Men with hematopoietic mosaic loss of Y chromosome have worse prognosis for heart failure

research group led by Dr. Soichi Sano, a specially appointed lecturer in the Department of Cardiovascular Medicine, Graduate School of Medicine, Osaka Metropolitan University, revealed that men with hematopoietic mosaic loss of Y chromosome (mLOY) — meaning men with an increase, in the blood, of cells that have lost the male sex chromosome — have a worse prognosis for heart failure due to fibrosis progression in the heart.

WEB device found to be safe and effective in treating sidewall brain aneurysms

A novel mesh plug that has been traditionally used to treat brain aneurysms occurring where the blood vessels branch out was found to be equally effective in treating aneurysms on the side of the vessel, according to a study in the journal Radiology.

People with elevated blood pressure upon standing more likely to have risk for cardiovascular events

Among young and middle-aged adults with high blood pressure, a substantial rise in blood pressure upon standing may identify those with a higher risk of serious cardiovascular events, such as heart attack and stroke, according to new research published today in the American Heart Association's peer-reviewed journal Hypertension.

Studies compare endovascular therapy and microsurgery for treating wide-neck aneurysms

Aneurysms are weak, bulging portions of blood vessel walls. These blood-filled sacs resemble balloons in structure and have necks like balloons. Some aneurysms have larger necks and are called "wide-neck" aneurysms.

Study may pave the way for mechano-medical approaches to treating abdominal aortic aneurysm

Abdominal aortic aneurysm (AAA) is a complex and life-threatening vascular disease with high incidence worldwide. Termed the silent killer, most AAAs are asymptomatic, often going undetected until rupture, and involve a poorly understood set of mechanical and biochemical events.

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.
