Ukutshaya kunempembelelo enkulu kuxinzelelo lwegazi. Emva kokutshaya i-cigarette, izinga lentliziyo yezigulane ezinomfutho wegazi ophezulu liya kunyuka malunga namaxesha angama-5-20 ngomzuzu, kwaye uxinzelelo lwegazi lwe-systolic luya kunyuka malunga ne-10-25mmHg. Ixesha elide kunye nokutshaya kakhulu, oko kukuthi, ukutshaya i-cigarettes engama-30-40 ngosuku, kunokubangela ukunyanzeliswa okuqhubekayo kwemithambo emincinci.
Ukutshaya kubonakala ngokukodwa kuxinzelelo lwegazi lomntu ebusuku, kwaye ukutshaya ixesha elide kuya kwandisa kakhulu uxinzelelo lwegazi ebusuku. Uxinzelelo lwegazi oluphakamileyo ebusuku luya kubangela i-hypertrophy ye-ventricular yasekhohlo, ngoko ke ukutshaya akuchaphazeli nje uxinzelelo lwegazi kodwa kukhokelela kwiingxaki zentliziyo. Kutheni ukutshaya kunyusa uxinzelelo lwegazi? Oku kungenxa yokuba icuba linezinto ezininzi eziyingozi, njengenikotini. Inikotini inokuvuselela imithambo-luvo esembindini kunye nemithambo-luvo enovelwano, kwaye kwakhona ivuselele i-adrenal gland ukuba ikhuphe isixa esikhulu se-catecholamine, esinokukhawulezisa ukubetha kwentliziyo, kuthintele imithambo yegazi, kunye nokwandisa uxinzelelo lwegazi.
Uphononongo lwabantu abaphantse babe ngama-5000 abaye balandelwa kwiminyaka eyi-14.5 bafumanisa ukuba uxinzelelo lwegazi lwabantu abaneminyaka ephakathi kunye nabantu abadala abaye batshaya ixesha elide kwaye batshaya babeyi-1.15 kunye ne-1.08 ngamaxesha aphezulu kunabantu abangabhemi abaphakathi kunye nabantu abadala, ngokulandelanayo. Ngokuqinisekileyo, lo mlinganiso awukho phezulu kakhulu, ngoko olu phononongo lukholelwa ukuba ukutshaya kungumngcipheko ophakathi koxinzelelo lwegazi.
Ukongeza, kukwakho idatha ebonisa ukuba abaguli abanoxinzelelo lwegazi abanomkhwa wokutshaya, ngenxa yokuncitshiswa kobuntununtunu kumachiza e-antihypertensive, unyango lwe-antihypertensive alululanga ukufumana ukusebenza okwanelisayo, kwaye kufuneka banyuse idosi.
