1. What is rheumatic heart disease?
Rheumatic heart disease is an autoimmune inflammatory disease that occurs after a bacterial infection of the oropharynx. The causative organism is group A hemolytic streptococci. Within 2 to 3 weeks of oropharyngeal streptococcal infection, if not adequately treated, the disease can progress to rheumatic fever. Rheumatic heart disease is most common between the ages of 5 and 15, although it can occur in younger children and adults as well. The prevalence of the disease in boys and girls is the same.Rheumatic heart disease will become dangerous if not treated in time. Rheumatic heart disease can cause serious complications in the brain, heart, joints, skin. In the heart, rheumatic fever leaves long-term consequences such as inflammation of the heart, thickening of the heart valves. Over time, it will lead to heart valve damage, heart failure, arrhythmia, stroke, and even death.

Clinical pharyngitis : Common before 1-2 weeks. Body as a whole: Patient has low fever or high fever; whole body fatigue, poor eating; possible cough, chest pain... Valve inflammation: Common new apical systolic murmur due to mitral regurgitation; mid-apical diastolic murmur (carey coomb), possibly due to increased T3 pitch; diastolic murmur at the base of the heart due to aortic regurgitation. Myocarditis : The heart rate is usually tachycardic, corresponding to an increase of 1 degree C – heart rate increases 30 to 35 beats/min Pericarditis : Blurry heart sounds, pericardial rub can be heard Arthritis : Common Common in small joints or large joints such as: Knees, ankles, elbows, wrists... joints are painful to move, limited movement, swollen-hot-red. Characteristics of arthritis: Responds very quickly to salicylates, when cured without leaving sequelae, without treatment, it also resolves itself after 4 weeks.

Ban disappeared after a few days. Meynet granules: These are floating particles under the skin with a diameter of about 5-10 mm, sticking to the bone base (elbows, knees...) and painless, appearing with arthritis and heart inflammation, disappearing after a few weeks. Heart failure (in case of severe rheumatic fever): The patient has difficulty breathing, dry cough, edema, enlarged liver, distended neck veins, moist rales in the lungs... ; increased fibrinemia; Protein C increased; Antistreptolysin O (ASLO): Elevated > 200 Todd units. Increases after infection with group A beta-hemolytic streptococci after 2 weeks, lasts for 3-5 weeks and then gradually decreases. Electrocardiogram: Grade I atrial-ventricular block is common. Sinus tachycardia. Atrial extrasystoles, ventricular extrasystoles... Cardiopulmonary : Can see enlarged heart, dark hilum...

Although there are many dangerous complications, but basically rheumatic heart disease can be prevented through the following measures:Always keep the living environment, clean the body, especially the nose and throat area regularly and clean. Keep the neck, chest, nose and throat warm in winter and eat enough nutrients to improve resistance. If the child has a sore throat, tonsillitis or sinusitis, it is necessary to take the child to a medical facility with an ear, nose and throat specialist for thorough treatment. When you see children aged 5-15 with sore throat many times, they have pain, swelling, redness in the joints, fatigue, chest tightness, shortness of breath or palpitations, pain in the heart area, or unusual symptoms. In terms of psychomotor problems, the hand dances and plays uncontrollably, it is necessary for the child to go to the doctor immediately for timely detection and treatment and prevention of rheumatic heart disease. When children have indications for vaccination, it is necessary to follow to prevent recurrence of rheumatic fever under the guidance of doctors.
