Background and Aim Mindfulness meditation (MM) leads to controlled blood pressure and positive improvements in other symptoms which may trigger acute coronary diseases. The present randomized controlled study was aimed to investigate the effect of the MM on fatigue, kinesiophobia, and the quality of life (QoL) in patients with acute MI. Method The study was carried out with 56 MI patients. Participants were randomly assigned to meditation group (MG; n = 28) or control group (CG; n = 28). The MG patients received a 15 min MM session comprising sitting and breathing for a total of eight weeks, while the CG patients received only a single-time attention-matched education. Piper Fatigue Intervention, Tampa Scale for Kinesiophobia-Heart and MacNew Quality of Life scales were utilized for data collection. Results After completion of the 8-week MM, any significant difference was not found in the fatigue scores of the patients (p > 0.05). On the other hand, kinesiophobia scores in the MG were significantly lower in the 4th, 8th and 12th weeks (p < 0.05). Similarly, the QoL scores were significantly higher in the MG in 8th week (p < 0.05). Significant change in the emotional function sub-dimension of QoL continued in the follow-up assessment at 12th week (p < 0.05). Conclusion The MM can significantly improve the QoL and decrease kinesiophobia in patients with MI. Beneficial effect of MM is maintained particularly in the emotional aspect. Based on the results of the study, MM may be recommended as a mind-body based complementary approaches within the scope of secondary protection after MI.
