Novel Risk Prediction Approaches for the Primary Prevention of Cardiovascular Diseases in Italy: the CVRISK-IT Trial (CVRISK-IT)

Primary Prevention, Cardiovascular Risk, SCORE2/2-OP

The CVRISK-IT study aims to evaluate the health benefit of measuring genetic and imaging risk information in men and women considered at 'low-to-moderate' or 'high' risk of developing cardiovascular diseases (CVD) in a randomized controlled trial in Italian primary care settings. Our primary objective is to answer a fundamental question in the prevention and prediction of CVD in Italy and globally: is there any benefit in including additional information (such as genetic and/or imaging data) in estimating risk, in conjunction with lifestyle advice and medical treatment for primary prevention of CVD? As a key secondary objective of the CVRISK-IT study, the goal is to build a large bioresource with clinical information and biological samples to facilitate a new generation of discovery and translational research that will advance understanding of the genetic, molecular and behavioural determinants as well as mechanisms of multiple chronic diseases in the Italian population. By contributing to the Rete Cardiologica database and the BBDCARDIO biobank, the CVRISK-IT study will also serve as a cornerstone for future investigations into the development and testing of early diagnostic technologies and preventive (or 'personalised precision health') interventions for chronic diseases.

This multicenter, open randomized trial will investigate the effects of providing additional CVD risk information alongside personalised lifestyle advice and medical treatment in a primary prevention context across Italy. Healthy individuals aged 40 to 80 years, with no prior history of CVD or diabetes, will be recruited in two phases from the cohort of 17 participating IRCCS across Italy and affiliated enrolling centers. The population enrolled in this study consists of subjects who have never participated in other cardiovascular prevention studies of the Rete Cardiologica. Phase 1 - Identification of the study population and development of the bioresource: various recruitment sources will be used, including institutions, primary care centres/services, government agencies, occupational health services, and volunteer organizations (e.g., blood donors). Participants will provide informed consent, a blood sample, and complete an electronic questionnaire. Approximately 30,000 individuals will be recruited and assessed using SCORE2/SCORE2-OP risk prediction models. Those identified as 'very high' risk will receive immediate medical treatment and will not proceed to phase 2. Phase 2 - Randomization and novel risk prediction interventions: Participants identified as 'low-to-moderate' or 'high' CVD risk during phase 1 will be randomized, following a 2x2 factorial design into four groups within 1 week upon enrolment: a control group (no additional risk information), and three intervention groups (genetic, imaging-based and genetic + imaging-based risk information). The goal is to randomize around 12,000 participants in phase 2 (\ 3,000 per trial arm). All individuals will receive tailored lifestyle advice along with medical treatment based on their newly estimated CVD risk. The remaining 18,000 participants who won't proceed to phase 2 will still be involved in the study and contacted through a phone call follow-up with specialist at the 5◦ and 10◦ year.
