Four patients with variant angina pectoris exhibited reproducible exercise-induced chest pain and ST-segment elevation. Coronary arterial spasm was documented with arteriography during exercise-induced ST-segment elevation (three patients) or after intravenous administration of ergonovine maleate (one patient). Our observations show that in patients with variant angina exercise can trigger coronary arterial spasm, thus inducing anginal pain and ST-segment elevation.
4例变异型心绞痛患者表现出可重复性的运动诱发胸痛和ST段抬高。在运动诱发ST段抬高时（3例患者）或静脉注射马来酸麦角新碱后（1例患者）通过动脉造影记录到冠状动脉痉挛。我们的观察结果表明，在变异型心绞痛患者中，运动可触发冠状动脉痉挛，从而诱发心绞痛和ST段抬高。
