Study summary

Despite the advances in the treatment of acute cardiogenic pulmonary edema (ACPE), the readmissions rates and cardiovascular events remain very high. In this context, it is possible that other potential risk factors may influence the poor prognosis of the ACPE. One of these potential candidates is Obstructive Sleep Apnea(OSA). This study was designed to evaluate the impact of OSA treatment with CPAP in consecutive patients with ACPE. The primary outcome will be to evaluate the impact of CPAP on the recurrence of ACPE in the 1-year follow-up.

    Nasal Strips

    Device: Nasal Strips

Interventions

  • DeviceCPAP

    This is the standard treatment for OSA.

  • DeviceNasal Strips

    Nasal strips were commercially available in the market for supposing treat snoring and sleep apnea but no proof that this is true. Our group previously validated nasal strips as an interesting placebo.

What researchers measure

Primary outcomes

  1. Rate of ACPE recurrence

    To evaluate the effects of CPAP on the recurrence of ACPE as compared to placebo

    Time frame: 1-year

Secondary outcomes

  1. Rate of all-cause mortality

    To evaluate the effects of CPAP on the all-cause mortality as compared to placebo

    Time frame: 1-year

  2. Rate of cardiovascular mortality

    To evaluate the effects of CPAP on the cardiovascular mortality as compared to placebo

    Time frame: 1-year

  3. Number of new hospital admissions

    To evaluate the effects of CPAP on the number of new hospital admissions as compared to placebo

    Time frame: 1-year

  4. Blood pressure effects ( (mmHg)

    To evaluate the effects of CPAP on the blood pressure reduction as compared to placebo

    Time frame: 1-year

  5. Levels of BNP levels (pg/ml)

    To evaluate the effects of CPAP on the BNP levels as compared to placebo

    Time frame: 1-year

  6. Cardiac function (left ventricular ejection fraction - %)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 7, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
