Key result
Although over 90% of physicians recommended low-dose aspirin post-MI, patient noncompliance was high (29% in Europe, 35% in Latin America), significantly affected by therapy type and physician contact (P<0.00001).

p-value: p=<0.00001
Physicians report high recommendation rates for post-MI aspirin but recognize substantial patient noncompliance, suggesting shared decision-making may improve adherence.
Substantial post-MI aspirin noncompliance despite recommendations may reflect modifiable factors; leaves open optimal adherence strategies.
Few surveys have assessed physicians' attitudes toward preventive treatment in post-myocardial infarction (MI) patients, although these patients have a high risk of recurrence. A newly developed online survey, which aimed to determine physicians' attitudes toward aspirin prophylaxis post-MI, was sent to physicians in 18 countries. This report describes findings from 7 European (n = 2842 respondents) and 2 Latin American (n = 149 respondents) countries. Although low-dose aspirin therapy was recommended by most physicians (> 90%), compliance was suboptimal; 29% of patients in Europe and 35% in Latin America were partially or totally noncompliant, and 18% of physicians in Europe and 20% in Latin America had lost contact with their patients. Low-dose aspirin monotherapy or combination therapy, dosage, and physician contact all had a significant effect on compliance (P < 0.00001). Shared decision making by the physician and patient was rated as the most effective measure to improve compliance, which clearly indicates the need for a change in management.

Zaninelli et al. (2009) conducted a cross-sectional in Post-myocardial infarction (n=2,991). Low-dose aspirin therapy was evaluated on Patient compliance with low-dose aspirin therapy (p=<0.00001). Although over 90% of physicians recommended low-dose aspirin post-MI, patient noncompliance was high (29% in Europe, 35% in Latin America), significantly affected by therapy type and physician contact (P<0.00001).
