Chest tightness, feeling like dying, not a heart attack or what? Is there no one who can help yourself? In fact, this is a manifestation of an anxiety disorder called panic attack. Panic attacks are one of the manifestations of anxiety disorders, also known as acute anxiety attacks, and often occur after excitement, physical exertion, sexual activity, or a severe emotional trauma, but the first attack is often spontaneous and has no apparent trigger. Activities associated with panic attacks include coffee drinking, smoking, alcohol consumption, abnormal eating or sleeping patterns, and some specific environmental stimuli (e.g., stimuli such as flashing lights in the workplace). Xiao Li is a salesman in the company, once to go out of town on a business trip, he just got off the plane and felt his heart beat faster, dizzy, cold sweat on his forehead, and nausea and vomiting, he felt as if he was going to die. “It must be a heart attack!” Xiao Li hurriedly called a car to the hospital. Looking at the trembling, white passenger, the driver was terrified and immediately took Xiao Li to the emergency room. The doctor did a series of tests such as an electrocardiogram for Xiao Li, but strangely enough, no physical disease was checked. After coming out of the hospital, Li felt like he was back to his old self, and the pain he felt before seemed like a dream. After returning home, Xiao Li still had palpitations, he paid more attention to take care of his body, not to smoke and drink, sleep on time, and go out for a half-hour run every day. Recently, Xiao Li was promoted, and work has become busy. However, he has been insisting on exercise, physical condition is also relatively good, no uncomfortable feeling. Another business trip on the way, Xiao Li again felt chest tightness and nausea, he once again went to the hospital for a comprehensive examination, the results still did not find any problems. From then on, Xiao Li was no longer willing to travel, and often even suffocated himself at home. A panic attack usually manifests itself as a sudden and intense fear of dying as if one is about to die while the patient is carrying out daily activities, such as reading a book, eating a meal, taking a walk, having a meeting or doing housework. This nervousness makes the patient unbearable. At the same time, the patient feels palpitations, as if the heart is about to jump out; chest tightness, a feeling of pressure in the anterior chest area; or difficulty in breathing, throat blockage, as if they cannot breathe and are about to die of suffocation. As a result, the patient will scream, call for help or run out of the room, clutch their heads, and some have symptoms such as hyperventilation, dizziness, facial flushing, excessive sweating, unsteady gait, tremor, numbness of hands and feet, and gastrointestinal discomfort. Such episodes, which usually last for 5-20 minutes, are short-lived and can resolve on their own. After remission, the patient feels that everything is normal, but there is a possibility of a sudden relapse soon. Most patients are often anxious during the interval after recurrent panic attacks for fear of having another attack, and may also show some symptoms of autonomic hyperactivity. Patients are often afraid that they will die because of heart or respiratory diseases; therefore, many people with panic attacks consider palpitations and precordial pain as angina attacks, and about 20% of them have syncope during the attacks. Due to the intense fear, the patient is unbearable and often immediately asks for emergency help. In the interval between attacks, 60% of patients actively avoid some activities, such as not daring to go out alone, not going to crowded places, not traveling by car, or asking for company when going out, because they are afraid of not getting help during the attack. It has been observed that panic attacks can seriously affect the patient’s functioning and are often co-morbid with other anxiety disorders, such as place phobia and obsessive-compulsive disorder. Due to the disease, patients are often unable to hold down a normal job, as well as affecting spousal relationships, etc., and the attitude of family members often has an impact on patients.
