| Abstract | 「要旨」心筋梗塞の既往のない虚血性心疾患13例(うち不安定狭心症9例)に携帯用RI心機能モニター(VEST)を用いて, 平均2.1時間日常生活での心機能と心電図をモニターした. 8例に20回の一過性のEFの低下(6%以上)を認めた. この20回中12回は安静時にみられた. そのうち5回は胸痛などの自覚症状を伴い, うち4回は有意な一過性ST低下が認められる典型的な虚血発作であった. 一方無症状の15回のEF低下のうち4回はST低下を伴い, 無症候性虚血発作と考えられた. またVESTでは10回のST低下がみられたが, うち2回はEFの有意な低下を伴っていなかった. 虚血性心疾患例にVESTを用いて日常生活での心電図と心機能を合わせてモニターすることは, 虚血発作の検出だけでなく虚血の程度も評価でき, きわめて有用と考えられた. |

| Abstract | To assess incidence of ischemic episodes in patients with coronary artery disease (CAD), left ventricular function and electrocardiogram (ECG) were continuously monitored by an ambulatory ventricular function monitor (VEST) during daily activities for a mean of 2.1 hours in 13 patients with CAD. Nine were patients with unstable angina. This VEST detected 20 episodes of transient decrease in ejection fraction (>=6% below the baseline) in 8 patients. Five were symptomatic and 15 were symptom free. Among 5 symptomatic episodes, four were typical ischemic ones accompanied with ST segment depression on ECG. Among 15 asymptomatic episodes, 4 were associated with ST depression, which was highly suggestive of silent ischemia. However, 11 episodes of transient decrease in ejection fraction were not accompanied with either symptoms or ECG changes. On the other hand, the VEST detected 10 periods of ST depression, among which two were not associated with transient decrease in ejection fraction. We conclude that monitoring both ventricular function and ECG by the VEST is valuable for detecting and evaluating various episodes in patients with CAD. |
