Colds are minor, but they are not simple. It is true that cold is not a big disease, can be caused by a variety of viral infections, the vast majority of patients about a week or so since the cure, usually not easy to attract people’s attention. Nowadays, many big hospitals have canceled the general outpatient infusion, and it is rare to see cold and flu infusion become rare in big hospitals. However, colds can sometimes become the “tiger” that hurts people’s names and can really kill them, especially children and the weak, and colds can easily lead to viral myocarditis, which can seriously lead to the patient’s death. So, do you still think that colds are very simple? How is a cold “sad”? As we all know, most colds are caused by viral attacks. Among the cold-causing viruses, Coxsackie virus and Echovirus have a strong affinity for human heart muscle, which can easily lead to viral myocarditis. Therefore, parents should pay attention to it. When children’s resistance drops, intestinal viruses will “take advantage of the situation” and induce viral myocarditis. This disease is also associated with malnutrition, fatigue, trauma and exposure to toxic substances. What are the signs of viral myocarditis? In the early stages of the disease, children with myocarditis often have symptoms such as fever, cough, sore throat, runny nose, general malaise, nausea, vomiting, abdominal pain, diarrhea, which do not last long, followed by symptoms of cardiac anomalies, such as a rapid or slow heartbeat, stoppage of the heartbeat, irregular heartbeat. The child is depressed, has no energy and sweats profusely, loses appetite, and is prone to nausea and vomiting. In the case of small infants, they may have a white color, blue lips, weak breastfeeding, and a depressed spirit. The simplest check parents can do is to feel the child’s pulse. Generally in a quiet state, the heart rate of infants does not exceed 140 beats per minute, the heart rate of preschool children does not exceed 120 beats per minute, and school-age children are basically the same as adults. It is normal for a child’s heart rate to rise a little when he or she has a fever. However, if the fever subsides and the child’s heart rate is still faster or significantly slower than normal when the child is quiet, you should be alert to myocarditis. At this time, go to the hospital for examination, may be found to have an enlarged heart, myocardial damage, the electrocardiogram may show arrhythmia, blood tests may have elevated blood sedimentation, elevated glutamine transaminase activity, cardiac muscle antibody positive results. The most serious consequence of viral myocarditis is the myocardial damage after arrhythmia and myocardial contractility decline, the heart no longer works properly, once the heart stops beating, the body’s various functions are disorganized, the major organs stop working, the patient is facing a life-threatening situation! How to prevent “heartbreak” after a cold? It is difficult to predict whether viral myocarditis is likely to occur after a cold. The only way to prevent it is to prevent the cold itself. When you don’t have a cold, you can also maintain some good habits to minimize the incidence of the disease. Children should eat a balanced diet, not picky or partiality, often participate in physical exercise, improve the body’s ability to resist disease, often open windows to ventilate the room, keep the air fresh, in the cold season, to minimize the number of people to go to crowded places, once the virus is found after the infection should pay attention to adequate rest, to avoid over-fatigue, and timely access to medical care. Is there any hope after a cold “heartbreak”? As viral myocarditis is more insidious, many people at this time may mistakenly think that it is because the cold is not completely cured, which is easy to delay the treatment. At present, there is no specific treatment for viral myocarditis, and most acute patients are self-cured, while a few who develop into subacute or even chronic need to be hospitalized. Once the diagnosis has been made, it is necessary to take bed rest as soon as possible, avoiding strenuous activities, if there is no good rest, some may leave a variety of cardiac complications. Treatment can choose interferon inotropic injection, anti-viral treatment, and at the same time can be used in conjunction with the use of nutritive drugs for myocardial treatment. It is worth noting that the rehabilitation care of viral myocarditis, must pay attention to several points: 1, rest: arrhythmia, bed rest for 2 to 4 weeks; with heart enlargement rest for half a year to a year. Avoid overwork, hypoxia, malnutrition, respiratory infections, cold, alcoholism and other triggers. Diet: high protein, high vitamin, nutritious and easy-to-digest diet, such as lotus seed, jujube, yam, cinnamon, turtle, beef and mutton, egg and milk, porridge, etc.; small amount of meals, avoid overfilling and avoid stimulating beverages and food; low-salt diet for those with heart failure. 3, adhere to drug treatment, regular follow-up, and timely medical treatment when the condition changes. Although viral myocarditis is terrible, but as long as we can recognize early, active treatment, under the condition of modern medical technology, as with other viral infectious diseases, most of them can be completely cured.
