EUnited States, uphando olutsha olupapashwe yi-American Heart Association lugxininisa into yokuba ukusetyenziswa kwe-e-cigarettes equkethe i-nicotine ngumntu ongabhemiyo kuya kutshintsha izinga le-adrenaline ejoliswe kwintliziyo.
UKWANDA KWAmanqanaba e-ADRENALINE KUBANTU ABANGATSHAYI?
Okokuqala, kubalulekile ukucacisa ukuba uMbutho weeNtliziyo zaseMelika ayisiyiyo ipro-vaping. Abaliqela unxibelelwano ngokuchasene necuba lombane sele zicetywe ngu umbutho.
Ngokophando olutsha olupapashwe kwijenali “ Umbutho wentliziyo yaseMelika", abantu abangatshayiyo abasempilweni banokufumana amanqanaba anyukileyo e-adrenaline entliziyweni emva kwe-nicotine e-liquid. Enyanisweni, i-adrenaline ihanjiswa ngegazi, isebenza ngokuthe ngqo entliziyweni. Ukubetha kwentliziyo yakhe kuyenyuka kodwa ngamanye amaxesha oku kunokuhamba kude kubangele i-tachycardia kuba intliziyo iyabetha.
Holly R. Middlekauff, umbhali okhokelayo kunye noprofesa weyeza (i-cardiology) kwi-David Geffen School of Medicine e-UCLA uthi, " Nangona i-e-cigarettes ngokubanzi ibonelela ngee-carcinogens ezimbalwa kunezo zibonwa kumsi wecuba, nazo zibonelela nge-nicotine. Abaninzi bakholelwa ukuba yitela kungekhona inikotini ekhokelela kumngcipheko okhulayo womhlaza kunye nesifo senhliziyo »
Ukuze bazibeke ekungabinabungozi komphumo, uNjingalwazi Middlekauff kunye neqela lakhe basebenzisa ubuchule obubizwa ngokuba "kukuguquguquka kwentliziyo" efunyenwe kurekhodisho olude nolungaphazamisiyo lokubetha kwentliziyo. Ukwahluka kwesantya sentliziyo kubalwa ukusuka kwiqondo lokuguquguquka kwixesha phakathi kokubetha kwentliziyo. Oku kuguquguquka kungabonisa inani le-adrenaline entliziyweni.
Olu vavanyo lokuguquguquka kwentliziyo lusetyenziswe kwezinye izifundo ukudibanisa i-adrenaline eyandisiweyo entliziyweni kunye nomngcipheko wentliziyo.
Ngokutsho kukaNjingalwazi Middlekauff, olu luphononongo lokuqala olwahlula i-nicotine kwamanye amacandelo ukuze kubonwe impembelelo icuba le-elektroniki elinokuba nalo entliziyweni yomntu.Kolu phononongo, bekukho abantu abadala abangama-33 abasempilweni abangazange batshaye okanye bangatshayi.
Ngeentsuku ezahlukeneyo, umthathi-nxaxheba ngamnye wasebenzisa i-e-cigarette ene-nicotine, i-e-cigarette ngaphandle kwe-nicotine, okanye isixhobo sokulinganisa. Abaphandi balinganisa umsebenzi we-cardiac adrenaline ngokuvavanya ukuguquguquka kwentliziyo kunye noxinzelelo lwe-oxidative kwiisampuli zegazi ngokuhlola i-plasma enzyme paroxonase (PON1).
INICOTINE EHAMBISWEYO AYIKHONZA INGEKHO AKUKHUSELEKANGA!
Ukutshatyalaliswa komphunga kwi-nicotine kubangele amanqanaba okwanda kwe-adrenaline entliziyweni, njengoko kubonakaliswe kukuguquguquka okungaqhelekanga kwentliziyo.
Uxinzelelo lwe-oxidative, olonyusa umngcipheko we-atherosclerosis kunye nokuhlaselwa yintliziyo, alubonisi tshintsho emva kokuvezwa kwe-e-cigarettes kunye nangaphandle kwe-nicotine. KuProfesa Middlekauff, ukuba inani labamakishi abafundelwa uxinzelelo lwe-oxidative lalincinci, ezinye izifundo zokuqinisekisa ziya kufuneka.
« Nangona kuqinisekisa ukuba i-non-nicotinic components ayinayo impembelelo ecacileyo kumanqanaba e-adrenaline entliziyweni, ezi ziphumo zenza ukuthandabuza kwingcamango yokuba i-nicotine ephefumulayo ayinabungozi okanye ikhuselekile. Uphononongo lwethu lubonise ukuba ukusetyenziswa kwe-e-cigarette ngokukhawuleza kunye ne-nicotine kwandisa amanqanaba e-cardiac adrenaline. Ekubeni inqanaba le-cardiac adrenaline lihambelana nomngcipheko okhulayo kwizigulane eziye zazi isifo senhliziyo kunye nakwizigulane ezingenasifo senhliziyo esaziwayo, ndicinga ukuba oku kuyinkxalabo enkulu kwaye kuya kuba yinto enqwenelekayo ukudimaza abangabhemi ukuba basebenzise i-cigarette ye-elektroniki.".
Ngokutsho kwakhe, i-cigarettes ye-elektroniki, njengazo zonke iimveliso zecuba, ibeka ingozi. Ngokumalunga nezifundo ezizayo, kufuneka zijonge ngakumbi uxinzelelo lwe-oxidative ngexesha lokusetyenziswa kwe-e-cigarette usebenzisa inani elikhulu labamakishi bentliziyo enabemi abaninzi.
