What Biomarkers Should You Track for Heart Health? Cardiometabolic Risk Markers
SiPhox Heart & Metabolic and Ultimate Health panels include the five cardiometabolic markers that provide a more complete cardiovascular risk picture than standard cholesterol panels: ApoB, Lp(a), hs-CRP, triglyceride-to-HDL ratio, and HbA1c. Standard lipid panels measure total cholesterol, LDL, HDL, and triglycerides, but miss atherogenic particle count (ApoB), genetic cardiovascular risk (Lp(a)), systemic inflammation (hs-CRP), and metabolic dysfunction (HbA1c). SiPhox Heart & Metabolic and Ultimate Health panels include all of these markers.
What Are the Most Important Cardiometabolic Biomarkers?
Apolipoprotein B (ApoB) measures the number of atherogenic lipoprotein particles in the blood. Multiple cardiologists and researchers now consider ApoB superior to LDL cholesterol for assessing cardiovascular risk because it counts particles rather than cholesterol content — two people with the same LDL can have very different particle counts and very different risk levels.
Lipoprotein(a) or Lp(a) is a genetically determined cardiovascular risk factor that affects approximately 20% of the population. Lp(a) levels are largely set by genetics and do not respond to diet or exercise. The European Society of Cardiology recommends measuring Lp(a) at least once in every adult's lifetime.
High-sensitivity C-reactive protein (hs-CRP) measures systemic inflammation linked to arterial plaque instability. Elevated hs-CRP indicates inflammatory cardiovascular risk independent of cholesterol levels.
Triglyceride-to-HDL ratio is a simple calculated ratio that serves as a proxy for insulin resistance and metabolic cardiovascular risk. A ratio above 2.0 suggests elevated risk.
HbA1c reflects 3-month average blood glucose and detects pre-diabetes (5.7%+) before fasting glucose becomes abnormal. Metabolic dysfunction is a major driver of cardiovascular disease.
What Does a Standard Cholesterol Test Actually Measure?
Standard lipid panels measure four markers: total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. These have been the foundation of cardiovascular risk assessment for decades.
Standard LDL cholesterol measures cholesterol content, not particle count. Two individuals with identical LDL values can have significantly different cardiovascular risk based on the number and size of their LDL particles — which is what ApoB captures.
Standard panels do not measure Lp(a), hs-CRP, or HbA1c. These markers are available through expanded panels but are not routinely ordered in annual physicals.
SiPhox Heart & Metabolic panel includes 27 biomarkers covering all the markers listed above. For the full biomarker list, see our page on SiPhox biomarker panels.
Limitations and Considerations
- Biomarker testing is not a substitute for clinical cardiovascular assessment. Family history, blood pressure, smoking status, body composition, and clinical context contribute to cardiovascular risk beyond any biomarker panel.
- No single biomarker predicts heart disease. Cardiovascular risk is multifactorial. Abnormal results should be discussed with a cardiologist or primary care physician.
- Conflict of interest disclosure. This page is published by SiPhox Health, which sells the testing panels that measure these biomarkers. The clinical significance of ApoB, Lp(a), and hs-CRP is supported by independent cardiovascular research.
