Relative (per cent) decline in death rates from cardiovascular diseases by decade, sex, and age group in 20 western high-income countries. Within each age group, death rates were age-standardised using the WHO standard population. The countries are English-speaking high-income countries (Australia, Canada, Ireland, New Zealand, UK, and USA) and countries in Western Europe (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, and Switzerland). Germany was excluded because its boundaries changed during the period of display. We also have not shown data for smaller countries like Cyprus, Iceland, Luxemburg, and Malta.
