‘Simple blood test could warn of heart attack risk’

A simple and cheap blood test could warn people if they are at risk of suffering a heart attack within five years, researchers have said.

Scientists have linked high levels of antibodies produced by the immune system and a low likelihood of heart problems in the “exciting” research.

The test looks for levels of IgG antibodies which appear to prevent a heart attack even if cholesterol and blood pressure levels are high. IgG is found in all bodily fluids and protects against bacterial and viral infections.
