Cardiovascular diseases annually kill half of the sick population of our planet.
Cardiology is engaged in the study of cardiovascular pathologies as well as the development of methods for their treatment and their application in practice.
Cardiological diseases are caused by pathological change in the rhythm of the heart and the conducting system; increased pressure in the coronary vessels; cardiovascular failure; extra coronary pathologies; malformations (acquired and congenital); metabolic disorder.
The causes of diseases of the cardiovascular system are most often: prolonged nervous tension (due to psychological trauma, prolonged stress or constant experiences); atherosclerosis, provoking coronary heart disease; severe blood loss. Some heart diseases can be caused by infections (for example: group A beta-hemolytic streptococci). Increasingly, the birth of children with heart defects due to intrauterine disorders is observed;
Symptoms of cardiovascular diseases are very different and only doctor, only cardiologist, can correctly determine their attitude to cardiovascular diseases.
The most common symptoms are:
-chest pain of various types.
-heart palpitations (including at rest).
-shortness of breath that appears after intense physical activity or independently.
-change in skin color (pallor, blueness)
For the diagnosis, the following methods are used:
-electrocardiography Using an ECG to determine the heart rate and frequency of its contractions Comparing with normal indicators, probability of pathology and its type can be concluded
-echocardiography. ECHO-KG is an ultrasound technique used to examine the heart and coronary vessels
-phonocardiography. With its help, sounds produced during cardiac activity are recorded in the form of a curve
-coronarography. The CAG method is relevant for the detection of coronary heart disease. For this, a conductor is introduced, following from the femoral artery to the heart under X-ray control. It produces a contrast visible under x-ray, so that existing anomalies can be noticed.
Pathologies of the cardiovascular sphere can affect a person at any age. The most common diseases of the heart and blood vessels today are:
stroke, hypertension, arrhythmia, tachycardia, angina pectoris, heart failure, myocardial infarction, arterial hypertension, cardiac arrhythmia, collapse, ischemic stroke, hypertensive crisis, extrasystole, coronary heart disease, circulatory disorders, hypertension, mitral valve prolapse, cardioma.
