Ukubhema Kunzima Kwintliziyo
I-atherosclerosis iyisifo esisongela ubomi apho i-cholesterol, i-waste cell, i-calcium, kunye nezinye izinto ezinamafutha zifakwe kwi-binet wall walls. Ezi zimpofu, eziluhlaza, ezibizwa ngokuba yi-plaque, zakha phezu kwexesha, zivimba ukuhamba kwegazi lakho. Ukuba utshaya, ubhekana nobungozi obuninzi be-atherosclerosis, ukuhlaselwa yintliziyo, kunye nesifo.
Ukuqonda i-Atherosclerosis
Eyaziwa nangokuthi ukuqina kwemithambo, i-atherosclerosis iqala ngokuqala ebomini kwaye iyaqhubeka ngokukhawuleza njengoko uneminyaka yobudala. I-atherosclerosis iyakuthintela imirhobho ephakathi kunye nemibutho emzimbeni. Inzululwazi ezininzi zikholelwa ukuba umonakalo ekupheleni kwe-endothelium, umgca wecala lomda, apho i-atherosclerosis iqala khona. Ukulimala ekupheleni kwe-endothelium kuvumela i-plaque ukwakha kunye nendawo yeendonga zakho, kwaye njengoko kunjalo, ukuhamba kwegazi kuphephe kwaye ukunikezelwa kwe-oksijini emzimbeni wakho kuyahla.
Iimpembelelo zeAtrosclerosis
I-Plaque ingahlukana kwaye ibangele i-blood clots (thrombus). La macala egazi angaphuma kwaye afake igazi lakho, ukulala kwelinye inxalenye yomzimba wakho, ngamanye amaxesha uvimba ngokupheleleyo ukuhamba kwegazi, okubizwa ngokuba yi-embolus.
Izibilini ezivuthayo ezivimba ukugeleza kwegazi entliziyweni yakho kubangela ukuhlaselwa kwentliziyo. Ukuba zivimbela ukuhamba kwegazi kwingqondo yakho, zibangele i-stroke.
Ukuba igazi ligeleza kwiingalo kunye nemilenze yakho kuncitshisiwe, kunokukwenza ube nobunzima bokuhamba kwaye ekugqibeleni uholele ekugqibeleni.
Iingxaki zeAtrosclerosis
Kukho izizathu ezintathu ezibonakalisiweyo zokuthi i-atherosclerosis, kuquka:
- I-cholesterol ephakamileyo kunye namanqanaba e-triglyceride: Amanqanaba aphezulu e-cholesterol kunye ne-triglycerides egazini lakho abangela umonakalo ekupheleni kwe-endothelium yakho. Ezinye i-cholesterol iyimfuneko, kunye nomzimba wakho ngokuqhelekileyo uvelisa uninzi lwezinto ezifunayo kwisibindi sakho. Enye imvelaphi ye-cholesterol ivela kwi-fat fat and iyaziwa ngokuba yi-LDL okanye "i-cholesterol" embi. Nangona imizimba yethu idinga i-cholestolol ye-LDL, ubuninzi bayo bunokunyusa ama-cholesterol akho ngamanqanaba kwaye kukubeka engozini yokuthwala i-atherosclerosis kunye / okanye ukuhlaselwa kwentliziyo. Ukutya okuvela kwizilwanyana, ezifana nenkukhu, amaqanda, iimveliso zobisi, inyama yeenkomo, kunye neengulube, ziqulethe i-cholesterol. Ukutya okuvela kwizityalo akuqukethe i-cholesterol.
- Uxinzelelo lwegazi oluphezulu: uxinzelelo lwegazi lubangelwa yimikhosi emibini. Enye ingcinezelo eyenziwe yintliziyo yakho yokupompa igazi ngokusebenzisa inkqubo yakho yokujikeleza. Enye ingamandla okuxhatshazwa kwemibhobho njengoko igazi lakho lihamba ngayo. Xa intliziyo yakho iyaphupha, iqhube igazi ngeemithalo ezinkulu kunye nakwiimitha ezincinci zegazi, ezibizwa ngokuba yi-arterioles. I-arterioles iyakwazi ukukhawuleza okanye yokwandisa, kwaye xa iyenzayo, ukunyanzelisa ukuhamba kwegazi kuchaphazelekayo. Okubunzima kunokuba igazi liqhume, ukuphakanyiswa kwengcinezelo yegazi kuya phezulu. Xa uxinzelelo lwegazi oluphezulu luya kulandelwa ixesha elide kwaye intliziyo yakho inyanzelekile ukuba iphambanise nzima ukuba igazi liphume, umphumo udla ngokugqithiseleyo kunye nobuthakathaka benhliziyo. Uxinzelelo oluphezulu lwegazi lubuhlungu imirhobho yakho kunye ne-arterioles ngokuhamba kwesikhathi. Ziba nzima kwaye zikhuni, zibeka ingozi kwi-atherosclerosis.
- Umsi wecuba: Umsi wesigaretta uphucula iimeko ezimbini ezibangelwa ngasentla kwi-atherosclerosis ngeendlela ezilandelayo:
- I-Cholesterol: Iibhoksi zentambo yengqumbo zinciphisa i-cholesterol yakho ye-lipoprotein (i-HDL okanye "i-cholesterol" enhle) ngelixa iphakamisa amanqanaba e-low-density lipoprotein cholesterol (i-LDL okanye "i-cholesterol embi").
- I-Nicotine kunye ne-carbon monoxide: I- nicotine kunye ne- carbon monoxide ekumotheni umsi wokubhema u-endothelium wakho, ubeka isigaba sokwakhiwa kwe-plaque.
- Umxinzelelo ophezulu wegazi: Nangona ukutshaya ugwayi kungabangela ukuba uxinzelelo lwegazi oluphezulu, ukuba ubumnyama kwaye unomdaka ophezulu, ukutshaya umonakalo kunokunyusa umngcipheko wexinzelelo olubi, uhlobo oluyingozi loxinzelelo lwegazi. Ukubhema kunzima entliziyweni.
Akukaze Kuze Kuphele Ukuyeka
Ukuba utshaya kwaye ucinga ngokuyeka, khumbula, akukaze kuphele ukuyeka ukutshaya. Kungakhathaliseki ukuba uneminyaka engakanani okanye ubuninzi kwiminyaka osuyiyo, uphando luye lwabonisa ukuba umzimba wakho uza kuqala inkqubo yokuphulukisa kwiminyaka engama-20 yesigarethi sakho sokugqibela .
Ngonyaka owodwa wokuyeka ukutshaya, umngcipheko we-coronary artery disease uhlahlela kwisiqingatha somntu otshaya. Kuphakathi kweminyaka emi-5 ukuya kwe-15 yokuyeka, isifo sakho se-coronary kunye nokuphazamiseka kwengozi ye-stroke kuya kwabangaboniyo.
