Shrunken pore syndrome increased the risk of acute kidney injury after cardiac surgery: a cohort study

Key takeaways

People with shrunken pore syndrome — a condition where tiny filters in the kidney become too narrow, measured by blood and urine tests — were more likely to suffer sudden kidney injury after heart surgery. This study followed 1,240 patients and found the risk more than doubled, but because it is observational, it shows a link, not proof that shrunken pores cause the injury.
