VIDAS^® High sensitive Troponin I

Did you know? Every year, 16 million people worldwide die of cardiovascular diseases, specifically heart attacks or stroke (1). Chest pain is among the top 10 reasons to visit an emergency department (ED), accounting for about 5% of all ED visits (2). Expected prevalence of acute myocardial infarction (MI) in chest pain patients in the ED is between 5 and 10% for ST-segment elevation MI (STEMI) and 15 and 20% for non-ST segment elevation MI (NSTEMI)(3).

Our VIDAS® High sensitive Troponin I assay helps deliver accurate diagnosis of MI in only 2 hours for improved patient outcomes and optimized patient management in the ED.

Benefits of high sensitivity troponins

The new generation of highly sensitive troponin assays allows earlier detection of acute MI, with a shortening of the time window for serial measurement to 3 hours.

Cardiac troponin (cTn) has become a continuous variable with accurate measurement below the 99th percentile as well as small absolute changes within 1 or 2 hours. This has enabled development of algorithms for reliable rule-out and rule-in of acute MI within 2 hours(4).

As a result, high-sensitivity cTn assays are an important aid to clinicians to optimize the management of ACS:

• Diagnosis
  
  • Mandatory tool, in addition to clinical assessment and an electrocardiogram (ECG), to make a definitive diagnosis of acute MI.
  •  Serial measurement to differentiate acute from chronic cardiac myocyte damage.

• Risk stratification
  
  • Additional tool in risk stratification to guide therapeutic decision making.

Deliver high performance

Our VIDAS® High sensitive Troponin I test is an aid in the diagnosis of myocardial infarction. It is also an aid in the risk stratification of patients with symptoms suggestive of ACS with respect to relative risk of all-cause mortality and major adverse cardiac events (MACE) consisting of MI and revascularization, at 30 days.

The 99th percentile of a presumably healthy population, the recommended cut-off for the diagnosis of MI, has been defined at 19 ng/L.

The CV at the 99th percentile is equal to 7%.

Accelerate patient triage

The use of a validated 2-hour algorithm guarantees high diagnostic accuracy:

* Data from validation study in 592 patients
** Difference in cTn concentration
*** Negative Predictive Value
**** Positive Predictive Value

• Algorithm based on admission values and absolute changes within the first 2 hours.
• Delivers a diagnosis - safe rule-out and accurate rule-in - of acute MI (NSTEMI) in the vast majority (70%) of suspected chest pain patients.
• Shortens the time needed to triage chest pain patients in the ED (will obviate the need for prolonged monitoring with frequent serial blood sampling).

A complete and user-friendly solution for Emergency Care

The VIDAS® High sensitive Troponin I assay is run on the VIDAS® family of instruments. Easy-to-use and reliable, they offer rapid results and are well adapted to emergency situations.

Available on the same platform:

• VIDAS® NT-proBNP2
• VIDAS® D-Dimer Exclusion IITM
• VIDAS® B.R.A.H.M.S PCT™
