Evidence check: Cardio Risk Check | Herz-Kreislauf Risiko-Test in the context of sleep

The requested 'Cardio Risk Check' (Herz-Kreislauf Risiko-Test) is not directly mentioned in the provided context. The available information covers short-chain fatty acids (SCFAs), vitamin D, hormone and nutrient tests, and bifidobacteria – but no specific cardiovascular risk test. Therefore, I cannot provide an evidence-based assessment of this test from the context alone. In general, classic cardiovascular risk markers such as LDL cholesterol, HDL, triglycerides, blood pressure, and hsCRP are well-supported by evidence (grade: human-moderate to strong). The link between sleep and cardiovascular risk is also established: insufficient sleep, sleep apnea, and circadian disruption increase the risk of hypertension, inflammation, and metabolic dysfunction. However, it is unclear whether a single DTC test combining these markers offers clinical added value. Many such tests lack standardization and do not provide personalized actionable recommendations. I recommend discussing any results with a physician and not using them as the sole basis for treatment decisions. Evidence grade: mixed (established markers, but the test as a whole is not sufficiently validated).
