Global CHD and stroke mortality decreased substantially between 1980 and 2010, though mortality remains significantly higher in men than women, particularly for CHD in middle age.
BACKGROUND: Cardiovascular disease mortality rates are well known to be lower in women than men and to increase with age. Whether these sex and age effects have changed over recent decades, and how much they differ by country, is unclear. METHOD: From the WHO Mortality Database, we obtained age-specific and sex-specific coronary heart disease (CHD) and stroke mortality rates for the world's most populous countries with data available between 1980 and 2010. We calculated age-specific, country-specific and period-specific men-to-women CHD and stroke mortality rate ratios for 26 countries and compared the differences between and within countries over time. RESULTS: CHD and stroke mortality decreased substantially between 1980 and 2010 in most countries, in both sexes. Mostly there was an attenuation of the effect of ageing over calendar time, more so in men than in women. CHD mortality was higher in men than in women throughout adulthood, but the magnitude of the difference varied by age. Men-to-women CHD mortality rate ratios were 4-5 in middle age (30-64 years) and 2 thereafter (65-89 years). Stroke mortality was more similar between sexes, with men-to-women stroke mortality rate ratios of around 1.5-2 until old age. CONCLUSIONS: While CHD and stroke mortality rates declined considerably between 1980 and 2010 in both sexes, there was some indication for stronger age-specific reductions in CHD in men than women. Mortality from CHD and stroke remains higher among men than women until old age across a range of economically, socially and culturally diverse countries.
