1/4. Acute myocardial infarction secondary to coronary vasospasm during withdrawal from industrial nitroglycerin exposure--a case report.Industrial exposure to nitrates is known to produce acute and chronic effects on the cardiovascular system. A case of acute inferior myocardial infarction in a young, otherwise healthy, white male that occurred during the usual weekend withdrawal period is presented.- - - - - - - - - - ranking = 1keywords = cardiovascular system (Clic here for more details about this article) |
2/4. Anaesthetic management of a parturient with myocardial infarction related to cocaine use.cocaine abuse is common among parturients with an incidence of 11.8 to 20%. myocardial infarction is a rare and lethal event during pregnancy with an incidence of 1 in 10,000 pregnancies. We present the anaesthetic management of a parturient of 36 wk gestation who suffered a myocardial infarction nine hours before delivery which was temporally related to "crack" cocaine use. The patient's cardiovascular system became unstable following cocaine use, and she required mechanical ventilatory support and pharmacologic stabilization guided by invasive haemodynamic monitoring. This patient survived a non-Q wave myocardial infarction, but the prognosis of peripartum myocardial infarction remains poor with a mortality rate of 30-40% which is increased if the infarction occurs in the third trimester or postpartum period. The optimal mode and timing of delivery after myocardial infarction is unresolved. The association between cocaine use and myocardial infarction was first described in 1982, and cocaine remains unique among local anaesthetics in its ability to compromise the cardiovascular system through both sympathomimetic effects and vasoconstrictive effects on coronary arteries. Because of the prevalence of substance abuse, cocaine use should be considered in the differential diagnosis of sudden cardiovascular compromise in parturients.- - - - - - - - - - ranking = 2keywords = cardiovascular system (Clic here for more details about this article) |
3/4. coronary artery disease in young patients with systemic lupus erythematosus: two case reports.The cardiovascular system is often involved during systemic lupus erythematosus (SLE), but only few studies have documented myocardial ischemia and myocardial infarction in young patients. We observed 2 cases of coronary artery disease in young patients with SLE and different clinical presentations. In the first case, a 26-year-old woman, with SLE diagnosed at the age of 12 years, was evaluated for angina (CCS class II). Myocardial scintigraphy revealed a clear reversible thallium-201 apical perfusion defect. During the following 5 years worsening effort angina led to coronary angiography which revealed the presence of a complete obstruction of the left anterior descending coronary artery (LAD) treated with surgical myocardial revascularization (internal mammary artery implantation on the LAD). The second patient had myopericarditis and an acute myocardial infarction 1 year before coming to our observation. coronary angiography revealed the presence of 100% obstruction of the LAD. On this basis, a diagnosis of SLE was made. Our data constitute two relevant examples of coronary artery disease with different clinical presentation in young SLE patients.- - - - - - - - - - ranking = 1keywords = cardiovascular system (Clic here for more details about this article) |
4/4. Acute myocardial infarction caused by transnasal inhalation of amphetamine.A 42-year-old man developed acute myocardial infarction 20 minutes following transnasal inhalation of amphetamine. To our knowledge, no cases of amphetamine-induced myocardial infarction by transnasal inhalation have ever been reported. Consequently its pharmacological effects on the cardiovascular system are discussed.- - - - - - - - - - ranking = 1keywords = cardiovascular system (Clic here for more details about this article) |
