The aim of the study is to evaluate a clinically and economically most effective diagnostic algorithm for prediction of inflammatory response related complications in patients undergoing heart surgery with use of cardiopulmonary bypass.

Condition Intervention Phase
Systemic Inflammatory Response Syndrome
Procedure: cardiac surgery with CPB use
Phase 4

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: INFLACOR - (INFLA-mmation, A-fter, C-ardiac, O-pe-R-ation) - Evaluation of Selected Genetic Polymorphisms, Inflammatory Mediators, and Physiologic Parameters in the Prognosis of Postoperative Complications in Patients Undergoing Cardiopulmonary Bypass Cardiac Surgery

Further study details as provided by Medical University of Gdansk:

Primary Outcome Measures:
  • Clinical phenotypes of inflammatory response: SIRS, acute lung injury/acute respiratory distress syndrome, acute kidney injury, atrial fibrillation, postoperative psychosis, perioperative myocardial infarct/injury, sepsis. [ Time Frame: between day 2 after operation and hospital discharge ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • all cause inhospital mortality [ Time Frame: from day 2 after operation ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA
plasma, serum, and blood morphologic elements after centrifugation frozen to -75C.

Enrollment: 525
Study Start Date: October 2009
Study Completion Date: November 2012
Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
CPB cardiac surgery
Adult patients, who signed the informed consent, intervention: first-time scheduled heart surgery with CPB use.
Procedure: cardiac surgery with CPB use
heart or ascending aorta surgery performed with use of cardiopulmonary bypass with or without aortic cross clamping.
Other Names:
  • heart valve surgery
  • open heart surgery

Detailed Description:

Identified so far predictors of mortality and/or morbidity in patients who undergo heart surgery with cardiopulmonary bypass (CPB), used in previous risk prediction models (EUROSCORE, CABDEAL, Cleveland), will be compared with new candidate variables:

  1. anamnestic: recent tooth extractions, chronic inflammatory diseases, specific drug use;
  2. biochemical: C-reacting protein, interleukin-6, tumor necrosing factor alpha;
  3. genetical: single nucleotide polymorphisms of 10 genes associated with inflammatory response; and
  4. clinical from the 1. postoperative day: systemic inflammatory response syndrome, APACHE-III score;

against their predictive capability of selected clinical phenotypes of inflammatory response occuring after surgery, beginning from day 2. after surgery.
