Iqela lamazwe aphesheya laqhuba izifundo ezininzi zenzala kwizifo zentliziyo. Kwavela, abantu abaneqela elithile legazi banomngcipheko omkhulu wesifo sentliziyo.
Izifo zentliziyo zihlala kwenye yeendawo ezikhokelayo phakathi kwezizathu zokulaliswa esibhedlele kunye neziphumo ezibulalayo kwihlabathi liphela. Ukonakaliswa kwenqanaba lezempilo kukhokelela kwimikhwa emibi kunye neendlela zokuphila kunye ne-ecology, uxinzelelo, kunye nezinye iinyani. Kukho uluhlu lwezizathu zokugula kwentliziyo kunye namaqela egazi lemvelo. Isigqibo esinjalo senziwa ziingcali kwiqela labaphandi ezingeniswe ngabasebenzi bezonyango ze-European zaseYurophu.
Kwithuba lokufunda, iingcali zihlalutya imbali yezifo ezimalunga nama-400 abaguli. Uvavanyo lubandakanya abantu bamacandelo ahlukeneyo obudala bobabini babelana ngesondo. Ngokweziphumo zomsebenzi, baxoxa ukuba abantu abaneqela lokuqala legazi babonakale kwisifo sentliziyo. Banemigangatho ebalulekileyo ye-Cardioysms, ayikabi-mali ngeipesenti ezisi-8 ngokuthelekiswa nabanini bamanye amaqela. Nangona kunjalo, uluhlu kunye nobukho bokusilela kwentliziyo kwezigulana zezona ziguli zezona zininzi.
Abantu abaneqela lesithathu nelise lesibini lihlala linengxaki ye-vein enzulu. Zikhokelela kwiqela elinomngcipheko we-rombosis eqhubela phambili kwimithambo yemiphunga. Kwangelo xesha, ukugqobhoza kwegazi kuqhuma ukuhamba kwegazi kwimilenze, apho bebunjwe khona, ukuya kwinkqubo yokuphefumla. Kwimeko yokuphambuka, iyakwazi ukuvimba ukuhamba kwegazi entliziyweni. Amaqela okwesibini neyesithathu akwahluke ngepesenti ezi-3 ngokubhekisele kwingozi yokuqala yokwandisa uxinzelelo lwegazi.
Idatha efunyenwe ngoogqirha iya kunceda ukuphucula ezona ndlela zilungileyo zothintelo kunye nokunyanga izifo zentliziyo kunye nemithambo yegazi. Iziphumo ziya kusetyenziswa kwaye ziyiqonde ngakumbi inkqubo yokwenziwa kweetroms. Ukuqwalaselwa eyongezelelweyo kuya kunika umfanekiso ocacileyo wokuchonga amanqanaba omngcipheko kunye nokuphuhliswa kweziyobisi kunye neendlela zonyango, kuthathelwa ingqalelo iimpawu zemfuza.
