Acute cardiac care & resuscitation
Cardiac arrest survivors’ self-reported cognitive function, and its association with self-reported health status, psychological distress, and life satisfaction—a Swedish nationwide registry study
Authors' conclusion
Survivors experiencing declined cognitive function post-CA are at a higher risk of poorer health status, increased psychological distress, and reduced life satisfaction, and these risks should be acknowledged by healthcare professionals.
