Did you know?

50% of Heart Attack victims have normal cholesterol.1

That’s because multiple factors in addition to cholesterol are required to determine the underlying cause of Heart Attack.2

Beyond Cholesterol testing.
Beyond Plaque testing.

Finally, a blood test for the
leading cause of Heart Attacks:

Unstable Cardiac Lesion Rupture.

The PULS (Protein Unstable Lesion Signature) Test measures the most clinically-significant protein biomarkers that measure the body's immune system response to arterial injury.3

These injuries lead to the formation and progression of cardiac lesions which may become unstable and rupture, leading to cardiac event.

What are Unstable Cardiac Lesions and how do they form?

Unstable Cardiac Lesions form within the artery wall over time, often without any signs or symptoms, through a process of continuous arterial injury and repair.4,5

Artery wall with Unstable Cardiac Lesion in danger of rupturing

  • 1. Arterial Injury

  • 2. Cell Proliferation

  • 3. Stimulation of new blood Cells

  • 4. Cell Adhesion & Platelet Aggregation

  • 5. Cell Death

An unstable lesion begins to form when oxidized or damaged lipids bind and aggregate on the arterial surface, causing an injury.

PULS test results can help prevent a heart attack - starting now.

The PULS Test can provide your physician with valuable information that can be used to determine the most appropriate course of action according to clinical guidelines.
