Normally we concentrate on the 14-35 year old age range but in this instance we also want to hear from anyone who has suffered the loss of a child under 14 years of age due to a cardiac condition and, at the other end of the scale, we want to hear of anyone aged 50 or under who has died from a cardiac condition. This will enable comparisons with other studies which use different age ranges. It will also enable comparisons with other causes of death and the different ways studies report incidence rates.
