An 86-year-old woman was admitted to our hospital because of vomiting and anorexia. Although serum cardiac markers, an electrocardiogram, and echocardiography suggested acute myocardial infarction, emergency cardiac catheterization revealed akinesis of the left ventricular apex without significant coronary artery stenosis. ⋯ She died of worsening heart failure on day 14. We discuss this serious clinical course of a very elderly patient with takotsubo cardiomyopathy.

Spinal cord ischemia may develop into paraplegia in some cases during operation of the thoracoabdominal aorta. This is attributable to the vulnerability of spinal motor neurons to ischemia. In this study, iloprost was used as an agent to decrease the severity of ischemia and reperfusion injury to the spinal cord motor neurons. ⋯ The number of viable cells was higher, whereas the number of nonviable cells was lower in iloprost group, when compared with the control group (P<0.05). Higher numbers of viable motor neurons were consistent with the neurological findings. As a result of this study we concluded that iloprost infused during clamping of the aorta mitigates the spinal cord injury due to ischemia and reperfusion, and has a significant protective effect.
