Background: Health-related quality of life (HRQoL) is an important outcome for patients diagnosed with coronary
heart disease. This report describes predictors of physical and mental HRQoL at six months post-hospitalisation for
myocardial infarction.

Methods: Participants were myocardial infarction patients (n=430) admitted to two tertiary referral centres in Brisbane,
Australia who completed a six month coronary heart disease secondary prevention trial (ProActive Heart). Outcome
variables were HRQoL (Short Form-36) at six months, including a physical and mental summary score. Baseline
predictors included demographics and clinical variables, health behaviours, and psychosocial variables. Stepwise forward
multiple linear regression analyses were used to identify significant independent predictors of six month HRQoL.


Results: Physical HRQoL was lower in participants who: were older (p<0.001); were unemployed (p=0.03); had lower
baseline physical and mental HRQoL scores (p<0.001); had lower confidence levels in meeting sufficient physical activity
recommendations (p<0.001); had no intention to be physically active in the next six months (p<0.001); and were more
sedentary (p=0.001). Mental HRQoL was lower in participants who: were younger (p=0.01); had lower baseline mental
HRQoL (p<0.001); were more sedentary (p=0.01) were depressed (p<0.001); and had lower social support (p=0.001).


Conclusions: This study has clinical implications as identification of indicators of lower physical and mental HRQoL
outcomes for myocardial infarction patients allows for targeted counselling or coronary heart disease secondary
prevention efforts
