Effects of Neuromuscular Electrostimulation in Patients With Acute Heart Failure

Not Applicable

Completed

• Conditions: Heart Failure
• Interventions: Device: Neuromuscular electrical stimulation

• Registration Number: NCT04310072
• Lead Sponsor: Ploesteanu Rodica Lucia

Brief Summary

The investigators evaluated the effects of neuromuscular electrical stimulation (NMES) therapy on functional capacity and oxidative stress in patients hospitalized for an episode of acute heart failure (AHF). The NMES therapy was used on top of the conventional rehabilitation program. After randomization the investigators followed the patients by measuring the evolution of functional capacity, oxidative stress and adverse events.

Detailed Description

In this program the investigators will include patients with acute heart failure (AHF) with left ventricular ejection fraction (LVEF) lower than 50%, admitted to our clinic.

Patients prior to being included in this research will sign an informed consent form in two samples, one remaining with the patient. This form will contain the study protocol, risks, potential benefits as well as assuring patients that personal data will be used strictly for research purposes. The inclusion and exclusion criteria are presented below. The patients will be randomized into two groups: neuromuscular electrostimulation (NMES) therapy and conventional rehabilitation or a conventional rehabilitation program alone (respiratory gymnastics and strength / endurance exercises in bed).

Patients will receive optimal medical therapy for AHF according to current management guidelines. Patients will complete different questionnaires (Kansas, Beck for Depression). In the first phase, patients will be given a form with questions regarding notions about heart failure and cardiovascular recovery to assess the level of knowledge about their disease.

All patients included will perform the following:

* Clinical evaluation

* ECG

* Biological samples (including NT pro BNP, CK, oxidized LDL plus standard samples)

* Cardiac ultrasound

* 6-minute walk test (6MWT) The duration of NMES therapy will be equal to the duration of hospitalization. At the time of discharge, all patients will undergo a 6MWT and biological samples (NT pro BNP and oxidized LDL) and receive a cardiac rehabilitation program that they will follow at home. They will be given advice on initiating and maintaining a healthy diet, as well as discontinuing smoking if this risk factor is identified.

There will be a telephone visit at 30 days and the investigator will note the vital status and rehospitalizations.

Arm && Interventions

Group	Intervention	Description
neuromuscular electrical stimulation group	Neuromuscular electrical stimulation	For patients who underwent NMES therapy, four electrodes (two 50/100 mm and two 50/50 mm, Compex Performance) were placed on the skin above the quadriceps muscle approximately 5 cm below the inguinal fold and 3 cm above the upper patella border. The electrical stimulation protocol consisted of electrical current at frequency of 10 Hz, 20 seconds stimulation time (time on) and 20 seconds resting time (time off) with variable intensity (until visible muscular contraction) for one hour per day until discharge (Compex).The NMES therapy was on top of conventional rehabilitation described below.

Primary Outcome Measures

Name	Time	Method
evaluate the impact of NMES therapy applied during hospitalization on the functional capacity	up to one month (30 days)	The investigators will measure 6 minute walk test at the inclusion in the trial ans at the time of discharge
evaluate the impact of NMES therapy on oxidative stress	up to one month (30 days)	The investigator will measure oxidized LDL plasmatic levels at the inclusion in the trial ans at the time of discharge
