Boston Heart HDL Map

The amount of apoA-I protein in each of the five HDL subclasses, providing information to accurately identify patients at increased cardiovascular disease risk.

5 Biomarkers Included

HDL Alpha 1

Concentration of of apoA-I protein in very large, mature HDL particles rich in cholesterol, considered the most protective for cardiovascular health.

HDL Alpha 2

Concentration of of apoA-I protein in large HDL particles rich in cholesterol that are cardioprotective but slightly less so than HDL Alpha-1.

HDL Alpha 3

Concentration of of apoA-I protein in medium-sized HDL particle with intermediate roles in cholesterol transport and cardiovascular protection.

HDL Alpha 4

Concentration of of apoA-I protein in small HDL particles that have reduced cholesterol-carrying capacity and are less protective.

HDL Pre-Beta 1

Concentration of of apoA-I protein in pre-beta HDL particles that very small, nascent HDL particles that initiate reverse cholesterol transport; high levels may indicate impaired HDL maturation.
