Angina in children - a consequence of congenital and acquired diseases
Angina children - a rare phenomenon, however, it is found.The reason may be a variety of congenital and acquired diseases that lead to a reduction in the lumen of the coronary artery spasm, or their walls with the subsequent development of oxygen deficiency in cardiac muscle cells.
What causes angina in children
Angina - a short-term bouts of acute cardiac pain associated with oxygen starvation of cells of the heart muscle - the myocardium.Children angina occur when a mismatch between myocardial oxygen demand and delivery.
This situation may occur when the partial obstruction (obstructive) coronary (supplying the heart muscle) to background arteries congenital abnormalities or acquired diseases, as well as a significant increase in bulk (hypertrophy) of ventricular myocardium, when the increased demand for oxygen is not completely satisfied in spitethe normal patency of coronary arteries.
angina in children with congenital anomalies of the coronary arteries
Congenital anomalies of the coronary arteries do not occur so often.It manifested the disease in most cases, already early childhood.But in some cases, the first symptoms of angina in these children appear in adolescence in a period of rapid growth of all internal organs, including the heart.
most common abnormality of the coronary arteries in children is a discharge of the left coronary artery from the pulmonary trunk.At the beginning of this anomaly of the coronary artery is narrowed slit-like shape.Sometimes coronary artery runs between the aorta and the pulmonary artery - if you exercise these vessels are increasing in volume and compress the coronary artery.
angina is manifested in children with congenital anomalies more often in early infancy as angina Angina - the consequences of the activity - attacks of pain in the heart, associated with physical exertion.
children early are starting to realize that if there was a pain, you need to stand still and it will pass.Sometimes the chest pain accompanied by nausea, dizziness Dizziness - if the ground is slipping from under his feet and fainting.Occasionally such pains appear for the first time in adolescents.And since in most cases they have a coronary anomaly they know nothing, there is a risk of myocardial infarction with high physical activity (for example, in sports).
Angina children may also develop on the background of hereditary disorders of lipid metabolism - dyslipidemia, which leads to increased formation of cholesterol and atherosclerosis in childhood.These children angina develops against the background of coronary heart disease.
angina in children with acquired diseases
most often to the coronary arteries in children causes Kawasaki disease - acute systemic inflammation with necrosis in the walls of large, medium and small arteries, combined with the defeat of the skin, mucous membranes, lymph nodes and joints.
exact causes of the disease are unknown, but suggests that a genetic predisposition are important and immunity disorders.Starting torque are most often various infections.Kawasaki disease affects mainly boys under 8 years representatives of the yellow race.In our country, the disease is relatively rare.
acute Kawasaki disease begins as an acute respiratory viral infection.Then increased cervical lymph nodes Lymph nodes - what keeps our immune system , appears redness of fingers and toes, skin rashes of various kinds, dense swelling of hands and feet, joint pain Joint pain - how to understand what is going on? , diarrhea.On examination, the doctor finds an increase in the size of the heart and liver.High temperatures can hold up to a month.The recovery period may last up to several months or even several years.
a result of Kawasaki disease may develop various pathologies of the coronary arteries, including aneurysm (areas of sharp expansion of the arteries), stenosis (narrowing of the areas), thrombosis (blood clots can partially or completely block the coronary arteries).All this may lead to the development of chronic ischemia (oxygen deficiency) the myocardium.Complication of Kawasaki disease are myocardial infarction and coronary artery rupture.
Angina children may develop also at a magnification of ventricular volume, such as congenital heart disease or high blood pressure, the presence of severe kidney disease.In this case, an increase in the amount of myocardium is not enough oxygen, which he delivered normal coronary arteries.
Finally, angina, children may develop on the background of frequent palpitations (tachycardia) caused by a variety of diseases.
angina treatment in children is carried out after a thorough examination and identification of the causes of pain in the heart.
