Cardiovascular disease is the most common non communicable disease in the world, causing nearly 18.6 million deaths every year, accounting for 1/3 of the global death toll. The prevention and treatment of cardiovascular disease is a social problem faced by all mankind. In order to publicize the knowledge of heart health to the public, the World Heart Alliance established World Heart Day in 1999. September 29, 2022 is the 23rd World Heart Day. This year's theme is "One Heart", which is intended to advocate the public to pay more attention to, spread and practice the concept of heart health more actively and attentively. According to China cardiovascular health and disease report 2021, the incidence rate and mortality of cardiovascular diseases in China are still the highest, with 330 million cardiovascular patients and 2 deaths in every 5 deaths. The report points out that China is facing the dual pressure of aging population and the continued prevalence of metabolic risk factors, and the burden of cardiovascular disease will continue to increase. This year's World Heart Day advocates the whole life cycle health management of cardiovascular disease, and improves the public's awareness of cardiovascular health. Each of us is the first person in our own health. We should attach importance to the primary prevention of cardiovascular disease, develop a healthy lifestyle, comprehensively control cardiovascular risk factors, and prevent cardiovascular disease from the source; We will strengthen the secondary prevention of cardiovascular disease, scientifically regulate the diagnosis and treatment of cardiovascular disease, and delay the development of cardiovascular disease in the process. Developing a healthy lifestyle and moderate exercise can effectively reduce the incidence rate and mortality of cardiovascular diseases. Research shows that people who actively participate in sports have a lower risk of cardiovascular disease compared with people who are sedentary. Experts suggest that adults combine aerobic sports such as running and swimming with resistance sports such as strength and equipment sports to reduce sedentary time. At present, the widely recognized aerobic exercise program is at least 150 minutes of moderate intensity or 75 minutes of high-intensity aerobic exercise every week. Smoking is harmful to health. Quitting smoking is the most effective way to prevent cardiovascular disease. The study shows that continuous smoking is the main risk factor for adverse clinical outcomes in patients with recurrent myocardial infarction and revascularization; Most smokers have a higher risk of death caused by cardiovascular disease than lung cancer, and their cardiovascular disease may lead to sudden death at the beginning of its onset. Healthy diet can reduce the risk of cardiovascular disease. Experts suggest to adjust the diet structure, and replace the animal based diet structure with the plant based diet structure to reduce the risk of cardiovascular disease. In 2017, nearly 3 million people worldwide died of cardiovascular disease due to insufficient coarse grain intake and excessive fine grain intake. A diet based on fruits and vegetables can effectively reduce metabolic risk factors including blood pressure, blood lipids, insulin resistance, etc. Potassium salt can reduce the risk of cardiovascular disease by 13%, and reduce the risk of heart disease or stroke by 11%. Bad psychological states such as depression, anxiety, rage and mental stress are also related to cardiovascular disease. The increase of mental stress increases the risk of coronary heart disease. Depression is associated with an increased risk of cardiovascular death in adults, especially men. Experts suggest that psychological counseling and mental health care can improve the symptoms of mental stress and quality of life, and reduce the risk of cardiovascular disease. Controlling cardiovascular risk factors Long term hypertension can lead to vascular sclerosis,
