Ndị Beta blockers nwere ọtụtụ ojiji na nkà mmụta ọgwụ. Otu n'ime ihe kachasị mkpa bụ ịgwọ ndị ọrịa nwere ọrịa nkwonkwo akwara (CAD) na angina.
Kedu ka ndị Beta Blockers si eme ka ndị ọrịa nweta uru?
N'ọnwa ndị nwere ọrịa angina rụrụ site na CAD, a na-ewere ndị beta blockers na ọgwụgwọ mbụ.
N'okwu angina, otu ma ọ bụ karịa akwara akwara na-egbochi site na akara ngosi atherosclerotic .
Dịka, akwara obi na-enye site na artery na-arịa ọrịa na-enweta ọbara zuru oke n'oge ezumike. Ma n'oge mmega ahụ ma ọ bụ oge nke nrụgide, nkwụchi anya nke na-egbochi ọbara ọgbụgba si na-eto eto zuru oke iji nye oxygen dị mkpa na ahụ ike obi na-arụ ọrụ, uru ahụ na-aghọkwa ihe na - edozi ahụ (agụụ maka ikuku oxygen). N'ihi ya, angina na-eme.
Ndị Beta blockers na-arụ ọrụ site na igbochi mmetụta nke adrenaline na obi. Nke a nwere isi uru abụọ dị mkpa na ndị ọrịa na angina:
- Ịkwụsị nke obi, karịsịa n'oge mmega ahụ ma ọ bụ nrụgide.
- Mbelata ike nke obi mgbagwoju anya.
Ihe abụọ ndị a na-eme ka ike obi ghara ịchọrọ ikuku, na ischemia (na angina) na-egbu oge ma ọ bụ gbochie ya.
Kedu ihe bụ Mmetụta nke Ndị Beta Blockers na Ndị Ọrịa Na-ewe Iwe?
Na ndị ọrịa na angina, ndị beta blockers na-adịkarị irè iji melite ike ma ọ bụ oge nke mmega ahụ nwere ike ịme ma ọ bụrụ na enweghi ihe na-emepụta ma ọ bụ angina.
Ndị ọrịa nwere angina nke na-ejide beta blockers na-enwekarị ọhụụ nke angina na-ahụ anya ma na-ewere nitroglycerin obere oge.
Tụkwasị na nke a, na ndị ọrịa nwere angina ndị nwere mgbapụta myocardial . (mgbu obi), ndị beta blockers bụ nanị ọgwụ mgbochi angina nke e gosipụtara iji belata ihe ize ndụ nke ịnweta infarction ọzọ myocardial.
Ọzọkwa, n'ime ndị lanarịrị infarction nke myocardial, ma ọ bụ ndị ọrịa nwere nkwarụ obi na mgbakwunye na angina siri ike, e gosipụtara ndị beta blockers iji mee ka ndụ dịkwuo mma.
Uru ndị beta blockers nyere ha mere ka ha bụrụ ọgwụ ndị mbụ ịhọrọ n'ịgwọ ndị ọrịa na CAD na stable angina.
Mmetụta dị n'akụkụ nke Beta Blockers
Akpa mmetụta nke beta blockers na-agụnye bradycardia (obere obi ọnụ), nsogbu ndị na-egbu ume na ndị nwere ụkwara ume ọkụ ma ọ bụ ọrịa na-adịghị ala ala, ike ọgwụgwụ, njọ nke mgbaàmà nke ọrịa akwara afọ , ịda mbà n'obi, na arụmọrụ erectile . E kwesịkwara izere ndị na-egbochi Beta na ndị ọrịa na angina n'ihi angina nke Prinzmetal (sparm coronary) , ebe ọ bụ na ndị a na-arịa beta blockers nwere ike ime ka ụfọdụ spasm mgbe ụfọdụ.
Ọtụtụ n'ime mmetụta ndị a nwere ike izere ndị ọrịa na angina site na iji beta blockers nke na-arụ ọrụ bụ na obi n'onwe ya, nke ahụ enweekwa ntakịrị mmetụta na arịa ọbara, ngụgụ, na usoro nkwụsị nke etiti. "Ndị na-egbochi" beta blockers bụ Tenormin (atenolol) na metoprolol (Lopressor, Toprol XL).
