At Endless Health, we believe in empowering individuals with actionable insights to optimize their heart and metabolic health. Our full loop health support strategy is grounded in the latest scientific research, focusing on Apolipoprotein B (ApoB) and Hemoglobin A1C (A1C) as the key biomarkers for heart and metabolic health (cardiometabolic health) coaching. These biomarkers have been shown to be the most predictive of long-term health risk and are highly responsive to lifestyle and behavioral changes. By monitoring ApoB and A1C levels, we provide personalized, data-driven guidance to help our users make informed decisions about their diet, exercise, and other lifestyle factors, ultimately reducing their risk of cardiovascular disease and improving overall health.

Importantly, the protein ApoB and A1C can be measured through a simple blood test gives us crucial information about the amount of these plaque-causing substances in your blood, making it a key biomarker for monitoring the risk and development of heart disease. The problem is most people, including many generalist doctors, do not know about this research-backed test preventive cardiologists and lipid experts around the world are recommending or how it measures the underlying basis for heart disease.

What is heart disease?

Heart disease is the most significant cause of death and premature death worldwide, in rich countries and poor countries alike. While heart disease can be stopped by implementing lifestyle changes that reduce the buildup of plaques, most people do not know when they are at risk and lack the motivation to implement needed changes.

Heart disease is the build-up of fatty substances, cholesterol, cellular waste products, calcium and other substances in the inner lining of arteries and veins, the life-supporting highways for oxygen-carrying blood cells. This build-up, known as plaques, can grow large enough to significantly reduce the blood's flow through an artery or break off and cause clots or blockages, leading to conditions such as heart failure, heart attack, embolisms, or stroke. This collection of conditions, resulting from plaque build-up, are known as atherogenic cardiovascular diseases, which we call heart disease broadly. The first sign of the progression of heart disease is increased levels of small apolipoproteins, which form the basis for plaques. And the most accurate test for these small apolipoproteins is the ApoB blood test.

Progress in Heart

When it comes to assessing heart health, many people rely on traditional biomarkers such as low density lipoproteins - LDL,-P often arbitrarily referred to as "bad cholesterol" to assess their heart health. For example, if an individual's LDL-P levels fall within the "satisfactory range," they tend to perceive themselves as having good heart health, and conversely, if their LDL-P levels are outside this range, they consider their heart health to be compromised. LDL-P is a popular tool because it was proven to be a much better predictor of long-term cardiovascular risk than blood pressure because it measures the underlying cause of heart disease, lipoproteins that build up on However, it is important to note that measuring LDL-P is just one component of assessing your heart health. Numerous studies have demonstrated that relying solely on LDL-P levels does not provide a complete evaluation of your present and future heart health.

ApoB: The Key Heart Health Predictor

Research suggests that the biomarker Apolipoprotein B (ApoB) is considered the most powerful indicator available for assessing the risk of heart disease, surpassing traditional biomarkers like LDL-P. ApoB is the primary protein component of all plaque forming particles, which are responsible for the development of heart disease—not only LDL-P.
Leading health organizations like the American Heart Association (AHA) and the European Society of Cardiology (ESC) recognize the importance of ApoB and recommend its use over traditional LDL-P testing in their latest guidelines for cardiologists. Despite being a leading measurement and predictor of cardiovascular health, ApoB is not routinely tested as a standard practice during regular annual checkups due to slow adoption by general practice physicians.

Understanding Total Cholesterol and Apolipoproteins

Understanding the role of ApoB and apolipoproteins is crucial in demystifying the term 'total cholesterol.' Cholesterol, a waxy substance found in the bloodstream, is often misunderstood. It's essential for cell membrane production, hormone synthesis, and vitamin D production. However, cholesterol alone doesn't cause heart disease; rather, it's the lipoproteins (like ApoB) that transport cholesterol in the blood that contribute to plaque buildup and cardiovascular risk.

The significance of ApoB as a predictor compared to other biomarkers

Apolipoproteins, such as ApoB, are the protein components of all plaque forming lipoproteins. According to leading cardiovascular doctors and scientists, ApoB is a better predictor of heart disease risk than traditional cholesterol markers, as it accounts for all plaque forming atherogenic particles in the blood, including LDL-P and, VLDL, IDL, and Lip(A).

Since every plaque forming particle contains a ApoB molecule (1:1 ratio), we can further access the size and composition of these particles and this is key in assessing cardiovascular risk.

For example, studies have shown that more, smaller LDL particles are considered more dangerous compared to fewer, larger LDL-P particles as they can more easily generate plaque and accumulate your arteries. Both having more, smaller or less, larger particles would give the same LDL-P result, but more particles means a higher ApoB level. By testing your ApoB, it is possible to identify the presence of these smaller, denser, and more dangerous particles in your arteries, giving a more accurate result according to consensus among lipid experts.

The assessment of cardiovascular disease (CVD) can be limited by relying solely on total cholesterol levels, as it is possible to have a high number of small LDL-P particles while still testing within the normal cholesterol range. This presents a barrier and flaw in the current evaluation process for CVD. ApoB testing plays a crucial role in identifying this important distinction. Unlike an LDL-P test, an ApoB test can reveal whether the total cholesterol in your body is distributed among only 100 particles or 1000 particles. This information provides a more precise understanding of your cardiovascular health and can help in assessing the risk of CVD more accurately.

The AHA's guidelines state that ApoB is a stronger indicator of atherogenicity than LDL-C alone. Similarly, the ESC's guidelines focus on ApoB as the primary predictor for long-term heart health risk.

A1C – The Key Metabolic Health Predictor

Hemoglobin A1C (HbA1c) has emerged as the most significant and powerful predictor for long-term metabolic health, surpassing traditional biomarkers like fasting blood glucose. A1C is a reflection of your average blood sugar levels over the past 2-3 months and plays a crucial role in the early identification and management of prediabetes and diabetes.
‍
A1C is a measure of glycated hemoglobin, which is formed when glucose in the blood binds to the hemoglobin in red blood cells. Elevated A1C levels indicate a higher average blood sugar level, which can increase the risk of developing diabetes and its complications. The medical community widely recognizes the importance of A1C testing as the gold standard for assessing long-term blood sugar control.

A1C as a predictor compared to other biomarkers

Understanding the role of A1C is vital in managing blood sugar levels and preventing the onset of diabetes. Consensus in the medical community supports A1C as the best predictor for long-term metabolic health due to its ability to provide a more comprehensive view of blood sugar control over time, as opposed to a single fasting blood glucose measurement.

By regularly monitoring your A1C levels and adopting a healthy lifestyle, you can take control of your metabolic health and prevent the onset of diabetes.

When we take a path of unhealthy choices, such as dealing with too much stress, skimping on sleep, living a sedentary life, avoiding social interaction, and eating poorly, we often find ourselves in the shadow of hyperlipidemia. This condition, marked by high levels of a substance called apolipoprotein B (apoB), can be a harbinger of serious health problems like strokes, blood clots, heart failure, and various heart diseases.

However, if we choose a healthier path, one where we strive for a peaceful mindset, ensure adequate sleep, engage in regular exercise, foster social connections, and eat a well-balanced diet, we can create a different outcome. This road leads us towards lower levels of harmful lipids that cause atherosclerosis. This can be like a domino effect, leading to an array of benefits such as longer life, enhanced creativity, better resilience against stress, sharper mental function, and even an increase in physical attractiveness.

In summary, the choices we make every day, whether good or bad, directly influence our health.
