A Johns Hopkins-led study of 1,200 people with implanted defibrillators shows that within a few years, one-quarter experienced substantial improvements in heart function, reducing the risk of arrhythmia and device shocks. Improved heart function was primarily attributed to concurrent use of heart failure medications and pacemakers.

A study of 234 comatose cardiac arrest survivors found that patients with sinus bradycardia during therapeutic hypothermia had a 17% 180 day mortality rate, compared to 38% in those with no sinus bradycardia. This suggests that heart rate may be an early marker for patients who have a better chance of recovery.

A leading expert suggests that taking patients in cardiac arrest to hospital may be actively harmful and recommends empowering ambulance staff with skills to optimise CPR at the scene. This approach could save lives and reduce unnecessary transports, but experts acknowledge the complexity of applying guidelines in different regions.

A recent study led by Lund University researchers has found that therapeutic hypothermia treatment for cardiac arrest is just as effective at a body temperature of 36°C as it is at 33°C, without the increased risk of side effects. This finding has important implications for patient rehabilitation and recovery after cardiac arrest.
A multicenter clinical trial compared mechanical chest compressions with manual CPR and found that neither approach improved 4-hour survival rates.
