Izifundo ezimbili ezintsha zokuqala ezenziwe yi-American Heart Association zibonisa ukuthi abantu abadala abasebenzisa imikhiqizo yokuphefumula kanye nezinye izinhlobo zikagwayi we-elekthronikhi njalo zibonise ukungasebenzi kahle kwemithambo yegazi nenhliziyo futhi azenzi kahle ezivivinyweni zokuhlola ukucindezeleka uma ziqhathaniswa nalabo abangasebenzisi imikhiqizo yokuphefumula noma i-e-cigarettes. abacwaningi abenze lezi zifundo ezimbili bathola ukuthi ukufutha noma ukusebenzisa i-e-cigarettes njalo Osemncane abantu abadala iminyaka emine ngokwesilinganiso bakhiqiza izinguquko ezifanayo zenhliziyo nemithambo yegazi njengalezo ezibonwa kubantu asebebheme ugwayi iminyaka engu-20.
Olokuqala kulezi zifundo ezimbili lwenziwa kusukela ngo-March 2019 kuya ku-March 2022 ngabacwaningi base-University of Wisconsin. Umgomo wocwaningo bekuwukuthola imithelela yesikhathi esifushane kagwayi we-elekthronikhi nogwayi wendabuko kubasebenzisi abavamile uma kuqhathaniswa nalabo abangayisebenzisi leyo mikhiqizo. Kubo bonke ababambiqhaza ocwaningweni abangu-164 babenesilinganiso seminyaka engu-27.4 futhi babesebenzise ugwayi we-e kuphela isilinganiso seminyaka engu-4.1.
Ngokusho kukaMathew C. Tattersall, uprofesa wezokwelapha we-University of Wisconsin School of Medicine kanye ne-Public Health kanye nomqondisi we-UW Health kaMadison we-Preventive cardiology, owayengumbhali oholayo walolu cwaningo, ababambiqhaza ocwaningweni babonisa izinga lokushaya kwenhliziyo eliyingozi, ithoni yemithambo yegazi nomfutho wegazi ngokushesha ngemva kokubhema noma ukusebenzisa umkhiqizo we-e-cigarette abawuthandayo. Lokhu okutholakele kukhombisa ukuthi abantu abavame ukusebenzisa ugwayi we-elekthronikhi noma ababhemayo banengozi embi kakhulu yokuthola izifo zenhliziyo ngemuva kokubhema noma ukufutha. Umcwaningi ukholelwa ukuthi ukubhema noma ukusebenzisa imikhiqizo yokuphefumula kwasebenza isimiso sezinzwa esizwelayo futhi lokhu kunesibopho sezinto eziyingozi ezirekhodwa ngokushesha ngemva kokuphefumula noma ukubhema kanye nemizuzu engu-90 kamuva lapho izivivinyo zokuhlolwa zenziwe.
Ucwaningo lwesibili luqhathanise izivivinyo zabahlanganyeli ababhemayo noma abangabhemi nalabo abangabhemi noma abangabhemi. Umgomo walolu cwaningo kwakuwukuhlola ukuthi iqembu ngalinye labahlanganyeli lenze kanjani izivivinyo zokuhlola ukucindezeleka eziklanyelwe ukubikezela ingozi yokuthuthukisa izifo zenhliziyo. Ucwaningo lusebenzise izivivinyo zokuhlola ingcindezi ye-treadmill ezenziwe imizuzu engama-90 ngemuva kokuthi umhlanganyeli ngamunye ebheme noma efake i-vaped eqenjini lalabo abavuma ukuthi bangababhemi abavamile noma ama-vaper. Kulabo abangabhemi futhi abangabhemi izivivinyo ezifanayo zenziwa emizuzwini engama-90 ngemuva kokuba ababambiqhaza ngamunye bephumule.
NgokukaChristina M. Hughey, umbhali oholayo wocwaningo kanye nozakwabo we-UW kwezempilo yenhliziyo nemithambo yegazi, abantu abavamise ukubhema noma ababhemayo basebenze kabi kuwo wonke amapharamitha amane uma kuqhathaniswa nalabo abangasebenzisanga imikhiqizo ye-nicotine ngisho nalapho beneminyaka yobudala, ubulili futhi. umjaho wawufakwe phakathi. Ngaphezu kwalokho, ukusebenza phakathi kwalabo ababhemayo kwakungehlukile nganoma iyiphi indlela ebalulekile. Lokhu kwenzeka nakuba labo abakhipha i-vaped babebancane kakhulu futhi babebike ukuthi bavamise njalo iminyaka embalwa ngokwesilinganiso kunalabo ababike ukuthi bayabhema.
Lezi zifundo ezimbili zokuqala zethulwe ku-2022 Scientific Sessions for American Heart Association Ebanjwe ngasekuqaleni kukaNovemba 2022. Kulindeleke ukuthi zenze isisekelo socwaningo oluqhubekayo ngomthelela wokuphefumula kanye nokubhema ezicini eziyingozi ezihlobene nesifo senhliziyo.
