Metabolic damage before symptoms: What AGEs reveal about cardiovascular risk. Some patients appear healthy on paper: normal HbA1c, controlled blood pressure, no symptoms, yet still develop cardiovascular disease over time. What early signal are we missing?
AGEs (Advanced Glycation End-products) are the end result of a reaction between sugars and proteins. These harmful compounds gradually accumulate under prolonged metabolic stress, such as oxidative stress, chronic hyperglycemia, or low-grade inflammation. AGEs damage tissues, increase arterial stiffness, and accelerate vascular aging.
Clinicians often describe cases like this:
A 58-year-old man with well-regulated type 2 diabetes (HbA1c 6.2%) but a remarkably high AGE score. In practice, this often prompts closer cardiovascular monitoring and lifestyle intervention, despite reassuring standard markers.
AGEs do not replace existing parameters such as LDL or CRP, but they may offer an additional layer of insight into early vascular burden, especially in patients who fall within the “grey zone,” where traditional risk scores offer limited clarity.
Although more than 350 scientific publications have used the AGE Reader to measure AGEs, we continue to collaborate with clinical teams to further explore the value of AGE measurement. At this stage, it is primarily an invitation – not only for researchers but also for clinicians – to view risk differently, act earlier, and take metabolic stress seriously before it manifests as symptoms.
