• Ciwon Jiji na Jijiyoyin Jiki da Ƙunƙarar LumenKauri da kunkuntar bangon arteries na jijiyoyin jini na iya hana kwararar jini, wanda ke haifar da ischemia na myocardial.
• Ciwon Jiji na Jiji: Ƙara yawan ƙwayar tsokar zuciya yana haifar da karfin ɗaukar jini na arteries ya wuce.
• Thromboembolism na Jiji na Jiji: Toshewar da ke cikin arteries na jijiyoyin jini ba zai iya ɗaukar oxygen da abubuwan gina jiki zuwa myocytes ba.
• Myocyte Apoptosis: Shirye-shiryen mutuwar ƙwayoyin tsoka na zuciya yana haifar da tabarbarewar tsarin myocardial.

Menene binciken echocardiographic na ƙonewar cardiomyopathy a cikin kuliyoyi?
Gajiya cardiomyopathy wani yanayi ne wanda yawanci yana faruwa a cikin matakan ci gaba na hypertrophic cardiomyopathy (HCM). Echocardiography shine kayan aiki mafi mahimmanci don gano wannan cuta. Anan ga binciken echocardiographic:
1. Canje-canje na Lumen Ventricular: Lumen na ventricular, da farko ya kunkuntar, yana faɗaɗa sosai akan lokaci.
2. Kaurin bango: Ganuwar hagu mai kauri mai kauri da septum mai kauri ya zama sirara. Wannan bakin ciki yana haifar da raguwa a cikin kwangilar ventricular.
3. Rashin aiki na systolic: Ƙunƙwan huhu na hagu yana raguwa. Gajarta juzu'i Ana lura da raguwa mai mahimmanci.
4. Dilated Cardiomyopathy (DCM) -Kamar Bayyanar: Dilatation ventricular ya bayyana. Siffar echocardiographic yayi kama da DCM.
5. Dilation na Hagu Atrium: Hagu haɓakar bugun jini ya zama ruwan dare. Wannan haɓaka yawanci ana danganta shi da samuwar thrombus.
6. Tsarin Canji: Ana iya ganin canji daga ventricle mai kauri zuwa ventricle na bakin ciki wanda ke da tabarbarewar systolic da dilatation.
