Ergometrine is recommended for use in the medical treatment of postpartum hemorrhage. Ergometrine can occasionally precipitate myocardial ischemia in the setting of significant anemia in women without preexisting cardiac risk factors, and it is important to recognize and treat myocardial ischemia in

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

Vasospastic ischaemia induced by the hyperventilation test in patients with a negative response to ergometrine.

We present the case histories of two patients with angina pectoris who developed coronary artery spasm in response to provocation with prolonged hyperventilation (verified by ST segment elevation in both and coronary angiography in one) despite a negative ECG response to intravenous injection of 0.4

Oesophageal spasm may mimic the pain of myocardial ischaemia. Forty-two patients who were thought to have angina until investigations failed to show any cardiovascular abnormality, were examined for oesophageal disease. Ergometrine provocation during oesophageal manometry caused significant

Tako-tsubo cardiomyopathy after administration of ergometrine following elective caesarean delivery: a case report.

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 haemodynamic response to myocardial ischaemia in ambulant patients with variant angina.

The haemodynamic response to myocardial ischaemia in patients with variant angina during ambulatory activity is unknown. Ambulatory pulmonary artery pressure monitoring with a transducer tipped catheter and simultaneous frequency modulated electrocardiograms was used to assess changes in left

Effects of renal dopamine receptor and beta-adrenoreceptor blockade on rises in blood angiotensin after haemorrhage, renal ischaemia and frusemide diuresis in the dog.

1. In chloralose-anaesthetized dogs, central venous and arterial angiotensin (AII) levels were monitored by blood-bathed bioassay during venous haemorrhage of 20 ml/kg, acute renal ischaemia induced by suprarenal aortic stenosis and frusemide-induced diuresis. 2. Blockade of intrarenal dopamine

Sequence and magnitude of ventricular volume changes in painful and painless myocardial ischemia.

Stimulation of left ventricular stretch receptors has been proposed as a possible mechanism for the occurrence of cardiac pain. Changes in left ventricular volume were continuously assessed in 12 patients during 11 spontaneous (two painful) and 12 ergometrine-induced (nine painful) ischemic attacks

Anterior myocardial infarction with coronary thrombus formation secondary to acute coronary vasospasm. A case report.

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.

Synthetic oxytocin as an antagonist of experimental cardiac anoxic changes in rabbits.

Synthetic oxytocin (Syntocinon) can be shown to reduce or abolish ST-T changes induced experimentally by hypoxaemia alone, by hypoxaemia and ergometrine, by vasopressin, and by a new procedure involving injection of small doses of picrotoxin into the lateral cerebral ventricle. Ventricular

The results of cardiac plexectomy in spastic angina are controversial. This study was undertaken to evaluate the effects of blocking the cardiac autonomic nervous system (CANS) in this syndrome in 61 patients presenting with chest pain and angiographically normal coronary arteries. All patients

[Value of negative U waves in coronary artery spasm].

The significance of U-wave inversion during coronary arterial spasm was investigated in 188 consecutive ergometric tests performed in 69 patients. All patients had previously undergone coronary arteriography which had clearly shown coronary spasm either at rest or after a single 0.4 mg injection of

Recurrent coronary artery spasm in the billowing mitral leaflet syndrome (primary mitral valve prolapse). A case report and review of the literature.

A 46-year-old White man had a 2-year history of frequent atypical chest pain associated with palpitations and presyncope. Clinical examination revealed an intermittent mid-systolic non-ejection click followed by a blowing mid-to-late systolic murmur indicative of the billowing mitral leaflet

BACKGROUND The safety of ergonovine/ergometrine stress testing for coronary vasospasm when performed outside the cardiac catheterization laboratory (cath lab) has been questioned vigorously. OBJECTIVE To assess the tolerability and safety of ergonovine/ergometrine stress testing performed in the
