Quantitative Genetic Analysis of Blood Pressure Response During the Cold Pressor Test

Measures of BP at rest and during cold immersion are significantly influenced by additive genetic effects. These genetic influences are only partially shared between SBP at rest and SBP during cold immersion, suggesting that a somewhat different set of genes may influence SBP during cold immersion. Unique sets of genes also appear to influence ΔSBP independent of those influencing resting SBP.
