High cardiac enzymes in babies are commonly found in myocarditis, which usually has no obvious symptoms if it belongs to the mild type. If it is medium-sized, there may be symptoms such as pain in the precordial area, irritability, etc. If the condition enters the heavy type, there may also be more than crying, swelling of limbs, shortness of breath and other symptoms. Symptoms of high cardiac enzymes in babies need to be determined in relation to the specific condition. If the condition is mild, the symptoms of myocarditis are usually not obvious. If it is medium-sized, the baby may have symptoms such as pain in the precordial area, chest tightness, panic, dyspnea, nausea and vomiting. If the condition has entered the heavy type, it can easily cause symptoms such as heart failure, crying, drop in blood pressure, profuse night sweating (abnormal sweating after going to sleep and stopping after waking up), shortness of breath, cardiogenic shock and even life-threatening symptoms. When you find that your baby has high cardiac enzymes, parents are advised to take your baby to a regular hospital in time.
