In a surprising discovery, UCLA researchers have found that atherosclerosis, better known as hardening of the arteries, may arise in part through the formation of bone in the arteries. The finding, reported today in the Journal of Clinical Investigation, could open the door to new therapies to prevent atherosclerosis, which is treated by controlling intake of cholesterol and fats, said Dr. Linda Demer, associate chief of cardiology at the UCLA School of Medicine.

Los Angeles residents living near freeways experience a hardening of the arteries that leads to heart disease and strokes at twice the rate of those who live farther away, a study has found. The paper is the first to link automobile and truck exhaust to the progression of atherosclerosis -- the thickening of artery walls -- in humans. The study was conducted by researchers from USC and UC Berkeley, along with colleagues in Spain and Switzerland, and published this week in the journal PloS ONE. Researchers used ultrasound to measure the carotid artery wall thickness of 1,483 people who lived within 100 meters, or 328 feet, of Los Angeles freeways.

CT scans of Egyptian mummies, some as much as 3,500 years old, show evidence of atherosclerosis, or hardening of the arteries, which is normally thought of as a disease caused by modern lifestyles, researchers said Tuesday. The study, presented at the American Heart Assn. meeting in Orlando, Fla., was conceived by Dr. Gregory Thomas, a cardiologist at UC Irvine, after he read about Pharoah Merenptah at the Egyptian National Museum of Antiquities in Cairo. When he died at age 60 in 1203 BC, Merenptah was plagued by atherosclerosis, arthritis and dental decay.

For the first time, researchers have linked the hardening of arteries to blood clots in veins, a finding that could trigger new research in the effort to prevent the blockages that kill thousands of people each year. Italian researchers found patients hospitalized with unexplained deep-vein clots were nearly 2 1/2 times more likely to also have hardening of the arteries, or atherosclerosis, than patients with deep-vein clots attributed to other health problems.

Another study of transgenic mice has provided the first direct proof that high-density lipoproteins--HDL, the so-called "good cholesterol"--can protect against atherosclerosis, the buildup of fatty deposits in blood vessels. Such buildups clog the vessels, producing heart attacks.

Middle-age men who feel hopeless or think of themselves as failures may develop atherosclerosis, the narrowing of the arteries that leads to heart attacks and strokes, faster than their more optimistic counterparts, researchers report. People who expressed high levels of despair had a 20% greater increase in atherosclerosis over four years, according to a report in the August issue of the American Heart Assn. journal Arteriosclerosis, Thrombosis and Vascular Biology.
