Data-Driven Models Advance Early Detection of Heart Failure Risk
Researchers have developed novel data-driven models to predict heart failure risk years before symptoms appear, offering a significant step forward in preventive cardiology. These models leverage large-scale health data to identify individuals at risk, enabling earlier intervention and potentially reducing the burden of heart failure on healthcare systems.
Understanding the SCORE2-HF Model
The first model, known as SCORE2-HF, is designed for the general population and can estimate the risk of developing heart failure over a period of up to 30 years. It relies on routinely collected health indicators such as blood pressure, body mass index, smoking status, type 2 diabetes, and the use of hypertension medication. The model’s reliability was validated using data from the Estonian Biobank, drawing on health information from nearly 700,000 individuals aged over 36 living in Estonia in 2012 through the BIG‑HEART database.

According to Laura Lõo, Junior Research Fellow of Public Health at the University of Tartu, who led the research alongside international colleagues, heart failure is often detected only when a person seeks medical care for another reason. “It is therefore crucial that treatment reaches the right people at the right time,” she stated. The models were published in the European Heart Journal and are expected to be recommended in future clinical practice guidelines by the European Society of Cardiology.
Multimodal Approaches Enhance Prognostic Accuracy
Beyond population-level risk assessment, advanced models are improving prognosis for those already diagnosed with heart failure. A multimodal data fusion approach integrates clinical data, cardiac imaging, and real-time physiological monitoring from IoT devices. This method combines graph neural networks (GNN) and convolutional neural networks (CNN) to analyze diverse data types, resulting in superior performance in predicting death events and identifying high-risk patients compared to traditional single-source models.
Tested on chest X-ray imaging and a proprietary heart failure electronic medical record dataset, the multimodal model demonstrated higher accuracy, AUC, and F1 score in validation studies. Researchers emphasize that combining imaging, clinical features, and continuous monitoring addresses the complex pathology of heart failure, which is often inadequately assessed using only one data source.
Machine Learning in Heart Failure Prognosis
Machine learning-driven models are likewise being applied to predict outcomes in patients hospitalized with heart failure. Retrospective studies using electronic health records have shown that these models can accurately forecast prognostic outcomes, supporting clinical decision-making. While specific algorithms and datasets vary, the overarching goal remains consistent: to harness data for earlier, more precise risk stratification.
The Importance of Early Prediction
Heart failure remains a leading cause of hospitalization and mortality worldwide. Early identification of at-risk individuals allows for preventative strategies such as lifestyle modifications, medication optimization, and closer monitoring. By shifting focus from reactive treatment to proactive prevention, data-driven models have the potential to improve patient outcomes and alleviate strain on healthcare infrastructure.
As validation studies continue and models are refined, experts anticipate broader implementation in clinical settings. Ongoing research supported by large international health databases and biobanks will be critical to ensuring these tools are accurate, equitable, and applicable across diverse populations.

Frequently Asked Questions
- What is heart failure?
- Heart failure is a chronic condition where the heart cannot pump blood effectively to meet the body’s needs, often resulting from underlying cardiovascular diseases.
- Can heart failure be prevented?
- While not all cases are preventable, managing risk factors such as hypertension, diabetes, obesity, and smoking can significantly reduce the likelihood of developing heart failure.
- How do data-driven models improve heart failure risk assessment?
- These models analyze large datasets to identify patterns and risk indicators that may not be apparent through traditional methods, enabling earlier and more personalized predictions.
- Are these models available for public use?
- Currently, these models are primarily used in research and clinical validation phases. Widespread availability will depend on regulatory approval and integration into healthcare systems.
