Antioxidants seem to help protect lung function and prevent chronic obstructive pulmonary disease (COPD) among both smokers and nonsmokers, according to a new Cornell University study. Though the effects are different for smokers and nonsmokers, for both groups, the beneficial effects of high levels of antioxidants is dramatic.
Findings of a multicenter study indicate that Pacemaker Guided Monitoring has a high predictive value in determining heart transplant rejection. The use of an implanted pacemaker to detect heart rejection is much less invasive, more cost effective and without the major side effects associated with traditional endomyocardial biopsy.
Heart laser surgery termed Transmyocardial Revascularization can replace transplantation in certain patients with severe coronary artery disease. TMR patients experience survival rates of 85% which compare favorably with survival at one year post transplant. Due to the lack of sufficient numbers of donor hearts, TMR offers an alternative without the mortality associated with waiting for a transplant.

A surgical procedure performed to remove the fatty build-up in the carotid arteries leading to the brain has proven to reduce the risk of stroke. Stenosis, or blockage, in the carotid artery narrows the pathway for blood to travel to the brain. This build up can break off and block the flow of blood to the brain completely, causing a stroke and the ensuing brain damage.
The American Association of Neurological Surgeons (AANS) will hold its 66th Annual Meeting April 25 - 30, 1998 at the Pennsylvania Convention Center in Philadelphia, Pennsylvania.
