Objective: Mindfulness-based stress reduction (MBSR) is a structured group program that employs mindfulness meditation to alleviate suffering associated with physical, psychosomatic, and psychiatric disorders. In this study, we investigate the impact of MBSR on left ventricular (LV) and endothelial function in female patients with microvascular angina. Method: A total of 34 female patients (mean age 52.2±13.8 years) diagnosed with microvascular angina underwent a MBSR program with anti-anginal medication for 8 weeks. The global longitudinal strain (GLS) of the LV was used as a parameter to assess myocardial function and reactive brachial flow-mediated dilatation (FMD) was used to assess endothelial function. Symptoms were analyzed by the Symptom Checklist 90 Revised (SCL-90-R) to determine emotional stress. Changes in GLS and FMD between baseline and post-MBSR were analyzed.
After 8 weeks of programmed MBSR treatment, stress parameters were significantly decreased. In addition, GLS (-19.5 ± 2.1% vs -16.6 ± 2.5%, p<0.001) and reactive FMD significantly improved (8.9 ± 3.0% vs. 6.9 ± 2.6%, p=0.005) after MBSR compared to baseline. The changes in GLS correlated to changes in FMD (r = 0.120, p = 0.340) and with the changes in most stress parameters.
MBSR has beneficial impacts on myocardial and endothelial function in female patients with microvascular angina.
