Medicines for heart attack prevention are prescribed to individuals who are at high risk of developing a heart attack or have already had one. These medicines work to lower the risk of blood clots and reduce inflammation, which can contribute to heart disease. Common medications for heart attack prevention include aspirin, beta-blockers, ACE inhibitors, and statins. It's important to consult with a healthcare provider before starting any new medication, as they can have potential side effects and may interact with other medications. Regular exercise, a healthy diet, and quitting smoking are also important lifestyle changes that can help prevent heart attacks.
