What researchers measure

Primary outcomes

  1. Differences in carotid-femoral pulse wave velocity [m/s] in short and long-term postoperative period.

    Measurements will be performed in routine visits in Transplant Centre.

    Time frame: 1 day

Secondary outcomes

  1. Differences in central aortic pressure [mmHg] in short and long-term postoperative period.

    Measurements will be performed in routine visits in Transplant Centre.

    Time frame: 1 day

  2. Differences in central aortic pressure [mmHg] and cuff blood pressure [mmHg] in short and long-term postoperative period.

    Measurements will be performed in routine visits in Transplant Centre.

    Time frame: 1 day

The record gives a start of May 2015, a primary completion of Sep 2015 and a completion of Sep 2015. It does not say whether these dates are actual or estimated.

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 Oct 2, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
