E-United States, ucwaningo olusha olushicilelwe yi-American Heart Association lugqamisa iqiniso lokuthi ukusetshenziswa kukagwayi we-e-cigarette oqukethe i-nicotine ngumuntu ongabhemi kungashintsha izinga le-adrenaline elihloselwe inhliziyo.
EKHUPHUKILE AMAZINGA E-ADRENALINE KWABANGENZI ABABHAYIYO?
Okokuqala, kubalulekile ukucacisa ukuthi i-American Heart Association ayiyona i-pro-vaping ngempela. Eziningana ukukhishwa kwezindaba ngokumelene nogwayi we-elekthronikhi sezivele zihlongozwa ngu inhlangano.
Ngokocwaningo olusha olushicilelwe kujenali “ I-American Heart Association“, abangabhemi abanempilo bangase babe namazinga anyukile e-adrenaline enhliziyweni ngemva kokufutha i-nicotine e-liquid. Ngempela, i-adrenaline ihanjiswa ngegazi, isebenza ngqo enhliziyweni. Ukushaya kwenhliziyo yakhe kuyenyuka kodwa lokhu kwesinye isikhathi kungaze kubangele i-tachycardia ngoba inhliziyo iyagijima.
Holly R. Middlekauff, umbhali ohamba phambili ocwaningweni kanye noprofesa wezokwelapha (inhliziyo) e-David Geffen School of Medicine e-UCLA uthi, " Nakuba ama-e-cigarettes ngokuvamile ehlinzeka ngama-carcinogens ambalwa kunalawo abonwa entuthuni kagwayi, aphinde anikeze i-nicotine. Abaningi bakholelwa ukuthi itiyela hhayi i-nicotine ebangela ukwanda kwengozi yomdlavuza nesifo senhliziyo »
Ukuze bazibeke ekungabibikho kwengozi okungaba khona kwe-vaping, uSolwazi Middlekauff nethimba lakhe basebenzisa indlela ebizwa ngokuthi "ukuhlukahluka kwesilinganiso senhliziyo" etholwe ekurekhodweni kwesikhathi eside nokungahlaseli kokushaya kwenhliziyo. Ukwehluka kwezinga lokushaya kwenhliziyo kubalwa kusukela kuzinga lokuhlukahluka ngesikhathi phakathi kokushaya kwenhliziyo. Lokhu kuhlukahluka kungabonisa inani le-adrenaline enhliziyweni.
Lokhu kuhlolwa kokushintshashintsha kwenhliziyo kuye kwasetshenziswa kwezinye izifundo ukuxhumanisa i-adrenaline eyandayo enhliziyweni nengozi yenhliziyo eyengeziwe.
Ngokusho kukaSolwazi Middlekauff, lolu wucwaningo lokuqala oluhlukanisa i-nicotine kwezinye izingxenye ukuze kubhekwe umthelela ugwayi we-elekthronikhi ongaba nawo enhliziyweni yomuntu.” Kulolu cwaningo, kwakukhona abantu abadala abangu-33 abaphile kahle ababengabhemi noma babengabhemi.
Ngezinsuku ezihlukene, umhlanganyeli ngamunye wasebenzisa i-e-cigarette ene-nicotine, i-e-cigarette engenayo i-nicotine, noma idivayisi yokulingisa. Abacwaningi balinganise umsebenzi we-adrenaline yenhliziyo ngokuhlola ukuguquguquka kwesilinganiso senhliziyo nokucindezeleka okwenziwe nge-oxidative kumasampula egazi ngokuhlola i-plasma enzyme paroxonase (PON1).
INICOTINE EHHOLILEYO AYILIMALI FUTHI AYIPHEPHILE!
Ukuchayeka komhwamuko ku-nicotine kubangele amazinga engeziwe e-adrenaline enhliziyweni, njengoba kuboniswa ukuhlukahluka okungavamile kwesilinganiso senhliziyo.
Ukucindezeleka okwenziwe nge-oxidative, okwandisa ingozi ye-atherosclerosis nesifo senhliziyo, akubonisi ushintsho ngemva kokuchayeka ku-e-cigarettes ene-nicotine nangaphandle kwayo. KuProfesa Middlekauff, uma inani labamaka abafundelwe ukucindezeleka kwe-oxidative belincane, ezinye izifundo zokuqinisekisa zizodingeka.
« Nakuba kuqinisekisa ukuthi izinhlanganisela ezingezona i-nicotinic azinawo umthelela osobala emazingeni e-adrenaline enhliziyweni, le miphumela yenza ukungabaza ngomqondo wokuthi i-nicotine ehogeliwe ayinabungozi noma iphephile. Ucwaningo lwethu lubonise ukuthi ukusetshenziswa kwe-e-cigarette okunamandla ne-nicotine kwandisa amazinga e-adrenaline enhliziyo. Njengoba izinga le-adrenaline yenhliziyo lihlotshaniswa nengozi eyengeziwe ezigulini eziye zazi isifo senhliziyo ngisho nasezigulini ezingenaso isifo senhliziyo esaziwayo, ngicabanga ukuthi lokhu kuyakhathaza kakhulu futhi kungaba yinto efiselekayo ukudikibalisa abangabhemi ukusebenzisa ugwayi we-elekthronikhi.".
Ngokusho kwakhe, ugwayi we-elekthronikhi, njengayo yonke imikhiqizo kagwayi, ubeka izingozi. Ngokuphathelene nezifundo zesikhathi esizayo, kufanele zibheke eduze kakhulu ekucindezelekeni kwe-oxidative ngesikhathi sokusetshenziswa kwe-e-cigarette usebenzisa inombolo enkulu yezimpawu zenhliziyo ezinabantu abaningi.
