Circulating levels of total (CD31(+)/CD42a(-)) and activated (CD62E(+)) microparticles released by endothelial cells were significantly decreased (∼40% for both) after a 6-mo supervised aerobic exercise training program in individuals with prehypertension.
The highest odds ratios for prehypertension were those associated with the cutoff points for IOAFi and LAP (e.g., OR = 2.8 for women with WC > 83.5 cm and OR = 2.6 for men with WC > 87.5 cm).
In the case of pHTN, increased adiposity causes dysregulation of the renin-angiotensin-aldosterone-system (RAAS) as well as adipokine- and leptin-associated increases in adrenergic tone.
472 healthy, normotensive subjects [normotension (NT) group], 454 prehypertensive subjects [prehypertension (PH) group] and 978 hypertensive patients [essential hypertension (EH) group] were screened for an association study between 5'-UCR -1248 A>G of Mfn2/HSG and hypertension by polymerase chain reaction and DNA sequencing after venous blood was drawn and DNA was extracted.
We determined whether nod-like receptor with pyrin domain containing 3 (NLRP3) involved in the process of prehypertension, central blockade of NLRP3 decreased inflammation reaction, regulated neurohormonal excitation, and delayed the progression of prehypertension.
These findings indicate that at the stage of pre-hypertension a disturbance in the ANF-c-GMP regulatory pathway may occur, which is expressed primarily at the circulatory rather than the renal excretory level.
Circulating levels of total (CD31(+)/CD42a(-)) and activated (CD62E(+)) microparticles released by endothelial cells were significantly decreased (∼40% for both) after a 6-mo supervised aerobic exercise training program in individuals with prehypertension.
In the present review, we critically analyse the current means used to diagnose PA along with the role that ACTH, aberrant receptor expression and genetic alterations may exert, and provide evidence for an increased prevalence of aldosterone dysregulation in patients with essential hypertension and pre-hypertension.
Although a familial occurrence of subtle disturbances in AngII-dependent control of aldosterone and renal hemodynamics appears possible, BP regulation by the renin-angiotensin system is probably often intact at the stage of prehypertension.
Losartan administered at the onset of prehypertension is more effective than amlodipine in ameliorating hypertension and improving vascular remodeling and function, which is likely mediated by the renin-angiotensin-aldosterone system.

In the Dallas Heart Study, 2001 untreated participants 18 to 64 years of age (mean age: 42.3 years; 44% black race) were divided into the following groups based on office blood pressure (BP) measurements: (1) optimal BP (systolic BP [SBP] <120 mm Hg and diastolic BP [DBP] <80 mm Hg; n=837); (2) prehypertension (SBP 120-139 mm Hg and DBP 80-89 mm Hg; n=821); (3) ISH (SBP ≥140 mm Hg and DBP <90 mm Hg; n=121); (4) isolated diastolic hypertension (SBP <140 mm Hg and DBP ≥90 mm Hg; n=44); and (5) systolic-diastolic hypertension (SBP ≥140 mm Hg and DBP ≥90 mm Hg; n=178).
Risk of total CVDs, MI, and stroke was increased with low-range prehypertension (low-range: SBP 120-129 mmHg and/or DBP 80-84 mmHg) versus normal BP - RR 1.42 (95% CI 1.29-1.55), 1.43 (1.10-1.86), and 1.52 (1.27-1.81), respectively - and risk of total CVDs, CHD, MI, and stroke was increased with high-range prehypertension (high-range: SBP 130-139 mmHg and/or DBP 85-89 mmHg) - RR 1.81 (95% CI 1.56-2.10), 1.65 (1.13-2.39), 1.99 (1.59-2.50), and 1.99 (1.68-2.36), respectively.
Those who converted to normotension were younger, less obese, and had significantly lower baseline SBP, fasting glucose, cholesterol levels, and homeostasis model assessment insulin resistance compared with study participants who continued to have prehypertension or progressed to hypertension.
