FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to pulmonology, cardiology and respiratory sleep medicine. The number of points on the Epfort sleepiness scale and the minimum night saturation are determined. In this case, each feature has its numerical value, followed by calculation by the formula, that is, each feature is assigned an experimentally established weight value in the form of a product of a constant coefficient and the numerical value of a clinical and instrumental feature: (0.71132) and the number of points on the Epfort sleepiness scale (points) (E); (-0.44202) and minimum night saturation (%) (S); and adds up to a constant equal to (22.09396). Then the calculation of the probability is performed using the original formula. With a probability value of 50% or higher, the risk of left ventricular diastolic dysfunction (LVDD) in a patient with apnea-hypopnea with subsequent development of cardiovascular complications is predicted. If the probability is below 50%, the risk of LVDD development in a patient with apnea-hypopnea is low.
EFFECT: method allows determining with high accuracy and sensitivity the likelihood of developing LVDV in a patient with apnea-hypopnea by a limited number of clinical signs.
