About this study

Official title: Predictive Value of the Contrast Media Volume to Creatinine Clearance Ratio for the Risk of Contrast-Induced Nephropathy After Coronary Angiography

To determine a relatively safe contrast media volume to creatinine clearance cut-off value to avoid contrast-induced nephropathy in patients following coronary angiography

Read the detailed description

Contrast media volume to creatinine clearance (V/CrCl) ratios were obtained from consecutive consenting patients after coronary angiography. Receiver-operator characteristic (ROC) curves were used to identify the optimal sensitivity for the observed range of V/CrCl. The predictive value of V/CrCl for the risk of contrast-induced nephropathy was assessed using multivariate logistic regression.Subgroup analysis was performed on patients with creatinine clearance < 60 ml/min,diabetes,emergent angiography.

What is being measured

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

  1. Contrast-Induced Nephropathy

    Contrast-Induced Nephropathy was defined as an increase in serum creatinine of more than 0.5 mg/dl from the baseline within 48-72 h of contrast exposure

    Measured: 48-72 h

Secondary outcomes (4)
  1. An early abnormal increase in serum creatinine

    An early abnormal increase in serum creatinine defined as an increase in serum creatinine of more than 0.5 mg/dl from the baseline within 24h of contrast exposure

    Measured: 24h

  2. Major adverse clinical events

    Major adverse clinical events: death, requiring renal replacement therapy, 2nd myocardial infarction,target revascularization,acute heart failure, mechanical ventilation,2nd angina,tachyarrhythmia,hypotension,intra-aortic balloon pump and stroke

    Measured: 1 year

  3. Major adverse clinical events

    Major adverse clinical events: death, requiring renal replacement therapy, 2nd myocardial infarction,target revascularization,acute heart failure, mechanical ventilation,2nd angina,tachyarrhythmia,hypotension,intra-aortic balloon pump and stroke

    Measured: 1month

  4. An early abnormal increase in serum cystatin C

    An early abnormal increase in serum cystatin C was defined as an increase more than 10% from the baseline within 24h of contrast exposure

    Measured: 24h

Questions about this trial

What is this clinical trial studying?

An observational study of Contrast Induced Nephropathy, run by Guangdong Provincial People's Hospital at 1 site in China.

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 2 inclusion and 7 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 16 Sep 2014. 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 China. 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?

Contrast-Induced Nephropathy (time frame: 48-72 h). 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 NCT01400295, which also lists 4 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 16 Sep 2014.
