Pakati pezvinokanganisa mwoyo, aortic stenosis ndechimwe chezvinhu zvakajairika: hutachiona hunosimbiswa mumunhu wese wegumi wemakore makumi matanhatu nemakumi matanhatu nemashanu, uye varume vanohutambura kanomwe kakawanda.
Nenzira yakawanda, stenosis ndeyekudzivirira kweaortic valve, nekuda kweiyo, panguva iyo yechinyakare (systole) yegomba rekupedzisira, kubuda kweropa kubva kune imwe kusvika kunokwira kune aorta kunowedzera kuoma.
Mhando uye zvinokonzera aortic stenosis
Iro tsika yekusiyanisa pakati pekusangana kwemaitiro uye kuwana imwe. Muchiitiko chekutanga, aorta ine mavhavha maviri kana maviri (ejai-matatu), anokonzera kuti aortic isati yasvike, uye kuruboshwe kuruboshwe runofanira kushanda nemutoro mukuru.
Kuwana hutachiona kunovhiringidzwa ne rheumatic processes (kusvika kusvika 10% yematambudziko), ayo anowanzoperekedzwa nekushaya kukwana kana kusimba kwemaster valve. Vechiduku vanowana aortic stenosis nekuda kwerheumatism .
Zviratidzo zve stenosis yeaortic valve inogona kuonekwawo nechekuguma kwe endocarditis, umo mavhavha akabatanidzwa uye anoramba akaoma, achidzikisa lumen.
Muvanhu vakwegura, atherosclerosis kana kuiswa kwe calcium salts (calcinosis) inowanzoonekwa pamagetsi evhavha, iyo inotungamirirawo kuderera kwemwenje.
Zviratidzo zve aortic stenosis
Pazvikamu zvekutanga zvekuvandudzwa kwemararamiro, zviratidzo zve stenosis hazvisati zvaratidzwa, uye zvinowanzowanikwa zvisina kufanira panguva yekuongorora kwemoyo. Kunyangwe mushure mekuongororwa, zviratidzo zvinogona kuita kuti iwe umirire makore mashomanana.
Murwere anonyoresa ne cardiologist uye akacherechedza munguva yechirwere chacho. Nokufamba kwenguva, kuderedza kweaortic valve lumen kunotungamirira kukurumidza kufema uye kuwedzerwa kuneta, kunonyanya kuonekwa panguva yekuita basa. Iko kunonzi kudonhedzwa kwepenosis yeaortic - nzvimbo ye lumen inoderera kusvika pa6-1.2 cm2, asi munhu ane utano huno huwandu huno 2.5-3.5 cm2.
Pachikamu chechipiri chekugadzirwa kwehutachiona (akaratidza stenosis), ukuru hwemarara hunoonekwa kuti hahuna kupfuura 0.7-1.2 cm2. Panguva yekushanda nesimba, varwere vakadaro vanong'un'una nezvechezzinesi uye stenocardia (kurwadziwa shure kwe sternum), kupera kunogona.
Iyi nhanho inotevera yakakosha uye inoshorwa aortic stenosis, inoratidzwa nezviratidzo zvakadai sokucheka, mwoyo wepachimusi uye kunyange kupemha edema. Chiedza chinoderera kusvika ku 0.5-0.7 cm2.
Muchiitiko chacho apo stenosis iri kuberekwa, zviratidzo zvayo zvinotanga kuonekwa mumakore maviri kana matatu ehupenyu, uye hutachiona hunokurumidza kukurumidza.
Kurapa kweaortic stenosis
Kusvika iye zvino, hakuna mishonga chaiyo yehutachiona huno, uye mumatanho ekutanga anongorongedza kukura kwayo.
Muchikamu chekupedzisira, apo kuderera kwe-aortic valve lumen kunoponesa munhu asinganzwisisiki nenzira yakatsanangurwa pamusoro apa, kushandiswa kwemagetsi kunobatsira. Iyo yakaoma zvikuru uye inotyisa, kunyanya kune vechidiki nevakuru. Panguva imwecheteyo, zviratidzo zvinopfuurira zvinoparadza upenyu hwomurwere zvakanyanya - nehukuru hweaorst stenosis huri kurarama makore anenge 3 kusvika ku6.
Imwe nzira yekugadziriswa kwevhavha inonzi valloloplasty. Iyo nzira inosanganisira kuisa muvharovha yevheji ibhodhi duku duku, iyo inopihwa nemhepo. Nokudaro, zvinokwanisika kuwedzera chibvumirano chevhavha, zvisinei, valvuloplasty haisi panjodzi yakawanda kudarika vheji inonzi valve prosthetics.
Lifestyle
Varwere vane aortic stenosis vanopesana mumitoro mikuru. Kukundikana kwemwoyo, kusimbisana nehutachiona hwehutachiona, kunotarisirwa tsika, zvisinei, kugadzirirwa kweboka revasodilators, sekutonga, hazviiti. Kubva pakurwiswa kweAngina kunobatsira nitroglycerin, iyo inofanirwa kupfekedzwa navo.
