Cardiovascular Diseases: Investigating the Risk Factors and Clinical Features Using Multi-omics Technologies

This is a non-interventional case-control study aimed at identifying the genetic markers associated with various ASCVD types or with the protective effect against them. Participants are being recruited at the National Medical Research Center for Cardiology of the Ministry of Health of Russia. The study will comprise at least 10,000 participants, 1 non-ASCVD patient per 2 ASCVD patients. The recruitment period started in September 2021 and will continue till December 2023. The study will be conducted for 29 months. Observation will be carried out throughout the study.

The participants of this study will be selected from the patients of the inpatient treatment at the National Medical Research Center of Cardiology. This study procedures will have no effect on the diagnostic and therapeutic procedures implemented by the attending physicians, based on the protocols and recommendations adopted in the Russian Federation.

All participants will be divided into 2 groups:

1. Patients with severe atherosclerosis (≥ 50% stenosis caused by atherosclerotic plaque) of various vascular beds (coronary vessels, carotid arteries, mesenteric arteries, lower extremities, and kidneys)
2. Control group without clinically significant atherosclerotic lesions (≤49% stenosis).

In each group, the known risk factors and the genetic determinants of ASCVD will be investigated. Based on the results of the analysis of all factors under consideration, the study should yield a panel of ASCVD markers.
