Heritability estimates for baseline blood pressure and blood pressure response to the Cold Pressor Test

Trait* Heritability Estimate (Standard Error) P value % of variance explained by
Measured Covariates* Additive Genetic Effects
Systolic blood pressure
 Baseline 0.27 (0.08) < 0.0001 26 20
 Response (iAUC):
  Reactivity (0 – 2 min.) 0.15 (0.07) 0.005 14 13
  Recovery (2 – 5 min.) 0.14 (0.06) 0.006 15 12
Diastolic blood pressure
 Baseline 0.21 (0.08) 0.0008 23 17
 Response (iAUC):
  Reactivity (0 – 2 min.) 0.27 (0.08) < 0.0001 5 25
  Recovery (2 – 5 min.) 0.20 (0.07) 0.0003 10 18

iAUC = incremental Area Under the Curve

Adjusted for age, age2, sex, age- and age2-by-sex interactions, body mass index, resting heart rate, and for response phenotypes only the baseline blood pressure.
