Vascular insufficiency

Vascular insufficiency ia lŘlŘ i loko o kahi o 1-2% o ka huina heluna kanaka. Oia ka moku'āina mea mau i kaʻilihune o kekahi maʻi. Ma ka hapanui o hoopii, e hele aku ai i nā maʻi o ka mea'ōnaehana mānowai koko nenoaiu. O nā cardiomyopathy, angina, myocardial infarction, naau mā.

I ka make ana o ka naau Muscle triggers 'aʻe' ana i ke koko lako i ke kino, ma muli o ia kona mea hoʻonāwaliwali maoli nō, a unsatisfactory hana o kona kuleana pili i pumping.

Vascular insufficiency Ua wehewehe aku me ka pathological ano ma a he mea he emi ma ka tonus o ka'ōlohelohe Muscle o ka moku pā. Kēia hoʻonāukiukiʻana mai o hypotension, na kanaka haunaele iloko o ka venous hoʻi a me ke kahe o ke koko.

Vascular insufficiency manawa i iniiaiie lesions 'ano o ka naau e loaa pu ma ka hui, a me ka inevitable naoh moku. Kēia naoh Ua wehewehe aku ma ka uku 'ano. Penei huʻi cardio vascular insufficiency pu ma ka naoh, a ua hoikeia mai ma ka palapala o ka vasoconstriction ma muli o ka hopena o ka pressor maomeka. Ua hiki aku i ka mahuahua ma vascular ia'ku no i kekahi manawa, i kekahi mau mea ulu i loko o ka nui o ke koko, a me ka normalization o ke koko lako i nui nā loko o ke ola. I ka maʻi ano auou caiaiai vasoconstriction mai hypertrophy o ala apuupuu Muscle keena o ka moku pā.

Me ka depletion o ka uku 'maomeka i loko o ka naʻau o ka hoʻokō' ole, vascular insufficiency pili ana. Kēia ho'ēmi i kā ka huinaʻike ākea ia'ku, dramatically hoʻonui i ka poe uuku a aa koko, venules a me capillaries.

ʻaneʻane kela kaʻina hana i loko i ka naau i ka hana strenuously no ka lōʻihi manawa, a mall pōʻino 'ia i loko o ka myocardium, hoʻonāukiukiʻana mai o ka ole o ka naau a me ka ipu. E like me ka hana pono E hoike mai, pinepine ka moku'āina malama ma ke kāʻei kua o na maʻi like coronary artery maʻi, valvular naau maʻi (loaa a me congenital), myocarditis, hypertensive kūlana, cardiomyopathy. Eia hou, i ka maʻi kānāwai i loko o ka maʻi o ka endocrine ano metabolic lesions, lawa no kou kino.

Ka loa pinepine kumu o ka make (80% hihia) iloko o ka mea'ōnaehana mānowai koko maʻi mea coronary artery maʻi.

I ka maʻi ke alakai likeʻole kumu. Hoʻomalu, he ekolu papa kuhikuhiE pūʻulu o etiological aʻe.

Ka mua pūʻulu nā kumumea i loaʻa 'ole i ka pololeiʻino wale i ma ka myocardium. Ua hiki e physical trauma, Nine Inch waiū (e like, lāʻau overdose). Eia hou kekahi, pololeiʻino wale i 'ole e hiki ai, a me ka liluwelo aʻe (toxins, pathogens, parasites).

I ka lua o ka pūʻulu o nā kumu ka loaʻa o nā kumumea i hoonaukiuki i overload o myocardial ooieoeiiaeuiiaiʻano. Mau nā he excessive ulu i loko o ka buke o ka hoʻopā ai ke koko a hiki i ka naau ( "overload nona iho"). Kēia kānāwai ka wā cardiac kiwikā insufficiency, alo extracardiac a me ka intracardiac shunts, a ma ka hypovolemia. overload a myocardial kumu hoomahuahua ma ka ia'ku ma luna o ejection, mai ka lua mai o ke koko ( "puʻe overload") naau. Ma keia hihia, mea'ōnaehana mānowai koko hoʻokō 'ole' e hoʻomōhala ana i loko o ke alo o myocardial hypertrophy. It E e kaulana ia hypertrophy ia lŘlŘ i loko o ke kino 'Oihana, i hāpai mai, pili hana.

A me ke kolu o ka pūʻulu ka loaʻa o nā kumumea e ho ololi i ka hoʻopōʻino diastolic ventricular iie. Keia ano ua kauoha ae la ia e ka emi i ka ho'ākāka 'nui ka ai hoʻolahaʻia ke koko ka leo (iloko o ikaika hawewe a me ke koko poho), a me ka' aʻe 'ia ma diastolic hoʻomaha o ka naau i mīkini'opihia o kona wai i accumulates ma ka pericardium (koko, transudate, exudate).
