Trial summary

The investigators investigated the clinical impacts of preoperative nutritional status on mortality in patients undergoing valvular heart surgery. Preoperative nutritional status was evaluated by the prognostic nutritional index (PNI), Geriatric Nutritional Risk Index (GNRI), and controlling nutritional status (CONUT)… Read more about this study

About this study

The investigators investigated the clinical impacts of preoperative nutritional status on mortality in patients undergoing valvular heart surgery. Preoperative nutritional status was evaluated by the prognostic nutritional index (PNI), Geriatric Nutritional Risk Index (GNRI), and controlling nutritional status (CONUT) score. The primary outcome was the association between preoperative nutritional status evaluated by PNI, GNRI, and CONUT score and postoperative mortality. The predictive discrimination ability for mortality between PNI, GNRI, and CONUT were compared. Risk factors for mortality were identified.

What is being measured

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

  1. postoperative mortality according to peroperative nutritional status

    The association between preoperative nutritional status evaluated by the prognostic nutritional index (PNI), Geriatric Nutritional Risk Index (GNRI), and controlling nutritional status (CONUT) score and postoperative mortality is evaluated.

    Measured: 1 year after surgery

  2. postoperative mortality according to peroperative nutritional status

    The association between preoperative nutritional status evaluated by the prognostic nutritional index (PNI), Geriatric Nutritional Risk Index (GNRI), and controlling nutritional status (CONUT) score and postoperative mortality is evaluated.

    Measured: 2 year after surgery

Secondary outcomes (2)
  1. predictive discrimination ability for mortality between PNI, GNRI, and CONUT

    The predictive discrimination abilities for mortality between PNI, GNRI, and CONUT score are compared.

    Measured: 1 year after surgery

  2. predictive discrimination ability for mortality between PNI, GNRI, and CONUT

    The predictive discrimination abilities for mortality between PNI, GNRI, and CONUT score are compared.

    Measured: 2 year after surgery

What does the primary outcome measure?

postoperative mortality according to peroperative nutritional status (time frame: 1 year after surgery). The study lists 2 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 NCT04307732, which also lists 1 linked publication.

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.
