3. Heart Failure

Breath tests could also determine heart failure or other underlying heart conditions, and this might become publicly available very soon. According to a paper published in the Journal of American College of Cardiology, researchers were able to do exactly this.

Researchers at the Cleveland Clinic collected breath samples from 41 patients. With the help of mass spectrometric technology, they analyzed the samples for chemical compounds present in patients with heart failure. Of this group, 25 were correctly identified to have acute decompensated heart failure, and 16 other were found to have other cardiovascular issues, but not heart failure.
