Umthambo weCoronary spasm

Imithambo yegazi ihambisa igazi kunye neoksijini entliziyweni. I-coronary artery spasm yinto emfutshane, ecothayo ngesiquphe yenye yezi mithambo.

I-spasm ihlala ivela kwimithambo yegazi engakhange iqine ngenxa yokwakhiwa kweplate. Nangona kunjalo, inokwenzeka nakwimithambo ene-plaque buildup.

Ezi spasms zibangelwa kukuxinana kwezihlunu kudonga lweartery. Zidla ngokuvela kwindawo enye yomthambo. Umthambo wecoronary unokubonakala uqhelekile ngexesha lovavanyo, kodwa awusebenzi ngesiqhelo ngamanye amaxesha.

Phantse iipesenti ezi-2 zabantu abane-angina (iintlungu zesifuba noxinzelelo) banesifo semithambo.

I-coronary artery spasm yenzeka kakhulu kubantu abatshayayo okanye abane-cholesterol ephezulu okanye uxinzelelo lwegazi. Inokwenzeka ngaphandle kwesizathu, okanye inokubangelwa ngu:

• Ukurhoxiswa kotywala
• Uxinzelelo lweemvakalelo
• Ukubonakaliswa kubanda
• Amayeza abangela ukunciphisa imithambo yegazi (vasoconstriction)
• Iziyobisi ezikhuthazayo, ezinje ngeamphetamines kunye necocaine

Ukusetyenziswa kwecocoaine kunye nokutshaya icuba kunokubangela ukuphazamiseka okukhulu kwemithambo. Oku kubangela ukuba intliziyo isebenze nzima. Kubantu abaninzi, i-coronary artery spasm inokwenzeka ngaphandle kwayo nayiphi na eminye imingcipheko yentliziyo (njengokutshaya, isifo seswekile, uxinzelelo lwegazi kunye ne-cholesterol ephezulu).

Ispasm "sinokuthula" (ngaphandle kweempawu) okanye sinokubangela iintlungu esifubeni okanye kwi-angina. Ukuba i-spasm ihlala ixesha elide ngokwaneleyo, inokubangela nesifo sentliziyo.

Uphawu oluphambili luhlobo lweentlungu zesifuba ezibizwa ngokuba yi-angina Le ntlungu ihlala iviwa phantsi kwesifuba sesifuba (sternum) okanye icala lasekhohlo lesifuba. Intlungu ichazwa njenge:

• Ukunqanda
• Ukutyunyuzwa
• Uxinzelelo
• Ukucwina
• Ukuqina

Idla ngokuba qatha kakhulu. Intlungu inokusasazeka entanyeni, emhlathini, egxalabeni, okanye engalweni.

Intlungu ye-coronary artery spasm:

• Amaxesha amaninzi kwenzeka ekuphumleni
• Kungenzeka ngexesha elifanayo ngosuku ngalunye, ngokuqhelekileyo phakathi kobusuku kunye no-8: 00 ekuseni
• Ihlala ukusuka kwimizuzu emi-5 ukuya kwengama-30

Umntu usenokulahleka.

Ngokungafaniyo ne-angina ebangelwa kukuqina kwemithambo ye-coronary, iintlungu zesifuba kunye nokuphefumla kancinci ngenxa ye-coronary artery spasm zihlala zingekho xa uhamba okanye uzilolonga.

Uvavanyo lokufumanisa isifo se-coronary spasm sinokubandakanya:

• I-Coronary angiography
• ECG
• Echocardiography

Injongo yonyango kukulawula iintlungu zesifuba kunye nokukhusela isifo sentliziyo. Iyeza elibizwa ngokuba yi-nitroglycerin (NTG) linokuthomalalisa isiqabu sentlungu.

Umboneleli wakho wezempilo unokuyalela amanye amayeza ukuthintela iintlungu zesifuba.Unokufuna uhlobo lweyeza elibizwa ngokuba yi-calcium channel blocker okanye i-nitrate esebenza ixesha elide.

I-Beta-blockers lolunye uhlobo lwamayeza olusetyenziswa kunye nezinye iingxaki zomthambo. Nangona kunjalo, ii-beta-blockers zinokuyenza le ngxaki ibe mandundu. Zifanele zisetyenziswe ngononophelo.

Ukuba unale meko, kuya kufuneka uphephe izinto ezibangela umthambo. Oku kubandakanya ukubhencwa kubanda, ukusebenzisa icocaine, ukutshaya icuba, kunye neemeko zoxinzelelo oluphezulu.

I-Coronary artery spasm yimeko yexesha elide (engapheliyo). Nangona kunjalo, unyango luhlala lunceda ukulawula iimpawu.

Ukuphazamiseka kunokuba ngumqondiso wokuba unobungozi obukhulu bokuhlaselwa yintliziyo okanye ukubetha kwentliziyo engavumelekanga. Imbonakalo ihlala ilungile ukuba ulandela unyango lwakho, iingcebiso zomboneleli wakho, kwaye uphephe izinto ezithile ezibangela.

Iingxaki zinokubandakanya:

• Isingqi esingaqhelekanga senhliziyo, esinokubangela ukubanjwa kwentliziyo kunye nokufa ngesiquphe
• Ukuhlaselwa yintliziyo

Ngokukhawuleza fowunela inombolo yongxamiseko yendawo yakho (enje nge-911) okanye uye kwigumbi likaxakeka esibhedlele ukuba unembali ye-angina kwaye ukutyumza okanye ukucofa iintlungu zesifuba akukhutshwa yi-nitroglycerin. Intlungu inokubangelwa kukuhlaselwa yintliziyo. Ukuphumla kunye ne-nitroglycerin kuhlala kungayiphelisi ngokupheleleyo intlungu yesifo sentliziyo.

Isifo sentliziyo yimeko engxamisekileyo yezonyango. Ukuba unempawu zesifo sentliziyo, funa uncedo lwezonyango kwangoko.

Thatha amanyathelo ukunciphisa umngcipheko wokuba nesifo sentliziyo. Oku kubandakanya ukungatshayi, ukutya ukutya okunamafutha asezantsi, kunye nokwandisa umthambo.
