Most of us treat heart health like a smoke alarm. We only react when the alarm goes off. We rely on standard blood tests to tell us if we are "healthy," but there is a silent gap between a "normal" lab result and optimal cellular function.
Science is shifting from reactive diagnostics to proactive epigenetics. While blood tests measure what has already changed in your system, epigenetics measures the "software" running your cardiovascular health.
It's the difference between checking the oil after the engine light comes on and monitoring your biology in a way that prevents the friction in the first place.
Beyond the Blood Test
Standard blood work is a vital tool, but it is not the only biomarker you can use for tracking and measuring your health, and it is often a lagging indicator.
If your cholesterol or blood pressure markers, for instance, are looking "fine" according to standard ranges, but you have early-stage arterial stiffening or cellular stress, it may not show up in your routine blood work for years.
Blood analysis is, in many ways, a delayed metric. By the time your results point to a potential issue, the structural changes to your heart may already be well underway.
An example would be checking your Troponin levels or NT-proBNP (a protein released when the heart is under strain). These are excellent markers for identifying when a heart is already under acute stress or has suffered damage. You are provided with a reference range to ascertain whether an issue exists, but these often only spike once the "fire" has already started.
Here is the problem: the cardiovascular system is incredibly resilient. Your heart can compensate for minor cellular wear or early-stage structural remodelling, the gradual changes to the heart's size, shape and function, for a long time before cardiac proteins such as troponin begin to appear in your bloodstream at detectable levels. This means that the precursors to heart disease can remain "silent" on a standard blood test until a clinical event occurs.
Epigenetics — The True Frontier of Preventative Heart Health
This is why epigenetics, and specifically DNA methylation, represents the true frontier of preventative heart health. It allows you to see the "smoke", the cellular stress and changes in genetic expression, before the "fire" shows up in your clinical blood results.
DNA methylation is one of the key mechanisms within epigenetics: chemical tags that attach to your DNA and influence how your genes are switched on or off. Unlike your genetic code, which remains fixed throughout your life, these methylation patterns shift in response to how you live, your diet, sleep, stress levels, exercise and the supplements you take. Measuring these patterns gives us a window into how your body is truly ageing at a cellular level.
Muhdo Heart Age
Muhdo Heart Age is a next-generation, saliva-based epigenetic clock that estimates your biological "heart age." By analysing DNA methylation patterns across 25 key CpG sites, it provides a more personalised measure of cardiovascular ageing than chronological age alone, particularly in relation to heart health risk.
Unlike chronological age, this approach captures underlying biological changes linked to disease risk, offering a powerful indicator of future heart health.
Please take the time to read our latest proof-of-concept study, in which we demonstrate that expanding a saliva-based epigenetic clock with a panel of CpGs tied to cardiovascular health yields a more powerful tool for identifying risk in a heart-disease population: https://tinyurl.com/375dweut
