Association of Systolic Blood Pressure Variability With Mortality, Coronary  Heart Disease, Stroke, and Renal Disease

This study investigated the association of increased visit-to-visit variability and all-cause mortality, cardiovascular events, and end-stage renal disease (ESRD) in a large cohort of U.S. veterans.MethodsFrom among 3,285,684 U.S. veterans with and without hypertension and normal estimated glomerular filtration rates (eGFR) during 2005 and 2006, we identified 2,865,157 patients who had 8 or more outpatient BP measurements. Systolic blood pressure variability (SBPV) was measured using the SD of all SBP  values (normally distributed) in 1 individual. Associations of SD quartiles (
