Nearly 400 people across the region were trained in emergency life-saving skills during 2013.
East Midlands Ambulance Service has provided training to 369 people during 30 sessions over the last 12 months.
The course, an initiative co-ordinated by the British Heart Foundation, teaches members of the public what to do in a life-threatening emergency – simple, easy-to-learn skills that save lives.
It includes how to recognise a heart attack, how to do cardiopulmonary resuscitation, dealing with choking, serious bleeding and an unconscious casualty.
Ambulance service membership manager Annie Palmer organised the course and taught the life-saving skills.
She said: “Everyone has a role to play in an emergency and giving first aid within the first few minutes of an incident can genuinely mean the difference between life and death.”
Annie has also trained 170 people in healthy-living awareness, discussing the modifications people can make to their lifestyles to help their heart.
