M'mnyewa wamtima infarction. Kodi kuchitira?

M'mnyewa wamtima infarction - ndondomeko pathological, zochokera kuwonongeka kwa cardiomyocytes ndi malo awo ndi minofu connective mu zotsatira za infarction m'mnyewa wamtima.

Nthawi zambiri, kudwala izi akufotokozera pambuyo infarction m'mnyewa wamtima. Wonongeka kwa minofu mtima, osasamba yobereka magazi, choncho mpweya, mtima amachititsa chitukuko cha infarction m'mnyewa wamtima. Matenda anoxia cardiomyocytes anachititsa zotupa makamaka atherosclerotic wa ziwiya inatsekeratu.

M'mnyewa wamtima infarction - ndi necrosis (necrosis) zigawo kutanthauzira osiyana a minofu mtima. okhulupirika ake wabwezeretsedwa mothandizidwa ndi zophuka pa madera kuonongeka kwa minofu connective. Komabe, nsalu sangakhoze yafupika, imbaenda kusokoneza ntchito mtima: pali kuchepetsa ejection nusu, conduction mtima ndi mungoli, ndi mtima zikumveka kukhala wogontha.

M'mnyewa wamtima infarction amakhala ndi kuwonongeka focal kwa minofu mtima - m'madera chimodzi kapena zingapo amene ali omveka bwino, m'malo ndi minofu connective.

Kukomoka, kudwala izi kuwawonetsera dilation (kukulitsa) wa mtima zipinda hypertrophy (thickening) a minofu mtima. Ngati panali cardio, zizindikiro, kuti amakhala ndi zotsatirazi: Kulephela kugwila olimbitsa thupi, komanso kutopa, kuoneka tachycardia, kufupika kwa mpweya, kupweteka mtima, kutupa (edema kuonekera koyamba pa miyendo m'munsi). Ndi chizindikiro wamba matenda oopsa ndi apamwamba kwambiri kuposa zachibadwa. M'mnyewa wamtima infarction nthawi zina wapezeka ndi maonekedwe kulephera kutchulidwa mtima. A Vuto pafupipafupi matenda ndi permeability osauka Mitsempha, omwe amachepetsa kotunga mpweya ziwalo, komanso kuti minofu kwambiri mtima.

Cardiosclerosis Chithandizo ayenera kuyamba mwamsanga, posachedwapa. Pa gawo lino, njira zosiyanasiyana ntchito. Pakuti kukondoweza kwa mtima, kayendedwe ka mabala ake, mmene kagayidwe cardiomyocyte imachitika mankhwala kuchipatala. Mankhwala kuwonjezera contractility wa myocardium wawo.

Kuchepetsa kunenepa amachepetsa katundu pa mtima. Ngati misa owonjezera ndi chifukwa edematous madzimadzi, m'pofunika kuti atenge okodzetsa kuti kuchepetsa kutupa ndipo, chotero, kulemera.

M'mnyewa wamtima infarction kawirikawiri amafuna alowererepo opaleshoni: kokha pamene kwambiri arrhythmias mtima kapena zotupa inatsekeratu mtsempha wamagazi. odwala amenewa anagwira khazikitsa stents kukuza lumen Mitsempha. Mwina inatsekeratu mtsempha wamagazi kulambalala opaleshoni.

Myocardium ndi magazi zotengera zikhoza kusinthidwa mu buku laling'ono ndipo popanda opaleshoni.

Komanso kalekale kuchotsa infarction m'mnyewa wamtima, chithandizo chingatithandize maselo tsinde. maselo tsinde kulimbikitsa minofu kusinthika ndi ziwiya mtima ndi magazi ndi ziwalo zina ndi zimakhala. Kupatsidwa zina za maselo amenewa outpatient zipatala mu zipatala. Ndi nthenda yotaya magazi kwa iwo kuwafika myocardium, kumene Ufumuyo madera wathanzi. Ndiye, mapulaniwo maselo aithamangitse fibroblasts kuti kupanga mabala, ndi kusiyanitsa mu cardiomyoblast. Motero, pali m'mnyewa wamtima kusinthika kwa 9 - 12 miyezi. Zabwino mphamvu ya mankhwala a infarction m'mnyewa wamtima ndi odwala anati ndipo anatsimikizira ndi maphunziro matenda.
