Depression related to poor health after bypass surgery

Men who are depressed before their coronary artery bypass graft surgery are more likely to be re-hospitalized or suffer pain and reduced quality of life six months after their bypass operation, compared with men who are not depressed before the surgery, according to new research. Rates of hospitalization for heart attack or artery disease rose among bypass patients with pre-operative depression, say Matthew M. Burg, Ph.D., of the VA Connecticut Healthcare System and colleagues.

Scientists develop new blood test for heart disease

Scientists have developed a rapid new blood test which may help predict the likelihood of a heart attack. The research published in Nature Medicine shows how a new science called Metabonomics can be used to test for coronary artery disease, using minimally invasive procedures. The test, which only needs a few drops of blood, measures the magnetic properties of molecules in blood using high frequency radio waves, which are then analysed using an advanced computer programme capable of detecting abnormal patterns of signals associated with heart disease.
