A Call to Action: Understanding the Rising Trend of Heart Attacks in Sweden
There is a concerning trend emerging in Sweden regarding the increasing incidence of heart attacks. Dr. John Pernow, a cardiologist at Karolinska University Hospital since 1991 and a professor of cardiology at Karolinska Institute, highlights that after a period of decline, the number of heart attacks has plateaued and started trending upwards. Particularly troubling is the spike in heart attack cases around the holiday season, a phenomenon that remains unexplained by research. Factors such as heightened stress and increased alcohol consumption during this time might be contributing to this rise.
On a more positive note, while the overall trend of heart attacks is worrying, the statistics concerning rehospitalization rates among those who have suffered a heart attack have improved, thanks to ongoing research. Dr. Pernow emphasizes that our focus must now shift to identifying individuals at risk before they experience a heart attack.
Ideally, researchers would like to analyze blood samples from healthy individuals to pinpoint biomarkers indicative of a heightened risk of heart attacks in the near future. Dr. Pernow is hopeful that such biomarkers can be identified, providing a path to better prevention.
In an international context, one significant initiative from Sweden is making strides against the high mortality rates from cardiovascular diseases. The Swedish initiative is home to the world's largest population study on cardiorespiratory health known as SCAPIS (Swedish CardioPulmonary bioImage Study). This groundbreaking study involves six universities and university hospitals, and it aims to investigate the health of 30,000 Swedes to identify and ultimately treat diseases before they manifest.
SCAPIS represents a forward-thinking approach. By examining a large population and tracking which individuals suffer from heart attacks or other cardiovascular diseases, researchers can identify common characteristics that may indicate risk. According to Dr. Pernow, changes in heart and blood vessel health can be revealing. Alarmingly, 40% of the participants examined in the study have shown early signs, mainly mild, but 5% had significant changes without any prior indication that they were at risk.
While finding these biomarkers is resource-intensive, research is underway to develop simpler and more cost-effective testing methodologies, including blood tests that correlate to risks associated with atherosclerosis and potential heart attacks.
Dr. Pernow expresses a deep emotional response when witnessing both young and old individuals affected by these ailments. Heart attacks can have life-altering consequences, marking a transition into a chronic health condition for many survivors, who face an increased risk of subsequent heart attacks.
In terms of support for ongoing research, Dr. Pernow encourages donations to further the study of cardiovascular health. He believes that even small contributions can collectively lead to significant advancements. Particularly around the holiday season, he suggests that forgo traditional gift-giving in favor of supporting vital research initiatives like SCAPIS.
SCAPIS aims to prevent heart attacks and strokes before they occur, marking it as the largest study of its kind globally, and is significantly funded by the Heart-Lung Foundation. The collective effort in research can not only change the trajectory of heart health in Sweden but could also set a precedent for similar initiatives worldwide.
