FIELD: medicine, cardiology. SUBSTANCE: method includes two-fold estimation of maximal rate of left ventricle filling at the state of rest and at the level of dosed physical load at achieving its threshold power value, and also the gain of left ventricle volume at the phases of quick and slow filling at the state of rest, and determination of K coefficient by a certain formula. At K value equal or lower 1.0 diastolic failure of left ventricle is predicted. EFFECT: higher efficiency in earlier start of treatment and choice for adequate individualized medicinal treatment for patients of such category.
