Ergometrine-provoked coronary vasospasm on angiography without angina or ischaemia on ECG. A case report.
A 32-year-old White man suffered a large transmural inferoposterior myocardial infarction (MI). Coronary vasospasm is strongly suspected of having caused this MI since the ergometrine maleate provocation test gave rise to severe coronary vasospasm resulting in total occlusion of the dominant right coronary artery, without angina or ECG or haemodynamic features of myocardial ischaemia. This is a most unusual response to ergometrine maleate. Possible explanations are suggested and the implications are briefly discussed.
