It's a common story: A middle-aged man who has recently received a clean bill of health from a physical exam suddenly drops dead of a heart attack. Despite great strides in diagnosing heart disease and treating it with a wide range of increasingly sophisticated technologies, doctors still fall short of accurately predicting which patients are at greatest risk of suffering a heart attack.

For patients who visit an emergency room with chest pains, but who don't have an abnormal EKG or elevated troponin levels, a CT scan can send them home earlier than conventional diagnostic procedures, doctors reported Wednesday. The patients are exposed to higher levels of radiation and the cost is slightly higher, but those effects are offset somewhat by the increased peace of mind associated with leaving the hospital sooner, the team reported in the New England Journal of Medicine.

In a review of thousands of case histories that raises serious questions about medical competence, RAND Corp. researchers reported today that three common medical procedures are often performed unnecessarily--in one instance nearly a third of the time. The authors of the study said it raises far-reaching concerns about the extent of unnecessary medical treatments and underscores the need for patients to question their doctors closely and seek second opinions.

Utah basketball Coach Rick Majerus, who has been away from his team since November because of knee surgery, rested comfortably here Tuesday night after undergoing a 4 1/2-hour procedure to clear two blocked arteries at LDS Hospital. No immediate timetable was set for Majerus' return to the team. "He went through this procedure, it went well, and for us to [say] much more than that would be inappropriate right now," Utah Athletic Director Chris Hill said.

An estimated 10 million Americans, most of them elderly, suffer from macular degeneration of the eye, a disorder that robs them of fine vision for reading. Usually their only recourse is to use powerful magnification devices. Nothing can be done to stop macular degeneration, the loss of cells at the center of the retina that give one the ability to see close objects and read print, ophthalmologists say. "You can't repair it," said Dr. Leon Lane.

Healthy women who go through menopause naturally may lower their risk of heart disease if they take hormone therapy in the early years of menopause, according to a new study. The research is the latest contribution to the longstanding controversy on the merits of hormone therapy after menopause. Previous studies show that hormone therapy in women who are 10 or more years past menopause raises the risk of cardiovascular problems. However, the question of whether hormone therapy may prevent or slow the development of heart disease in younger menopausal women has been a subject of continued debate.

Widespread overuse of CT scans and variations in radiation doses caused by different machines -- operated by technicians following an array of procedures -- are subjecting patients to high radiation doses that will ultimately lead to tens of thousands of new cancer cases and deaths, researchers reported today. Several recent studies have suggested that patients have been unnecessarily exposed to radiation from CTs or have received excessive amounts, but two new studies published Tuesday in the Archives of Internal Medicine are the first to quantify the extent of exposure and the related risks.

Ever wonder what your chances are of having heart disease? A new, five-minute scan can evaluate your risk long before a heart attack occurs by detecting calcium-ridden plaque in major blood vessels. This high-speed scan, called the Ultrafast CT, will become as commonplace as mammography, proponents predict. It works on the same principle as conventional computed tomography (CT), which scans the body and produces computer images of tissue to detect disease and other abnormalities.

A higher percentage of African Americans and Latinos are receiving AIDS care than was the case only a couple of years ago, but the gap between men and women is not closing nearly as rapidly, according to a new study by Rand researchers. The uninsured and those relying on Medicaid also received poorer care than those with private insurance, and patients who contracted the virus via intravenous drug use or heterosexual contact were less likely to receive adequate care than gay males, Dr. Martin F.

Chickenpox in children is a relatively harmless infection that causes a rash and fever for a few days, then disappears. But Herpes zoster, the virus that causes chickenpox, doesn't leave when the chickenpox ends. Instead, it hides in the nervous system, often emerging decades later to cause a much more painful disorder called shingles.
