Association of blood pressure components with mortality and cardiovascular events in prehypertensive individuals: a nationwide population-based cohort study.

Background: The effects of each blood pressure index [systolic and diastolic blood pressure (SBP, DBP), pulse pressure (PP), mean arterial pressure (MAP)] on the occurrence of mortality and cardiovascular (CV) events have not yet been investigated in prehypertensive populations.

Methods: A total of 30,258 prehypertensive Korean participants underwent periodic health examination between 2003 and 2004 were enrolled, and the associations of BP components with mortality and CV events were investigated. Moreover, based on the DBP [80 ≤ DBP <90 mmHg (N = 21,323) and DBP <80 mmHg (N = 8,935)], the effects of BP components were also evaluated.

Blood Pressure Control During Chronic Kidney Disease Progression.

Background: Hypertension is a major cause of end-stage renal disease, and blood pressure (BP) control is crucial in patients with chronic kidney disease (CKD). However, it is generally inadequately controlled in CKD patients. We investigated the prevalence of CKD patients with inadequate BP control and its related factors, based on the CKD stage.
