Trial summary

Cardiovascular diseases, especially acute myocardial infarction (AMI), represent the major cause of mortality and morbidity in the world. The myocardial ischemia is often the precipitating cause of pulmonary edema and noninvasive ventilation (NIV) with positive pressure has been used as a therapeutic modality.

About this study

Official title: Non Invasive Ventilation in Acute Myocardial Infarction

Cardiovascular diseases, especially acute myocardial infarction (AMI), represent the major cause of mortality and morbidity in the world. The myocardial ischemia is often the precipitating cause of pulmonary edema and noninvasive ventilation (NIV) with positive pressure has been used as a therapeutic modality.

Objective: to evaluate the effects of NIV on heart rate variability (HRV) and on ventilatory and hemodynamic variables in patients with myocardial infarction.

Read more

Materials and methods: ten patients with acute myocardial infarction, with Killip I classification, will use continuous positive airway pressure (CPAP) and Bilevel ventilation during 30 minutes, according randomization. Then ventilatory and hemodynamic variables will be registered and electrocardiogram signals will be recorded for posterior analyses of HRV. Data will be collected before, during and after positive pressure ventilation.

Statistical Analysis: Data will be compared using One Way Anova Repeated Measures, followed by Tukey test.

Read the detailed description

The patients will be recruited in Bonsucesso Federal Hospital with diagnosis of myocardial infarction, confirmed by electrocardiogram and cardiac enzymes, between 24 and 72 hours after the event.

Participation in the study protocol will be done according to eligibility criteria:

The study will be a randomized and crossover clinical trial for evaluation and comparison of heart rate variability and ventilatory and hemodynamics variables during ventilation with CPAP and Bilevel.

CPAP will be applied via a facial mask, with expiratory positive airway pressure of 10 cmH2O. Bilevel will be applied via facial mask, with inspiratory positive pressure (IPAP) of 20 cmH2O and expiratory positive airway pressure (EPAP) of 10 cmH2O.

Being tested
BILEVEL (Respironics), Continuos positive airway pressure (Respironics)
Keywords
noninvasive ventilation, autonomic nervous system

What participants receive

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

  • BILEVEL (Respironics)Device

    Also called BIPAP

    Bilevel was delivered by a Bipap® ventilator (Respironics Inc, Murrysville, PA), applied via facial mask, with inspiratory positive pressure (IPAP) of 20 cmH2O and expiratory positive airway pressure (EPAP) of 10 cmH2O.

  • Continuos positive airway pressure (Respironics)Device

    Also called CPAP

    CPAP was delivered by a ventilator (Respironics Inc, Murrysville, PA), applied via a facial mask, with expiratory positive airway pressure of 10 cmH2O.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BILEVEL (Respironics) and Continuos positive airway pressure (Respironics) in people with Acute Myocardial Infarction, run by Centro Universitário Augusto Motta.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Dec 2011. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

evaluate HRV during NIV after acute myocardial infarction (time frame: six months). 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2011.
