PC HTN
causes
HIGH circulating catecholamines, arteriolar stretch SNS activity,
-
High renin activity only 10% of patients. 60% have normal levels, and 30% have low levels.
Intracellular Na+ is elevated in primary (essential) hypertension. An increase in intracellular Na+ may lead to increased intracellular Ca2+

-
genetic
-
Liddle syndrome
autosomal dominant condition characterized by early-onset hypertension, hypokalemic alkalosis, low renin, and low aldosterone levels.
-
-
LOW renal perfusion pressure, low intravascular volume, & hypokalemia. #
-
Diagnosis
multiple BP reading
-
-
sphygmometer best, computer does pulse wave
-
-
secondary HTN
-
-
caused by these
Kidney disease
Pheochromocytoma-benign adrneal tumor
Coarctation of aorta
Thyroid/parathyroid disease
Primary aldosteronism (often in patients with DMT2)
Obstructive sleep apnea
Rx related (e.g., NSAIDs, cold remedies, some antidepressants)
steroid therapy
cushing's
-
hirsutism in women, ED in men
-
-
Population Specific
-
more HTN, less repsonse to ACE inhibitors
Aging
-
Black persons with hypertension and older patients tend to have lower plasma renin activity, which may be associated with expanded intravascular volume.
-
if dystolic and systolic are different classes, choose higher class
Tests
Creatinine, BUN, serum Na+ K+
-
-
-
Fasting serum TC, triglycerides, HDl, LDL
-

Tx
Rx
-
3 medications or more, consider divided dosing (AM/PM). Increasing evidence links sleep-time blood pressure and incidence of CV disease.

Excercise
-
Don't increase f, intensity & duration all on same day

JNC 8
age 60, non-diabetic, no chronic kidney disease goal= <150/90
< age 60, all diabetics, all with chronic kidney disease goal= <140/90
if goal not reached in 1 mo, add Rx or up dose

risk of CVD doubles for every 20/10 mmhg over 115/75. That means that at 135/85 we are presumably already at risk
