Key result
High social class linked to improved functional status one year post-MI versus lower classes.
Why the study?
Social class has been associated with cardiovascular illness and death, but its independent effect on functional recovery after myocardial infarction had not been examined.
Does high social class improve functional recovery in men after myocardial infarction?
Population
2145 men aged 29 to 69 years hospitalized with acute myocardial infarction
Comparison
High social class vs low or middle social class
Design
Multicenter randomized double-blind clinical trial analysis
Follow-up
12 months

High social class was associated with better post-MI functional recovery; leaves open whether socioeconomic factors are causal or modifiable.

Does high social class improve functional recovery in men after myocardial infarction?
High social class is independently associated with improved functional recovery one year after myocardial infarction in men.
Jeannette R. Ickovics (1997) conducted an RCT in Acute myocardial infarction (n=2,145). High social class vs. Low or middle social class was evaluated on Change in New York Heart Association functional class between baseline assessment and 12 months after infarction, dichotomized as improved or not improved. High social class was significantly associated with improved functional status 1 year after myocardial infarction compared to low or middle social class.
