Key result
Type-D personality affects ~71% of MI patients and is associated with lower quality of life.
Why the study?
Is Type-D personality associated with lower quality of life and a higher prevalence of myocardial infarction?

Type-D personality is highly prevalent in MI patients and is associated with significantly reduced quality of life, highlighting the importance of psychological assessment in cardiac care.
Type-D personality was associated with MI and low QoL; case-control data leaves open causal roles and any practice change.
The present study examined the association oftype-D personality (and its components) with quality of life in cardiac patients compared with healthy people. A sample of 80 patients with myocardial infarction (MI) and 70 healthy people aged 45-60 years completed the WHO quality of life brief questionnaire and the 14-item type-D personality scale. A significantly higher percentage of the MI group scored positive for type-D personality compared with healthy individuals (71% versus 33%). Significantly more MI patients had low quality of life scores than did healthy individuals (64% versus 20%). Regression analysis showed that higher scores on type-D personality had a negative impact on quality of life in MI patients and that the social inhibition component had a greater impact than negative affectivity. Psychological assessment for type-D personality may be helpful in developing health care plans.

Saeed et al. (2011) conducted a cross-sectional in Myocardial infarction (n=150). Myocardial infarction vs. Healthy individuals was evaluated on Positive for Type-D personality (p=<0.001). Myocardial infarction patients had a significantly higher prevalence of Type-D personality (71% vs 33%) and low quality of life scores (64% vs 20%) compared to healthy individuals.
