Does exercise trigger coronary arterial spasm in patients with variant angina?
Exercise can trigger coronary arterial spasm in patients with variant angina, leading to anginal pain and ST-segment elevation.
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.
