Master Zhang is 70 years old and has been suffering from hypertension and angina for several years. I heard people say that going to the hospital to hang a few days to unblock the blood vessels of the drug, you can safely through the winter. So, he hung up water for three days at the community clinic, who knew that day infusion suddenly appeared in the chest tightness, shortness of breath, rapid heartbeat symptoms, was sent to the nearby hospital by his family, the doctor suspected that Master Zhang had signs of heart failure. In fact, there are not a few elderly people who want to prevent the occurrence of cardiovascular diseases through infusion, like Master Zhang, who usually used to go to the hospital before the winter cardiovascular season for intravenous infusion of some so-called blood-vitalizing, vascular drugs. The attending physician Tang Chunping of the cardiology department of Jiangsu Provincial Maternal and Child Health Hospital and Jiangsu Provincial People’s Hospital Maternal and Child Branch said that the cardiology clinic of the hospital also often has such elderly people asking for infusion, but this practice is actually doing “useless work”. First of all, the pathogenesis of cardiovascular diseases is very complex and requires long-term integrated prevention and treatment according to the cause, which cannot be prevented by one or two drugs alone in the short term. The most common risk factors include hypertension, diabetes, hyperlipidemia, smoking, etc. If these risk factors are not effectively controlled, they will easily lead to atherosclerosis, thrombosis or bleeding over time, and eventually the common stroke, angina, myocardial infarction and other diseases, and the conventional infusion cannot play as big a preventive role as imagined. Even if the infusion can have the effect of anti-thrombosis and improve circulation, it is only a short-term effect, and these effects will disappear soon after stopping the infusion. This is definitely unrealistic and unfeasible. Secondly, cardiovascular and cerebrovascular diseases usually do not develop in one or two days. Overemphasis on the preventive effect of short-term infusion often makes many elderly patients neglect the usual treatment, and many elderly patients even think that they do not need to take medication, as long as they take infusion twice a year, which is absolutely undesirable. Third, many elderly patients often have a combination of a variety of diseases, usually take more medication, if a large number of long-term input, may also increase the burden on the kidneys, increasing the risk of kidney failure. For patients with cardiac insufficiency, infusion is not advisable, because a large amount of infusion is very likely to cause heart failure, which is very dangerous. At the same time, the risks of infusion also include phlebitis and allergic reactions, especially allergic reactions, which can cause life-threatening anaphylaxis in serious cases. The prevention of cardiovascular diseases should start from the daily routine, and we need to control the risk factors that cause these diseases, instead of waiting until the problems appear before dealing with them. In addition, it is also important to maintain a healthy lifestyle, control the diet, less salt, low fat, do not smoke, less alcohol, and regular work and rest. For people who already have cardiovascular diseases such as hypertension, it is even more important to pay attention, while adhering to medication, and to go to the hospital in a timely manner when symptoms appear.
