Ngaba wakha wamiselwa amayeza oxinzelelo lwegazi oluphezulu okanye ezinye iingxaki zentliziyo ngugqirha? Mhlawumbi ukhe weva "ngee-blood vessel dilators." La mayeza adla ngokubizwa ngokuba zii-vasodilators. Ngoko ke namhlanje, masithethe ngawo ngokulula, ngokungathi uthetha nomhlobo.
Zithini ezi vasodilators?
Ngamafutshane, ii-vasodilators ngamayeza avula kwaye andise imithambo yegazi yakho . Cinga ngombhobho wamanzi. Ukuba umbhobho uvaliwe okanye unciphile, amanzi ahamba ngokukhawuleza kakhulu kwaye enoxinzelelo olukhulu. Kodwa ukuba umbhobho ubanzi ngokwaneleyo, amanzi ahamba lula kakhulu kwaye enoxinzelelo oluncinci. Yile ndlela la mayeza asebenza ngayo emizimbeni yethu.
Kukho iintlobo ezimbini eziphambili zemithambo yegazi emzimbeni wethu.
- Imithambo: Buyisela igazi elivela emzimbeni entliziyweni.
- Imithambo yegazi: Ithwala igazi lisuka entliziyweni liye kuzo zonke iindawo zomzimba.
IiVasodilators ngamayeza aphumza izihlunu ezikwiindonga zale mithambo kunye nemithambo yegazi, ethintela ukuba zingaqini okanye zinciphe. Le nkqubo ibizwa ngokuba yivasodilation .
Zisebenza njani ezi ziyobisi?
Kukho iintlobo ezahlukeneyo zamayeza e-vasodilator, ngalinye lisebenza ngendlela eyahlukileyo kancinci.
Amanye amayeza, abizwa ngokuba yi-Direct Vasodilators , asebenza ngokuthe ngqo kwiiseli zemisipha ezindongeni zemithambo yegazi, eziphumza. Ngenxa yokuba zisebenza ngokukhawuleza, ngamanye amaxesha zinokuba nomngcipheko okhulayo weziphumo ebezingalindelekanga. Oogqirha bayawasebenzisa la mayeza xa ezinye iindlela zonyango zingaphumelelanga ukulawula iimpawu.
Ezinye iintlobo zamayeza zisebenza ngendlela eyahlukileyo kancinci. Zilawula iikhemikhali ezandisa okanye ezinciphisa imithambo yegazi yethu.
Iintlobo eziphambili ze-vasodilators
Ukuze sikuqonde ngcono oku, makhe sijonge olu hlobo lwamayeza kwitheyibhile.
| Uhlobo lweyeza | Indlela esebenza ngayo (ngamagama alula) |
|---|---|
| Izithinteli ze-ACE (izithinteli ze-Angiotensin-Converting Enzyme) | Iyanciphisa ubungakanani be-angiotensin, ikhemikhali emzimbeni ethintela imithambo yegazi. |
| Ii-ARB (ii-Angiotensin Receptor Blockers) | I-Angiotensin ithintela le khemikhali ukuba inganamatheli eludongeni lwemithambo yegazi, nto leyo ebangela ukuba imithambo yegazi ikhule. |
| Ii-Calcium Channel Blockers (ii-CCB) | Iyayithintela i-calcium, efunekayo ukuthintela imithambo yegazi, ukuba ingangeni eludongeni lwemithambo yegazi. |
| IiNitrates | Ezi ziguqulwa zibe yigesi ebizwa ngokuba yi-nitrous oxide emzimbeni kwaye zandise imithambo yegazi. |
Ziziphi iimeko ezisetyenziselwa i-vasodilators?
Oogqirha banika la mayeza ukunyanga iimeko ezahlukeneyo ezinxulumene nokujikeleza kwegazi. Ezinye zazo ziquka:
- Uxinzelelo lwegazi: "Uxinzelelo" esilwaziyo sonke.
- I-Angina: Intlungu yesifuba ebangelwa kukuncipha kokuhamba kwegazi entliziyweni.
- Ukusilela kwentliziyo okuxineneyo (CHF): Intliziyo ayikwazi ukupompa igazi elaneleyo emzimbeni.
- Uxinzelelo lwegazi oluphezulu lwemiphunga: Uxinzelelo oluphezulu kwimithambo yegazi yemiphunga.
- I-Preeclampsia: Uxinzelelo lwegazi oluphezulu ngexesha lokukhulelwa.
Zithini iziphumo ebezingalindelekanga zale mithi?
Njengayo nayiphi na iyeza, ezi vasodilators zinokubangela ezinye iziphumo ebezingalindelekanga. Nangona kunjalo, ayinguye wonke umntu ozifumanayo. Kwakhona, iziphumo ebezingalindelekanga zinokuhluka kumntu nomntu.
Okubaluleke kakhulu: Ukuba ufumana naziphi na iziphumo ebezingalindelekanga, kubaluleke kakhulu ukuthetha nogqirha wakho ngaphandle kokuyeka amayeza ngequbuliso .
Ezinye zezona ziphumo bezingalindelekanga zixhaphakileyo zezi:
- Isiyezi
- Intloko ebuhlungu
- Intliziyo ebuhlungu okanye i-tachycardia
- Ukudinwa
- Ukudumba kwemilenze ngenxa yokugcinwa kwamanzi emzimbeni (i-edema)
- Isicaphucaphu nokuhlanza
- Intlungu yamalungu
- Abanye abantu abasebenzisa i-ACE inhibitors banokuba nokukhwehlela okomileyo .
Ngamanye amaxesha, kunokunikwa elinye iyeza ukulawula isiphumo esingesihle. Umzekelo, ukuba i-vasodilator ibangela ukugcinwa kolwelo (i-edema), iyeza elibizwa ngokuba yi-diuretic linokunikwa ukunceda ukususa ulwelo olongezelelweyo emzimbeni.
Ngaba kunokwenzeka ukwandisa imithambo yegazi ngokwendalo ngaphandle kwamayeza?
Kakade kunokwenzeka. Kukho amaxesha apho imizimba yethu ikhula ngokwendalo imithambo yegazi.
- Ukuzilolonga: Xa sizilolonga, izihlunu zethu zifuna ioksijini kunye nezondlo ezingaphezulu, ukuze imithambo yegazi ivuleke.
- Iikhemikhali zendalo emzimbeni: Imizimba yethu ivelisa iikhemikhali ezifana ne-nitric oxide ezandisa imithambo yegazi.
- Utywala: Xa abanye abantu besela utywala, ulusu lwabo luba bomvu kwaye bazive beshushu kuba imithambo yegazi iyavuleka.
Ukongeza, kuthiwa ukutya okuthile kunye nezongezo ziyanceda koku, njengegalikhi, ikokho, kunye neCoenzyme Q10.
Kodwa khumbula! Ngaphambi kokuba usebenzise nasiphi na isongezelelo, ngokuqinisekileyo kufuneka ubuze ugqirha wakho . Ezinye izongezo zinokusebenzisana namayeza owasebenzisayo.
Izinto ekufuneka uzilumkele xa usebenzisa amayeza
Ukuba uthatha amayeza okunciphisa imithambo yegazi (vasodilators), kunokubakho iingxaki ngokutya okuthile kunye namanye amayeza. Kubaluleke kakhulu ukuxelela ugqirha wakho ngawo onke amayeza owasebenzisayo, kuquka neevithamini.
Umzekelo:
- Abantu abasebenzisa ii-CCB (Calcium Channel Blockers) kufuneka baphephe ukusela ijusi yegrapefruit.
- Abantu abasebenzisa i-nitrate kufuneka baphephe ukusebenzisa amayeza afana ne-sildenafil (Viagra®), kuba ukuthatha ezi zinto zombini kunye kunokubangela uxinzelelo lwegazi oluphantsi ngendlela eyingozi.
Ugqirha wakho uza kukuchazela oku ngokweenkcukacha.
Umyalezo Wokuya Ekhaya
- IiVasodilators luhlobo lwamayeza andisa imithambo yegazi ukunyanga uxinzelelo lwegazi oluphezulu kunye nezifo zentliziyo.
- Sela amayeza akho kanye njengoko ugqirha wakho ekuyalele, ngexesha elifanelekileyo, nangedosi efanelekileyo. Ungaze uyeke ukuwasela amayeza akho wedwa.
- Qiniseka ukuba uxelela ugqirha wakho ngamanye amayeza, iivithamini, okanye izongezo ozisebenzisayo.
- Ukuba ufumana naziphi na iziphumo ebezingalindelekanga emva kokusela amayeza, thetha nogqirha wakho ngaloo nto.
- Ngaphandle kwamayeza, ukugcina indlela yokuphila enempilo (ukutya okunempilo, ukuzilolonga, kunye nokuphepha ukutshaya) kubaluleke kakhulu kwimpilo yentliziyo yakho.
