Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Titles & IDs
Public title
A study to determine the ability of a blood test for B-type Natriuretic Peptide signal peptide (BNP-SP) to act as an early indicator in Acute Coronary Syndrome (ACS)).
Scientific title
A study to determine the diagnostic test performance (sensitivity, specificity, negative predictive value, positive predictive value, accuracy and prognostic value) of B-type Natriuretic Peptide Single Peptide (BNP-SP) measurement in detection of Acute Coronary Syndrome (ACS) (including those with ischemia short of infarction) within a population of “all-comers” with chest discomfort

Description of intervention(s) / exposure
We will measure serial B-type Natriuretic Peptide signal peptide (BNP-SP)concentrations in 2000 patients presenting to the Emergency Department within 24 hours of symptom onset of possible Acute Coronary Syndrome (ACS).

Clinical history and physical examination will be undertaken. Venous blood samples for cardiac biomarkers will be obtained at 1, 2, 3, hours post admission and again at 6-12, 24 & 48 hours if still in hospital or attend an outpatient clinic.
Patients will be followed up for 30 day and 6 month events for the composite end-point of: All cause mortality and/or new ACS and/or readmission to hospital with arrhythmia or heart failure.

Outcomes
Primary outcome [1] 4926 0
The primary outcome of this proposal will be the identification of B-type Natriuretic Peptide signal peptide (BNP-SP) as a novel, specific biomarker of acute cardiac injury. For each blood sample, we will measure plasma BNP-SP as well as the standard serial biomarker concentrations of troponin, creatine kinase and myoglobin.
Timepoint [1] 4926 0
Additional assessment time points at 3, 6-12 & 48 hours and 30 days and 6 months post admission
Secondary outcome [1] 8309 0
The secondary outcome will be the potential identification of a new class of circulating biomarkers that may have diagnostic potential in pathophysiology. For each blood sample, we will measure plasma BNP-SP as well as the standard serial biomarker concentrations of troponin, creatine kinase and myoglobin
Timepoint [1] 8309 0
Additional assessment time points at 3, 6-12 & 48 hours and 30 days and 6 months post admission
