Differences in the Effect of Giving Acetylsalicylic Acid Doses of 100 mg and 300 mg to Platelet Aggregation Functions, D-Dimer Levels, and Functional Outcomes in Patients with Acute Ischemic Stroke

Acute Ischemic Stroke: A Medical Emergency Requiring Immediate Attention

Acute ischemic stroke is a medical emergency that occurs when the blood supply to the brain is disrupted, causing damage to brain tissue and potentially leading to various disabilities. According to the World Health Organization (WHO), approximately 15 million people worldwide suffer from stroke each year, with 5 million of these cases being fatal. The economic burden of stroke is also significant, with an estimated annual cost of $240 billion in the United States alone. Therefore, it is essential to develop effective treatments for acute ischemic stroke to improve patient outcomes and reduce the economic burden.

The Role of Acetylsalicylic Acid in Acute Ischemic Stroke

Acetylsalicylic acid (ASA), commonly known as aspirin, is an antiplatelet drug that has been widely used to prevent the formation of thrombus in patients with acute ischemic stroke. ASA works by inhibiting the enzyme cyclooxygenase (COX), which plays a crucial role in the production of thromboxane A2, a substance that promotes platelet aggregation. By inhibiting COX, ASA reduces the production of thromboxane A2, thereby preventing platelet aggregation and reducing the risk of thrombus formation.

The Importance of Dosing in Acute Ischemic Stroke Treatment

The optimal dose of ASA for the treatment of acute ischemic stroke is a topic of ongoing debate. While some studies have suggested that a low dose of ASA (100 mg) may be sufficient to prevent platelet aggregation, others have suggested that a higher dose (300 mg) may be more effective in improving patient outcomes. This study aims to investigate the differences in the effects of giving ASA doses of 100 mg and 300 mg on platelet aggregation functions, D-dimer levels, and functional outcomes in patients with acute ischemic stroke.

Methodology

This study was conducted by involving acute ischemic stroke patients who met the inclusion and exclusion criteria. The patients were randomly divided into two groups: one group received a dose of 100 mg of ASA, while the other group received a dose of 300 mg of ASA. Platelet aggregation functions, D-dimer levels, NIHSS (National Institutes of Health Stroke Scale) scores, and MRS (Modified Rankin Scale) scores were measured on the first day, 7th day, and 20th day after treatment.

Results

The results of this study showed that there was no significant difference in platelet aggregation functions and D-dimer levels between the two groups. However, MRS scores in patients who received 300 mg of ASA showed a significant increase compared to patients who received 100 mg of ASA. This finding indicates that the administration of high doses of ASA (300 mg) in patients with acute ischemic stroke can increase functional outcomes, although it does not have a significant effect on platelet aggregation functions and D-dimer levels.

Implications of the Study

This study provides additional evidence about the benefits of using high doses of ASA in handling acute ischemic stroke. However, further research is needed to examine the long-term effects and the safety of high-dose ASA for acute ischemic stroke sufferers. Some important things that need to be considered from this study include:

  • ASA Mechanism: ASA works by inhibiting the enzyme cyclooxygenase (COX), which plays a crucial role in the production of thromboxane A2, a substance that promotes platelet aggregation.
  • Differences in Dosage: A higher dose of ASA may inhibit the production of thromboxane A2 more effectively, thereby preventing the formation of thrombus and increasing blood flow to the brain.
  • The Importance of Monitoring: Although this study shows positive results, it should be remembered that high-dose ASA can also increase the risk of bleeding. Therefore, it is essential to carry out strict monitoring in patients who receive high-dose ASA and make dose adjustments as needed.

Conclusion

In conclusion, this study highlights the importance of dosing in acute ischemic stroke treatment. While a low dose of ASA (100 mg) may be sufficient to prevent platelet aggregation, a higher dose (300 mg) may be more effective in improving patient outcomes. However, further research is needed to examine the long-term effects and the safety of high-dose ASA for acute ischemic stroke sufferers.
Frequently Asked Questions (FAQs) about Acetylsalicylic Acid (ASA) in Acute Ischemic Stroke Treatment
