<prompt> Fingqa isihloko: Ucwaningo luthole ukuthi izisulu zokuhlaselwa yisifo senhliziyo zingalulama kahle uma zibheka izinto ezinhle ekuphileni. Ucwaningo luthole ukuthi izisulu zokuhlaselwa yisifo senhliziyo zingalulama kahle uma zibheka izinto ezinhle ekuphileni. Abantu abangenathemba ababubulayo ngokuphila babenamathuba aphindwe kabili okuhlaselwa esinye isifo senhliziyo, okudinga ukuhlinzwa noma ngisho nokufa, uma beqhathaniswa neziguli ezijabulayo. Yilokho okushiwo iqembu lososayensi e-University College London elachitha iminyaka emine lihlola isimo sengqondo seziguli ezingu-369 ezafakwa esibhedlela ngenxa ye-angina engazinzile nokuhlaselwa yisifo senhliziyo. Nakuba kwaziwa kabanzi ukuthi ukuba nethemba kuhlotshaniswa nempilo yenhliziyo engcono, lokhu kuwukucwaninga kokuqala kokubheka umthelela wesimo sengqondo sesiguli ngemva kokuhlaselwa yisifo senhliziyo. Leli qembu lathi okutholakele kwalo kungase kuhlotshaniswe nemiphumela engokomzimba nengokwengqondo yokuba nethemba, njengokubhema nokudla ukudla okunempilo. Sekuyisikhathi eside kwaziwa ukuthi ukubhema kuyimbangela eyinhloko yokuhlaselwa yisifo senhliziyo ne-angina, njengoba kulinganiselwa ukuthi abantu abangu-22 000 bafa unyaka ngamunye ngenxa yezifo zenhliziyo nemithambo yegazi ezihlobene nokubhema. Lolu cwaningo lwabonisa ukuthi isigamu seziguli ezazinombono ongemuhle ngokubhema zazisabhema unyaka ngemva kokuya esibhedlela. Ngokuphambene, amaphesenti angu-85 ababhemayo abanethemba bawuyeka ngokuphelele lo mkhuba. Iziguli ezinesimo esihle nazo zinamathuba amaningi okuthi zisize ekululameni kwazo ngokudla izithelo nemifino eminingi ngemva kwesigameko sazo - cishe amaphesenti angu-40 azo adla amahlanu alinganiselwe ngosuku, uma kuqhathaniswa namaphesenti angu-20 kuphela alabo abanesimo esibi. Nokho, lolu cwaningo lwathola ukuthi iziguli ezinesimo sengqondo sokulindela okuhle zazingenalo ithuba lokwenza ukuvivinya umzimba okwengeziwe kunabantu abanesimo sengqondo sokulindela okubi. Umlobi oholayo walolu cwaningo, uProfesa Steptoe, wathi: Ucwaningo lwethu lubonisa ukuthi abantu abanethemba banamathuba amaningi okuthatha izeluleko mayelana nezinguquko endleleni yokuphila, njengokuyeka ukubhema nokudla ngendlela enempilo lokhu kuholela emiphumeleni engcono ngemva kokuba isiguli sihlushwa i-angina engazinzile noma ukuhlaselwa yisifo senhliziyo. E-UK, abantu abayizigidi ezingu-2.3 baphila nesifo senhliziyo, okuyimbangela eyinhloko yokuhlaselwa yisifo senhliziyo kanye nesifo sokushaqeka kwesifuba. Izinto esizitholile...  <response>: Ososayensi eUCL bachitha iminyaka emine befunda isimo sengqondo seziguli zenhliziyo. Kuyaziwa kabanzi ukuthi ukuba nethemba kuhlobene nempilo enhle yenhliziyo. Lolu ucwaningo lokuqala olubheka umthelela wesimo sengqondo sesiguli ngemva kokuhlaselwa yisifo senhliziyo. Ithimba lathi lokhu okutholakele kungahlotshaniswa nemiphumela engokomzimba yokuba nethemba lokuhle njengokubhema nokudla ukudla okunempilo.
