...Radioisotope scintigrams can reveal changes in hemodynamics, such as cardiac output and ejection fraction, and the extent of the infarcted area. Specialized tests include cardiac catheterization and selective coronary angiography. Cardiac catheterization can reveal decreased cardiac output, decreased ejection fraction, increases in left ventricular end-diastolic pressure, pulmonary artery wedge pressure, pulmonary artery diastolic pressure, and increased central venous pressure, while left ventricular angiography can reveal decreased contractility of the infarcted area, ventricular aneurysm formation, and the presence or absence of ventricular septal perforation. ... *Some of the terminology that refers to "coronary angiography" is listed below.

…放射性同位体によるシンチグラムでは,心拍出量,駆出率などの血行動態の変化と梗塞部位の広がりがわかる。なお,特殊な検査として,心臓カテーテル法と選択的冠動脈造影がある。心臓カテーテル法による検査では,心拍出量の減少,駆出率の低下,左心室拡張終期圧・肺動脈楔入圧・肺動脈拡張期圧などの上昇,中心静脈圧の上昇がみられ,左心室造影では,梗塞部の収縮性低下や心室瘤形成,心室中隔穿孔(せんこう)の有無が明らかとなる。… ※「冠動脈造影」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
