September 29th is World Heart Day, and this year's theme is "Constant Rhythm". For middle-aged and elderly people, a healthy, strong, and regularly beating heart, as well as a stable vascular system, are important foundations for ensuring the quality of life in later years. Experts remind that after the autumnal equinox, the temperature difference between day and night is gradually increasing. Patients with cardiovascular diseases, especially those with low immunity, should pay more attention to "protecting the heart" and be alert to the invasion of infectious diseases. At present, the number of cardiovascular disease patients in China is about 330 million, and the incidence rate increases with age. According to Gao Ying, chief physician of the Department of Cardiovascular Medicine at Fuwai Hospital, Chinese Academy of Medical Sciences, when the temperature fluctuates greatly, the physiological regulation, vascular status, and basic disease control of the human body may be affected, which can easily trigger vascular events such as hypertension emergencies and acute myocardial infarction. In addition, in cold environments, middle-aged and elderly patients with cardiovascular disease are more prone to immune abnormalities, and infections can exacerbate the inflammatory response in the body, further interfering with the stable control of cardiovascular disease. Taking shingles, a common disease among middle-aged and elderly people, as an example, studies have shown that patients with cardiovascular disease have a 39% higher risk of developing shingles than the general population. Once the disease occurs, the pain is more severe and lasts longer, seriously affecting the patient's quality of life. Wei Aihua, chief physician of the dermatology department of Beijing Tongren Hospital affiliated to Capital Medical University, said that for patients with cardiovascular diseases, severe pain caused by herpes zoster is like a "fuse", which may lead to faster heart rate, sudden rise of blood pressure, and increased heart load; Long term pain can disrupt sleep and mood, and may also induce arrhythmia, myocardial ischemia, and even recurrent angina. While controlling underlying diseases such as blood pressure and blood lipids, enhancing immunity and preventing infections are particularly important for patients with cardiovascular diseases. ”Wei Aihua said. Cardiovascular plays an important role in the coordinated prevention and control of chronic diseases and infectious diseases. Liu Yunjie, Director of Liulitun Community Health Service Center in Chaoyang District, Beijing, introduced that Liulitun Community actively promotes the construction of specialized disease clinics, combining chronic disease prevention and infection prevention. General practitioners can directly assess the risk of infection in patients and prescribe vaccines for those who meet the conditions. Through health lectures, family doctor signings, and other services, residents can receive more coherent health management and vaccination guidance. Regarding the concerns of some patients with cardiovascular chronic diseases about vaccination, Liu Yunjie stated that patients with hypertension, coronary heart disease, and other diseases can receive vaccines during the stable period of their condition, which can help reduce the cumulative risk of infection. Residents can make an appointment for vaccination through the official account, health app and other channels of the community health service center, and family doctors will also timely remind contracted residents to carry out relevant prevention according to health records. Many experts suggested that to protect heart health, we should not only pay attention to blood pressure, blood lipids and other indicators, but also guard against the chain effects of infectious diseases. In seasons where the temperature difference between day and night increases, scientific management of chronic diseases and proactive prevention of infections are important steps towards achieving a "steady rhythm".
