HTN — Hypertension

What HTN means

HTN denotes persistently elevated arterial blood pressure — conventionally readings at or above 130/80 mmHg by current cardiology-guideline definitions. It is the single most common modifiable cardiovascular risk factor and is classified as primary (essential) in roughly nine of ten affected patients.

HTN in clinical practice

Question banks emphasize threshold values, out-of-office confirmation with ambulatory monitoring, and first-line drug classes including thiazide diuretics, ACE inhibitors, ARBs, and calcium channel blockers. The ClinIQ cardiology hypertension article consolidates these decision points with guideline citations.
