When someone has a heart attack, doctors immediately work to prevent the next crisis, often a stroke. A key warning sign is plaque buildup in the carotid arteries in the neck, which can break off and cause a stroke. This study looked for a simpler way to spot that risk.
Researchers analyzed data from over 7,000 patients who had an acute coronary syndrome (a heart attack or unstable angina). They calculated several inflammation scores from standard blood cell counts. They found that patients who had carotid plaques had higher scores across the board. Three scores in particular—MLR, SIRI, and AISI—showed a strong, independent link to having these dangerous plaques. The link was especially clear in women and in patients without diabetes.
This was a retrospective study, meaning it looked back at existing records. While it shows a connection, it can't prove that higher inflammation causes the plaque to form. The findings point to these simple blood markers as potential tools for flagging patients who might need closer monitoring for stroke risk after a heart event. More research is needed to see if tracking these scores can actually help prevent strokes.
