Presentation Transcript

  1. myocardial [′maiəu′ka:diəl]心肌的 infarction [in‘fɑ:kʃən]  梗塞 necrosis [ne‘krəusis]坏死 myocardium [,maiəu‘kɑ:diəm]  心肌 thrombus [‘θrɔmbəs]血栓

  2. occlude [ə‘klu:d]   阻塞 obstruct [əbˈstrʌkt]阻塞 platelet [‘pleitlit]  血小板 endothelial [,endəu‘θi:liəl]内皮的 atherosclerotic [,æθərəusklə‘rɔtik]动脉粥样硬化的

  3. plaque   [plæk] 斑块 thrombogenesis [′θrɔm‘bəu′dʒenisis]   血栓形成 ischemic [is′kemik] 缺血的

  4. Myocardial Infarction Ischemic myocardial necrosis usually resulting [is′kemik] [′maiəu′ka:diəl] [ne‘krəusis] from abrupt reduction in coronary blood flow to a segment of myocardium. In more than 90%of patients with acute MI, an acute thrombus, [‘θrɔmbəs]

  5. occludes the artery (previously partially [ə‘klu:d] obstructed by an atherosclerotic plaque) [əbˈstrʌkt] [,æθərəusklə‘rɔtik][plæk] that supplies the damaged area.

  6. Altered platelet function induced by [‘pleitlit]   endothelial change in the atherosclerotic [,endəu‘θi:liəl] plaque presumably contributes to throm- bogenesis. [′θrɔm‘bəu′dʒenisis]  

  7. 周二

  8. spontaneous [spɔnˈteiniəs] 自发的 thrombolysis [θrɔm‘bɔlisis] 血栓溶解 thrombotic [θrɔm‘bɔtik] 血栓形成的 occlusion [ɔ‘klu:ʒən]   闭塞 arterial [ɑ:‘tiəriəl]   动脉的 embolization [′embəlai′zeiʃən] 栓塞 mitral [‘maitrəl] 二尖瓣

  9. aortic [ei‘ɔ:tik]   主动脉瓣 infective [in‘fektiv]   传染的 endocarditis [,endəukɑ:‘daitis]   心内膜炎 marantic [mə‘ræntik]     消耗的 spasm [ˈspæzəm] 痉挛 Cocaine [kəuˈkein] 可卡因

  10. Spontaneous thrombolysis occurs in about [spɔnˈteiniəs] [θrɔm‘bɔlisis] 2/3 of patient so that, 24 hours later, thrombotic occlusion is found in only about [θrɔm‘bɔtik] [ɔ‘klu:ʒən]   30%. MI is rarely caused by arterial embolization [ɑ:‘tiəriəl]  [′embəlai′zeiʃən]

  11. (in mitral or aortic stenosis, infective [‘maitrəl] [ei‘ɔ:tik]   [in‘fektiv] endocarditis and marantic endocarditis ) . [,endəukɑ:‘daitis]   [mə‘ræntik] MI has been reported inpatients with coronary spasm and otherwise normal [ˈspæzəm]

  12. coronary arteries. Cocaine causes intense coronary arterial spasm, and users may present with cocaine- induced angina or [æn'dʒainə] MI.

  13. 周三

  14. autopsy [ˈɔ:tɔpsi] 尸解 angiography [ændʒi‘ɔgrəfi]   血管造影术 superimpose [,sju:pərim‘pəuz]   把…放置在上面叠加 preexist    [‘pri:ig’zist]   事先存在 atheroma [,æθə‘rəumə]   动脉粥样化

  15. predominantly  [priˈdɔminəntli] 主要地 ventricle [‘ventrikl]   心室 atria [‘ɑtriə]   心房 circumflex [‘sə:kəm,fleks]   卷曲的 left circumflex artery 冠状动脉左回旋支 filling [‘filiŋ]   灌注、充填

  16. tricuspid [trai‘kʌspid]   三尖瓣的 regurgitation [ri,gə:dʒi‘teiʃən]     反流 cardiac [‘kɑ:diæk]    心脏的 characterize [ˈkæriktəraiz] 以…为特征

  17. Autopsy studies and coronary angiography [ˈɔ:tɔpsi][ændʒi‘ɔgrəfi] have shown that cocaine-induced coronary thrombosis may occur in normal coronary arteries or be superimposed on preexisting [,sju:pərim‘pəuz]    [‘pri:ig’zist] atheroma. [,æθə‘rəumə]  

  18. MI is predominantly a disease of the LV, but  [priˈdɔminəntli] damage may extend into the right ventricle (RV) [‘ventrikl]   or the atria.RV infarction usually results from [‘ɑtriə]   occlusion of the right coronary or adominant

  19. left circumflex artery and is characterized by [‘sə:kəm,fleks]  [ˈkæriktəraiz] high RV filling pressure, often with severe [‘filiŋ]   tricuspid regurgitation and reduced cardiac [trai‘kʌspid]  [ri,gə:dʒi‘teiʃən]   [‘kɑ:diæk]   output.

  20. 周四

  21. dysfunction [dis‘fʌŋkʃən]    机能障碍 inferior [inˈfiəriə] 劣等的、下级的 posterior [pɔˈstiəriə] 后面的 hemodynamic [,hemədai‘næmik]   血液动力学 jugular [‘dʒʌgjulə]   颈静脉的 venous [‘vi:nəs]   静脉的

  22. pump [pʌmp] 泵 cardiogenic    [,kɑ:diəu‘dʒenik]   心脏性的 anterior   [ænˈtiəriə] 前面的 prognosis [prɔg‘nəusis]   预后 hypotension[,haipəu‘tenʃən]   低血压

  23. Some degree of RV dysfunction occurs in about half [dis‘fʌŋkʃən] of patients with an inferior-posterior infarction, [inˈfiəriə][pɔˈstiəriə] producing hemodynamic abnormality in 10% to 5%. [,hemədai‘næmik] RV dysfunction should be considered

  24. in any patient with inferior-posterior infarction and elevated jugular venous pressure with hypotension [‘dʒʌgjulə] [‘vi:nəs]   [,haipəu‘tenʃən] or shock .The ability of the heart to continue functioning as a pump relates directly to the extent [pʌmp] of myocardial damage.

  25. Patients who die of cardiogenic shock usually have [,kɑ:diəu‘dʒenik] an infarct, a combination of scar and new infarct, of more than 50% of LV mass. Anterior infarcts tend to [ænˈtiəriə] be larger and have a worse prognosis than inferior- [prɔg‘nəusis]   posterior infarcts.
