Pulmonary Embolism Caused by Intravenous Leiomyosarcoma of the Lower Limb.

Pulmonary embolism (PE) is usually caused by thrombosis or tumor. We report the long-term survival of a patient with PE due to a leiomyosarcoma in the deep vein. A 71-year-old woman complained of dyspnea and swelling of the left lower limb.

High serum erythropoietin level is associated with smaller infarct size in patients with acute myocardial infarction who undergo successful primary percutaneous coronary intervention.

Objectives: We investigated whether a higher serum erythropoietin (EPO) level in patients with acute myocardial infarction (MI) subjected to successful primary percutaneous coronary intervention (PCI) can predict a smaller infarct size determined by creatine kinase (CK) release.

Background: Erythropoietin has been shown to protect cardiomyocytes from ischemia-reperfusion injury in rodents.

Methods: We prospectively studied 101 patients with first MI who received successful primary PCI within 12 h from the onset of MI.
