Do not follow improvised first aid tips circulating on social media, such as coughing vigorously when experiencing a heart attack while alone, as they are dangerous; instead, prioritize calling emergency services immediately.

Julien warns here against the myth of 'cough CPR' in the event of a heart attack, and science fully supports him. The American Heart Association (AHA), in its official guidelines (expert consensus), formally advises against this practice for the general public, specifying that it is only useful in very rare hospital settings under monitoring. Similarly, the Fédération Française de Cardiologie (consensus statement) reminds us that attempting to self-resuscitate by coughing delays the only vital reflex: calling emergency services (15 or 112). No clinical or observational study validates the efficacy of this method for a person alone at home. This false tip can even unnecessarily exhaust the body during cardiac stress. Julien's alert is therefore scientifically unimpeachable and beneficial.
