Key result

Only 42% of patients with a first acute myocardial infarction had a good level of knowledge of modifiable risk factors, with more than 10 years of schooling significantly predicting better knowledge (OR 2.5).

Implication

Low AMI risk-factor knowledge signals education gaps; cross-sectional data leaves open whether interventions improve outcomes.

P
Population
720 patients admitted with their first acute myocardial infarction (AMI) at a tertiary care hospital in Karachi, Pakistan, mean age 54 years.
O
Outcome
Level of knowledge of four modifiable risk factors of heart disease (fatty food consumption, smoking, obesity, and exercise), with 'good' knowledge defined as knowing three out of four.patient reported

Main Result

Effect estimate: OR 2.5 (95% CI 1.30-4.80)

A majority of patients presenting with their first AMI in Pakistan lack adequate knowledge of modifiable cardiovascular risk factors, emphasizing the need for targeted educational interventions.

Limitations

  • Level of knowledge was assessed using a structured questionnaire, which may overestimate knowledge
  • Reliance on ability to recall risk factors introduces recall bias
  • Questionnaire was not validated
  • Choice of cumulative score of 3 as 'good' knowledge is arbitrary
  • Cross-sectional design cannot determine knowledge status prior to the index event

Khan et al. (2006) conducted a cross-sectional in Acute myocardial infarction (n=720). > 10 years of schooling vs. No schooling was evaluated on Good level of knowledge of modifiable risk factors (OR 2.5, 95% CI 1.30-4.80). Only 42% of patients with a first acute myocardial infarction had a good level of knowledge of modifiable risk factors, with more than 10 years of schooling significantly predicting better knowledge (OR 2.5).
