Trial summary

Among patients awaiting cardiac surgery, a significant proportion are patients with severe angina, heart failure (HF) and peripheral atherosclerosis. These factors are predictors of an unfavorable near and long-term prognosis after open cardiac surgery. Read more about this study

About this study

Among patients awaiting cardiac surgery, a significant proportion are patients with severe angina, heart failure (HF) and peripheral atherosclerosis. These factors are predictors of an unfavorable near and long-term prognosis after open cardiac surgery. It is known that the restriction of motor activity in patients with peripheral atherosclerosis and HF leads to loss of muscle mass, as well as to a decrease in its strength and endurance: secondary (disuse) sarcopenia is formed. In patients with peripheral atherosclerosis and HF, the low functional status of skeletal muscles is associated with a poor prognosis, regardless of gender, age, and concomitant coronary artery disease. A number of studies have shown that the deterioration of muscle status before abdominal, orthopedic and vascular surgery interferes with the close results of surgery, increases the number of complications, the length of ICU and in-hospital stay. Thus, sarcopenia serves as an additional factor worsening the prognosis. Therefore, efforts aimed at improving the functional status in patients planning an open cardiosurgical surgery seem to be very justified.

Standard preoperative management of patients includes the identification and correction of comorbidities and the optimal medical treatment. The idea of "rehabilitation" means an additional improvement in the functional capabilities of patients awaiting surgery. Prevention includes outpatient outreach and educational work by nurses, as well as preoperative physical exercises. For this, multi-level training is used: respiratory exercises for the patients with the most severe illness, free movements of the limbs without load, or bike or treadmill training with increasing load for tolerable patients.

However, adequate physical rehabilitation is difficult particularly on an outpatient basis. Low adherence is due in part to inadequate strength and inability to tolerate or sustain even low levels of activity due to angina, chronic lower limb ischemia and heart failure symptoms.

In this study, the investigators propose to use neuromuscular electrical stimulation (NMES) to assist patient initiation of quadriceps strengthening in order to progressively increase low exercise tolerance.

Being tested
Neuromuscular electrical stimulation (NMES), Transcutaneous electrical stimulation

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Neuromuscular electrical stimulation (NMES)Device

    NMES will carried out with four-channel myostimulator "Beurer EM80" (Germany). Self-adhesive electrodes locates above the quadriceps, the duration of the NMES session was 60 minutes, including 5-minute periods of heating and hitch. Throughout the series, rectangular pulses with a frequency of 45 Hz will modulate. As a result, tonic contraction of these muscles will induce for 12 seconds, followed by a pause of 5 seconds. The amplitude of electrical exposure will select separately for each of the four channels until good muscle contraction (visually or by palpation) without pain. Electrical stimulation will start from the second day after the admission to preoperative department and will carried out during the entire preoperative period (about 10 days).

  • Transcutaneous electrical stimulationDevice

    For the Sham group, electrodes will follow the same site, but the stimulation will only increase to an intermittent tingling sensation with the machine setting on TENS instead of NMES which is not enough to make noticeable changes in muscle mass or circulation. Intensity settings will not change over time.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in strength test (Dynamometer) from baseline to post EMS in EMS vs. controls

    Strength Assessment using a portable hand-held dynamometer (Lafayette Manual Muscle Test System 001165)

    Measured: From baseline to post EMS (at least 6th day after baseline)

  2. Change in strength test (Dynamometer) from post EMS to pre-discharge in EMS vs. controls

    Strength Assessment will be done using a portable hand-held dynamometer (Lafayette Manual Muscle Test System 001165).

    Measured: from post EMS (at least 6th day after baseline) to the end of hospitalisation (expected an average of 10 days)

Secondary outcomes (2)
  1. Change in 6-minute walk test distance from baseline to post EMS in EMS vs. controls

    Participants will be instructed to move as quickly as they feel safe and comfortable over the 50-meter course for 6 minutes. As per the protocol, participants will be allowed to stop and rest if necessary

    Measured: Baseline, post EMS (at least 6th day after baseline)

  2. Change in 6-minute walk test distance from post EMS to pre-discharge in EMS vs. controls

    Participants will be instructed to move as quickly as they feel safe and comfortable over the 50-meter course for 6 minutes. As per the protocol, participants will be allowed to stop and rest if necessary

    Measured: Baseline, post EMS (at least 6th day after baseline)

Model description
This is a single-blinded, randomized controlled longitudinal study design to determine if NMES will increase muscle mass and strength and improve exercise capacity thus improving likelihood of engagement with a structured exercise program. Patients will be randomized to either intervention that includes NMES or to a sham control group. In order to ensure that the two groups are comparable between treatment and sham interventions, the participants will be randomized according to gender. Randomization via minimization will be used in order to avoid an unbalanced number of women in the two comparison groups due to chance. A file of the computer-generated random assignments will be kept.

Questions about this trial

What is this clinical trial studying?

A study testing Neuromuscular electrical stimulation (NMES) and Transcutaneous electrical stimulation in people with Sarcopenia and Exercise Intolerance, run by Research Institute for Complex Problems of Cardiovascular Diseases, Russia at 1 site in Russia.

What does the primary outcome measure?

Change in strength test (Dynamometer) from baseline to post EMS in EMS vs. controls (time frame: From baseline to post EMS (at least 6th day after baseline)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
