Lowest Blood Pressure, Cholesterol Levels the Best

MONDAY, March 23 -- The tightest control of the major risk factors for heart disease seems to provide the greatest protection against cardiovascular trouble, a new study shows. And so the current guidelines for risk factors such as blood pressure and LDL cholesterol might need to be tightened even further, said Dr. Stephen J. Nicholls, an assistant professor of molecular medicine at the Cleveland Clinic, and author of the report, which appears in the March 31 issue of the Journal of the American College of Cardiology. "It is clear that each benefit we have in terms of lowering LDL cholesterol and blood pressure is going to be important, and the lower you get those measurements, the better," Nicholls said. Nicholls and his colleagues looked at data on the arteries of 3,437 men enrolled in seven different trials at the Cleveland Clinic. The arteries were examined by ultrasound probes that provided information on the volume of the fatty deposits in the linings of the blood vessel ...

Scientists Find Link between Vertigo and Osteoporosis

Scientists in Korea found that people with osteoporosis, a disease that lowers bone density and increases risk of fracture, are also more likely to have vertigo, a dizziness disorder caused by problems in the inner ear. The study was the work of Dr Ji Soo Kim, of Seoul National University College of Medicine in Korea, and colleagues, and is published in the 24 March issue of the journal Neurology. For the study, Kim and colleagues examined 209 people with benign positional vertigo (BPV) for which there was no known cause and compared them with 202 people with no history of dizziness (the controls). BPV can sometimes result from ear surgery or head trauma and is thought to be when crystals of calcium carbonate become loose and move around in the tubes of the inner ear that help people to balance. For the osteoporosis data, the researchers used the bone mineral density measures of front and back lumbar spine and femur of the participants. After adjusting for age, sex, alco ...

Treating metabolic disorders may aid neurologic health

Researchers are investigating previously noted connections between metabolic and neurologic disorders. By doing so, they are identifying possible ways to delay the onset of such diseases as Alzheimer's and other dementias, or at least slow their progress. For instance, because evidence suggests diabetes increases the risk of Alzheimer's disease and vascular dementia, good blood glucose control could serve to hold off the serious neurologic conditions, according to research in the March Archives of Neurology. The theme issue on neurological disorders related to metabolic diseases contains several studies that cover links between cognitive decline and metabolic syndrome in women, extra pounds in older men, and an accumulation of heart disease risk factors and insulin resistance in older men and women. The nation's aging population virtually guarantees the number of people with Alzheimer's will climb. During the next 50 years, the disease's incidence and prevalence, as well as ot ...
