Hypothesis
What is the level of knowledge of modifiable risk factors for heart disease among patients with acute myocardial infarction?
Conclusion
Only 42% of patients admitted with acute myocardial infarction in Pakistan had a good level of knowledge about modifiable risk factors for heart disease.
Supporting Evidence
- Only 42% of the study population had a good level of knowledge about heart disease risk factors.
- 96% of participants could identify at least one risk factor for heart disease.
- Only 20% of participants correctly identified all four modifiable risk factors.
Takeaway
Most people who had a heart attack didn't know enough about what causes heart disease, like eating unhealthy foods or not exercising.
Methodology
A cross-sectional study was conducted using a structured questionnaire to assess knowledge of risk factors among patients with their first acute myocardial infarction.
Potential Biases
Recall bias may underestimate knowledge, and the study design does not allow for determining knowledge prior to the event.
Limitations
The study relied on self-reported knowledge, which may lead to overestimation, and the questionnaire has not been validated.
