[Spontaneous coronary spasm with reversible occlusion of the left coronary artery: a case report (author's transl)].

A spontaneous coronary spasm with a complete but reversible occlusion of the left coronary artery could be demonstrated by coronary arteriography in a patient with angina pectoris at rest and during exercise. This will prove that spasms of coronary arteries can cause angina pectoris or even acute myocardial infarction if the spasm is persisting for long enough and if there is no sufficient supply by collateral vessels. This can be a possible reason for akinesia or dyskinesia of the left ventricle associated with normal or near normal coronary arteries.
