Several friends around Huazi had cold symptoms of fever, chills, nasal congestion, and runny nose, and asked Huazi what to do? Huazi told them that they could use antipyretic drugs, anti-allergic drugs and other drugs for symptomatic treatment, but the key to curing the cold was to rest more, and must not do strenuous exercise for two weeks.
Friends are a little puzzled, exercise can sweat, should help treat colds, why can't you exercise? Hanako said that because some "colds" are not colds, they may be dangerous fulminant myocarditis, and strenuous exercise is life-threatening.
1. Dangerous fulminant myocarditis
In the news, it is often seen that young people have sudden cardiac death during exercise, and in the aftermath investigation, many cases have "cold" experiences in the days before sudden death. But in fact, these people do not suffer from a cold, but fulminant myocarditis, but the symptoms of the initial stage of the disease are very similar to those of a cold, and it is very easy to misdiagnose.
The cause of fulminant myocarditis is adrenaline infection caused by adenovirus, influenza virus, Epstein-Barr virus, enterovirus, etc., in addition to the damage caused by the virus to the heart, there is also the "accidental injury" caused by the body's immune system overreacting to the heart. After heart damage, it will affect the blood supply function, and even cause malignant arrhythmias, resulting in sudden death.
Second, easy to misdiagnose diseases
The cause of fulminant myocarditis is a viral infection, and the prodromal symptoms include fever, fatigue, nasal congestion, runny nose, sore throat, cough, etc., and if infected with enterovirus, it can also cause diarrhea. These symptoms are very similar to common viral colds and gastrointestinal colds, and are very easy to misdiagnose.
In the days after the appearance of cold symptoms, chest tightness, chest pain, shortness of breath, palpitations and other symptoms of heart damage may occur, but the specificity of these symptoms is not high, it is difficult to arouse the patient's vigilance, especially young patients may not have particularly obvious symptoms.
However, during strenuous exercise or physical activity, the damaged heart cannot meet the body's blood supply needs, and it may cause dizziness or fainting. Severe cases can experience heart failure, shock, and even sudden death.
Adequate rest is the key to curing diseases
After the virus invades the myocardium, if the myocardial enzyme profile, electrocardiogram, cardiac ultrasound and other indicators are checked in time, abnormal cardiac function will be found.
However, if the doctor recommends that a patient with only cold symptoms do these tests, he will definitely be labeled with an overtreatment, and the vast majority of people rarely take the initiative to go to the hospital when they have cold symptoms, which leads to many patients with fulminant myocarditis who cannot be diagnosed in time.
However, the human body has an immune system that can clear the virus, and the heart damage caused by the virus is usually not very serious, as long as it is given enough time, the body will repair the damaged heart muscle. During the illness, as long as you do not force the heart to overload, there is a high probability that there will be no serious consequences.
At present, human beings do not have drugs that can directly kill the virus in the body, the treatment of viral infections, mainly for life support and symptomatic treatment, and finally solve the virus still depends on the body's own immune system, full rest is the key to curing viral infectious diseases.
Therefore, when there are cold symptoms, you must rest more, do not do strenuous exercise, and do not stay up late, you can prevent the dangers posed by fulminant myocarditis disguised as a cold.
To sum up, if you have cold symptoms, it is recommended not to do strenuous exercise for 2 weeks and beware of fulminant myocarditis. If after a cold, there are symptoms of chest tightness, chest pain, and palpitations, go to the hospital for examination and treatment in time. Medications can be used for symptomatic treatment, but medications should be used under the guidance of a doctor, and if you have any doubts about medication, please consult a doctor or pharmacist.
