Hypothesis
Non-compliance is the predominant cause of aspirin resistance in chronic coronary arterial disease patients.
Conclusion
The study concludes that non-compliance is the main reason for aspirin resistance in patients.
Supporting Evidence
- 9% of patients with a history of myocardial infarction were aspirin resistant due to non-compliance.
- Only 3% of compliant subjects had a net aspirin inhibitory response of less than one standard deviation.
- Statistical analysis showed no difference in net aspirin inhibition between normal and MI subjects.
Takeaway
Some people don't take their aspirin as they should, which makes it seem like the medicine isn't working when it really is.
Methodology
The study involved measuring platelet function in patients who were either compliant or non-compliant with aspirin intake.
Potential Biases
Potential bias in self-reported compliance and the exclusion of non-compliant subjects from analysis.
Limitations
The study may not account for all factors influencing aspirin resistance, such as genetic differences.
Participant Demographics
Mean age of compliant subjects was 63 years, with 63% males and 37% females.
