High Home Blood Pressure Variability Associates With Exaggerated Blood Pressure Response to Cold Stress

BACKGROUND Exaggerated sympathetic cardiovascular (CV) reactivity to stress associates with elevated risk for clinical and preclinical end points of CV disease. It would be useful to identify these individuals, preferably from feasible measurements commonly used in health care. Our study examined the association between home blood pressure (BP) variability and cardiac workload response to whole-body cold exposure. METHODS Seventy-five men (55–65...
