Hypertension is a multisystem disease whose hallmark is the elevation of blood pressure.
Classification
| Blood pressure classification | Initial blood pressure mm Hg | Followup recommended | ||
|---|---|---|---|---|
| SBP | DBP | |||
| Normal | <120 | and | <80 | Recheck in 2 years |
| Prehypertension | 120-139 | or | 80-99 | Recheck in 1 year |
| Stage 1 Hypertension | 140-159 | or | 90-99 | Confirm within 2 months |
| Stage 2 Hypertension | >160 | or | >100 | "Evaluate or refer to source of care within 1 month. For those with higher pressures (e.g., >180/110 mmHg), evaluate and treat immediately or within 1 week depending on clinical situation and complications." |
Diagnosis
Treatment
Current clinical practice guidelines are based on The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7).[1]
Treatment goals
Per the JNC7 Guidelines:[1]
- "Treating "most patients" SBP and DBP to targets that are <140/90 mmHg is associated with a decrease in cardiovascular complications.
- In patients with hypertension and diabetes or renal disease, the BP goal is <130/80 mmHg.
Initial medication
Several randomized controlled trials have compared initial medications for hypertension.[2][3][4][5] For patients with Stage 2 Hypertension (SBP >160 or DBP>100 mmHg), start with two drugs.[1]
Systolic hypertension
