Diastolic kusagadzikana kunoreva kusakwanisa kwemutsipa wemwoyo kuti uzorore kazhinji mushure mekubata kwemwoyo. Sezvo iri panguva yechikamu chekuzorodza (chinonzi "diastole") kuti mhepo yemhepo inokonzera mhepo (iyo huru yekuputira makamuri ) izere neropa mukugadzirira kwechipiri chemoyo, kusagadzikana kwe diastolic kunogona kukanganisa kuzadza mwoyo.
Kuzadza uku kusina simba kunogona kuvhara kuwanda kweropa mwoyo inogona kuputira nemoyo umwe neumwe uye inogona kuwedzera zvinetso mumoyo.
Dambudziko re diastolic rinogona kukonzera kuti diastolic mwoyo isakundikana, zvakare.
Zvakajeka zvezviratidzo
Diastolic dysfunction pachake kazhinji haisi zviratidzo zvachose. Mutungamiri mukuru, zvishoma nezvishoma kuenderera mberi kwekudzivirira kwemishonga kunogona kuitika. Zvisinei, vanhu vazhinji vane diastolic dysfunction havacherechedzi chiratidzo ichi kana nokuti vanotora mararamiro ehupenyu (iyo ndiyo imwe yezvipingamupinyi zve diastolic dysfunction) kana kuti vanoziva zvishoma nezvishoma kuderedza basa ravo kuti vatsigire kukanganisa kwavo kukwanisa kuzviita.
Asi, apo diastolic mwoyo kukundikana kunopinda, zviratidzo zvinowanzoonekwa. Nepo zviratidzo zvinowanikwa ne diastolic mwoyo kusakatika zvakafanana nezviratidzo zvinowanzoonekwa nevanhu vane imwe nzira yemoyo inokundikana , zviratidzo zvemapurmoni-zvinokonzerwa nemapapu kusangana-zvinowanzonyanya kuve kune avo vane diastolic mwoyo kusakundikana.
Dyspnea yakasimba (kufema), kazhinji inosangana nekukanganiswa nekufema nekukurumidza, ndiyo inoratidzirwa ye diastolic mwoyo kukundikana.
Uyezve, zviratidzo zvinowanzoitika mune zvikamu zvisingatauriki uye zvisingabvumirwi.
Izvi zvakasiyana-siyana zvakasiyana nemuenzaniso unowanzoonekwa kuvanhu vane "mararamiro" emhando dzekushaya simba kwemoyo umo kunotanga kwe dyspnea kunowedzera kuwedzera, zvichiitika kwemaawa kana mazuva.
Izvo zvinokonzera, zvakaoma kufema zvinetso zvinowanikwa ne diastolic mwoyo kusakatika zvinonzi sezvikamu zve "flash pulmonary edema ."
Izvi zvikamu zve flash pulmonary edema zvinogona kukonzerwa nedzimwe mamiriro ezvehutano, kusanganisira friday friction uye mamwe marudzi e tachycardia (nokukurumidza mwoyo miviri), nguva dzehutano hwepamusoro (high blood pressure, kunyanya systolic blood pressure elevations ), uye zvikamu zvemutima ischemia .
Chimwe nechimwe chezvipatara izvi chinogona kukonzera kuora kwemweya mukati memwoyo ye diastolic uye kunogona kukonzera munhu ane diastolic yakaremara kudzvinyirira pamusoro pemucheto. Uyewo, apo zvikamu zvekutsvaga pulmonary edema zvinoonekwa sechiratidzo chekushaya simba kwemwoyo, vanhu vane chirwere ichi vanowanzosangana nekuderera zvakanyanya uye zvishoma nezvishoma zvishoma nezvishoma zve dyspnea.
Maitiro Azvo Anoongororwa
Diastolic moyo kukundikana kunoonekwa kana munhu ane chikamu chekushaya simba kwemoyo uye kuongorora kunotevera kunoratidza kuti systolic basa remwoyo (kureva kuti, kukwanisa kwaro kukonzera ropa nechisimba kupemha chiito) kwakajairika.
Kuti vataure nenzira imwe, vane mwoyo wekukundikana pasinei nokuti vane chikamu chinowanzosara chinonzi ventricular ejection fraction . Mumakore achangobva kupfuura mapurisa emapurisa akaziva kuti kusvika makumi mashanu kubva muzana yevanhu vanotsvaka rubatsiro rwechiremba mune zvikamu zvehutachiona hwemapirmoni inokonzera inenge iine diastolic mwoyo kusakundikana.
Diastolic dysfunction inogona kuongororwa ne-echocardiogram, iyo inogona kuongorora maitiro e-diastolic yekudzikinura uye chidimbu chekusiya ventricular " kuoma ." Echocardiogram dzimwe nguva inogonawo kuratidza chikonzero che diastolic kudzvinyirira kune vamwe vanhu.
Semuenzaniso, echocardiogram inogona kuratidza kuti yakasara yakasara ye ventricular muscle (kureva, ventricular hypertrophy) inobatanidza nehutachiona uye hypertrophic cardiomyopathy . Inogonawo kuratidza kuvapo kwe aortic stenosis kana kuti yekudzivirira chirwere chema cardiomyopathies . (Zvose izvi zvinogona kubudisa diastolic kusagadzikana.)
Zvisinei, kune vanhu vazhinji vane diastolic dysfunction, echocardiography haicharatidzi chimwe chinhu chisina kunaka kuti tsatsanangurire kuti nei chiitiko chiripo.
Mune varwere, hazvibviri kutaura kuti chinokonzera chinetso che diastolic.
Inonyanya Kudii Diastolic Dysfunction?
Diastolic dysfunction yakanyanya kudarika kupfuura vanonzi cardiologists vaifunga kufunga. Zvimwe zvidzidzo zveEchocardiographic dzakaona kuti diastolic inoshaya simba mu15 muzana yevanhu vasati vava nemakore makumi mashanu uye mune 50% yevanhu vanopfuura makumi manomwe.
Diastolic kudzvinyirira inonyanya kurwara kwevakadzi, zvakare. Kusvika 75 kubva muzana yevanhu vanoona kuti vane diastolic moyo kusakatika ndevakadzi.
Diastolic mwoyo kusagadzikana kunoratidzwa apo munhu ane diastolic dysfunction anoumba chikamu chepummonary congestion yakaoma zvakakwana kuita zviratidzo. Kana chikamu che diastolic mwoyo kukanganisa kunoitika kamwechete, zvinonyanya kuitika zvakare, kunyanya kana kurapwa kuchiitika.
Shoko Rinobva
Mumakore achangobva kupfuura, nyanzvi dzechirwere dzakasvika pakuziva kukosha kwechirwere che diastolic uye kuti iyo yakave yakanyanya kufanana nezvakaitika kare. Izvo zvakakosha kune chero munhu ane diastolic kusagadzikana kutora chirwere ichi zvakanyanyisa uye kushanda pamwe nevanachiremba kuti vagadzire nzira yakakwana yekuzadzisa mhinduro yakanaka uye ine utano.
