Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Investigators hypothesize that a risk score that incorporates non-invasive coronary CT imaging (calcium score and/or coronary CTA) in combination with clinical characteristics (classical risk prediction models) will improve the identification of patients who are at highest risk to suffer myocardial infarction or sudden cardiac death.
The overall goal of the OPeRA project is to develop, implement and validate a novel risk assessment tool based on image markers and clinical characteristics to identify patients who are at increased risk to suffer myocardial infarction or sudden cardiac death.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To develop a national coronary CTA registry with the collaboration of all major cardiac CT centers of Hungary (Országos Plaque Regiszter és Adatbázis - NatiOnal Plaque Registry and DAtabase, OPeRA).
1. To develop a novel risk assessment tool (OPeRA score) based on image markers and clinical characteristics.
2. To identify and validate novel vulnerable coronary plaque image markers and assess their prognostic value.
Secondary goals:
1. To develop a standardized and structured, national coronary CTA reporting system.
2. To establish a national quality control system that monitors the quantity of iodinated contrast agent and the patients' radiation dose.
