Key result
Heart rate reactivity to laboratory stressors showed the greatest reproducibility (r = 0.555), followed by systolic (r = 0.407) and diastolic blood pressure (r = 0.348).

Moderate reproducibility of BP reactivity limits its utility as a CHD marker; extends evidence on test-retest interval effects.
Meta-Analysis
What is the reproducibility of blood pressure and heart rate reactivity to laboratory stressors?
Effect estimate: r = 0.555 for HR, 0.407 for SBP, 0.348 for DBP
The drop in stress reproducibility as test-retest interval increases places limits on the viability of BP reactivity as a strong marker or risk factor for coronary heart disease.
Swain et al. (1996) conducted a meta-analysis in Blood pressure and heart rate reactivity. Laboratory stressors was evaluated on Reproducibility of heart rate and blood pressure reactivity (r = 0.555 for HR, 0.407 for SBP, 0.348 for DBP). Heart rate reactivity to laboratory stressors showed the greatest reproducibility (r = 0.555), followed by systolic (r = 0.407) and diastolic blood pressure (r = 0.348).
