According to the Life Times, a study published in the international medical journal Circulation shows that 2.4 to 4.1 out of every 1,000 patients hospitalized for neocoronavirus develop acute myocarditis. New crown virus may induce myocarditis through the following three ways: direct damage to myocardial cells by the virus; migration of inflammatory cells to myocardial cells and induction of local inflammation; and damage to the myocardium due to systemic inflammation that triggers over-activation of the autoimmune system.
The myocardium is a muscular tissue composed of cardiomyocytes, which are the functional basis of the heart’s autonomic activity. Myocarditis is a limited or diffuse inflammatory lesion of the myocardium, which occurs mostly in winter and spring. According to the cause of myocarditis, it can be divided into two categories: infectious myocarditis and non-infectious myocarditis.
Infectious myocarditis is caused by viruses, bacteria, fungi, protozoa, parasites, spirochetes, rickettsiae, worms and other infections. Viral myocarditis is more common in daily life. Non-infectious myocarditis mainly refers to allergic or allergic reactive myocarditis, including the symptoms of myocarditis caused by rheumatic diseases, drugs, physical and chemical factors, and so on.
The chief physician of Tianjin Medical University General Hospital said that once the following symptoms appear, you should be alert to whether you are suffering from myocarditis.
Doctors say that there is little difference between the initial symptoms of the common cold and viral myocarditis, but if chest pain occurs on top of that, it means that the virus may have invaded the heart, and you need to be extra careful at this point.
Myocarditis attack, the heart’s contraction ability has been weakened, a lot of blood back to the heart, will be stagnant in the pulmonary circulation, the patient will appear chest tightness and shortness of breath symptoms.
If the heartbeat is too fast or too slow also need to pay attention to, the normal heartbeat is 60 to 100 times per minute, if the number of heartbeats per minute is always more than 100 or less than 60 times, we should pay attention to the cold is not affecting the heart.
Because the virus invades the heart, the contraction function of the heart decreases, making it unable to effectively supply the blood circulation of the body, which will cause ischemia and lack of oxygen in the whole body, resulting in the patient feeling extremely tired.
Damage to the heart muscle may lead to a drop in blood pressure, and low blood pressure may lead to dizziness, fainting or even shock in the patient.
Severe myocarditis or fulminant myocarditis will damage multiple organ systems. Some patients may experience symptoms such as renal stasis and oliguria, which indicate that the condition has become more serious.
