Researchers found that small pupil patient give him a quick death. According to a study published in ESC Heart Failure, journal of the European society of cardiology (ESC), pupil size allows to predict death or need for urgent re-hospitalization. We are talking about patients with heart failure.
“Our results show that the area of the pupil is a new method of identifying cardiac patients with increased risk of death or re-hospitalization. This gives you the opportunity to intervene and improve the prospects for the patient,” said study author Dr. Kohei of Nozaki from the hospital of the University of Kitasato.
About 26 million people worldwide currently suffer from heart failure. This is a life-threatening condition in which the heart cannot pump blood as necessary. Symptoms include shortness of breath, swollen limbs and fatigue. Up to 45% of hospitalized patients-core die within one year after hospitalization. It is therefore important to know which patients are at risk of death or re-hospitalization.
The study was conducted among 870 patients hospitalized for acute heart failure during 2012-2017. The average age was 67 years, 37% women. We measured the area of two of the pupils, immediately after hospitalization. For the test, patients wore protective glasses, waited five minutes until their eyes adjusted to the dark, then done photos. Included other factors that could affect the forecast, such as body mass index (BMI) and renal function.
The patients were divided into groups with small and large pupils.
At the end of the study revealed that the mortality rate in the cores with large pupils were 28% less cases of re-hospitalization is 18% less.
“Our research shows that it can be used in daily clinical practice to predict prognosis in patients with heart failure, including those who also have atrial fibrillation”, – concluded the authors of a scientific work.
They noted that there are patients that this approach is not applicable – people with severe retinopathy or other eye diseases.
Earlier, the “Rambler” reported that scientists are learning to diagnose the approach of death by a blood test.
