| Abstract | 「要旨」 運動負荷心電図にて著明なST低下または, 陰性U波を示す234例を対象として, タリウム負荷心筋シンチグラフィにて正常灌流分布を示す症例の臨床的意義について検討した. 対象を, タリウム負荷心筋シンチグラフィにて正常灌流分布を示す群 (I群) 24例と, 異常灌流分布を示す群 (II群) 210例に分類した. I群は, II群に比し女性が多く, 冠動脈危険因子の合併は, 低い傾向を示した. 安静時心電図は左室肥大所見を呈するものが多かった. 負荷時心電図では, Up-slope typeのST低下を示す症例が多く, 負荷後速やかにSTが基線に戻る例が多かった. 有意冠動脈狭窄を呈するものは1例のみで予後は良好であった. タリウム負荷心筋シンチグラフィにおける正常灌流分布は, 負荷心電図上, 著明なST低下または, 陰性U波を示しても, 冠動脈造影の有無にかかわらず, 予後に関して非常に有用な所見であることが確認された. |

| Abstract | [Summary] The relationship between exercise thallium-201 scintigraphic findings and clinical features (chest pain, risk factors, resting electrocardiography, exercise electrocardiography and prognosis) was studied in the 234 patients with profound ST-segment depression (J80>=-2mm) or negative U wave in exercise electrocardiography. We classified these cases into two groups by exercise thallium perfusion; (I) normal thallium-201 perfusion (n=24) , (II) abnormal thallium-201 perfusion (n=210) . The incidence of female in group I was larger than that in group II. In resting electrocardiography, left ventricular hypertrophy was found more frequent in group I. In exercise electrocardiography, most of ST-segment depression in group I revealed up-slope type and a rapid recovery to baseline. Group I had lower incidence of cardiac events (cardiac death, nonfatal myocardial infarction, percutaneous transluminal coronary angioplasty, coronary artery bypass grafting) . In conclusion, normal thallium-201 perfusion in exercise thallium-201 scintigraphy was more useful indicator for prognosis, even if the patients had the findings of profound ST-segment depression or negative U wave in exercise electrocardiography. |
