About this study

Official title: Evaluation of Frailty, Physical Capacity and Lung Function in Postoperative Pulmonary Endarterectomy Patients: an Observational and Prospective Clinical Study

The goal of this observational and prospective study is to investigate changes in physical performance, lung function, respiratory and peripheral muscle strength in patients during the postoperative period following pulmonary endarterectomy (PET).

Read the detailed description

This study aims to investigate the physical changes in patients undergoing pulmonary endarterectomy (PET). It will observe alterations in physical performance, lung function, and muscle strength during the postoperative period. This study, observational and prospective, will include individuals aged ≥18 scheduled, evaluating them preoperatively, post-intensive care unit discharge, before hospital discharge and after six months . Assessments involve tests like the Six-minute walk test, Short Physical Performance Battery, One-minute sit-to-stand test, manovacuometry, dynamometry, spirometry and Clinical Frailty Scale to identify frailty and measure muscle and lung function. The study also aims to explore predictive variables for functional loss during hospitalization.

What is being measured

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

  1. To investigate changes in physical performance measured by Six-Minute Walk Test.

    Measures: the assessment will take place in a flat 30-meter corridor, marked every 1 meter with non-slip flooring, and the patient will be instructed to walk for six minutes as fast as possible.

    Measured: Baseline (one day before the surgery), after the surgery (the day immediately ICU discharge), before the hospital discharge (an average of 20 days) and 6 months after the surgery.

  2. To investigate changes in physical performance measured by Short Physical Performance Battery (SPPB).

    Measure: global score

    Measured: Baseline (one day before the surgery), after the surgery (the day immediately after ICU discharge), before the hospital discharge (an average of 20 days) and 6 months after surgery.

  3. To investigate changes in physical performance by 1-minute sit-to-stand test (1-MSTST).

    Measure: number of 1-MSTST repetitions.

    Measured: Baseline (one day before the surgery), after the surgery (the day immediately ICU discharge), before the hospital discharge (an average of 20 days) and 6 months after the surgery

  4. To investigate changes in peripheral muscle strength.

    Measure: hand grip strengh (Kgf).

    Measured: Baseline (one day before the surgery), after the surgery (the day immediately ICU discharge), before the hospital discharge (an average of 20 days) and 6 months after the surgery

  5. To investigate changes in respiratory muscle strength:

    Measures: manovacuometry (cmH2O)

    Measured: Baseline (one day before the surgery), after the surgery (the day immediately ICU discharge), before the hospital discharge (an average of 20 days) and 6 months after the surgery

  6. To investigate changes in lung function test measure by spirometry:

    Measured: Baseline (one day before the surgery), after the surgery (the day immediately ICU discharge), before the hospital discharge (an average of 20 days) and 6 months after the surgery

  7. To investigate frailty by Clinical Frailty Scale (CFS)

    The minimal value is 1 and the maximal is 9 in which the lowest scores mean worse outcomes.

    Measured: Baseline (one day before the surgery), after the surgery (the day immediately ICU discharge), before the hospital discharge (an average of 20 days) and 6 months after the surgery

Secondary outcomes (2)
  1. To explore potential preoperative and immediate postoperative risk factors as predictors of functional loss.

    Measures: Occurrence of comorbidities and clinical variables associated with functional decline.

    Measured: Baseline (one day before the surgery) during the immediate postoperative period.

  2. To investigate changes in hemodynamic and respiratory variables during the funcional tests.

    Measured: Immediateley before and after each functional test.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Thromboembolic Pulmonary Hypertension and Physical Disability, run by University of Sao Paulo General Hospital at 1 site in Brazil.

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 4 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 22 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Rafael M Ianotti, PT (+55 11 26615319, rafael.ianotti@hc.fm.usp.br), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To investigate changes in physical performance measured by Six-Minute Walk Test. (time frame: Baseline (one day before the surgery), after the surgery (the day immediately ICU discharge), before the hospital discharge (an average of 20 days) and 6 months after the surgery.). The study lists 7 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jun 2026.
