Hypertension can cause
CVA, vision loss, vessel damage, kidney failure, bone loss, MI
Normal BP
<120 / <80
Prehypertension

Stage 1 hypertesion
140--99
Stage 2 hypertension
>160 / >100
Hypertensive emergency
>180 />120
Hypertension medications include
ACE inhibitors, beta blockers, calcium channel blockers and angiotensin 2 blockers
,ACE inhibitors work by
Help relax the veins and arteries to lower blood pressure. They block an enzyme in the
body that converts a chemical called angiotensin I into angiotensin II. Angiotensin II is a
strong blood vessel constrictor.

Calcium channel blocker side effects
decreased BP, bradycardia, prolong AV block headache, unusual discomfort,
peripheral edema
First line hypertension treatment for African Americans and Hispanics
Calcium channel blockers
, Angiotensin 2 receptor blocker examples
losartan, valsartan

-pine

-lol
ACE inhibitor medications end in
- pril
What is heart failure?
Poor contractility of the heart, blood is not being pumped efficiently
Lab indicator of heart failure
high BNP
Why does BNP elevate in heart failure
ventricular myocardium is stretched which leaks BNP into circulation
Normal BNP level
<100
What diagnostics are performed for heart failure
Echocardiogram, chest x-ray, cardiac catheterization
Echocardiograms do what?
show the heart structure, blood being pumped through, and ejection fraction
Chest x-rays do what?
Show cardiomegaly
Cardiac catheterization does what?
