Trial summary

Cardiac troponin is the preferred biomarker for the diagnosis of acute myocardial infarction. Whereas the diagnosis is based on an increase and/or decrease in the concentrations of cardiac troponins with at least one value above the 99th percentile value of the reference population together with the evidence of… Read more about this study

About this study

Cardiac troponin is the preferred biomarker for the diagnosis of acute myocardial infarction. Whereas the diagnosis is based on an increase and/or decrease in the concentrations of cardiac troponins with at least one value above the 99th percentile value of the reference population together with the evidence of ischemia, serial sampling is needed. Knowledge of the variation in cardiac troponin levels over time in individuals in a normal rest state (not during an acute myocardial infarction), also called the biological variation, is important regarding the interpretation of the serial cardiac troponin levels. A recent study by our group showed a circadian rhythm in cardiac troponin levels. This circadian rhythm is important regarding the interpretation of the serial cardiac troponin levels.

Increased cTnI and cTnT concentrations are common in subjects with renal impairment. The mechanism of the elevated concentration of cTn in these subjects is still unclear. It is hypothesized that impaired renal clearance contributes to elevated levels of cTn. However, it is not clear whether renal function affects the biological variation and circadian rhythm of cTn. The monitoring of the biological variation and circadian rhythm of cTn in subjects with impaired renal function creates the opportunity to assess the effect of renal clearance on the circadian rhythm of cardiac troponins.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Kidney Diseases, run by Maastricht University Medical Center at 1 site in Netherlands.

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 3 inclusion and 3 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 18 Feb 2016. 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 Netherlands. 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?

Cardiac Troponins (cardiac troponin I (cTnI) and cardiac troponin T (cTnT)) (time frame: up to three months). 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 NCT02210897, which also lists 2 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 18 Feb 2016.
