Do not go breaking your heart: do economic upturns really increase heart attack mortality?

Area of Science:

• Public Health
• Epidemiology
• Health Economics

Background:

• Recent literature suggests a pro-cyclical relationship between economic business cycles and mortality.
• Understanding these economic influences on cardiovascular events like acute myocardial infarction (AMI) is crucial for public health planning.

Purpose of the Study:

• To investigate the association between business cycles and the incidence, mortality, and lethality of AMI in Sweden.
• To determine if the business cycle's impact on AMI varies across different age groups and demographic factors.

Main Methods:

• Panel data analysis of 21 Swedish regions from 1987-2003.
• Estimation of the relationship between economic indicators and AMI outcomes.
• Stratification of analysis by age and demographic variables (gender, education, foreign-born status).

Main Results:

• Overall business cycle effects on AMI incidence, mortality, and lethality were found to be insignificant in Sweden.
• A significant counter-cyclical effect of business cycles on AMI was identified for individuals aged 20-49.
• Higher proportions of women, highly educated individuals, and non-foreigners were associated with decreased AMI incidence and mortality.

Conclusions:

• The pro-cyclical relationship between business cycles and mortality observed in some studies may not be universally applicable.
• Economic downturns may disproportionately affect cardiovascular health in prime working-age populations.
• Demographic factors play a significant role in modulating AMI risk and outcomes.
