Hypertrophic cardiomyopathy (HCM) - a disease that is characterized by hypertrophy (thickening) of the walls of the left ventricle, in rarer cases - the right, while simultaneously decreasing the cavity is disturbed diastolic function, and often lead to abnormalities in heart rhythm.

Reasons of a hypertrophic cardiomyopathy

   The disease can have the congenital or acquired character. The congenital form of a hypertrophic cardiomyopathy is descended, and in its basis genetic factors lie: spontaneous mutations and anomalies which supervise function and structure of sokratitelny proteins of a myocardium.

  In cases when the illness has the acquired character, its emergence connect with spontaneous gene mutations which occur under the influence of adverse factors of the environment.

Symptoms of a hypertrophic cardiomyopathy

   For a long time the disease can not be shown, the first signs in the majority a case develop at the age of 25Ц40 years.

  Because of a considerable hypertrophy (thickening) of a myocardium, a ventricle wall (in most cases left) become dense and rigid and aren't capable to relax fully during a warm pause. As the result this department of heart normally isn't filled with blood and intra ventricular pressure increases - these two factors become the reason of that considerably the smaller amount of blood jumps out of it at the time of warm reduction.

  The disease starts itself showing at first at big, and later and at smaller physical activities.

  In order that the organism could cope with any loadings, blood emission from heart has to increase to deliver oxygen to bodies and fabrics in necessary quantity. At a hypertrophic cardiomyopathy and at rest heart it is insufficiently filled with blood, and in the course of the increased physical activity because of increase in frequency of warm reductions filling even more worsens, i.e. heart adequately doesn't cope with the pump function.

  Loading increases intra ventricular pressure, it causes pressure growth in the left auricle, and then and in vessels of a small (pulmonary) circle of blood circulation. As the result develops short wind which amplifies in proportion to degree of physical activity, and also stenocardia (a painful attack in the middle and in the left half of a thorax). In a row cases brain blood supply that brings to faints worsens.

  To reduce intra ventricular pressure in the course of loading, the compensatory mechanism in an organism joins and develops: the cavity of the left auricle extends and its walls are thickened. However as the reserve of the left auricle as pump isn't so great, also it soon refuses.

  Expansion of a cavity of the left auricle provokes vibrating arrhythmia. The following interruptions in heart work can be observed: paroksizmalny tachycardias, fibrillation of auricles, supraventricular and ventricular ekstrasistoliya. Sometimes arrhythmias to be accompanied by faints, and in certain cases lead to a sudden lethal outcome.

  The lowered tensile properties of cavities of heart can become the reason of formation of blood clots. And movement on a blood-groove of fragments of these blood clots (tromboemboliya) provokes heart attacks of bodies and obstruction of vessels.

Diagnostics of a hypertrophic cardiomyopathy in Israel

  At cardiomyopathy diagnostics the doctor carries out collecting the anamnesis (clinical record) and fizikalny inspection. Survey of the patient reveals expansion of borders of heart, noise of different intensity.

  In addition, such methods of diagnostics of a hypertrophic cardiomyopathy in Israel, as can be applied:

  1. Rentgenografiya of a thorax Ч x-ray research which reveals increase in the left ventricle of heart.
  2. The electrocardiography (electrocardiogram) investigates activity of heart by means of record of the electric currents arising in the course of work of heart.
  3. Echocardiography Ч the main method of diagnostics of a hypertrophic cardiomyopathy which finds a thickening of a cardiac muscle, an interventricular partition, decrease in physical activity of a myocardium.
  4. The analysis of blood is defined by the possible prime causes of a cardiomyopathy.
  5. The biopsy of heart is applied in certain cases, take a sample of tissue of a myocardium for research.

Treatment of a hypertrophic cardiomyopathy in Israel

   Treatment of a hypertrophic cardiomyopathy in Israel possible in two ways: medicamentous and surgical, the main orientation - to reduce symptoms from cardiovascular system.

  Medicamentous treatment in Israel assumes application of beta-blockers and verapamil. These preparations are appointed as at treatment of already arisen and diagnosed disease, and at identification of a hypertrophic cardiomyopathy with an asymptomatic current. When this method of therapy is inefficient, recommend surgical treatment on removal of part of a hypertrophied cardiac muscle.

   The surgery carries the name a mayoektomiya, is carried out on open heart within 3-5 hours. Gosptalizatsy takes about 7 days: 1-2 days in office of intensive therapy and 4-5 days in cardiac office. The period of full rehabilitation makes 4-8 weeks.

   In comparison with other types of cardiomyopathies the forecast at a hypertrophic cardiomyopathy is favorable. Pregnancy and childbirth at women with this disease are possible. However it is important to remember that considerable physical activities are contraindicated to the patient.
