Such scenes often appear on television, a certain role due to excessive anger and anxiety after hand over the chest, expression pain, and then vomit blood and die. The cause of death is mostly explained by only one disease – myocardial infarction. Art comes from life but higher than life, most people with real myocardial infarction will cover their chests, but certainly no one will vomit blood, today we will explain the relationship between “angry and anxious” and “coronary heart disease”! People who love to be angry and anxious have another name in the eyes of cardiologists, called “Type A personality” people. This is the division made by two good American doctors, American cardiologists Friedman and Rollinman to divide the personality of people into two types of A, B. Type A personality has the following characteristics: they are in a hurry, work at a very fast pace, have a strong sense of time urgency, competitive, and do not stop when they encounter difficulties, there is a sense of dissatisfaction with everything. Type A people are ambitious, short-tempered, competent, and outgoing. They are extremely easy to get angry and anxious, often for some small things can be angry, although career-oriented, but to the surrounding people with “hostile”. The opposite personality is the B-type personality. Shanghai Changhai Hospital Thoracic Surgery Department Xue Qing Understand the type A personality, we will talk about why type A personality people are more likely to get coronary heart disease, more likely to get myocardial infarction? Scientists’ research shows that the prevalence of coronary heart disease is several times higher in people with type A personality than type B personality. Domestic data also shows that type A personality accounts for more than 70% of the number of coronary heart disease, and most of the people who already suffer from coronary heart disease have a majority of type A personality. Friedman and Rollinman, the two Americans who invented the “personality classification”, found through extensive research on the relationship between people’s mental activities and diseases that most people suffering from heart disease are those with sharp and ambitious minds, and these people are precisely type A personalities. These people are Type A personalities. Most people with Type A personality have high expectations of themselves, so that their psychological and physical burdens are very heavy. They often hold the firm belief that “only success, not failure”, at the expense of their own everything, desperately straight to their set goals. The tension will stimulate the brain center, a large number of catecholamines and other factors to stimulate the basic metabolism into the blood, resulting in type A personality people are very vulnerable to hypertension or coronary heart disease and other diseases. Type A personalities are demanding in their work and strict in their surroundings. While working hard, the accumulation of a series of tensions will easily lead to a decline in the body’s immune function and make them susceptible to related diseases, including angina pectoris and myocardial infarction in coronary heart disease. Type A personality, due to irregular diet and work, is very likely to lead to physical exhaustion. Moreover, Type A personality can provoke special neuroendocrine mechanisms, which can cause changes in the blood lipoprotein composition and increase the average concentration of serum cholesterol and triglycerides, and lead to coronary atherosclerosis. Coronary atherosclerosis is an important pathological basis for angina pectoris and myocardial infarction. People with type A personality are in a state of long-term mental tension, which leads to constant sympathetic excitement and faster heart rate, which easily increases the blood supply load to the heart muscle, leading to aggravation or triggering of coronary heart disease and myocardial infarction in serious cases. In short, type A personality has been proven to be a good prevalence of coronary heart disease, so maintaining the right intensity of mental and physical stress is the only way to avoid disease at home.
