FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to pulmonology, cardiology and respiratory sleep medicine. As clinical and instrumental signs in the patient, the apnea-hypopnea index (events per hour) (A), the number of points on the Epfort sleepiness scale (points) (E), the minimum night saturation (%) (S), the time at saturation less than 90 % (% of total sleep time) (T), age in years (Ag), body mass index (B), neck circumference (cm) (O), waist circumference (cm) (O1). In this case, each feature is assigned 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: (-0.054296) and an index of apnea-hypopnea (events per hour) (A); (0.76900) and the number of points on the Epfort sleepiness scale (points) (E); (-0.51665) and minimum night saturation (%) (S); (0.072513) and saturation time less than 90% (% of total sleep time) (T); (0.050280) and age (Ag); (0.27099) and body mass index (B); (0.17566) and neck circumference (O); (-0.014849) and waist circumference (O1) and summed up with a constant equal to (9.45427). Then the probability is calculated 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 developing LVDD in a patient with apnea-hypopnea is low.
EFFECT: method allows determining with high sensitivity and specificity the likelihood of LVDV in a patient with apnea-hypopnea by a limited number of clinical signs.
