[Heart involvement in patients with multiple myeloma based on echocardiographic data]

An echocardiographic study of 50 patients with multiple myeloma was carried out. Disorders of the contractile and pumping function of the left ventricle myocardium, changes of the central hemodynamics were revealed. It was shown that at stage I the main functions of the heart are maintained due to myocardial hypertrophy. Progression of the disease, development of chronic renal failure and concomitant pathology of the cardiovascular system, the contractile function of the myocardium is essentially reduced, the left ventricle and left atrium is dilated. It is concluded that echocardiography allows to reveal early sings of cardiac lesions and predict development of cardiac insufficiency.
