Erectile dysfunction medication found to intensify abdominal aortic aneurysms in mice

In a laboratory study in mice, sildenafil, a commonly used erectile dysfunction medication, was found to worsen abdominal aortic aneurysms, indicating additional research may be needed to determine if the medication may have the same effect on people, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Researchers evaluate hemodynamic factors related to aneurysm formation

Researchers in Japan have evaluated hemodynamic factors that may help identify sites where aneurysms are likely to form. Detailed findings of this study are described in the article "Computational fluid dynamic analysis of the initiation of cerebral aneurysms" by Soichiro Fujimura et al., published today in the Journal of Neurosurgery.

Thrombolytic therapy may be safe for people with ischemic stroke and unruptured aneurysms

Clot-busting drugs are the main treatment for stroke, but they have often not been recommended for people who have an aneurysm in their brains that has not ruptured. An aneurysm is a bulge in the wall of a blood vessel in the brain.
