Brief Summary

In postmenopausal women, cardiovascular risk is increased and the mechanisms involving imbalance of the Autonomic Nervous System should be extensively investigated. Recent data suggest a link with intestinal microbiota dysbiosis and probiotic supplementation could be a useful strategy for treating women with increased cardiovascular risk.

Outcome Measures

Primary Outcomes (1)

  • Autonomic Nervous System

    The data will be collected through the system of acquisition of pressure waves in a continuous and non-invasive way by the Finometer® system, through a cuffing installed in the middle finger, taking this signal to an analog-to-digital signal converter. The pulse pressure signal will be acquired at 1000 Hz, continuously and non-invasively, supine (10 minutes) in a quiet environment, with controlled temperature (± 23 ° C) and illumination. The collected data will be saved in the software BeatsScope® and LabChart®, from which will be extracted the syistograms for analysis. The autonomic nervous system will be assessed at baseline and after 3 months of intervention.

    3 months

Study Arms (2)

Experimental: Probiotic supplementation

EXPERIMENTAL

The probiotic is composed of the combination of Lactobacillus acidophilus and Bifidobacterium lactis, at the concentration of 109 CFU. This product presents no known hazards associated with its use. On the contrary, the use of this supplement is associated with a rebalancing of the intestinal microbiota with potential secondary benefits to the reconstitution of the intestinal symbiosis. Patients will receive 1 sachet of 1 gram per day and will be advised to dilute in 100 mL in water at room temperature for administration.

Dietary Supplement: Probiotic supplementation

Placebo comparator

PLACEBO COMPARATOR

The placebo that will be used in the present study is maltodextrin, which is a food supplement based on carbohydrate powder.
