Heart disease is a leading cause of death worldwide, with many individuals falling into an intermediate-risk category that can often be overlooked. However, scientists at the Baker Heart and Diabetes Institute and La Trobe University have developed a novel tool to refine this risk assessment.
Lipids are fats in the blood that sit in an intermediate zone where they are considered neither low nor high-risk for heart attack or stroke. Yet these lipids could potentially indicate heart disease within striking distance. The challenge lies in accurately predicting risks for those who fall within this middle group.
For decades, researchers have used traditional risk scores like the Framingham Risk Score, which categorizes individuals into high-, intermediate-, and low-risk groups based on 'good' and 'bad' cholesterol levels. These conventional methods, however, exhibit certain limitations, particularly when it comes to assessing the intermediate-risk group.
The Baker Institute and La Trobe scientists aim to overcome these shortcomings with their new detection tool, which will enable more accurate prediction of risks, thereby allowing better targeting of preventive treatments such as lifestyle changes or aggressive medical interventions if necessary.
A late diagnosis is common due to a lack of symptoms during the early stages, making treatment even more challenging when damage has already occurred. Hence, it becomes crucially important to identify potential threats beforehand so that appropriate preventive measures can be implemented in a in a timely .
In a recent paper published in the Journal of the American College of Cardiology, scientists unveiled their lipidomic risk score, wherein they leveraged lipidomics—a study involving large-scale analysis of lipids—to enhance precision in identifying potential cardiovascular problems, especially for those falling under the intermediate-risk spectrum where conventional models fail.
Professor Peter Meikle from the Baker Institute's Department of Cardiovascular Research at La Trobe University stated that clinicians can utilize this refined version integrated into routine blood tests for better prediction regarding the accumulation of dangerous plaque buildup inside arteries, indicating higher chances of heart disease.
Meikle further suggested how this approach might streamline the selection process for determining who should undergo non-invasive imaging like coronary artery calcium scoring for better heart disease prevention and management. The aim is to optimize the use of health resources, ensuring that those who require treatment get it while avoiding overtreatment of those who don't need it.
In 2023, the Australian CVD risk assessment guidelines were updated to reflect new evidence on assessing, communicating, and managing CVD risk. Professor Meikle believes that ongoing research should shape our approach towards refining risk assessment further.
He emphasizes the importance of prevention over treatment, stating, "It is far better to prevent heart disease than treat it, so that is our focus here." He envisions pushing boundaries in order to simplify things for clinicians while making optimal use of limited health resources with a goal towards improved outcomes, especially for individuals at high risk but unrecognized.
This novel tool not only holds potential for improving accuracy in predicting risks but also promises efficient resource allocation, which could ultimately lead to enhanced patient care and potentially save countless lives.
