(ORDO NEWS) — Scientists have found a new indicator of the risk of early death in patients with heart failure. Pupil size may indicate this, according to a study published in the journal ESC Heart Failure.
According to the report, doctors followed a group of 870 people, who were later divided into patients with large and small pupils. The subjects were followed for the next two years.
As it turned out, those suffering from heart failure with small pupils died twice as often as those with larger pupils. In addition, they were almost 50 percent likely to end up in the hospital again, while patients with large pupils returned 28 percent of the time.
“Observations have shown that measuring the area of the pupil may be a new non-invasive method for assessing the condition of patients with heart failure,” – follows from the conclusions of the scientists.
Doctors remind that pupil examination is already actively used in diagnosing the condition of patients with Alzheimer’s disease, Parkinson’s disease, diabetes mellitus and others. It is noted that the search for reliable non-invasive methods for determining health risks is one of the most important tasks for physicians.
