Utility of routine pretreatment evaluation of left ventricular ejection fraction in breast cancer patients receiving anthracyclines.

Anthracycline-based chemotherapy is widely used in the management of breast cancer. Despite the lack of clinical evidence, obtaining prechemotherapy left ventricular ejection fraction (LVEF) by echocardiogram or multigated acquisition scan is a widely adopted practice throughout the world. We present here the results of a retrospective analysis of breast cancer patients who had LVEF measurements in anticipation of an anthracycline chemotherapy to determine whether predefined cardiac risk factors predicted for poor cardiac function.

Cocaine-induced postpartum coronary artery dissection: a case report and 80-year review of literature.

The incidence of cocaine-induced myocardial infarction (MI) in pregnancy is unknown. During the peripartum period, cocaine-abusing women are highly susceptible to MI caused by the effect of cocaine on a heart that is already stressed by hemodynamic changes of pregnancy. MI is an infrequent event during pregnancy and the peripartum period, with an estimated rate of 1 in 16,000 patients.
