Does salt-sensitivity predict systolic blood pressure reactions to mental stress in healthy young males?
Salt-sensitivity, along with BMI and anxiety, is a significant predictor of systolic blood pressure reactivity to mental stress in healthy young men, potentially contributing to essential hypertension risk.
Individuals whose mean arterial blood pressure is depending on oral salt intake are considered salt-sensitive and are at risk of developing essential hypertension. This study investigates the role of salt-sensitivity with respect to systolic blood pressure reactions under standardized mental stress. Forty-three healthy young males, previously characterized as salt-sensitive (n=16) or salt-resistant (n=27) by a dietary regimen, were subjected to multimodal physiological measurement during a computerized stress test and underwent comprehensive psychometrical testing. The most important predictors for systolic blood pressure reactions to stress were the degree of salt-sensitivity, body mass index and psychological characteristics like anxiety. The highest correlations with the degree of salt-sensitivity were found for the parameters age, systolic blood pressure reaction under stress, high frequency band of heart rate variability and two psychological variables. The concept of salt-sensitivity is a novel biological component that might contribute to reactivity research in subjects at high risk for essential hypertension.
Deter et al. (Mon,) conducted a observational in Healthy (n=43). Salt-sensitivity vs. Salt-resistance was evaluated on Systolic blood pressure reactions to standardized mental stress. Salt-sensitivity, body mass index, and anxiety were the most important predictors for systolic blood pressure reactions to standardized mental stress in healthy young males.
