This study checks if a medicine called milvexian is better than a placebo (a pill with no medicine) in helping people who had a recent heart problem. It adds to regular treatments to see if it can lower the risk of serious heart troubles like heart attacks or strokes. People can join if they had a heart issue within 7 days, like a heart attack or chest pain, and have high heart test numbers.

Participants must have at least two risk factors like being 65 or older, diabetes, or past heart problems. Women who can have babies must test negative for pregnancy. People with some heart surgeries planned soon or who need certain blood-thinning medicines can't join.

• Duration: The study lasts until 4 days after the last dose of milvexian.
• Visits: Participants will have to visit the clinic for check-ups.
• Risks: Some people might experience bleeding problems.

Consider these points to decide if this study is right for you. Always consult with your doctor before participating.
