Myths vs facts: Cardio Risk Check and Blutzucker

Combining a Cardio Risk Check with blood sugar (Blutzucker) testing is reasonable, but not all tests deliver what they promise. Fasting glucose and HbA1c are well-validated biomarkers for diabetes and cardiovascular risk – the evidence here is strong (human-strong). In contrast, many commercial DNA tests for 'cardio risk' rely on single gene variants with small effect sizes (e.g., 9p21, TCF7L2). They cannot predict risk precisely and are no substitute for classic risk factors like blood pressure, cholesterol, smoking, or exercise. A myth is that a 'genetic risk' is fate – in reality, lifestyle can often offset it. Another myth: normal blood sugar rules out high heart risk. Fact: many people with normal glucose still have elevated cardiovascular risk due to high triglycerides or LDL. Combining both checks is useful, but interpretation should be evidence-based and not overblown. Beware of tests marketed without clinical validation. My advice: use established clinical markers (glucose, HbA1c, lipid panel) and treat genetic add-ons as supplementary, not decisive.
