Aspirin is an effective tool for controlling blood pressure and preventing heart attacks. But what is the optimal dose of aspirin to prevent heart attacks? According to the United States Preventive Services Task Force, 81 milligrams of aspirin a day should not be taken as a primary prevention for heart disease, except by those who have a high risk of the condition. However, it is important to note that aspirin is also an NSAID, which means it can raise your blood pressure if you have a condition that already has elevated levels.
Aspirin is a salicylate. Nonsteroidal anti-inflammatory drugs like aspirin are used for a wide range of purposes. Patients who have a higher risk of developing a heart attack are often prescribed low-dose aspirin. However, if a patient suspects that he or she is having a heart attack, the doctor may recommend a higher dose of aspirin, such as 325 mg a day. Aspirin has a 24-hour “half-life” – this means that it is strongest in the morning and weakest in the evening.
The benefits of aspirin use have been well documented. Aspirin lowers the risk of heart attacks in people with coronary artery disease and other high-risk factors. In adults with a normal blood pressure, a low dose of aspirin should be sufficient to prevent a heart attack. Those at increased risk for heart attack should take an additional 325 mg aspirin when they suspect that they may be experiencing a heart attack. Nevertheless, people with a history of high blood pressure should avoid starting a low-dose of aspirin because of the risks associated with taking this non-steroidal anti-inflammatory drug.
