Question 2

Question 3

slows HR

Question 4

tell me about dilated cardiomyopathy

Answer 4

dilated chambers
most common type
mostly affects middle aged men
systolic dysfunction:
high volumes of blood but low EF (which is percentage of blood being ejected with each contraction)
–low EF means low cardiac output, which leads to left sides HF–> resp complications
eventually–>r sided–> poor prognosis
A fib may develop in addition to embolism
Ventricular dysrythmias

Question 5

treatment for dilated cardiomyopathy?

Answer 5

treatment of HF: Diuretics, ACE inhibitors, ARBs, beta blockers, cardiac glycosides (digoxin positive inotrope)

• Vasodilators
• anti-dysrhythmics
• implantable ICD

Question 6

tell me about hypertrophic cardiomyopathy?

Answer 6

A thickening of the septum and ventricle walls
May be Non-obstructed or Obstructed

-likely cause of death in young athletes (athletes are hyper to win the trophy)

Question 7

Answer 7

do: beta-blockers, anti-dysrythmics, calcium channel blockers

Question 8

what do you avoid with obstructed hypertrophic cardiomyopathy?

Answer 8

vasodilators, cardiac glycosides, diuretics, nitrates, and positive inotropes (dig)

Question 9

normal BNP level?

Answer 9

<100
