Abstract

Presentation of acute ST segment elevation myocardial infarction in the setting of acute subclavian artery thrombosis in a patient who underwent coronary artery bypass grafting with a left internal mammary artery graft, which is not believed to have been previously described. We report a 75-year-old woman with presentations of dizziness, nausea, left-arm numbness, and a cold left hand, who later had chest pain develop. Acute ST segment elevation myocardial infarction was diagnosed, and both a computed tomography and an angiography disclosed a thrombus extending from the proximal portion of the left subclavian artery to the orifice of the left internal mammary artery. The patient was free from the previously listed symptoms after undergoing emergent thrombectomy, with complete extraction of the long thrombus from the subclavian artery. Unfortunately, she died of pneumonia and septic shock 1 1/2 months later.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
