About this study

Official title: CArdiovascular Risk Assessment Via Multimodal Data Analysis Enabling Personalised Prevention Strategies Targeting MEnopausaL Women - Observational Study

CARAMEL is a project funded by the European Commission under the Horizon Europe programme. Its aim is to develop a personalized prevention approach based on state-of-the-art artificial intelligence models for cardiovascular risk stratification in women aged 40-60 years. These models are trained using large amounts of multi-source data and complemented by digital self-assessment and self-management tools. The CARAMEL consortium brings together a diverse group of 25 organizations, including technology companies and research centers, clinical institutions, as well as experts in ethics, law, and communication.

The CARAMEL-OS study is an observational study aimed at prospectively completing the proposed personalized cardiovascular risk stratification model for women aged 40-60 years that will be developed during the earlier phases of the overall CARAMEL project (https://www.caramel-project.eu/).

Read more

The study has a purely observational design, and patient stratification will not entail any clinical intervention. The data collected will be used to complete the design of the personalized stratification model, as well as to develop and validate the performance of the predictive models in an independent prospective cohort, distinct from the retrospective cohort initially used. The performance of the models developed using retrospective data will be assessed in terms of accuracy, discrimination, calibration, and other relevant metrics. In addition, the study will enable the development of new predictive models with short-term prediction horizons, incorporating additional variables that are not available retrospectively.

The study population will be recruited in four European Union countries: Croatia, Spain (Andalusia and The Basque Country - Gipuzkoa), Greece and Lithuania; and in Colombia. A prospective cohort of 3,000 women aged 40-60 will be recruited, with each partner contributing 500 participants.

Read the detailed description

A prospective observational study involving 3,000 women across six clinical sites will be conducted to generate a comprehensive multi-source dataset for the development of cardiovascular disease (CVD) risk assessment models. In addition to socioeconomic, clinical, biochemical, and imaging data, the study will use novel non-invasive technologies to collect additional potentially relevant variables, aiming to improve understanding of female-specific cardiovascular risk factors and biological changes around menopause age. By refining the CARAMEL stratification scheme based on the most effective approaches, the project aims to provide innovative tools for personalized CVD prevention and risk stratification. This ambitious and integrative approach is expected to advance precision medicine in women's cardiovascular health, support clinical decision-making, and inform future preventive strategies at both individual and population levels. Central to these strategies is the development of the datApp - a mobile application designed to serve as a personalised companion for women throughout their menopausal transition.

Study groupRoleWhat they receive
3,000 women aged 40-60 recruited in four European Union countries and Colombia.The study population will be recruited in five sites belonging to four European Union countries: Croatia, Spain (Andalusia and The Basque Country - Gipuzkoa), Greece and Lithuania; and one South America country that is Colombia. A prospective cohort of 3,000 women aged 40-60 will be recruited, with each partner contributing 500 participants.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of hypertension

    Incidence of hypertension will be assessed by measuring blood pressure during the baseline and final study visits, as well as by reviewing the diagnosis of hypertension recorded in the electronic health records. Participants enrolled during a self-monitoring month will be asked to measure their blood pressure twice daily throughout 1 month.

    Measured: From enrollment to program completion, spanning 21-24 months depending on the enrollment date.

  2. Incidence of dyslipidaemia

    Incidence of dyslipidaemia will be assessed through blood tests measuring HDL cholesterol, LDL cholesterol, total cholesterol, and triglyceride levels at the baseline and final study visits, as well as by reviewing diagnoses of dyslipidaemia recorded in the electronic health records.

    Measured: From enrollment to program completion, lasting 21-24 months depending on the enrollment date.

  3. Incidence of diabetes mellitus

    Incidence of diabetes mellitus will be assessed through blood tests measuring glomerular filtration rate, albumin-to-creatinine ratio, glucose and glycated hemoglobin levels at the baseline and final study visits, as well as by reviewing diagnoses of diabetes mellitus recorded in the electronic health records.

    Measured: From enrollment to program completion, lasting 21-24 months depending on the enrollment date.

  4. Incidence of cardiovascular disease

    The incidence of cardiovascular disease will be assessed through the diagnosis of the following conditions: myocardial infarction, chronic coronary syndrome, peripheral arterial disease, and stroke. This information will be collected through a structured medical history interview and by reviewing the electronic health records. These data will be collected during the baseline visit and the final visit.

    Measured: From enrollment to program completion, spanning 21-24 months depending on the enrollment date.

Secondary outcomes (1)
  1. Mortality of cardiovascular events.

    Mortality of cardiovascular events will be assessed through review of electronic health records, collecting information on new cardiovascular events and mortality occurring during the follow-up period and identified at the final assessment.

    Measured: From enrollment to program completion, spanning 21-24 months depending on the enrollment date.
