A brief mindfulness based intervention for increase in emotional well-being and quality of life in percutaneous coronary intervention (PCI) patients: the MindfulHeart randomized controlled trial.
Study Goal
The researchers aimed to examine the effects of a brief mindfulness-based stress reduction intervention on psychological and social quality of life, anxiety, depression, and perceived stress in cardiac patients who underwent percutaneous coronary intervention (PCI).
Results Summary
The group mindfulness intervention showed larger improvements in psychological and social quality of life compared to self-help, with effects on anxiety, depression, and perceived stress evident only in patients younger than 60. These effects were partially or fully mediated by increased mindfulness.
Population
Cardiac patients (mean age 55 ± 7 years, 18% women) who had a PCI.
Effective Dosage
4-session mindfulness group intervention.
Duration
Not explicitly stated, but implied to be brief (4 sessions).
Interactions
None mentioned

a 4-session mindfulness group intervention | increase | psychological quality of life | cardiac patients who had a percutaneous coronary intervention (PCI) | partial η(2) = .04 | showed larger increases | #1 |
a 4-session mindfulness group intervention | increase | social quality of life | cardiac patients who had a percutaneous coronary intervention (PCI) | partial η(2) = .05 | showed larger increases | #2 |
a 4-session mindfulness group intervention | decrease | symptoms of anxiety and depression | patients younger than 60 years | partial η(2) = .10 | this effect was evident | #3 |
a 4-session mindfulness group intervention | decrease | perceived stress | patients younger than 60 years | partial η(2) = .15 | this effect was evident | #4 |
a 4-session mindfulness group intervention | increase | general psychosocial quality of life | cardiac PCI patients | - | seems beneficial | #5 |
In this study effects of a brief mindfulness-based stress reduction intervention were examined in cardiac patients who had a percutaneous coronary intervention (PCI). One-hundred-and-fourteen patients (mean age 55 ± 7 years, 18 % women) were randomly assigned to a 4-session mindfulness group intervention or a minimal mindfulness self-help control group that received a booklet containing identical information. Compared to self-help, the group intervention showed larger increases in psychological and social quality of life (p < .05, partial η(2) = .04 and .05, respectively). For symptoms of anxiety and depression, and for perceived stress, this effect was evident only in patients younger than 60 years (p < .01, partial η(2) = .10 and .15, respectively). These effects were partially or fully mediated by increase in mindfulness. The brief group mindfulness intervention seems beneficial for cardiac PCI patients regarding general psychosocial quality of life, although for specific psychological symptoms, this intervention can be recommended only for nonelderly patients.
