Key result
Regular aspirin intake was associated with a significantly lower risk of non-fatal acute myocardial infarction compared to non-use (RR 0.53).

Does regular aspirin intake prevent non-fatal myocardial infarction?
Relative Risk: 0.53 (95% CI 0.33–0.84)
p-value: p=0.02
Regular aspirin intake is associated with a reduced risk of non-fatal myocardial infarction, generating a hypothesis that requires confirmation in randomized clinical trials.
A 1974 study conducted a case-control in Acute myocardial infarction (n=14,674). Regular aspirin intake vs. No regular aspirin intake was evaluated on Non-fatal acute myocardial infarction (RR 0.53, 95% CI 0.33-0.84, p=0.02). Regular aspirin intake was associated with a significantly lower risk of non-fatal acute myocardial infarction compared to non-use (RR 0.53).
