Innovative Research Aims to Prevent Heart Attacks in At-Risk Individuals
Every year, approximately 8,000 individuals under the age of 70 experience their first heart attack, with more than 1,000 of those cases resulting in death. In a bid to address this alarming statistic, Göran Bergström, Chief Physician at Sahlgrenska University Hospital in Gothenburg, emphasizes the importance of early detection and intervention. Bergström is also the scientific lead behind SCAPIS, the world's largest heart study, a groundbreaking initiative that aims to redefine how we approach heart and lung health.
The SCAPIS study involves a collaboration between six universities and university hospitals in Sweden, examining 30,000 residents to identify those at significant risk of heart and lung diseases. "My focus is to try to identify perfectly healthy people who walk around without symptoms but have a high risk of having a heart attack, without them even knowing it," Bergström explains.
The study's preliminary findings are concerning: over 40% of the individuals examined have shown changes in the heart's blood vessels that suggest a risk of heart attack. While most of these changes are minimal, one in 20 participants exhibited significant alterations that went undetected until now.
The next step for researchers is to develop more cost-effective methods for identifying at-risk individuals. Bergström mentions the potential of a simple blood test that could revolutionize the detection process. "If we find them, we can provide preventive help so they don't suffer a heart attack. It largely involves making lifestyle changes, but there are also fantastic medications. We have many aids for people living with risk, but first, we must find those individuals," he states.
With the goal of reducing the incidence of heart disease, Bergström envisions a future where a simple and inexpensive screening method can identify high-risk individuals effectively. "What could be revolutionary is if we find simple ways to identify high-risk individuals. Perhaps we can measure something in the blood, which becomes a rather inexpensive test. If SCAPIS leads to some form of screening method that is smart and cost-effective, I would aim for it to eliminate 20-30% of those at risk," he elaborates.
However, conducting a study of SCAPIS’ magnitude comes with significant financial demands. The Heart-Lung Foundation stands as the primary financier of this extensive research, with every contribution crucial to the ongoing efforts. Despite the scope of what they can measure in blood samples, limitations exist due to funding constraints. "We can measure a multitude of things in the blood of these individuals, but we still cannot afford to measure everything we want to measure. I think that soon ideas for a solution will come, and funding is what enables us to take that step," Bergström concludes.
As this vital research progresses, the opportunity to make a significant impact on the prevention of heart attacks is within reach. By supporting initiatives like SCAPIS, individuals can contribute to saving lives and improving heart health for future generations.
