Background: Coronary artery disease (CAD) is a major public health concern worldwide, and psychological stress is an important risk factor for CAD. MBSR, or mindfulness-based stress reduction, is showing promise as a non-medication intervention for stress management and cardiovascular health. This research aimed to evaluate the impacts of an MBSR program on cardiovascular performance in patients with CAD.

Methods: Baghdad Teaching Hospital in Iraq hosted a randomized controlled trial with 120 CAD patients. Participants were randomly placed into an MBSR group (n=60) or a control group (n=60) receiving standard care. Over eight weeks, the MBSR program participants engaged in weekly 2.5-hour sessions, incorporating mindfulness meditation, yoga, and body awareness techniques. Cardiac function was assessed using echocardiography and blood pressure measurements at baseline and post-intervention. Psychological well-being was evaluated using self-report questionnaires.

Results: A significantly greater increase in left ventricular ejection fraction (LVEF) was observed among participants in the MBSR group when measured against the control group, with a between-group difference of 3.9 percentage points (95% CI: 1.5 to 6.3, P = 0.002) at post-intervention. Significant declines in both diastolic blood pressure (DBP) and systolic blood pressure (SBP) were also observed in the MBSR group, with between-group differences of -3.8 mmHg (95% CI: -6.8 to -0.8, P = 0.013), and -4.6 mmHg (95% CI: -9.2 to -0.1, P = 0.047) respectively. Changes in psychological well-being were significantly correlated with changes in cardiac function in the MBSR group.

Conclusion: Engaging in an 8-week MBSR course can improve cardiac function and psychological well-being in patients with CAD. These findings suggest that incorporating MBSR into standard care for CAD patients may benefit cardiovascular health and stress management. Given the high burden of CAD in Iraq and other low- and middle-income countries, MBSR may represent a promising, culturally acceptable, and scalable intervention for the prevention and management of CAD. More investigation is necessary to explore the long-term effects and mechanisms of MBSR in diverse healthcare settings and populations.
