Cardiac screening programmes
Some countries have players who have taken part in screening programmes to try and identify those who have a heart condition that may predispose them to having a cardiac arrest.
From a pitch side perspective, the screening programme is of little relevance as these have only been shown to reduce the incidence of sudden cardiac death and not prevent it.
Globally, cardiac screening programmes remain controversial. Those who are present pitch side still need to be aware that an on field or crowd cardiac arrest may happen and to be prepared for it in case it does.
