Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 99 years
  • All sexes
  • Adult, Older adult

Study population: Patients scheduled for cardiac surgery were assessed for the inclusion/exclusion criteria, provided signed informed consent, and were allocated to one of two treatments: IABP insertion before skin incision (IABP group) or no IABP insertion (control group). In all cases, the decision of the IABP insertion was generated in a previous Heart Team session, this team was integrated by a Clinical Cardiologist, Cardiac Interventionist, Cardiothoracic Surgeon and Anesthesiologist, in base on the personal risk/benefit of each patient. There was no blinding for patients or physicians in aware of the Heart Team decisions. Outcome assessors were unaware of the assigned treatment.

Who may be able to join

  • All patients greater than 18 years
  • Scheduled for coronary artery bypass graft (CABG) surgery were eligible
  • Multiple vessel disease with or without left main coronary artery (LMCA) significant stenosis (>50%)

About this study

Official title: Evaluation of Prophylactic Use of a Preoperative Intra-Aortic Ballon Pump in High-Risk Coronary Artery Bypass Graft Surgery: A Single-Centre Study

Background: The intra-aortic balloon balloon pump (IABP) has been used as a method of percutaneous circulatory assistance high surgical risk patients undergoing coronary artery bypass graft surgery (CABG); Although its applicability has been questioned by clinical trials showing poor impact to reduce the mortality due to cardiogenic shock associated with postoperative acute myocardial infarction (AMI), the real benefit reducing mortality in the postoperative context (PO) has not been determined examined through a prospective study with an adequate design.

Objective: To compare PO complications such as mortality, perioperative infarction and other complications in patients with high surgical risk undergoing CABG in comparison with controls.

Read the detailed description

Methods: Quasi-experimental, prospective, comparative, non-randomized study. The decision to place the BIAC is not part of the study and depends on the multidisciplinary decision of a Heart Team, based on the individualized risk / benefit. The study population consists on high surgical risk patients with atherosclerotic coronary disease undergoing CABG in our centre between 2014-2018. Patients are excluded if any condition is present: cardiogenic shock, with AMI 48 hours prior and / or severe aortic insufficiency. In one group BIAC will be inserted 1-6 hours before surgery (BIAC group) and a second group is control (non-BIAC group). A minimum 30-day postoperative follow-up of will be performed, with primary end points (mortality and AMI type V) and secondary end points (additional PO complications).

Analysis: An evaluation of normality distribution K-S will be performed, the means of quantitative (t-Test) and categorical variables (Fisher or χ² Pearson) will be compared. A multivariate analysis will be performed with linear logistic regression to evaluate the influence of age, sex, peripheral arterial disease (PAD) and EuroSCORE-II on the primary goal. Statistical significance will be considered when p <0.05. Softwares: GraphPad-Prism-5.0 and SPSS-15.0

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Intra-Aortic Ballon Pump insertionDevice

    The IABP (Ultraflex IAB 7.5F, 2.5mm; Arrow International, Reading, PA) was inserted percutaneously through the right femoral artery in the previous 1 - 6 hours before the scheduled surgery. Positioning of the IABP was guided by radioscopy. The balloon size was based on the patient's height (30, 40 or 50 cc). Transesophageal echocardiography was used to confirm correct IABP placement before and after CABG

Questions about this trial

What is this clinical trial studying?

An observational study of Ischemic Cardiomyopathy and Heart Failure, run by CMN "20 de Noviembre".

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 12 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 6 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

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?

30-Day All-Cause Mortality (time frame: 30 days). 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?
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 6 Mar 2019.
