The HeartShield 360 panel goes further that a basic lipid profile by assessing apolipoproteins—ApoA‑I (the main HDL protein), ApoB (the key marker of atherogenic particle number), and their ratio, one of the strongest predictors of heart‑attack risk—along with ApoC‑II, ApoC‑III, and ApoE, which influence triglyceride metabolism and lipid transport. The panel also evaluates small dense LDL particles, which are more likely to penetrate artery walls, and Lipoprotein(a), a genetically determined, highly atherogenic particle. Finally, high‑sensitivity CRP measures underlying vascular inflammation, offering insight into plaque instability and overall cardiovascular risk.
