JNC 7 Staging of Hypertension in Cardiovascular Pathology

Hypertension is discussed as a component of metabolic syndrome, alongside obesity, hyperglycemia, and hyperlipidemia, with staging defined by blood pressure cutoffs (140/90 mmHg marking the boundary of stage one hypertension) that determine escalation toward hypertensive urgency and emergency. Management principles connect pharmacologic mechanism to physiology, exemplified by thiazide diuretics acting on the sodium-chloride channel in the distal convoluted tubule, a site also relevant to parathyroid hormone signaling.
