A septal infarct is an area of dead tissue in the septum of the heart, which divides the two sides of the heart. It often follows a heart attack.

Heart tissue that spent one month in space was found to beat irregularly, while proteins and mitochondria in heart cells became dysfunctional.

After just 30 days in space, the heart tissue samples not only weakened, but also demonstrated irregular beating patterns and hallmark symptoms of aging.
