Cardiovascular Research:Electronic stent to provide feedback and therapy, then dissolve ♦Good cholesterol linked to lower risk of later heart disease

Study links better 'good cholesterol' function with lower risk of later heart disease  HDL, the 'good cholesterol' helps remove fat from artery walls, reversing the process that leads to heart disease. Yet recent drug trials and genetic studies suggest that pushing HDL levels higher doesn't reduce the risk of heart disease. Now, an epidemiological study shows that a person's HDL function -- the efficiency of HDL molecules at removing cholesterol -- may be a better measure of coronary heart disease risk and target for heart-protecting drugs.
Study identifies possible role for carbon monoxide in treating hemorrhagic stroke Carbon monoxide is typically associated with brain injury and neurological symptoms. But a new study suggests that when administered in small, carefully controlled amounts, CO may actually protect the brain from damage following hemorrhagic stroke.
Tiny heart, big promise: Understanding how cells become coronary vessels may lead to advances in repairing heart damage Studying zebrafish, investigators have discovered a new source for cells that can develop into coronary vessels and have identified the signaling protein, a chemokine called CXCL12, which guides this process
Heart: Electronic stent to provide feedback and therapy, then dissolve  Every year, an estimated half-million Americans undergo surgery to have a stent prop open a coronary artery narrowed by plaque. But sometimes the mesh tubes get clogged. Scientists have now developed a new kind of multi-tasking stent that could minimize the risks associated with the procedure. It can sense blood flow and temperature, store and transmit the information for analysis and can be absorbed by the body after it finishes its job
