Schlaganfall und Halsarterienriss erhöhen das Herzinfarktrisiko im ersten Jahr

A new study presented at the American International Stroke Conference 2024 by the Stroke Association suggests that the risk of heart attack nearly doubles in the first year following a stroke or in combination with a tear in the wall of a neck artery. However, a tear without a stroke does not seem to increase the risk of a heart attack.

„Our findings can help doctors assess and manage cardiovascular risks following these events.“

The study focused on aortic dissection, which is a tear in the wall of the aorta, and dissection of the walls of the carotid or vertebral arteries, which can lead to a stroke, known to be associated with heart attacks. The researchers analyzed health information from over 800,000 adults to assess the risk factors associated with heart attacks following these events.

After adjusting for various risk factors, the study showed that patients who experienced carotid or vertebral artery dissection without a stroke had similar heart attack risk to those in a reference group. On the other hand, patients who had a stroke, with or without carotid or vertebral artery dissection, had almost twice the risk of experiencing a heart attack within a year.

The study, however, excluded participants with recent severe head or neck injuries and controlled for various heart attack risk factors. Although the data was based on hospital admissions in New York and Florida, the results are important as these states represent a significant portion of the U.S. population and encompass diverse demographic groups. The study’s findings underscore the importance of focusing on stroke prevention in patients at high risk for stroke and heart attack.

According to the update by the American Heart Association, approximately one out of every 21 deaths in the United States in 2021 was attributed to stroke. This highlights the significance of understanding and managing cardiovascular risks associated with stroke and arterial dissection.
