Heart disease remains a leading cause of death globally, often developing silently over years through lifestyle factors and internal processes that go unnoticed. While many associate heart problems with chest pain or shortness of breath, significant damage can occur long before these symptoms manifest. Increasingly, medical professionals are focusing on identifying subtle biomarkers – measurable indicators within the body – that can reveal elevated risk for heart attack and other cardiovascular events, allowing for proactive intervention.
Dr. Vassily Eliopoulos, a longevity expert with an MD from Cornell University and Co-Founder and Chief Medical Officer of Longevity Health, recently highlighted five key biomarkers that individuals over 40 should be aware of. These aren’t routinely checked in standard physicals, yet they offer a crucial window into potential heart health issues. “Heart disease is a silent process,” Dr. Eliopoulos explained in a recent social media video. “No warning, no pain, no sign until something breaks, and by the time you feel it, it’s been building for decades.” Identifying these risks early can be transformative, shifting the focus from reactive treatment to preventative care.
ApoB: Beyond Traditional Cholesterol Measures
While standard cholesterol panels often focus on LDL (“bad” cholesterol), Dr. Eliopoulos emphasizes the importance of measuring Apolipoprotein B (ApoB). ApoB is the primary protein responsible for carrying atherogenic particles – those that contribute to plaque buildup – in the bloodstream. According to the National Institutes of Health, ApoB provides a more accurate assessment of cardiovascular risk than LDL alone as it counts all potentially harmful particles, not just those classified as LDL.

Insulin Resistance: A Hidden Metabolic Driver
Insulin resistance, a condition where cells don’t respond effectively to insulin, is a key underlying factor in many chronic diseases, including heart disease. Often, blood sugar levels appear normal even when insulin resistance is present. Dr. Eliopoulos advocates for a fasting insulin test as a more sensitive indicator. While not routinely recommended, a fasting insulin level can reveal how hard the pancreas is working to maintain normal blood sugar. Elevated levels suggest the body is becoming less sensitive to insulin, potentially leading to a cascade of metabolic problems. The American Diabetes Association notes that insulin resistance is often present years before the development of type 2 diabetes, a significant risk factor for heart disease.

Soft Plaque: The Silent Threat
Not all plaque is created equal. Traditional stress tests primarily detect hardened, flow-limiting blockages in arteries. However, “soft plaque” – unstable, lipid-rich deposits – often goes unnoticed. Dr. Eliopoulos explains that soft plaque doesn’t necessarily restrict blood flow significantly, so it may not show up on a standard stress test. However, it’s far more prone to rupture, leading to sudden cardiac events like heart attacks. Advanced imaging techniques, such as coronary computed tomography angiography (CCTA), can help identify soft plaque, but are not typically part of routine screening. The American Heart Association emphasizes the importance of understanding plaque vulnerability in assessing cardiovascular risk.

Chronic Inflammation: The Underlying Fire
Chronic, low-grade inflammation is increasingly recognized as a key driver of many chronic diseases, including atherosclerosis (hardening of the arteries). Dr. Eliopoulos points to markers like high-sensitivity C-reactive protein (hs-CRP), homocysteine, and oxidized LDL as indicators of underlying arterial damage. These markers can detect inflammation long before any noticeable symptoms appear. Elevated hs-CRP, for example, signals systemic inflammation, while elevated homocysteine has been linked to increased risk of blood clots and arterial damage. The Mayo Clinic provides detailed information on C-reactive protein and its role in inflammation. Learn more about C-reactive protein from the Mayo Clinic.
Lp(a): A Genetically Determined Risk
Lipoprotein(a), or Lp(a), is a genetically determined particle similar to LDL, but with a unique structure that significantly increases the risk of cardiovascular disease. Dr. Eliopoulos highlights that nearly one in five people carry elevated levels of Lp(a), making it a strong predictor of heart disease risk. However, it’s often overlooked in routine screenings. Unlike LDL cholesterol, Lp(a) doesn’t respond well to dietary changes or statin medications, making early identification even more crucial. The European Society of Cardiology has recently emphasized the importance of Lp(a) measurement in risk assessment. Read about Lp(a) cholesterol from the European Society of Cardiology.
Dr. Eliopoulos stresses that while these processes unfold silently, they are measurable. Tracking these biomarkers can provide a more comprehensive understanding of individual cardiovascular risk and allow for timely preventative measures. He advocates for a more proactive approach to heart health, moving beyond traditional cholesterol checks to a broader assessment of these often-overlooked indicators.
