Kaafi vascular

kaafi Vascular dhacdaa oo ku saabsan 1-2% wadarta guud ee dadweynaha. xaalad noocan oo kale ah had iyo jeer waa natiijo ah oo ka cudur kasta. Xaaladaha intooda badan, waxay u horseeddaa cudurrada wadnaha iyo nidaamka. Kuwaas waxaa ka mid cardiomyopathy, angina, Wadnaxanuun myocardial, cilladaha wadnaha.

guuldaradii ee muruqa wadnaha ku kicin kara xadgudub sahayda dhiigga jidhka, sababtoo ah halka ay daciifaan iyo waxqabadka lagu qancin ee function shubto ay.

kaafi Vascular waxa lagu gartaa sida xaalad cudur taas oo ay jirto hoos u dhac in tonus ee muruqa siman derbiyada markabka. Tani dhirfinaya hypotension, khalkhal ku soo laabtay arooriyaha iyo qulqulka dhiigga.

kaafi Vascular sabab u lesions aasaasiga ah nooca wadnaha Ulasocto xubnaha iyo weelashii falcelin lama huraan. reaction Tani waxa lagu gartaa nooca ah magdhawga. kaafi vascular wadnaha Sayidka ba'an ku weheliyay reaction, kaas oo muujiyey in foomka of vasoconstriction jawaab u saamaynta habab pressor. Tani waxay keenaysaa in la kordhiyo iska caabin ah vascular muddo qaarkood, qaar ka mid ah korodhka heerka cadaadiska dhiigga iyo caadi ah dhiigga xubnaha muhiimka ah ee nolosha. In xaaladda bedelay vasoconstriction chronic yimaado hypertrophy unugyada muruqa siman derbiyada markabka.

Iyada oo daaqa oo ka mid ah hababka magdhawga ee wadnaha oo shaqadiisa gaba, yaridu vascular biiray. Tani waxa ay yaraynaysaa tirada guud ee iska caabin ah durugsan, u xuub-ballaarinta yar xididdada, venules iyo qalintaanka.

Shiidaa habka kasta oo qalbiga ku jira in uu nasasho u shaqeeya waqti dheer, ama burburka dhismaha dhaca myocardium ah, dhirfinaya failure oo ka mid ah wadnaha iyo xididdada. Sida dhaqanka shows, inta badan gobolka arkay on asalka ah ee cudurada sida cudurka wadnaha oo halbowle, cudurka wadnaha valvular (heleen oo lagu dhasho), myocarditis, xaaladda hypertensive, cardiomyopathy. Intaa waxaa dheer, cudurka ku dhici kara cudurada dheefshiidka lesions dabiiciga ah hormoonada jidhka, nafaqada aan ku filnayn.

Sababta ugu badan ee dhimashada (80% kiisaska) inta lagu jiro cudurka wadnaha waa cudurka halbowlaha wadnaha.

Si cudurka keeni kartaa sababo kala duwan. Khubaro jira saddex kooxood oo ugu waaweyn ee arrimaha etiological.

Kooxdu waxay ugu horeysay waxaa ka mid ah arrimo in ay leeyihiin a waxyeelo toos ah myocardium ah. Waxay noqon kartaa dhaawacyada jirka, soo-gaadhista kiimikada (tusaale ahaan, badinta daroogada). Intaa waxaa dheer, waxyeelo toos ah kartaan, iyo xaalado dabiici ah (sunta, wareer, dulin).

kooxda labaad ee ka mid ah sababaha arrimaha ay tahay cadhaysiinina dollar ah oo ka mid ah dabeecadda aassaasiga myocardial. Waxaa ka mid ah koror xad-dhaafka ah ee mugga dhiigga socda wadnaha ( "awoodda dollar"). Tani waxay dhici kara la'aan markii wadnaha waalka, extracardiac joogitaanka iyo intracardiac shunts, iyo in hypovolemia. dollar iyo sababaha myocardial kordhiyo iska caabin ah ku dul ejection ka saabka dhiigga wadnaha ah ( "dollar cadaadis"). Xaaladdan oo kale, failure wadnaha uu yeesho ay joogaan of hypertrophy myocardial. Waa in la ogaadaa in hypertrophy dhacdaa qaybta jidhka, kaas oo fuliya shaqada aad u daran.

Iyo koox saddexaad waxaa ka mid ah arrimaha ay tahay saamayn buux ventricular diastolic ah oo yaraada. Xaaladani waxay waxaa keena hoos u dhac inta badan mugga dhiigga wareegaya (inta lagu jiro lama filaan ah u xoog badan ama dhiig la'aan), iyo xad gudub in nasashada diastolic waxyaalaha qalbiga ku jira intii lagu riixo oo ay dareere ah kaas oo ururayaa in pericardium ah (dhiig, transudate, exudate).
