Cardiovascular emergencies in the cancer patient.

摘要: Cardiovascular emergencies in oncology patients include all of the usual cardiac problems, as well complications cancer and its therapy. Pericardial effusions tamponade, masses, extrinsic compression heart great vessels by tumor or fluid collections may occur. Certain tumors secrete mediators that are directly toxic to heart; for example, catecholamines secreted pheochromocytomas serotonin is carcinoid tumors. Tumors can also cause arrhythmias due they secret direct mechanical irritation pericardium. Cancer therapy associated with emergencies. Perioperative myocardial ischemia infarction, arrhythmias, complicate surgery. tamponade follow surgery, radiation, chemotherapy. Chemotherapy anthracyclines, mitoxantrone, trastuzumab prompt acute chronic failure. 5-Fluorouracil causes coronary spasm some patients, leading angina, and/or sudden death. Cyclophosphamide, particularly high doses, produce myopericarditis. Radiation pericardial disease late sequelae such valvular insufficiency, effusive constrictive pericarditis. Endocarditis occurs association vascular access devices immune compromise. This review will discuss each these
