heart failure pathophys and Myocarditis

Question 1

clinical symptoms of HF

Answer 1

increased JVD, pulm edema/isp cracked, cool extreme, slow organ perfusion, lateral LV impulse, cres/decrease, chest pain/stemi

Question 2

shock def

Answer 2

low tissue perfusion» ischemia/infarct. leads to necrosis/organ disfunction

Question 3

types of shock

Answer 3

hypovolemic, cariogenic, septic, obstructive

Question 4

hypovolemic shock

Answer 4

low preload (bleeding)

Question 5

cariogenic shock

Answer 5

loss of contractility (MI

Question 6

septic

Answer 6

vasodilation/dehydration, decrease afterload

Question 7

obstructive shock

Answer 7

blocked flow

Question 8

types of HD

Answer 8

HFrEF, HFpEF, restrictive

Question 9

HFrEF

Answer 9

systolic, lost myocardium leads to lost contractility

Question 10

HFrEF

Answer 10

increased stiffness, increased filling p (hypertrophic cardio or HTN/DM

Question 11

restrictive HF

Answer 11

infiltration witth foreign… R sided HF ( increased compliant)

Question 12

neurohumoral activation

Answer 12

adrenogenic/renin lead to vasoconstriction, sodium retention, and fibrosis

Question 13

good neurohumoral activation (just not enough)

Answer 13

natruetic peptide > vasodilation and sodium excretion
