A death data from the psychiatric hospital, from this data found that the psychiatric hospital inside the seriously ill patients, the ultimate cause of death is only one, it is not suicide, nor is it depression, but every one of our people may suffer from a disease, so what is this disease? We can see from a set of pictures, each face in this is the face of a mental patient, if we take a closer look at each of these faces, you will realize that they actually have an extremely similar expression, this expression is indifference, which we commonly called the poker face, what is even more horrifying is that this poker face has a direct relationship with their same cause of death. This is a mysterious file from a psychiatric hospital, from these files we find that the patient’s death certificate here is amazingly consistent, their cause of death is only one is myocardial infarction. How can it be that the final cause of death of patients with severe mental illness is myocardial infarction? Why is it that the cause of death in psychosis is myocardial infarction, which seems to have nothing to do with psychosis? Behind these files suggests that extreme emotions and myocardial infarction must hide an unknown relationship of death. What kind of relationship exists between heart attacks and poker faces? Twenty-four hours before the recording of the program, our Big Doctors team collected ten volunteers nationwide to participate in a real-life experiment designed by Liu Meiyan, Chief Physician of the Department of Cardiology at Anzhen Hospital, and her team. The original template for the real-life experiment came from an emergency clinical trial published in the American Journal of Emergency Medicine, in which 50 emergency patients were observed to determine their cardiovascular responses to strong stimulus images. The original template of this real-life experiment is from an emergency clinical experiment in the American Journal of Emergency Medicine. This time, a team of experts from Anzhen Hospital will ask ten volunteers to watch an emotionally stimulating video in order, including a car accident video, which will make people feel surprised and afraid, and a funny video, which will make people feel happy. A team of experts from Anzhen Hospital will monitor and record the volunteers’ facial expressions and analyze the volunteers’ cardiovascular status against the facial expression coding system to find out any possible problems. Generally, people with healthy cardiovascular status will have a nervous expression when watching these stimulation videos, however, we found that not every participant’s expression changed during the test. So we arranged for the volunteers to undergo cardiac ultrasound and neck vascular ultrasound at the Heart Center of Anzhen Hospital, in order to check the volunteers’ heart function, whether the blood flow rate of blood vessels is normal or not, and whether there are hardened plaques in the blood vessels and other problems. So what are the cardiovascular problems that can be found among us volunteers, and how can all this be linked to expressions? How can we self-test ourselves to see if our blood vessels are at risk of being triggered by bad emotions.
