Summary

This trial aims to see if giving metoprolol early after a certain type of brain bleeding (non-traumatic subarachnoid hemorrhage) has any positive effects.

Who is the study for?
This trial is for adults over 18 who have had a non-traumatic subarachnoid hemorrhage, confirmed by neuro-imaging. It's not specified here, but typically there would be more criteria about the patient's health status and possibly other factors like how recently they've had the hemorrhage.
What is being tested?
The BADCATS trial is testing whether giving metoprolol early after a brain aneurysm that caused bleeding (subarachnoid hemorrhage) can reduce heart damage and inflammation compared to a placebo.
What are the potential side effects?
Metoprolol may cause side effects such as tiredness, dizziness, cold hands and feet, or upset stomach. However, specific side effects related to this trial are not listed here.
