Chii chinonzi angina pectoris?
Angina pectoris, inonziwo chipingo chirwere chemoyo chinokonzera kurwadziwa muchipfuva. Marwadzo aya anoonekwa kana moyo usina mweya weokisijeni zvakanaka nekuda kwekutetepa kwetsinga yemwoyo (iyo inounza ropa rine oxygen kumoyo).
Kutanga kwe angina kunogona kuenderana ne kushushikana kana kushanda nesimba. Asi zvinogona zvakare, zvakanyanya kashoma, kuitika pakuzorora.
Marwadzo anokonzerwa neangina pectoris kusimba (kunzwa kuti chipfuva chinobatwa mu mutevedzeri, tinobva tataura nezve constrictive pain), kudzipwa kana kutsva. Marwadzo aya, angave achiperekedzwa nokurova kana kuti kutadza kufema zvakanaka, kazhinji anopera mukati memaminitsi mashoma, apo vanorwara vanovata pasi kana kuti kuzorora. Mimwe mishonga (trinitrin) inogona kubatsira kuderedza.
Marwadzo kazhinji a nyevero : mwoyo unoratidza kuti hauna oxygen uye uri kurwadziwa. Angina inopedzisira yave chiratidzo chedambudziko rakakura remoyo riri kuuya, kunyanya chirwere chemoyo (MI kana myocardial infarction).
Muhupo hwe angina pectoris, ngozi kurwiswa kwemoyo, semuenzaniso, kwakakwira. Angina pectoris inogona kupedzisira iri nhanho yekutanga ye coronary artery chirwere.
Saka zvinodikanwa, nekukurumidza kana zviratidzo zvekutanga zvaonekwa, kukurumidza kutanga zororo uye kukurumidza kubvunza chiremba mukuru, ipapo chiremba wemwoyo kuti aongorore zvakakwana zvehutano. Iyo yekupedzisira ichasimbisa kuongororwa kweangina kuburikidza nekuongorora kwakasiyana-siyana kwechiremba, kuwana zvikonzero zvayo uye kupa kurapwa kana zvichidiwa.
Angina pectoris haifaniri kuregererwa. Kutanga kwemarwadzo kunofanira kutsanangurwa, zviratidzo zvinonyevera zvinozivikanwa. Kutarisira, kutarisa uye kurapa angina pectoris kunobatsira kudzivirira mamwe mamiriro emwoyo akakomba. Mukuwedzera, kana kurwadziwa kwacho kuchipera kana kuti kwakanyanyisa, zvakakosha kuonana neSAMU (15 kana 112). Munhu wacho anogona zvechokwadi kutambura kwete kubva kune angina asi kubva infarct myocardium.
Kuwanda
Angina pectoris ine ngozi zvikuru zvakajairika. Zvingave zvine chekuita ne10% yeanopfuura makumi matanhatu neshanu muFrance.
Mhando dzakasiyana dze angina pectoris
Kune marudzi akasiyana-siyana eangina, mamwe ane marwadzo anopfuura nokukurumidza, mamwe anoitika kamwe-kamwe, asingaenderani nekushungurudzika kana kuita basa remuviri. Nokudaro, mune iyo inonzi angina pectoris tsiga,marwadzo anoramba akafanana nekufamba kwenguva. Kusimba kwavo kwakangofanana uye zvinokonzeresa zvinozivikanwa (kukwira masitepisi semuenzaniso). Mhando iyi yeangina, iyo inogona kukonzerwa nekushungurudzika kana kutonhora kwekushisa, inowanzokonzerwa nechirwere chisingaperi chechirwere chetachiona.
Nenzira, kune angina pectoris Kusagadzikana, marwadzo acho anongoerekana avapo, pasina chiratidzo chinonyevera. Marwadzo anoitika ndeekusimba kwakasiyana. Mhando iyi yeangina inokonzerwa neacute coronary artery disease uye haisunungurwi nekuzorora kana nemishonga inowanzotorwa (apo kurapa kwatotanga).
Mune zvimwe zviitiko, angina yakagadzikana inogona kuwedzera uye kuva isina kugadzikana. Marwadzo anowedzera kazhinji, akasimba uye anoonekwa panguva yekushanda kwemuviri kushoma, semuenzaniso. Kana kuti kurwadziwa kunopindura zvishoma kune kurapwa kwezvinodhaka. Vanobatwa neizvi Kushandukaenda kubva pakuedza angina, kune angina pakuzorora, uye ipapo, dzimwe nguva, kune myocardial infarction.
chirwere
Kuti asimbise angina, chiremba, mushure mekunge anyora zvipingamupinyi zvemunhu ari kuteverwa, anogona kupa a electrocardiogram uye kuongororwa ropa. Achatsvaka kutsanangura kwakabva marwadzo. Nekuda kweizvi, echocardiography uye bvunzo yekushushikana inogona kudikanwa, usati waita x-ray yetsinga dzemoyo (coronary angiography).
Matambudziko
Marwadzo anokonzerwa neangina pectoris anogona kukanganisa mamwe mabasa ezuva nezuva uye anoda kuzorora. Asi chinetso chakakomba zvikurusa ndeche hosha yemwoyo kana kuti myocardial infarction, ine ngozi yokufa kamwe kamwe. Muchiitiko ichi, tsinga yemwoyo, iyo coronary artery, haisati ichingove yakatetepa sepa angina pectoris, inova yakavharwa zvachose. Uye njodzi iyi inofanirwa kuverengerwa. Nokudaro kudiwa kwekuongororwa kwechiremba kubva pakutanga kwemarwadzo ekutanga.
Zvinokonzera
Angina pectoris inokonzerwa nekushaya oxygenation yemhasuru yemwoyo, iyo pachayo inowanzokonzerwa nekuderera kwetsinga dzeropa. Uku kutetepa mutsinga dzemwoyo kunokonzerwa neatherosclerosis. Atheroma plaques (inogadzirwa zvikuru nemafuta) zvishoma nezvishoma inoumba pamadziro emidziyo uye zvishoma nezvishoma inodzivirira ropa kuti rifambe zvakanaka.
Zvimwe zvirwere zvemoyo zvakadai sekukuvara kwevhavha yemwoyo kana a cardiomyopathy inogonawo kukonzera angina.
Prinzmetal's angina. Iyi inoshamisa angina iyo isingawanzoitiki. Chokwadi, angina kurwisa kunoitika pano pasina kushanda nesimba. Izvo hazvina hukama kune plaque yeatheroma inoderedza caliber yeimwe yetsinga dzemoyo, asi kune spasm yeimwe yeaya tsinga. Iyi spasm inononoka kusvika kweropa mukati memhasuru yemoyo iyo, ichitambura nekushayikwa kweokisijeni, inoburitsa zviratidzo zvakafanana neyekare angina (marwadzo emhando imwechete). Marwadzo anowanzoitika panguva dzenguva dzose uye anodzokororwa cyclically. . Nguva mbiri dzakajairika: chikamu chechipiri chehusiku kana nguva inotevera kudya. Marwadzo anogona kutungamirira ku syncope. |
Izvi zviratidzo zvinowanzoitika pamaronary arteries anewo atheroma. Prinzmetaldo's angina inogona kurapwa nekukurumidza nekuti inokuisa panjodzi huru yekurwadziwa kwemoyo.
