Heart failure Flashcards
mean arterial pressure formula
DBP- 1/3(PP)
what causes heart failure
arrhythmias (tachy/brady/LBBB/afib) MI/infarction infection PE iatrogenic
high output heart failure
normal heart cant meet abnormal demand
systolic heart failure
heart failure with a reduced ejection fraction
diastolic heart failure
preserved EF, very common esp elderly women
what do the clinical manifestations of heart failure depend on
rate at which it develops and whether enough time as elapsed for compensatory mechanisms to become operative
typical cause of acute failure
ischemia or mechanical
treatment of acute failure
diuretics, nitrates, O2, NO BB
treatment for chronic heart failure
BB can be used carefully and a million other drugs
effect of BB in chronic heart failure
reduces effects of catecholamine stimulation d/t SNS trying to make the heart work right
what is a poor marker for survival in patients with systolic heart failure
elevated norepi levels
mechanical treatment of systolic heart failure
pacemaker- biventricul, IACD, pump
treatment of chronic diastolic heart failure
treat co morbidities and prevent
cause of valvular heart disease
reduces CO by interfering with chamber empting/filling/diversion
