| Abstract | 「要旨」 81mKr持続注入法を用い, 各種心疾患の右室の収縮および拡張動態を評価した. 右前斜位の心電図同期データより得られる右室容量曲線およびその一次微分曲線から, 収縮期指標としてEjection Fraction, Peak Ejection Rate, 拡張期指標としてPeak Filling Rate, Time to Peak Filling Rate, 1/3 Mean Normalized Diastolic Filling Rateをそれぞれ算出した. 収縮期指標は拡張型心筋症でのみ低下したが, 拡張期指標は肥大型心筋症, 高血圧心, 拡張型心筋症, 下壁梗塞症および一部の前壁中隔梗塞症で低下した. 81mKr持続注入法を用いた右室容量曲線の解析は, 各種心疾患の収縮および拡張動態の把握に有用と考えられた. |

| Abstract | [Summary] To evaluate right ventricular (RV) systolic and diastolic properties in patients with various heart diseases, RV volume curves obtained from 81mKr scintigraphy with continuous infusion were analyzed. The data were acquired in right anterior oblique position for five minutes, and from RV time activity curve and its first derivative curve, ejection fraction and peak ejection rate as systolic indices, and peak filling rate, time to peak filling and 1/3 mean normalized diastolic filling rate as diastolic indices were calculated. Ejection fraction in patients with dilated cardiomyopathy was lower than that in controls, but there was no difference in systolic indices among controls and patients with the other heart diseases. However, diastolic indices in patients with hypertrophic cardiomyopathy, patients with hypertensive heart disease, patients with dilated cardiomyopathy, patients with inferior myocardial infarction, and some patients with anteroseptal myocardial infarction were lower than those in controls. In conclusion, analysis of RV time activity curve by 81mKr scintigraphy with continuous infusion provides RV systolic and diastolic indices, which may permit evaluation of RV systolic and diastolic properties in various heart diseases. |
