2. HEART FAILURE
One team of scientists was able to detect heart failure through an analysis of patients’ breath. The test was originally used to detect kidney failure using a breath test. The heart patients were merely used as a control. It did not take long for the researchers to realize that the heart patients also had their own unique “breath prints.” Their 2012 study could revolutionize the way that doctors are able to detect heart disease by providing a non-invasive alternative test for diagnosis.
