About this study

We conducted a national, single center (Hospital Clínico Universitario de Valladolid, Spain, Valladolid), prospective study of patients with prior hospitalization because of COVID-19 who were admitted between March 1st, 2020, and May 15th, 2020. All eligible patients underwent at least at first-time follow-up from the index event. Exclusion criteria were age < 18 years old, pregnant women, terminally ill patients, active SARS-CoV-2 infections, inability to exercise and previous known severe pulmonary or heart disease. Patients underwent a clinical assessment for symptom burden, questionnaire for quality of life (Kansas City Cardiomyopathy Questionnaire and SF-36), venous blood sampling, 6-minute walking test (6-MWT), tests of lung function (spirometry and diffusing capacity of the lungs for carbon monoxide) and treadmill cardio-pulmonary exercise testing (CPET). 48-hours before the test of lung function and the CPET, all patients yielded a negative result in the reverse transcription-polymerase chain reaction (RT-PCR) for SARS-CoV-2. For definitive analysis patients were assigned to the control group if they did not refer dyspnea at the time of the follow-up, a small asymptomatic out-patient control group without prior hospitalization was also included.

Questions about this trial

What is this clinical trial studying?

An observational study of Covid19 and Dyspnea, run by Hospital Clínico Universitario de Valladolid at 1 site in Spain.

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 5 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 25 Oct 2021. 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 Spain. 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?

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?

Aerobic capacity (time frame: 6 months). 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?

On the ClinicalTrials.gov record for NCT04689490, which also lists 3 linked publications.

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 25 Oct 2021.
