Peripartum myocardial infarction associated with coronary spasm and acquired protein S deficiency

Coronary spasm and thrombosis associated with myocardial infarction in a patient with nearly normal coronary arteries.

A 37-year-old man presented with an evolving inferior myocardial infarction. Coronary angiography performed within 3 hours after the onset of the pain showed spasm of the right coronary artery and the presence of intracoronary thrombi. After resolution of spasm and the disappearance of thrombi, angiography revealed nearly normal coronary arteries. An ergonovine test was positive when the patien...

Magnesium deficiency in patients with recent myocardial infarction and provoked coronary artery spasm.

This study sought to clarify the relationship between magnesium (Mg) deficiency and coronary artery spasm provoked by pharmacologic agents in patients with a recent acute myocardial infarction (AMI). Twenty-three consecutive patients suffering from AMI were investigated with a Mg retention test (Mg: 0.1 mmol/kg for 4 h) in both the acute phase (within I week (3+/-2 days) of onset) and the subac...

Hyperthyroidism-associated coronary spasm: A case of non-ST segment elevation myocardial infarction with thyrotoxicosis

Hyperthyroidism is associated with many heart diseases. Thyrotoxic state has a relationship with coronary spasm. We present a case of a non-menopausal woman with hyperthyroidism who complained of chest pain. The diagnosis of coronary spasm was confirmed by coronary angiography (CAG). She is treated well with anti-thyrotoxicosis and anti-anginal medication. We recommend not use CAG as the first ...

Lacunar infarction in child with Protein S deficiency: a case report

Abstract Arterial ischemic stroke defines as a new focal neurologic deficit that lasted 24 hours or longer. Stroke is relatively rare in children and incidence of cerebrovascular disease is 1 per 4000 in neonates and 1 per 7000 to 1 per 70000 in older children (1 month to 18 years). Protein S deficiency is one of the causes of the stroke in children. Major manifestations of protein S deficienc...
