To determine whether syncope predisposes to sudden cardiac death, variant angina patients with syncope during cardiac attacks were compared with those without syncope. There were 240 consecutive patients (193 males and 47 females) diagnosed with variant angina pectoris. Thirty patients had a history of syncope during cardiac attacks while the remaining 210 had none. The incidence of cardiac events in the former group was 10.0% (3 of 30) and 10.5% in the latter. There were 3 cases of sudden cardiac death, all in the latter group. Significant clinical variables in the syncope patients included inferior ST-segment elevation and serious arrhythmias. We conclude that there is no relationship between syncope during variant angina and sudden cardiac death.
为了确定晕厥是否易导致心源性猝死，将发作时出现晕厥的变异型心绞痛患者与未出现晕厥的患者进行了比较。共有240例连续诊断为变异型心绞痛的患者（193例男性和47例女性）。30例患者有发作时晕厥史，其余210例无晕厥史。前一组心脏事件的发生率为10.0%（30例中的3例），后一组为10.5%。有3例心源性猝死，均在后一组。晕厥患者的重要临床变量包括下壁ST段抬高和严重心律失常。我们得出结论，变异型心绞痛发作时的晕厥与心源性猝死之间没有关系。
