Cardio 4 geriatrics Flashcards
Blood pressure stages
normal BP < 120 and < 80
elevated BP 120-129 and < 80
stage 1 130-139 or 80-89
stage 2 >/= 140 or >/= 90
MCC secondary HTN
renovascular
blood pressure goals
< 140/90
<150/90 for 60 and older
HTN emergency/urgency
SBP > 180 or DBP > 120
tx HTN emergency
IV BP agents - MAP reduced by 10-20% in the first hour and an additional 5-15% over the next 23 hours
tx HTN urgency
gradual reduction of MAP by 25% over 24-48 hours with clonidine or captopril
what is restrictive cardiomyopathy
diastolic dysfunction in a non-dilated, rigid ventricle –> impedes ventricular filling
causes of restrictive cardiomyopathy
amyloidosis (MC)
sarcoidosis
hemochromatosis
what heart sound is MC in restrictive cardiomyopathy
S4
dx restrictive cardiomyopathy
echo
endomyocardial biopsy - criterion standard
echo for restrictive cardiomyopathy
non-dilated ventricles
diastolic dysfunction
biatrial enlargement
if amyloidosis - bilateral ventricular wall and inter ventricular septal thickness
endomyocardial biopsy for amyloidosis/restrictive cardiomyopathy
apple-green birefringence with Congo red stain
what is HCM
autosomal dominant genetic disorder of inappropriate LV and/or RV hypertrophy –> LV outflow obstruction, diastolic dysfunction, and ischemia
PE for HCM
S4
pulsus bisferiens - double pulse
EKG for HCM
LVH
prominent Q waves
