Primary Outcome Measures:
  • The rate of Acute Myocardial Infarction

Secondary Outcome Measures:
  • Rate of endotracheal intubation
  • Mortality
  • Time of recovery (i.e. duration of ventilatory assistance)
  • High Dependency Unit and hospital length of stay

Estimated Enrollment: 60
Study Start Date: July 2002
Study Completion Date: May 2005
Detailed Description:

Objective: To determine whether the application of non-invasive intermittent positive pressure ventilation (n-IPPV) increases the incidence of acute myocardial infarction (AMI) in patients with acute respiratory failure (ARF) secondary to acute cardiogenic pulmonary edema (ACPE), as opposed to non-invasive continuous positive airway pressure (n-CPAP).

Background Both n-CPAP or n-IPPV are used to treat ACPE complicated by ARF. Two previous studies, however, report an increased rate of AMI associated with the use of n-IPPV.

Methods: Fifty-two patients with severe ARF consequent to ACPE were randomized to receive n-CPAP (n=27) or n-IPPV (n=25), both associated with standard medical therapy. Cardiac markers, electrocardiogram and clinical-physiological parameters were monitored at study entry, after 30 and 60 minutes, and every 6 hours for the first two days.
