A typical aspirin dose for heart disease prevention is generally 81 milligrams (mg) daily, according to the American Heart Association [1]. This dose, also known as a "baby" or "low-dose" aspirin, has been found to reduce the risk of heart attacks and strokes in people who have already had one or are at high risk for heart disease [1][2]. However, it's important to note that aspirin therapy is not recommended for everyone, and individuals should consult with their healthcare provider before starting a daily aspirin regimen [1][2].

In some cases, higher doses of aspirin (325 mg) may be prescribed for short-term use after a heart attack or surgery [1]. However, long-term use of higher doses of aspirin has not been shown to provide additional benefits for heart disease prevention and may increase the risk of bleeding and other side effects [1][2].

It's also important to note that aspirin therapy is not without risks, and individuals should be aware of the potential side effects, including stomach ulcers, bleeding, and allergic reactions [1][2].

In summary, a typical aspirin dose for heart disease prevention is 81 mg daily, but individuals should consult with their healthcare provider before starting a daily aspirin regimen. Higher doses of aspirin may be prescribed for short-term use after a heart attack or surgery, but long-term use of higher doses has not been shown to provide additional benefits and may increase the risk of side effects.
