Oriented Magnetic Fields and Blood Pressure

Hypertension is a combination of genetic, environmental, and social factors, defined by blood pressure levels in which the benefits of treatment outweigh the risks. The global prevalence of hypertension is approximately 1.3 billion adults. The blood pressure control rates in developing countries in 2019 were 23% in women and 18% in men.

Treatments range from lifestyle modification, medication treatment, and use of medical devices. The prevalence of resistant arterial hypertension is estimated between 12% to 15% among patients with hypertension. Up to half of patients with resistant hypertension are partially or not adherent to pharmacological treatment. The World Health Organization (WHO) has identified five dimensions for treatment adherence, shown in .

Abstract

Background:

Neuromuscular electrical stimulation seems to be a promising option to intensify the rehabilitation and improve the exercise capacity of patients in the immediate postoperative period of cardiac surgery.

Objective:

This study aimed to evaluate the hemodynamic (heart rate, systolic blood pressure, diastolic blood pressure, and mean blood pressure) and respiratory (respiratory rate and oxygen saturation) responses to neuromuscular electrical stimulation in the immediate postoperative period in patients submitted to cardiac surgery and to verify its feasibility and safety.

Methods:

This is a pilot randomized controlled trial, wherein critical patients in the immediate postoperative period of cardiac surgery were randomly assigned to a control group, using sham neuromuscular electrical stimulation, or an experimental group, submitted to neuromuscular electrical stimulation sessions (FES), for 60 min, with a 50-Hz frequency, 200-µs pulse duration, time on: 3 s, and time off: 9 s. Data distribution was evaluated by the Shapiro-Wilk test. The analysis of variance was used and a p-value < 0.05 was considered significant.

Results:

Thirty patients were included in the study. The neuromuscular electrical stimulation was applied within the first 23.13 ± 5.24 h after cardiac surgery, and no changes were found regarding the hemodynamic and respiratory variables between the patients who underwent neuromuscular electrical stimulation, and those in the control group.

Conclusions:

In the present study, neuromuscular electrical stimulation did not promote changes in hemodynamic and respiratory responses of patients in the immediate postoperative period of cardiac surgery.
