- heart disease
- DM
- dyslipidemia

- sleep apnea
- sedentary LS
What is the patho of HTN in the gero population?
-accumulation of atheroslerotic plaques —> loss of elasticity of arteries from atherosclerosis —> impaired baroreceptor function (greater r/o ortho hypo) —> increased vascular resistance —> decreased renal function

Prolonged hypertension target organs
- Heart: MI, HF, CAD

- Peripheral vascular disorders
HTN Clinical manifestations
- mainly asymptomatic
- retinal damage (late sign)
- CAD, angina, MI, LVH (left ventricular hypertrophy), HF (all late signs)
- increased BUN, creatinine, nocturnal (CKI) (late sign)
- TIA (transient ischemic attack), stroke, cerebral infarction (late sign)
Assessment and diagnostic studies for HTN (BP, lab levels, kidney, heart, what else)
- patients history
- BP measurement: Both arms and pulses
- cholesterol levels, serum Na and K
- kidney: Creatinine, GFR
- heart: Cardiac markers, ECG, echocardiogram
- retinal exam, brain MRI
Non-pharmacological management for all patients (5)
- heart healthy diet (DASH): culturally appropriate
- reducing sodium intake—- <2g/day
- increasing physical activity
- limiting alcohol
- losing weight for those who are overweight
