The goal of this interventional is to assess advantages of the ultrasound examination of the lungs in the early postoperative period in cardiac surgical patients after heart surgeries requiring cardiopulmonary bypass. Evaluation of pulmonary complications and outcomes during mid-term follow-up, as well as comparison of ultrasound examination and traditional roentgenologic methods (X-ray examination and CT of the chest) will be performed. The main question\[s\] it aims to answer are: * Is ultrasound examination of the lungs a more specific and sensitive method in identification of early postoperative pulmonary complications after on-pump cardiac surgical procedures, in comparison with traditional X-ray methods. * Does early identification of interstitial pulmonary edema (based on number of visualised B-lines in the early postoperative period), influences mid-term outcomes in this cohort of patients Participants will undergo ultrasound examination of the lungs on postoperative day 1, 3, 5 and 7 after heart surgery. Based on ultrasound findings and degree of interstitial pulmonary edema, medical (diuretics, anti-inflammatory, e.t.c) therapy will be modified. Researchers will compare this group of patients with control group, in which ultrasound examination will be performed in the same time frames, but no changes in medical management based on ultrasound findings will be made to see if timely administered medical therapy, based on ultrasound findings, can significantly improve symptoms, hospital lengths of stay and outcomes of this patients.

Saint Petersburg State University Clinic
Saint Petersburg, Sankt-Peterburg, Russia
RECRUITINGThe number of participants with interstitial pulmonary edema at the day of hospital discharge, according to ultrasound lung examination
Participants with more than three B-lines according to ultrasound lung examination (BLUE protocol) at the day of hospital discharge
Time frame: Ultrasound lung examination every second day of hospital stay; from date of admission until hospital discharge or date of death from any cause, whichever came first, assessed up to 4 weeks
Postoperative pulmonary complications
Presence of any pulmonary complications (e.g. pleural effusion, pneumothorax, pulmonary edema, atelectasis, pneumonia) during postoperative hospital period will be analyzed
Time frame: Ultrasound lung examination every second day of hospital stay; from date of admission until hospital discharge or date of death from any cause, whichever came first, assessed up to 4 weeks
Cumulative dosage of diuretics
Cumulative dosage of administered diuretic drugs will be calculated for each patient in both groups
Time frame: Ultrasound lung examination every second day of hospital stay; from date of admission until hospital discharge or date of death from any cause, whichever came first, assessed up to 4 weeks
Number of nights at home after hospital discharge
During 30 days after hospital discharge, the number of nights at home without any additional medical aid due to pulmonary complications, will be found for each patient
Time frame: Ultrasound lung examination every second day of hospital stay; from date of admission until hospital discharge or date of death from any cause, whichever came first, assessed up to 4 weeks
