Ukuphepha Iingxaki Eziqhelekileyo Zokuxinzelelo Kwegazi Eliphezulu

Umonakalo wezintso kunye nokuhlaselwa kwentliziyo ziphakathi kweempembelelo ezinkulu ze-hyptension

Uxinzelelo lwegazi oluphezulu luhambelana neengxaki ezininzi ezinokuba yingozi. Ukusuka kwintlungu yokulimala kwintliziyo, ukuphepha iziphumo ezingapheliyo zengcinezelo kuthetha ukusebenza ukulawula uxinzelelo lwegazi. Funda iimeko eziqhelekileyo ezidlulileyo kwixesha elide loxinzelelo lwegazi kunye nendlela yokuziphepha.

Ukuhlaselwa yintliziyo

Ukuhlaselwa yintliziyo kubangelwa ukuphazamiseka kwegazi kwiimitha ze-coronary, ezinika intliziyo yesisu kunye ne-oxygen kunye nezondlo. Uxinzelelo oluphezulu lwegazi luphakamisa umngcipheko wokuhlaselwa kwentliziyo kwaye landisa amathuba okuba intlungu yesifo xa kwenzeka, iya kuba nzima. Lo mngcipheko okhulayo kukuba uxinzelelo oluphezulu lwegazi luye lugxininise intliziyo-lwenza lusebenze nzima kunokuba luqhelekileyo-kwaye lufaka isandla ekuvelweni kwemibhobho engaphazamisa ukuhamba kwegazi.

Stroke

Izibetho, ezifana nokuhlaselwa kwentliziyo, kubangelwa ukuphazamiseka kwegazi. Kwimeko yokuphazamiseka, ukuphazamiseka kusengqondweni. Xa ukuphuma kwegazi kwingqondo kuphazamisekile, iindawo zengqondo kuxhomekeke kwigazi elimele. Ngamanye amaxesha ukubetha, njengokuhlaselwa kwintliziyo, kwenzeka ngenxa yokuba umkhumbi wegazi uvalwe kwaye igazi alikwazi ukuhamba ngaphaya kwelokuvimba. Kwezinye iimeko, isitya esincinci segazi sinokuphuka, kwaye ukunciphisa kuncitshiswa ngenxa yokuba igazi liphuma emkhunjini. Uxinzelelo oluphezulu lwegazi lwandisa umngcipheko wezo zombini iziganeko.

Ukulimala kweentso

Iingongoma zibalulekileyo zexesha elide lomzimba wegazi. Ziyakhathalela nemiphumo yokunyuka kwengcinezelo yegazi, eyonakalisa izihlunu ezichukumisayo ezijongene nokulawula umlinganiselo womzimbeni emzimbeni. Umonakalo wezinso kunye nokunyanga kwengcinezelo yegazi yinkingi yokuziqinisa, kunye nokunyanga kwengcinezelo yegazi eyenza umonakalo obangela ukunyuka kwengcinezelo yegazi. Umonakalo wezintso ngenye yeengxaki ezinzima kakhulu ezide zengcinezelo yegazi eliphezulu.

Fibrillation yeArivri

I-fibrillation ye-Atrial ngumhlobo we- arrhythmia okanye isifo senhliziyo esingalungelekanga. Nangona i-fibrillation ye-agrifu ibangela utshintsho ekusebenzeni kakuhle kwenhliziyo - echaphazela ukuhamba kwegazi kuwo wonke umzimba - iguqula ukuhamba kwegazi ngaphakathi kwintliziyo ngokwayo kwaye inike iimeko zeemeko ezinokubangela ukubunjwa kwamacandelo amancinci egazi. Lawa maqhekeza egazi aze aphephe emzimbeni, apho angabanjwa khona emitanjeni yegazi enika ingqondo. Oku kukhokelela ekuphazamiseni ukuhamba kwegazi kwisitya esivinjiweyo, esinokubangela ukubetha. Uxinzelelo lwegazi oluphezulu luguqula ukutshintsha kweengcambu zeentliziyo kwaye kunokubangela ukuba intliziyo ikhule kwaye ityululwe, iyakhuthaza ukuphuculwa kwefayilifayili ye-atrial.

KwiCoronary Artery Disease

I-coronary isifo somgubo ibhekisela ekubunjweni kwemibhobho emithanjeni yegazi ezondla intliziyo. Ezi zithintelo zenziwe ngamafutha, i-cholesterol kunye nohlobo lweselingo olubizwa ngokuba yi-macrophage. Nangona ikhonkco phakathi kwegazi eliphezulu kunye ne-coronary artery disease isaphenywa, ubungqina bubonisa ukuba ukuphakama okungapheliyo kwingcinezelo yegazi kubangela umonakalo nokuvuvukala kwiindonga zemithambo yegazi. Lo monakalo kunye nokuvuvukala kukutsala i- macrophages leyo, ngokukhawuleza, inikezela indawo "enamathele" apho amafutha kunye ne-cholesterol banakho ukunamathela, okukhokelela ekuphuhlisweni kwezicwangciso. Izibhengezo ezibangelwa zizifo ze-coronary disease ziyintloko ebangela ukuhlaselwa yintliziyo.
