Yini ebangela isifo senhliziyo?

Kuyini ukuhlaselwa yinhliziyo?

Ngokuvamile kuchazwa ngokuthi i-myocardial infarction, ebangelwa ukuvinjelwa kwegazi kwelinye lamagatsha emithanjeni ye-coronary ehambisa igazi emsipha wenhliziyo.

Inhliziyo iyiphampu edinga ukuhlinzekwa kwegazi eligcwele umoya-mpilo njalo ukuze imisipha inikeze imisoco enesibopho somsebenzi wayo.Noma yikuphi ukuntuleka kwegazi (ischemia) kuphazamisa ukusebenza kwemisipha yenhliziyo futhi kungase kuholele ekufeni kwezicubu zemisipha (i-ischemia) i-myocardial infarction).

Imisipha yenhliziyo inekhono lokuzilungisa, inqobo nje uma ukuhlinzekwa kwegazi eline-oxygen ngokushesha kubuyela kokujwayelekile ngokwelashwa okufanele.

Ukuvinjelwa komthambo wenhliziyo okukhulu kwenzeka lapho igazi (elingajikijeli ngokujwayelekile) liphoqeleka ukuba lihlule ngenxa yokuthi umthambo usuke uba mncane.

Isizathu esiyinhloko se-artery stenosis yisifo esibizwa ngokuthi i-atherosclerosis (i-atherosclerosis), inqubo lapho into enamafutha equkethe i-cholesterol (i-plaque) ibeka futhi iqoqwe ngasezindongeni zomthambo.
