Coronary heart disease can appear in young people as seen in epidemiological surveys and clinical cases. Although the incidence of coronary heart disease is predominantly in middle-aged and elderly people, with the improvement of people’s living standard, accelerated pace of life, high work pressure and staying up late, irregular diet and life, as well as the lack of awareness of the incidence of coronary heart disease and the lack of improvement of health concept, a trend of younger age of coronary heart disease incidence has been found. In order to avoid or reduce the early onset of coronary heart disease in young people, it is necessary to enhance the knowledge about the causes and pathogenesis of coronary heart disease. Let young people know the harm caused by unhealthy lifestyle as early as possible, change the bad habits, detect the risk factors of coronary heart disease in time, and actively give intervention treatment, which can reduce or curb the occurrence of young coronary heart disease.
