Ocwaningweni olukhulu olwenziwa kuze kube manje ukuze kuqondwe ubudlelwano phakathi kokujwayela ukuvivinya umzimba kanye nokuqina komzimba, abacwaningi abavela eBoston University School of Medicine (BUSM) bathole ukuthi isikhathi esiphezulu esichithwa ukuzivocavoca (ukuzivocavoca umzimba okunamandla) kanye nokulinganisela okuphansi. umsebenzi wezinga (izinyathelo) kanye nesikhathi esincane esichithwe unganyakazi, okuhunyushwe ekubeni ukuqina komzimba okukhulu.
“Ngokusungula ubudlelwano phakathi kwezinhlobo ezahlukene zokuzivivinya okujwayelekile kanye nezinyathelo zokuqina ezinemininingwane, sithemba ukuthi ucwaningo lwethu luzohlinzeka ngolwazi olubalulekile olungagcina lusetshenziselwe ukuthuthukisa ubungqabavu bomzimba kanye nempilo yonke kuyo yonke inkambo yokuphila,” kuchaza umbhali ohambisanayo uMatthew Nayor, MD, MPH, umsizi kaprofesa wezokwelapha e-BUSM.
Yena nethimba lakhe bafunde ababambiqhaza abangaba ngu-2,000 abavela ku-Framingham Heart Study esekelwe emphakathini abenze izivivinyo ezibanzi zokuvivinya umzimba kwenhliziyo (CPET) ukuze bathole isilinganiso “segolide” sokuqina komzimba.Izilinganiso zokufaneleka komzimba zazihlotshaniswa nedatha yomsebenzi womzimba etholwe ngama-accelerometer (idivayisi ekala imvamisa nokuqina kokunyakaza komuntu) eyayigqokwe isonto elilodwa ngesikhathi se-CPET futhi cishe eminyakeni eyisishiyagalombili ngaphambili.
Bathola ukuvivinya umzimba okuzinikele (ukuvivinya umzimba okumaphakathi-okunamandla) yikhona okusebenza kahle kakhulu ekuthuthukiseni ukuqina.Ngokuqondile, ukuzivocavoca kwakusebenza kahle izikhathi ezintathu kunokuhamba wedwa futhi izikhathi ezingaphezu kwe-14 zisebenza kahle kunokunciphisa isikhathi esichithwa uhlezi.Ukwengeza, bathole ukuthi isikhathi esiningi esichithwa uzivocavoca kanye nezinyathelo eziphakeme/usuku kungase kuqede ingxenye yemiphumela engemihle yokunganyakazi mayelana nokufaneleka komzimba.
Ngokusho kwabacwaningi, nakuba ucwaningo lwalugxile ebudlelwaneni bokusebenza ngokomzimba kanye nokufaneleka ngokuqondile (kunokuba nanoma yimiphi imiphumela ehlobene nempilo), ukuqina kunethonya elinamandla empilweni futhi kuhlotshaniswa nengozi ephansi yesifo senhliziyo, isifo sikashukela, umdlavuza kanye ukufa ngaphambi kwesikhathi.“Ngakho-ke, ukuqonda okuthuthukisiwe kwezindlela zokwenza ngcono ukuqina komzimba kulindeleke ukuthi kube nemithelela ebanzi ekuthuthukisweni kwempilo,” kusho uNayor, udokotela wezifo zenhliziyo eBoston Medical Center.
Lokhu okutholakele kuvela ku-inthanethi ku-European Heart Journal.
