Tendencias de la mortalidad por infarto agudo de miocardio y cambios en la esperanza de vida en Andalucía (1980-2014)

Introduction and objectives

Since 1980 in Andalusia, cardiovascular mortality has declined, and life expectancy at birth has increased. The objective of this paper is to explain the contribution to life expectancy at birth of changes in mortality by myocardial infarction in Andalusia from 1980 to 2014.

Methods

Ecological design in two stages: 1980-2001 and 2001-2014. Population and deaths by cause data from National Statistics Institute. We calculate age-standardized mortality rates by myocardial infarction, which are applied to joinpoint regression models to estimate moments of change and evaluate trends. We use decomposition of differences in life expectancy to calculate the contributions of mortality change to life expectancy at birth by sex and age.

Results

Decrease in mortality by myocardial infarction in Andalusia from 1980 to 2014 has supposed a rise of 0.88 years for men, and 0.49 for women in life expectancy at birth, mainly coming from ages 65+ years-old (77% for men, 93% for women), and during the period 2011-2014 (57% and 89%).

Conclusions

The decline of mortality by myocardial infarction has implied a remarkable progress in life expectancy at birth of Andalusian population.
