Angina pectoris, amatchedwanso nangula ndi matenda a mtima omwe amayambitsa kupweteka pachifuwa. Ululu umenewu umawonekera pamene mtima ulibe mpweya wabwino chifukwa cha kuchepa kwa mtsempha wamagazi (komwe kumabweretsa magazi okosijeni kumtima).

Kuyamba kwa angina kungakhale kogwirizana ndi kupanikizika kapena khama. Koma imathanso, nthawi zambiri, imachitika popuma.

Kupweteka komwe kumachitika chifukwa cha angina pectoris ndi kukakamira (kumverera kuti chifuwa chagwidwa mu a Makamu, ndiyeno timalankhula za kupweteka kwapang'onopang'ono), kuzimitsidwa kapena kuyaka. Ululu umenewu, womwe umatsagana ndi kugunda kwa mtima kapena kupuma movutikira, kaŵirikaŵiri umatha mkati mwa mphindi zoŵerengeka, odwalawo akagona kapena kupuma. Mankhwala ena (trinitrin) angathandize kuchepetsa.

Ululu nthawi zambiri a chenjezo : mtima umasonyeza kuti uli ndi mpweya wochepa komanso ukumva ululu. Angina pamapeto pake ndi chizindikiro cha vuto lalikulu la mtima lomwe likubwera, makamaka matenda a mtima (MI kapena myocardial infarction).

Pamaso pa angina pectoris, zoopsa mwachitsanzo, matenda a mtima amakhala okwera kwambiri. Angina pectoris pamapeto pake akhoza kukhala gawo loyamba la matenda a mtima.

Choncho ndikofunikira, zizindikiro zoyamba kuonekera, kuti ziyambe mwamsanga zina ndi kukaonana ndi dokotala mwachangu, ndiye katswiri wamtima kuti akamuyezetse kwathunthu. Otsatirawa adzatsimikizira matenda a angina kudzera muzofufuza zosiyanasiyana zachipatala, kupeza zifukwa zake ndikupereka chithandizo ngati kuli kofunikira.

Angina pectoris sayenera kunyalanyazidwa. Kuyamba kwa ululu kuyenera kufotokozedwa, zizindikiro zochenjeza zimadziwika. Kuwongolera, kuyang'anira ndi kuchiza angina pectoris kumathandiza kupewa zovuta zina zamtima. Kuonjezera apo, ngati ululuwo umakhalapo kapena uli wovuta kwambiri, ndikofunikira kuti mulankhule ndi SAMU (15 kapena 112). Munthu akhozadi kuvutika osati ndi angina koma kuchokera mtima myocardium.

Kukula

Angina pectoris ndizovuta kwambiri wamba. Zingakhudze oposa 10% ya opitilira 65s ku France.

Mitundu yosiyanasiyana ya angina pectoris

Pali mitundu yosiyanasiyana ya angina, ena ndi ululu umene umadutsa mofulumira, ena amapezeka mwadzidzidzi, osagwirizana ndi kupsinjika maganizo kapena kuchita masewera olimbitsa thupi. Choncho, mu otchedwa angina pectoris khola,zowawa zimakhalabe zomwezo pakapita nthawi. Kuchuluka kwawo kumakhala kofanana ndipo zomwe zimayambitsa zimadziwika (kukwera masitepe mwachitsanzo). Mtundu uwu wa angina, womwe ukhoza kuyambika chifukwa cha kupsinjika maganizo kapena kuzizira, nthawi zambiri umayamba chifukwa cha matenda aakulu a mitsempha ya mitsempha.

M'malo mwake, ndi angina pectoris osakhazikika, zowawazo zimawonekera mwadzidzidzi, popanda chizindikiro. Zowawa zomwe zimachitika zimakhala zamphamvu mosiyanasiyana. Mtundu uwu wa angina umayamba chifukwa cha matenda opweteka kwambiri a mitsempha ya m'mitsempha ndipo samasulidwa ndi kupuma kapena ndi mankhwala omwe amamwa nthawi zambiri (pamene chithandizo chayamba kale).

Nthawi zina, angina wokhazikika amatha kukulirakulira komanso kusakhazikika. Ululu umakhala wochulukirachulukira, wamphamvu komanso umawonekera panthawi yolimbitsa thupi, mwachitsanzo. Kapena ululu umayankha mocheperapo chithandizo chamankhwala. Okhudzidwa ndi izi kusandukakuchoka ku khama angina, kuti angina pa mpumulo, ndiyeno, nthawi zina, kwa myocardial infarction.

matenda

Kuti atsimikizire angina, dokotala, atatha kutchula zoopsa za munthu amene akutsatiridwa, angapereke mankhwala a electrocardiogram ndi kuyezetsa magazi. Adzafuna kufotokoza chiyambi cha ululu. Pachifukwa ichi, echocardiography ndi kuyesa kupsinjika kungakhale kofunikira, musanapange x-ray ya mitsempha yamtima (coronary angiography).

Mavuto

Ululu woyambitsidwa ndi angina pectoris ukhoza kusokoneza ntchito zina za tsiku ndi tsiku ndipo zimafuna kupuma. Koma vuto lalikulu kwambiri ndiloti matenda a mtima kapena myocardial infarction, ndi chiopsezo cha imfa yadzidzidzi. Pachifukwa ichi, mtsempha wa mtima, mitsempha yamagazi, sichimangokhala yopapatiza monga mu angina pectoris, imatsekedwa kwathunthu. Ndipo ngoziyi iyenera kuganiziridwa. Chifukwa chake ndikofunikira kuyang'anira zachipatala kuyambira pachimake cha ululu woyamba.

Zimayambitsa

Angina pectoris amayamba chifukwa cha kuchepa kwa oxygen kwa minofu ya mtima, yomwe nthawi zambiri imayamba chifukwa cha kuchepa kwa mitsempha yamagazi. Kuchepa kumeneku m'mitsempha yama coronary kumachitika ndiatherosclerosis. Atheroma plaques (opangidwa makamaka ndi mafuta) pang'onopang'ono amapanga pakhoma la ziwiya ndipo pang'onopang'ono amalepheretsa kuti magazi aziyenda bwino.

Matenda ena amtima monga kuvulala kwa valve ya mtima kapena a cardiomyopathy kungayambitsenso angina.

Zizindikirozi nthawi zambiri zimachitika pamitsempha yamtima yomwe ilinso ndi atheroma. Angina ya Prinzmetaldo imatha kuchiritsidwa mwachangu chifukwa imakupatsirani chiopsezo chachikulu cha matenda a mtima.
