Cardio Risk Check: can a DNA test help?

The MyBody-X Cardio Risk Check is a blood test measuring traditional risk factors like lipids and hsCRP – it does not analyze DNA. A separate DNA test can examine variants such as APOE (linked to LDL cholesterol) or 9p21 (associated with coronary artery disease). However, the evidence is mixed: individual SNPs have small effect sizes, and polygenic risk scores offer only modest improvement over conventional risk calculators. Most direct-to-consumer DNA tests overstate predictive power. Lifestyle factors (diet, exercise, smoking) and standard clinical markers remain far more important. A DNA test may provide additional context but cannot replace a physician's risk assessment. Be cautious of marketing hype; no single gene determines heart disease risk.
