1/42. Possible anaphylactic reaction to abciximab.We report a patient who experienced a severe anaphylactic reaction during coronary artery stenting. Subsequent to administration of a weight-adjusted dose of abciximab, the patient developed profound hypotension and severe, acute airway obstruction. The reaction was successfully reversed with a 16-hr infusion of epinephrine, steroids, and an H1 blocker. Cathet. Cardiovasc.

2/42. Noncardiogenic pulmonary edema associated with protamine administration during coronary artery bypass graft surgery.Protamine sulfate is the only agent approved to reverse heparin-induced anticoagulation. As with any other drug, protamine has the potential to cause adverse effects that range from mild hypotension to potentially fatal events, such as noncardiogenic pulmonary edema (NCPE) and catastrophic pulmonary vasoconstriction. We report a case of NCPE after the administration of protamine to a patient undergoing coronary artery bypass graft surgery and discuss the diagnosis and management of this severe adverse event.- - - - - - - - - - ranking = 5keywords = coronary (Clic here for more details about this article) |
3/42. An anaphylactic reaction possibly associated with an intraoperative coronary artery spasm during general anesthesia.We report a case of anaphylactic reaction occurring during general anesthesia that may have been accompanied by a coronary artery spasm. The present case and a review of the medical literature suggest that coronary artery spasm is evoked by common vasoactive mediators with anaphylactic reactions. Coronary artery spasm should be counted as a symptom of the cardiovascular manifestation of anaphylaxis. Clinicians should be aware of this possible complication when treating an anaphylactic reaction, especially in patients at risk for atherosclerosis. Early recognition of ST segment elevation is essential for diagnosis and treatment of coronary artery spasm.- - - - - - - - - - ranking = 7keywords = coronary (Clic here for more details about this article) |
4/42. Anaphylactoid reaction to etomidate: report of a case.We report an anaphylactoid reaction to etomidate twice in a 60-year-old male with coronary artery disease and peripheral vascular disease. Following the first anaphylactoid reaction, the patient developed myocardial infarction. In addition, the patient's blood was moderately positive for latex antibodies, which made the differential diagnosis difficult. We concluded that the patient had anaphylactoid reaction to etomidate due to the temporal relationship to induction with the drug. The patient did not manifest similar reaction to other induction drugs used for other surgeries. The patient recovered from both incidents of anaphylactoid reaction to etomidate following intravenous administration of epinephrine and fluids.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
5/42. Potential anaphylactic shock with abciximab readministration.A 46-year-old woman developed an anaphylactic reaction during percutaneous coronary intervention after she was pretreated with prednisone and diphenhydramine for a known allergy to iodine. She developed pruritus, edema, and nausea, which were followed by bradycardia and shock, minutes after administration of a bolus and standard-dose infusion of abciximab. The reaction was treated successfully with epinephrine, methoxamine, hydrocortisone, atropine, furosemide, sodium bicarbonate, diphenhydramine, and ranitidine.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
6/42. methylene blue: an effective treatment for contrast medium-induced anaphylaxis.BACKGROUND: The purpose of this paper is to propose methylene blue as a lifesaving alternative drug for the treatment of contrast-induced anaphylaxis. CASE REPORT: In a cardiovascular catheterization laboratory invasive hemodynamic monitoring was used to document the lifesaving effect of IV bolus injections of 1.5-2 mg/Kg methylene blue solution to treat three patients for anaphylactic shock following radiocontrast injection during coronary angiography. methylene blue administration was followed by prompt circulatory improvement, leading to hemodynamic stabilization and relief of other anaphylactic symptoms in each case. There were no deaths. CONCLUSIONS: Our findings suggest that methylene blue can be lifesaving in anaphylactic shock, notwithstanding some transitory side effects, such as cardiac rhythm disturbances and chest pain, both of which possibly originate from sudden myocardial perfusion deficits.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
7/42. Coronary artery spasm and acute myocardial infarction in naproxen-associated anaphylactic reaction.We present the case of a 43-year-old man who suffered an acute myocardial infarction after oral administration of 250 mg of naproxen, prescribed as antiinflammatory-analgesic agent after tooth extraction. Both intradermal skin test and human basophil degranulation test were positive to naproxen. These findings suggest a naproxen-associated anaphylactic reaction with concomitant coronary artery spasm and posteroinferior infarction, a clinical event previously not reported with the use of this drug.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
8/42. A case of two adverse reactions.Low molecular weight heparins are now widely prescribed in the treatment of thromboembolic disease and acute coronary syndromes. anaphylaxis is a recognised but rare potentially life threatening side effect of heparin.Common clinical features of anaphylaxis are cardiovascular collapse, bronchospasm, cutaneous symptoms, angioedema, generalised oedema, or gastrointestinal symptoms. It is extremely rare, however, for patients to experience such dramatic and potentially life threatening consequences as seen in the case reported here. It has been shown that patients may be tolerant of certain low molecular weight heparins but sensitive to others.Adrenaline is regarded as the most important drug for any severe anaphylactic reaction. Administration by the intramuscular route produces significantly higher peak plasma concentrations compared with subcutaneous injection, which is clearly beneficial in the critically compromised patient. Current UK resuscitation Council guidelines support the use of 0.5 ml of 1:1000 adrenaline to be administered intramuscularly.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
9/42. myocardial ischemia due to severe amoxicillin allergy.A patient suffered a myocardial injury as a manifestation of anaphylactic reaction to amoxicillin-clavulanic acid administration. A cardiologic study (ergometry and catheterization) showed no obstructive coronary disease and prick test to amoxicillin was positive. anaphylaxis may cause myocardial injury and the mechanism is likely to be vasospasm induced by mast cells and basophil mediators.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
10/42. Gadopentetate dimeglumine as a potential alternative contrast medium during percutaneous coronary intervention: a case report.BACKGROUND: There have not been previous reports of patients undergoing percutaneous coronary intervention (PCI) using a gadolinium chelate. methods AND RESULTS: A 74-year-old woman, who had a history of anaphylactic shock 4 times in response to iodinated contrast media despite preprocedural intravenous administration of hydrocortisone, was hospitalized because of unstable angina refractory to intensive medical treatment. Fully considering the risks of iodinated agents, digital subtraction coronary angiography and PCI were performed using gadopentetate dimeglumine without any side effects or complications. CONCLUSIONS: gadolinium chelates can be an alternative contrast media during PCI in particular patients with contraindications to iodinated media.- - - - - - - - - - ranking = 6keywords = coronary (Clic here for more details about this article) |
