Puls Cardiac Test

---

We’ve been working on bringing the PULS test to the UK market for a long time now. This is undoubtedly one of the biggest advancements in cardio-metabolic testing and we’re proud and excited to provide you with it. – Humphrey Bacchus

The PULS (Protein Unstable Lesion Signature) Cardiac Test measures key clinical risk factors, including those commonly measured in the Framingham risk calculator, as well as 9 unique protein biomarkers.

These markers are associated with the biological pathways underlying cardiac lesion formation, progression and rupture.

50% of people who have a heart attack have ‘normal’ cholesterol and many adults are considered at ‘intermediate risk’.

The refined methodology of PULS cardiac risk assessment provides an improved calculation of a patient’s near-term (5 year) risk for a heart attack, and allows for the reclassification of nearly half of those patients considered in the clinical ‘grey zone’.

An Elevated PULS Cardiac Test May Identify:

• Coronary heart disease development
• Presence of unstable/vulnerable arterial plaque
• Increased near-term risk of a heart attack

Atherosclerotic disease progression is characterised by chronic endothelial damage and an accumulation of fatty plaque within the arterial wall. Unstable plaque can rupture and lead to arterial blockage causing a heart attack. The first steps in prevention are the identification of individuals at near-term risk of a heart attack, and allowing for more aggressive therapy to potentially avoid a future event.

Clinical Use:

The PULS Cardiac Test may be performed on individuals at intermediate risk with one or more risk factors for coronary heart disease.

Clinical Significance:

• Cardiovascular risk prediction models such as the
  Framingham Risk Score calculate risk of a cardiovascular
  event within the next 10 years. When used, these calculations
  rely heavily on established clinical risk factors (1) which may not
  fully estimate the prevalence of cardiovascular disease in the
  general population (2, 3)

• The PULS Cardiac Test measures clinically significant
  proteins in the blood associated with active unstable lesion
  formation and when combined with established clinical risk
  factors, predicts whether a cardiac lesion could rupture
  within a 5 year period (4).

• In the Multi-Ethnic Study of Atherosclerosis (MESA), the PULS Cardiac Test outperformed a common risk calculator, yielding a net reclassification index of 42.7% in individuals defined as intermediate risk by the Framingham Risk Score (4). Reclassification of those initially defined as intermediate risk to high risk may result in more appropriate therapeutic intervention.

• In a large clinical trial, the PULS Cardiac Test identified 61% of
  patients who went on to have a cardiac event who otherwise
  would have been missed using established risk factors alone (5).

Testing Frequency:

The frequency of ordering The PULS Test is determined by an
individual’s medical history, but may be monitored more frequently
in those at moderate to high risk for cardiovascular disease.

Sample Type:

The PULS Cardiac Test should be performed on a serum and EDTA whole blood sample. Patients do not need to fast for the test.
