Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Development of a new comprehensive method for perioperative prevention of atrial fibrillation paroxysms in cardiac surgery patients at the hospital stage.

It is planned to recruit 70 patients who will undergo pericardial fenestration during the operation using the original technique during coronary artery bypass grafting (Patent No. 2647626 C1 Russian Federation), and will be prescribed colchicine (the drug "Colchicum-dispert") in the perioperative period in order to prevent the development of paroxysms of atrial fibrillation in the postoperative period, and 70 cardiac surgery patients operated on using the standard technique (without performing the pericardial fenestration procedure intraoperatively), receiving non-steroidal anti-inflammatory drugs in the postoperative period.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study type: observational, analytical, cohort, prospective. Purpose: development of a new comprehensive method for perioperative prevention of atrial fibrillation paroxysms in cardiac surgery patients at the hospital stage.

Objectives:

1. To assess the risk factors that influence the development of atrial fibrillation in the early postoperative period;
2. To conduct a comparative analysis of various therapy methods to reduce the risk of developing atrial fibrillation paroxysms in the early postoperative period in cardiac surgery patients.

To solve the set tasks, it is planned to conduct a cohort prospective observational study of patients with coronary artery disease who underwent coronary artery bypass grafting with cardiopulmonary bypass.

Duration of the study - 1,5 years. The observation period for patients is the hospital postoperative period after CABG.

The study is planned to include 140 patients diagnosed with coronary heart disease. The diagnosis will be established on the basis of medical records and coronary angiography. Indications for CABG surgery will be determined by a consulting cardiac surgeon in accordance with the current Clinical Guidelines of the Ministry of Health of the Russian Federation "Stable ischemic heart disease" (2020).

Patients should be over 18 years old. It is planned to recruit 70 patients who will undergo pericardial fenestration during coronary artery bypass grafting using the original technique (Patent No. 2647626 C1 Russian Federation), and will be prescribed colchicine (the drug "Colchicum-dispert") in the perioperative period in order to prevent the development of paroxysms of atrial fibrillation in the postoperative period, and 70 cardiac surgery patients operated on using the standard technique (without performing the pericardial fenestration procedure intraoperatively), receiving non-steroidal anti-inflammatory drugs in the postoperative period. Diclofenac will be used as an NSAID in the postoperative period at a daily dose of 100 mg (orally). Colchicine (trade name of the drug "Colchicum-dispert") will be prescribed in a dose of 500 micrograms 4 hours before surgery and 500 micrograms 2 times a day for 10 days after surgery. Since the drug is not registered for the prevention of atrial fibrillation in the postoperative period, its prescription will be decided by a council of doctors, including at least 3 people (head of the department, attending physician, and research physician).

Safety evaluation Since no medical studies or interventions will be carried out in addition to what the patient should receive during standard examination and treatment, participation in this study does not entail any risks and threats to the patient.

The safety endpoints of standard treatment for this disease will be analyzed. Statistical analysis Statistical analysis of data will be carried out in the STATISTICA 10 StatSoft program. Inc. 1984-2011 (USA). Quantitative values will be displayed as median and quartiles Me \[25;75\]. Comparison of quantitative characteristics between groups will be performed using the Mann-Whitney U-test. Fisher's exact test will be used to compare qualitative characteristics. Differences will be considered statistically significant at p \< 0.05.

Ethical and legal issues of the study:

The study was approved by the Biomedical Ethics Committee at Cardiology Research Institute of Tomsk National Research Medical Center.

All patients must sign an informed consent form allowing the use of information about their examination and treatment for scientific purposes with subsequent publication of materials in the open press. The study will be conducted in accordance with the current version of the Declaration of Helsinki, the provisions of the National Standard of the Russian Federation GOST R52379-2005 on Good Clinical Practice dated April 1, 2006, the Order of the Ministry of Health of the Russian Federation dated April 1, 2016 No. 200n "On approval of the rules of good clinical practice" and the provisions of Good Clinical Practice (GCP).

The procedure for informing study subjects and obtaining written consent from them will be carried out in accordance with GCP standards.
