About this study

Acute aortic dissection (AAD) is an acute vascular lesions with high early misdiagnosis rate(31.8%), and mortality rate was 38%. In recent years, the incidence is rising and serious threat to human health. At present, the clinical diagnosis of AAD commonly used imaging methods, including chest X-ray, B ultrasound, CT, MRI and aortic angiography. Chest X-ray and two-dimensional ultrasound is limited in diagnosis of AAD, esophageal ultrasonography can display the intimal, identify the true and false lumen, but greater risk. CT, MRI and aortic angiography can be used as diagnosis method, but time-consuming, expensive and requires handling patients in emergency situations, should not be used as the preferred. Therefore, it is significance that biomarkers with high specificity and sensitivity for clinical fast diagnosis of AAD.

Parts small sample tests found that single serum α-smooth muscle actin (α-SMA), myosin heavy chain(MHC) and human soluble elastin fragments (sELAF) levels in patients with AAD were significantly higher than that of others (normal people, acute myocardial infarction patients). But because of the small study sample, limited control risk factors and incomplete comparison, their conclusions were questionable. In our previous studies also found that serum α-SMA, MHC and sELAF levels and the pathogenesis of AAD and prognosis are closely related. Therefore, on the basis, a prospective study is needed. We observe all the three biomarkers in enrolled patients with acute chest pain in emergency department, levels in healthy volunteers as the blank control. Then make definite diagnosis of the enrolled patients, and further observe the biomarkers dynamic change in AAD. Lastly, evaluate the early diagnostic value of combination serum α-SMA, MHC and sELAF level on patients with AAD.

Read the detailed description

This is a prospective clinical study designed to procure blood samples from patients who present to the Emergency Department with suspected AAD.

Subjects enrolled in this study will sign and informed consent and have 3 blood samples drawn at different time points during their emergency department visit. In addition, data will be collected about the patient's health history, hospital procedures, and final diagnosis.

Blood samples collected in this study will be sent to laboratory for long-term storage and analysis in the future for these blood markers as they become available. No genetic testing will be conducted on these samples.

Questions about this trial

What is this clinical trial studying?

An observational study of Aortic Dissection and Biomarkers and Early Diagnosis, run by Central South University 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 5 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 27 May 2013. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact CHAI Xiangping, MD (+86-13787204259, fenghuaxuepiao@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Diagnostic accuracy(sensitivity and specificity of 400 participates for diagnosing acute aortic dissection) of serum biomarkers on patients with AAD. (time frame: 1 day (Emergency room without follow-up)). 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 27 May 2013.
