|---|---|---|---|---|---|---|---|---|
| Controls (n=79) | Non-penetrants (n=24) | Penetrants (n=35) | p Value* | Controls (n=33) | Non-penetrants (n=12) | Penetrants (n=23) | p Value* | |
| Values are n or mean (SD). | ||||||||
| *p Values for global variance analysis. | ||||||||
| β-MHC, β-myosin heavy chain gene; BMI, body mass index; BP, blood pressure; LA, left atrial; LVMI, left ventricular mass index; MyBPC, cardiac myosin binding protein C gene; non-penetrant, genetically affected but no left ventricular hypertrophy; penetrant, genetically affected with left ventricular hypertrophy. | ||||||||
