle yayo odongeni, okuyinto imbangela useshonile, lapho indawo ayikwazi ayifakiwe ukudabuka yomthambo i-aorta.

Emtholampilo, lesi sifo kubonakala kuyinto nezimo kakhulu, nezibonakaliso ziyahlukahluka kuye inqubo kwasendaweni. Ukunqotshwa kwe-nemithambo yegazi yenhliziyo sivezwe ephula inhliziyo, obhekwe yenhliziyo Umthambo isifo, pectoris angina, arrhythmias inhliziyo futhi isilethikusebenza. Long ischemia fudlana kanye multi-infarct senhliziyo esilimele, kungabangela ukudabuka. Endaweni yabo akhiwa zezinzwa izicubu nezibazi (cardio). ejection legazi ngesikhathi ukugeleza onjalo ongatheni, ukuhluleka kwenhliziyo eba.

Sclerosis le-aorta kungenzeka imbangela isifo sokuvuvukala kwemithambo yakhe, okuyinto libhekene kamanye bomkhumbi igazi. Ngenxa yalokho, ecindezeleke nezinye izitho eseduze, ukusebenza kwabo siphukile. Kwezinye izimo, delamination kwenzeka lapho isifo sokuvuvukala kwemithambo futhi ukudabuka we lesion yomthambo i-aorta.

Sclerosis kwemithambo yegazi letiphakela igazi ebuchosheni, ububonisa ukwehla inkumbulo yomuntu, ikakhulukazi emicimbini eziye zenzeka kamuva. Lesi sifo kuhambisana isiyezi, izinguquko ebuntwini lesiguli. It is waphawula yini ukuthi abantu ukonga nalesi sifo liphenduka ungoqo, kungokwemvelo iba slabodushnym.

Ukuzibandakanya ikhadi besisu imithambo ephelezelwa ubuhlungu esiswini (angina emathunjini). Atherosclerotic semithambo mesenteric imithambo uphela wamathumbu necrosis ndawo. Emtholampilo ke kubonakala nobuhlungu obukhulu endaweni esiswini, futhi ukuvimbela pheshana emathunjini.

Lena kuphela ingxenye encane ukubonakaliswa sokugembula kubangelwa ukuqina kwamathishu yomthambo i-aorta. Ngenxa yokuthi aphathe kakhulu lezi zifo kunzima futhi kuyabiza, ukunakwa main kufanele ikhokhwe ekuvimbeleni lokhu isifo esithena amandla.
