Photos of patients’ EYES can be detected when they are likely to die of heart failure, claims studies after finding smaller pupils were linked to less survival with the condition
- Larger-eyed students are consistently more likely to survive heart failure, research found
- Researchers from Kitasato University Hospital in Japan saw the eyes of 870 patients
- People with smaller pupils are twice as likely to die and be in and out of the hospital
In the eyes of a patient with heart failure, doctors can tell how long they should live, a study has revealed.
Research has found that patients with larger eye pupils are consistently more likely to survive heartbeat and stay out of hospital.
The study photographed the eyes of 870 patients admitted with acute heartbeat.
The participants were then divided into those with large students, and those with smaller students.
The study, published yesterday by the European Society of Cardiology, found that people with smaller pupils were twice as likely to die.

Meanwhile, 47 percent of those with small students were readmitted to the hospital, compared with only 28 percent of those with large students.
Study author Dr Kohei Nozaki, from Kitasato University Hospital in Japan, said: ‘Our results suggest that pupil area is a new way to identify heart patients at increased risk of death or hospitalization.
‘This provides an opportunity to intervene and improve interviews.’
Heartbeat affects nearly one million people in the United Kingdom. It is a life-threatening condition in which the heart does not pump enough blood to meet the needs of the body. Symptoms include short circuit, swollen limbs and fatigue.
Up to 45 percent of patients admitted to the hospital with heart failure die within 12 months of admission, and the majority die within five years of admission.
Dr Nozaki said: ‘Finding better ways to determine which patients are more likely to be resuscitated or die is crucial.’
He explained that one of the causes of heart failure is the disrupted function of the body’s autonomic system, which controls heart rate, digestion and respiration.
Dr Nozaki said that pupil area is another way to assess autonomic function and has been used in patients with Parkinson’s disease and diabetes.
The new study examined whether pupil area prognosis could be predicted in patients with heart failure.
The study was conducted in 870 patients hospitalized for acute heart attack in 2012 to 2017. The mean age was 67 years and 37 percent were women.
Pupil area was measured in both eyes at least seven days after admission to hospital.
For the test, patients put on glasses, waited five minutes for their eyes to adjust to the darkness, then took pictures of the eyes. Patients were tested at a standard time, since the autonomic system is affected by time of day.
Patients were divided into the group of small pupils and a group of pupil areas according to their measurement below or above average.
Large pupil area was consistently associated with favorable survival – despite age, gender, and the presence of normal heart rhythm as atrial fibrillation.
Dr Nozaki added: ‘Student territory can be acquired quickly, easily and non-invasively.
‘Our study indicates that it could be used in day-to-day clinical practice to predict prognosis in patients with heart failure, including those who also have atrial fibrillation.
‘Patients with a small pupil area could be prioritized for cardiac rehabilitation with physical activity, which has been reported to improve autonomic function.’
He noted that pupil area cannot be used in patients with severe retinopathy or other eye diseases.
