Tiny pumps can help when heart failure advances

Left ventricular assist devices support the heart while waiting for — or in place of — a heart transplant. These pumps have been around in one form or another for years. But advances in engineering and medical technology have made them small enough for almost anyone and portable enough to let their users take a walk, go shopping, and even travel. The devices don't work magic, and they come with big personal and financial costs. But they can offer months or years of extra life for people with failing hearts. More »

Experts call for home blood pressure monitoring

  About 73 million Americans — nearly half of them women — have hypertension (high blood pressure), a condition that propels blood too forcefully through blood vessels, increasing the risk of heart attack, heart failure, stroke, and kidney damage.

The expert panel that issued the statement was chaired by Dr. Thomas G. Pickering of Columbia University. The statement itself was jointly published online May 22, 2008, in the journal Hypertension and the Journal of Cardiovascular Nursing and in print in the Journal of the American Society of Hypertension (May 2008) and the Journal of Clinical Hypertension (June 2008).

It accounts for about one third of cases in women. However, determining the best way to treat it is a complex problem without a single, clear answer. The blockage may have come from scar tissue caused by a pelvic infection, endometriosis, or pelvic surgery. (Locked) More »
