METHOD OF PREDICTION OF POSTOPERATIVE CARDIAC ISCHEMIC COMPLICATIONS IN A PATIENT WITH LUNG CANCER Russian patent published in 2023 - IPC A61B5/00 A61B5/205 A61B5/145 G01N33/49 G01N33/50 

FIELD: medicine; pediatric urology.

SUBSTANCE: sampling and clinical analysis of peripheral blood parameters of the patient in the preoperative period are carried out. Before surgery, the total blood protein, the functional class of chronic heart failure, the localization of pulmonectomy are determined, and the cardiac risk is determined according to the NSQIP perioperative risk assessment scale. The duration of the operation is also recorded. On the first day of the postoperative period, the content of leukocytes, erythrocytes, creatinine is determined in the patient's blood and the heart rate is determined, after which the values of the prognostic coefficients F₁ and F₂ are determined according to the original formulas. When F₁ value is greater than F₂ value, a high risk of developing cardiovascular complications is predicted in patients with lung cancer after surgical treatment, and when F₂ value is greater than or equal to F₁ value, a low risk is predicted.

EFFECT: method provides an individual prognosis of the development of postoperative cardiac ischemic complications in a patient with lung cancer with an accuracy of 93.29%, does not require expensive research methods due to the determination of indicators used in routine clinical practice, which makes it possible to adjust the treatment plan for the patient's preoperative preparation.
