Ergot derivatives are frequently administrated during cesarean delivery, induced abortion, or post-partum hemorrhage to promote uterine contractions. Ergot derivatives may also induce coronary spasm and intravenous ergonovine is used in cardiac catheterization laboratories as a diagnostic agent.
An acute myocardial infarction in a young man when there was no fixed atherosclerotic lesion in the coronary arteries is reported. Soon after the myocardial infarction the patient was shown to have thrombosis in the anterior descending branch of the left coronary artery but this later disappeared.
A case of acute transmural anterior myocardial infarction in a 45-year-old Black employee of an explosives factory during a period of withdrawal from industrial nitroglycerin is documented. Angiography revealed that the patient had normal coronary arteries. Coronary vasospasm could not be induced by
A case of 'primary' mitral valve prolapse is documented. The patient was admitted with right-sided hemiplegia of sudden onset, probably caused by a cerebral embolus from the mitral valve. He also had a painless transmural inferior myocardial infarction (MI) of indeterminate age which was diagnosed
Ergometrine test was undertaken on the 1--3d day after hospitalization in 49 patients with unstable angina pectoris. Pain or ECG changes were recorded in 90% of patients. Reactions with the rise of the ST segment and changes of the T wave on ECG were interpreted as "spastic" and were seen in 43% of
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
BACKGROUND
Tako-tsubo cardiomyopathy (stress-induced cardiomyopathy or transient left ventricular ballooning) is characterized by clinical suspicion of an acute myocardial infarction with transient apical or midventricular dyskinesia of the left ventricle without significant coronary stenosis on
The association of a myocardial bridge of the left anterior descending (LAD) coronary artery and myocardial infarction is rare. The mechanisms by which the myocardial bridge could predispose to myocardial infarction are tachycardia (reducing the duration of diastolic coronary filling), thrombosis at
A 74 years old man was admitted as an emergency for syncopal attacks due to recurrent ventricular fibrillation (VF). These attacks were observed at the height of myocardial ischaemia as shown by ST elevation in Leads II, III and RV without associated anginal pain. Inferior myocardial infarction
A case of painless anteroseptal and high lateral wall infarction presenting as cardiogenic shock with pulmonary oedema 24 hours after childbirth complicated by severe post partum haemorrhage with a coagulation defect, is reported. Coronary angiography performed one month later was normal, with a
We treated a 23-year-old male with neurofibromatosis with acute myocardial infarction. Cardiac catheterization revealed severe organic stenosis in the left anterior descending artery, an ectasic left circumflex artery and a small right coronary artery. Percutaneous transluminal coronary angioplasty
We report a 30-year-old woman who developed an acute myocardial infarction at 24 weeks of gestation. She did not undergo any kind of acute intervention. On the 8th hospital day, premature delivery was performed safely following premature rupture of membrane. Coronary angiogram was normal and no
