Blood pressure level and incidence of myocardial infarction among patients treated for hypertension.
Why the study?
Does achieved blood pressure level correlate with the risk of myocardial infarction in patients treated for hypertension?

Implication
Mild BP elevations may drive substantial MI risk in treated hypertension; leaves open whether achieving normotension prevents events.
Structured PICO
Does achieved blood pressure level correlate with the risk of myocardial infarction in patients treated for hypertension?
P
Population
2,854 patients treated for hypertension, comprising 718 myocardial infarction cases and 2,136 matched controls.
I
Intervention
Achieved blood pressure level (observational exposure)
C
Comparator
Lower achieved blood pressure levels / matched controls
O
Outcome
Risk of myocardial infarctionhard clinical
Achieving normotensive levels in treated hypertensive patients with uncontrolled blood pressure might prevent more than 15% of myocardial infarctions.
