Flashcards in Renal hypertension II Deck (14):
what is seen on CXR in coarctation of the aorta?
what are the signs and symptoms of coarctation of the aorta?
- history of HTN
- SOB on exertion
- arm / leg BP greater than 20 systolic difference
- delayed pulses
how does a low sodium diet affect ACE / ARB therapy? why?
low sodium diet may make HTN more sensitive to treatment with ACE / ARB (increaes renin release and makes BP more angiotensin II dependent)
what tests are used to diagnose pheochromocytoma (low and high suspicion)?
- low index: 24 hour urine metanephrines and catecholamines
- high index: plasma for fractionated metanephrines
why do you not use a beta blocker first prior to pheo surgery?
unopposed alpha receptor stimulation
how does hypothyroidism cause HTN?
- decrease CO
- increase PVR
- increases DIASTOLIC BP
how does hyperthyroidism cause HTN?
- increase CO
- decreased vascular tone
- increased SYSTOLIC BP
steps to diagnosis of HTN
- step 1: accuracy (must have elevated BP on at least an initial screen and then 2 or more repeat visits)
- step 2: classification
- step 3: CVD risk factors
- step 4: target organ damage
- step 5: identifiable causes
how are steps 1, 2, and 3 done to assess for HTN?
- ancillary studies
BP goals are set based on what criteria?
- kidney disease status
goal BP for patients over 60 without DM / CKD
goal BP for patient under 60 without DM / CKD
goal BP for all ages WITH DM or CKD
