The Effects of Mindfulness-Based Stress Reduction on Cardiac Patients' Blood Pressure, Perceived Stress, and Anger: A Single-Blind Randomized Controlled Trial

J Am Soc Hypertens. 2016 Oct;10(10):763-771. doi: 10.1016/j.jash.2016.07.007. Epub 2016 Aug 4.


This study aimed at assessing the effects of mindfulness-based stress reduction (MBSR) on cardiac patients' blood pressure (BP), perceived stress, and anger. In total, 60 cardiac patients were recruited between April and June 2015 from a specialized private cardiac clinic located in Kashan, Iran. Patients were allocated to the intervention and control groups. Patients in the experimental group received MBSR in eight 2.5-hour sessions, while patients in the control group received no psychological therapy. The main outcomes were BP, perceived stress, and anger. Analysis of covariance revealed a significant difference between the study groups regarding the posttest values of systolic BP, perceived stress, and anger (P < .001). However, the study groups did not differ significantly in terms of diastolic BP (P = .061; P = .17). This study reveals that MBSR is effective in reducing cardiac patients' systolic BP, perceived stress, and anger.
