PRIMARY HYPERTENSION

1. 95% of all HTN is primary (i.e., essential, idiopathic).

2. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) define the stages of HTN (the average of >2 readings taken from each of >2 visits after the initial screening).

3. Threshold for pharmacologic treatment are defined in JNC 8 based on age, diabetes, and CKD:
• General population < 60 years: < 140/90
• General population > 60 years: < 150/90
• All ages, if CKD or diabetes: < 140/90

4. Goal: SBP < 150 mmHg and DBP < 90 mmHg, which reduces stroke, heart failure, and CHD. Strong Recommendation­ Grade A.
