| Abstract | 「要旨」安静時タリウム心筋シンチグラムで見られる右房描出は右心負荷の反映と考えられる. 高齢者に右房描出例の多いことに着目し, 加齢と右房描出の関連を検討した. 明らかな弁膜症および先天性心疾患のない291例を対象として, 安静時タリウム心筋シンチグラムにおける右房の描出の程度をRA 0:描出されず, RA 1+:軽度描出, RA 2+:高度描出の三段階に区分し判定した. 50歳未満RA 2+:0/43(0%), RA 1+:3/43(6.9%), RA 0:40/43(93.1%), 50歳代RA 2+:0/27(0%), RA 1+:6/27(22.2%), RA 0:21/27(77.8%), 60歳代RA 2+:3/60(5.0%), RA 1+:5/60(8.3%), RA 0:52/60(86.7%), 70歳代RA 2+:3/99(3.0%), RA 1+:46/99(46.5%), RA 0:50/99(50.5%), 80歳以上RA 2+:16/60(26.6%), RA 1+:22/60(36.7%), RA 0:22/60(36.7%)であった. 高年齢になるにしたがい右房の描出の頻度は増加し, 加齢とともに右房負荷の増加することが示唆された. |

| Abstract | [Summary]With Thallium-201 (Tl) myocardial scintigraphy, right atrial (RA) myocardium has been visible in the disease involving the right side of the heart. We have found RA visualization in the elderly patients without the evidence of right heart disease. Therefore, we studied the relation of age to the RA visualization with Tl myocardial scintigraphy performed at rest. Planar images of 291 patients without valvular or congenital heart disease were read by two observers and classified into the three by the degree of RA visualization; RA 0=not visualized, RA 1+ =moderately visualized, RA 2+ =intensely visualized, The results were as follows: 93.1 % of under 50 y.o., 77.8% of fifties, 86.7% of sixties, 50.5% of seventies and 36.7% of over 80 y.o. showed RA 0. 6.9% of under 50 y.o., 22.2% of fifties, 8.3% of sixties, 46.5% of seventies and 36.7% of over 80 y.o. showed RA 1+. None of under 60 y.o., 5.0 % of sixties, 3.0% of seventies, and 26.6% of over 80 y.o. showed RA 2+. In conclusion, RA visualization in Tl myocardial scintigraphy, suggesting right heart overload, may increase with aging. |
