Q

Systolic anterior motion of mitral valve in ___ CM

Increases w/ (increased/decreased) contractility and (increased/decreased) LV volume

A

Hypertrophic

Increases w/ INCREASED contractility (exertion) and DECREASED LV volume (dehydration)

Q

Tx of hypertrophic CM

Caution w/ what medications?

A
  1. BB*, verapamil, disopyramide
    Sx: myomectomy, ETOH ablation

CAUTION w/ digoxin (increases contractility), nitrates, diuretics (decreases volume)

17
Q

What medication should be avoided in Hypertrophic Obstructive Cardiomyopathy?

A

Nifedipine

d/t peripheral vasodilator properties –> increase left ventricular outflow obstruction
