Johns Hopkins Scientists Alter Fat Metabolism in Animals to Prevent Most Common Type of Heart Disease

Working with mice and rabbits, Johns Hopkins scientists have found a way to block abnormal cholesterol production, transport and breakdown, successfully preventing the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans. The condition develops when fat builds inside blood vessels over time and renders them stiff, narrowed and hardened, greatly reducing their ability to feed oxygen-rich blood to the heart muscle and the brain.

Right now, options are limited for preventing heart attacks. However, the day may come when treatments target the heart attack gene, myeloid related protein-14 (MRP-14, also known as S100A9) and defang its ability to produce heart attack-inducing blood clots, a process referred to as thrombosis.

Study Shows Link Between HIV Infection and Coronary Artery Disease

Men with long-term HIV infections are at higher risk than uninfected men of developing plaque in their coronary arteries, regardless of their other risk factors for coronary artery disease, according to results of a study led by Johns Hopkins researchers. A report on the research appears in the April 1 issue of Annals of Internal Medicine.
