The appropriate and timely evaluation and treatment of patients with severely elevated blood pressure is essential to avoid serious adverse outcomes. Most importantly, the distinction between a hypertensive emergency (crisis) and urgency needs to be made. A sudden elevation in systolic (SBP) and/or diastolic blood pressure (DBP) that is associated ...

The beta2-adrenergic receptors (beta2ARs) play a role in renal Na+ regulation. Subjects homozygous for glycine at amino acid 16 (Gly16) of the beta2AR have been shown to have enhanced beta2-mediated vascular relaxation when compared to subjects homozygous for arginine (Arg16). However, Gly16 subjects have been shown to have higher blood ...

BACKGROUND: Most healthy people exhibit a decrease in systolic blood pressure (SBP) at night. A drop of less than 10% from mean daytime values (nondipping) is associated with chronic kidney disease, insulin resistance, and cardiovascular events. Whether nondipping precedes a decline in renal function remains unclear. We hypothesized that nondipping ...

Experimental evidence and several small studies in humans suggest that HMG-CoA (3-hydroxy 3-methylglutaryl coenzyme A) reductase inhibitors (statins) reduce blood pressure, perhaps through effects on endothelial function or by reducing inflammation. We tested the hypothesis that pravastatin would reduce blood pressure at 3 months and the risk of developing new ...
