L 'myocardial infarction zvinoenderana nekuparadzwa kwechikamu chetsandanyama yemwoyo inonzi myocardium. Zvinoitika kana, semuenzaniso, a clot inodzivirira kutenderera kweropa senguva dzose kuburikidza netsinga yemwoyo, tsinga inopa ropa kumwoyo. Iyo yekupedzisira inobva yasadiridzwa zvisina kunaka uye tsandanyama yemwoyo yakakuvadzwa.

Myocardial infarction, dzimwe nguva inonzi heart attack kana acute coronary syndrome, inouraya munenge 10% yezviitiko. Pakangoonekwa zviratidzo zvekutanga, zvakakosha kudzivirira rubatsiro. Rubatsiro rwekutanga ruchapihwa muamburenzi uye ipapo kuchipatara kuchave kuri madikanwa. Zvadaro, kutarisirwa kwenguva refu kuchapiwa, kunyanya kudzivisa chirwere chemwoyo mutsva kana kuonekwa kwehutano hwemwoyo. Iyi post-infarction care ichave nekurapa zvinodhaka, kuvandudzwa kwemoyo kana shanduko yemararamiro.

Myocardial infarction inokonzerwa netsinga inovhara, iyo inotungamirira kukushaya oxygenation yemwoyo, uye naizvozvo kuparadzwa kwechikamu chemyocardium. Kunyimwa okisijeni, maseru emhasuru iyi anofa: tiri kutaura nezvazvo necrosis. Iyo myocardium inobata zvishoma, chirwere chemwoyo rhythm chinooneka uye ipapo, kana pasina chakaitwa, mwoyo unomira kurova. Kuti udzivise mhedzisiro iyi inouraya, zvinodikanwa kuvhura arteri nekukurumidza sezvinobvira.

Asi tsinga ingavharika sei? Vane mhosva ndivo atheroma plaques. Kunyanya yakagadzirwa cholesterol, mahwendefa aya anogona kuumba pamwero wemadziro emidziyo yeropa, uye naizvozvo ye coronary arteries, iyo inopa mwoyo. Kana iyo atheromatous plaque inoputika uye ichiita kuvhara, inogona kukonzera myocardial infarction.

Zviratidzo zvemyocardial infarction zvakanyatso hunhu: kurwadziwa muchipfuva, kupfupika kwekufema, kutuka, kurova kwemoyo kusingaite, kusagadzikana muruoko kana ruoko, nezvimwe.

Kunyange zvakadaro variko infarct silent. Munhu anacho hapana kana zviratidzo zvaanoona. Kurova kwemoyo wakanyarara kunogona kusaonekwa asi kunowanikwa panguva yebvunzo senge EKG. Ichi chirwere chemoyo chinyararire chinowanzobata vanhu vanorwara nechirwere cheshuga.

dzosa : Mwoyo ipombi inogovera ropa kunhengo dzese. Iyo myocardium inokonzera kudiridza muviri neropa uye naizvozvo oksijeni. 

Kuwanda

Kune muFrance angangoita 100.000 myocardial infarction pagore. Vanopfuura 5% yeavo vakabatwa vaizofa mukati meawa, ingangoita 15% mugore rinotevera. Huwandu hwevanhu vanofa uhwu hwakadonha zvakanyanya mumakore gumi, kunyanya nekuda kwekuteerera kweSAMU uye nekugadzwa kweanopindira cardiology masevhisi. Nhamba dzeUS dzinotaura nezve10 zviitiko zvepagore uye 8000.00 kusvika 90% kupona kwevarwere vari muchipatara mushure meiyo myocardial infarction.

chirwere

Zviratidzo zvechirwere chemoyo zvinowanzoita zvakanyanya uye zvinobvumira chiremba kuti aite chirwere nokukurumidza. Kuongororwa uku kuchasimbiswa nekuongororwa kwakasiyana-siyana uye bvunzo senge electrocardiogram. Iyo ECG inobvumira kuona kweiyobasa remagetsi yemoyo uye nekudaro, kuona kusagadzikana. Icharatidza kana chirwere chemoyo chatanga kana kuti chiri kuitika. Kuongororwa kweropa kuchaona kuvepo kwema enzymes emoyo muropa anoratidza kukanganisa kune chikamu chemoyo. X-ray inogona kudikanwa, kunyanya kuve nechokwadi chekuti mapapu haabatike. A coronary angiography, x-ray iyo inobvumira kuratidzwa kweiyo coronary arteries, inogonawo kuita kuti zvikwanise kuona kuderera kwedhayamita yeiyi tsinga uye kuvapo kweatheromatous plaque.

Zvinokonzera

Kuvapo kwe atheroma plaque, inoumbwa zvikurukuru necholesterol, inogona kutsanangura chitarisiko chehosha yemwoyo. Iri dombo rinogona kuvhara tsinga yemwoyo uye kudzivirira mwoyo pakupa ropa rakakodzera.

Kurwiswa kwemoyo kunogonawo kuitika semugumisiro weimwe mhando ye spasms pamwero wecoronary artery. Kuyerera kweropa kunobva kwavhiringwa. Iyi spasm inogona kukonzerwa nemushonga wakaita secocaine. Inogonawo kuoneka ichitevera kubvaruka mutsinga yemwoyo kana kana kubuda kweropa kwanyanya kudzikira, kana paine kuderera kweBP semuenzaniso, inonzi hypovolemic shock.

Matambudziko

Matambudziko echirwere chemoyo anosiyana zvichienderana nekuwanda kwenzvimbo yemhasuru yemoyo yakabatwa nechirwere chemoyo. Iyo yakakura nzvimbo, iyo yakanyanya kuoma matambudziko. Munhu angadaro arrhythmia, kureva kuvhiringidzika kwemwoyo, kukanganisa kwemwoyo kana kunyange matambudziko ane imwe yevhavha yemwoyo, valve inogona kunge yakakuvadzwa panguva yekurwisa. Chirwere chemoyo chinogonawo kuomeswa nesitiroko. Chirwere chemoyo chitsva chinogonawo kuitika.

Ngozi yezvinetso ichaongororwa kuburikidza nekuongorora kutsva: ECG, ultrasound, coronary angiography, scintigraphy (kuongorora kushanda kwemwoyo) kana kuongorora kunetseka. Kurapa kwezvinodhaka kuchanyorwawo.
