Influenza vaccine not only prevents influenza, but also protects against cardiovascular and cerebrovascular diseases
In recent years, the prevalence and incidence of cardiovascular and cerebrovascular diseases in China have been increasing. It is estimated that the total number of cardiovascular and cerebrovascular disease patients in China reaches 290 million, of which 13 million suffer from stroke and 11 million from myocardial infarction. Cardiovascular diseases seriously endanger the lives and physical and mental health of everyone, causing 4 million deaths every year, accounting for more than 40% of total deaths, as well as being the key cause of disability and longevity damage.
Influenza may be the trigger for death of cardiovascular disease patients. Influenza is a subacute respiratory infection caused by the influenza virus, and if not prevented and treated immediately 疫苗注射, it can be relatively harmful to physical and mental health. Why does influenza increase the risk of death from cardiovascular disease?
1, the high quality inflammatory response caused by influenza will endanger the role of capillary endothelial cells, inhibit the left ventricle of capillaries, promote coagulation and reduce the reliability of the spots, which in turn causes cardiovascular disease things.
2、After the infection of influenza virus, there may be a variety of cardiovascular disease, such as chronic heart failure, heart disease, insufficient blood supply to the heart, stroke, which will also enhance the risk of cardiovascular disease death.
3、After the infection of influenza virus, the inflammation of the lung will endanger the respiratory system of the patient, causing the patient to suffer from poor breathing and other diseases, which will lead to the lowering of the body's O2 level, which will also aggravate the heart disease.
As we all know, the flu vaccine is a reasonable way to prevent influenza as it significantly reduces the risk of influenza and more serious morbidities in those who receive it. In recent years, many studies have shown that the flu vaccine can reduce the risk of cardiovascular death and ischemic events in heart attack patients and patients undergoing capillary repair during the flu season. As a result, the flu vaccine has been branded by some experts and scholars as a “cardiovascular vaccine”. So, how exactly does the flu vaccine produce maintenance for patients with cardiovascular disease?
1、Immediate efficacy
The antigen that occurs in the body after influenza vaccination can have an immediate effect on the oxidation of HDL in the air, which can block foam cells and reduce the generation of spots, reducing the risk of ischemic heart disease and stroke.
Some studies have shown that influenza vaccination reduces the risk of myocardial infarction in patients with a previous history of myocardial infarction. In addition, influenza is also effective in maintaining patients with heart failure.
2、Indirect effects
Influenza vaccination reduces the incidence of new coronary pneumonia, which in turn reduces the risk source of cardiovascular diseases such as ischemic heart disease and stroke, and thus this reduces the incidence of these conditions.
Some studies have shown that: patients who have been injected with influenza vaccine are less likely to have ischemic stroke than patients who have never received influenza vaccine to prevent it, and the more years of previous vaccination, the lower the risk of stroke generation.
