Rising Heart Attack Trends in Sweden: A Call for Action and Research Funding
There is a concerning trend regarding the increase in heart attacks among individuals in Sweden, as observed by John Pernow, a cardiologist at Karolinska University Hospital and a professor of cardiology at Karolinska Institute. Since 1991, Pernow has witnessed a shift in the patterns of heart attacks, with the previously declining incidence now plateauing. This stagnation is particularly alarming during the holiday season, where data indicates a rise in heart attacks. While research has not pinpointed the exact causes of this trend, suspected factors include heightened stress levels and increased alcohol consumption during this time.
Despite this troubling news, progress has been made in one area: the rate of recurrence among those who have already suffered a heart attack has decreased due to advances in research. Pernow advocates for a focus on early identification of those at risk. Ideally, blood tests conducted on healthy individuals could reveal biomarkers indicating an increased likelihood of experiencing heart attacks in the near future.
In a promising development, a large-scale Swedish initiative aims to confront the high mortality rates attributed to cardiovascular diseases. The initiative, known as SCAPIS (Swedish Cardiovascular Study), represents the world's largest population study on heart, vascular, and lung health, involving six universities and university hospitals. The aim is to study 30,000 Swedes in hopes of identifying and addressing diseases before they manifest. By analyzing the health changes in these individuals over time, researchers may discern patterns that precede heart attacks and cardiovascular diseases.
Pernow highlights the significance of the SCAPIS study, noting that 40 percent of the participants exhibited changes in their heart's blood vessels indicative of future heart attack risks. While most changes were minor, one in twenty individuals showed more severe signs without prior awareness. Though the process of identifying at-risk individuals through this extensive research is costly, efforts are underway to develop simpler methods, such as blood tests, which could provide a more efficient means of risk assessment.
Moreover, the study involves specific X-ray examinations to detect the presence of atherosclerosis in the blood vessels, coupled with blood sample analyses to find markers associated with the risk of heart disease. Pernow remains optimistic about the potential for identifying sensitive biomarkers that could indicate an individual's susceptibility to heart attacks.
Pernow expresses the emotional weight of encountering patients affected by heart diseases, both young and old, emphasizing the impact on those in the prime of their lives. The chronic nature of heart disease also means that individuals who have experienced a heart attack face an increased risk of future events, even after receiving treatment.
As a means to further research in this critical area, Pernow encourages public donations to facilitate ongoing studies. He emphasizes that collective contributions, even if modest, can significantly impact research endeavors. In a poignant suggestion, he proposes that instead of gifting during the Christmas season, people consider donating that money to support cardiovascular research. With the Heart-Lung Foundation backing SCAPIS, there is hope that this research could lead to innovative solutions to prevent heart attacks and other related diseases before they arise.
