New breathprint test can predict heart failure

Acute decompensated heart failure (ADHF) is the most common reason for hospital admission, particularly in seniors; however, identifying at-risk individuals before symptoms become evident has been inadequate. Now, a new breathprint test, using a single exhaled breath, can detect impeding heart failure. The test could lead to interventions that could reduce the need for hospitalization. Researchers affiliated with the Cleveland Clinic published their findings in the April edition of the Journal of the American College of Cardiology.

The researchers note that previous studies have identified elevated acetone, pentane, and nitric oxide levels in the exhaled breath of heart failure patients correlated with disease severity. A technique known as selected ion-flow tube mass-spectrometry (SIFT-MS) combines a fast flow tube technique with quantitative mass spectrometry that is ideally suited for exhaled breath analysis because it allows for the analysis of small and humid samples without the need for cumbersome sample preparation or calibration. In addition, scan times are relatively brief. Using this technology, the investigators conducted a prospective (forward-looking) study to evaluate the feasibility of exhaled breath analysis to identify patients admitted for ADHF.
