*Estimated from the exponential of the beta-coefficient for calendar year from age-adjusted Poisson regression models.
†P<0.001 from p value for interaction for country*year (from Poisson regression model for between-country comparison of age-adjusted trends).
‡Acute coronary syndrome comprises myocardial infarction+unstable angina; chronic CHD comprises stable angina+other CHD.
