This study introduces a new framework to improve cardiovascular risk assessment tools, enhancing their reliability for better clinical decision-making in predicting cardiovascular death. The novel approach shows promising results in initial patient data analysis.
Area of Science:
- Cardiology
- Medical Informatics
Background:
- Clinical guidelines advocate for cardiovascular risk assessment tools (risk scores) to predict cardiovascular death and aid decision-making.
- Current risk scores have limitations impacting their reliability in clinical settings.
- Cardiovascular disease (CVD) poses significant social and economic burdens.
Purpose of the Study:
- To present a novel framework designed to enhance existing cardiovascular risk assessment tools.
- To minimize the limitations of current risk scores and improve their clinical reliability.
- To aid in more accurate prediction of cardiovascular events.
Main Methods:
- Developed a framework combining data from multiple sources, including existing risk scores and physician input.
- Implemented a personalization scheme to group patients and identify the most suitable risk assessment tool for individual cases.
- Applied two distinct methodologies for data processing and patient stratification.
Main Results:
- Validation performed on a dataset of 460 patients with non-ST-segment elevation acute coronary syndrome.
- The proposed approaches demonstrated promising performance metrics, including sensitivity, specificity, and geometric mean.
- Specific performance metrics achieved were 78.79% sensitivity, 73.07% specificity, and 75.87% geometric mean for one approach, and 75.69%, 69.79%, and 72.71% for the other.
Conclusions:
- The developed approaches show superior performance compared to current cardiovascular disease risk scores.
- Further validation with additional datasets is recommended to substantiate these findings.
- The framework offers a potential improvement in predicting cardiovascular risk.
