Bichat Hospital is launching a study to understand the reasons for sudden death in adults. But by the way, what is sudden death in adults? How many people are concerned? Can we avoid them?
Sudden death is the sudden death of a person who is obviously healthy, with no accidental cause. It is often the manifestation of unsuspected heart problems and occurs a few minutes to an hour after the first symptoms. It can reach a person in physical exertion, or at a family meal, a work meeting, or in the supermarket queue. The sudden death of a person is often a trauma to loved ones, to the extent that it occurs with brutality without one expecting it.
47% of sudden deaths are of cardiac origin. The majority of these are pulmonary embolisms, massive infarcts, an explosion or infection of the aorta (the great vessel that starts from the heart). In 28% of cases, it is heart rhythm disorders: either the heart goes too fast, or it is racing completely. One third of the victims are under 55 years old. In France, between 40,000 and 50,000 people die in these dramatic conditions each year, or about 130 deaths each day. In 5% of cases, or 2,500 of them, the causes of sudden death remain unknown.
Bichat launches a study
Funded by the Heart and Research Foundation, a study conducted by Antoine Leenhardt, a cardiologist at Bichat Hospital in Paris, will follow 50 adults who survived sudden death for two years. This new initiative baptized "And if your heart stopped beating?" was born from the discovery, by researchers at the Salpêtrière Hospital, that "an abnormality of a protein in the heart muscle" could be the cause of sudden death. "It had never been found before," says the professor in Paris. The latter will try to discover if the 50 participants have this gene. Similarly, researchers will introduce this famous protein anomaly into the genome of rats and observe if their hearts get racing.
The actions that save
70% of cardiac arrests occur in front of witnesses and barely 20% make the saving gestures. Worse, 65% of French people do not know what the first aid is. Dramatic statistics when we know that 80% of survivors are thanks to a witness who did the right thing within 3 minutes. Indeed, beyond 3 minutes without a heart massage, the brain lesions are irreversible. After 4 minutes, defibrillation has no effect.
Automatic defibrillators are beginning to take place in many public places. The French Cardiopulmonary Resuscitation Council (CFRC) collaborates with the Public Access Defibrillation (PAD) Program, set up by the Ministry of Health by Decree 2007- 705 of May 4, 2007: "Any person, not even doctor, is authorized to use an external automated defibrillator answering the characteristics defined in the article R.6311-14". As pointed out the site first-aid-and-co.fr, solutions of geolocalisation were also put in place to geolocate the nearest apparatus.
Sudden death in infants
Typically occurring before the age of 6 months, Sudden Infant Death Syndrome (SIDS) is the unexpected death of an apparently healthy infant during sleep. It could also have a genetic origin according to a study published March 28 in the scientific journal The Lancet. Led by Professor Michael Hanna of the Center for Neuromuscular Diseases at University College London, the researchers found that a rare genetic mutation could potentially be involved in sudden infant death.
However, the researchers insist, this genetic mutation alone can not explain all cases of sudden infant death. Also it is necessary to respect the recommendations of the professionals to avoid any drama. It is therefore recommended to put your child on his back in a bed with a firm mattress, not to use a pillow or duvet, but to prefer a sleeping bag adapted to the season and not to heat the room too much: its temperature must be between 18 and 20 ° C. Also beware of stuffed animals and bed rolls: babies can stick and choke on them. Also avoid sleeping on your stomach, on the side, in a sofa, an adult bed or an armchair.
