define heart faluire |
inadequate ability of the heart to to pump enough blood to meet the blood flow and metabolic needs of the body |
|
|
what causes low output HF? |
result of low CO caused by impaired cardiac function |
|
|
What is the problem in systolic heart failure? What usually causes this type of HF? |
contraction phase, reduced ejection fraction less than 40%, circular ventricle CAD/MI |
|
|
What is the problem in diastolic HF? what usually causes this type of HF? |
problem with relaxation and filling, preserved ejection fraction, thick ventrcle HTN |
|
|
what causes the effects of systemic congestion? what is the typical side effect? |
failiing right ventricle edema |
|
|
what causes the effects of pulmonary congestion? what is the typical side effect? |
failing left ventricle SOB |
|
|
what can left or right HF lead to eventually? |
both ventricles eventually fail |
|
|
define stroke volume |
amount of blood pumped out by the left ventricle |
|
|
define preload define afterload |
venous return total peripheral resistance |
|
|
what happens to franksterling in the heart? |
a failing heart does not increase strength of contraction with greater stretch |
|
|
common causes of HF? |
CAD, HTN, dilated cardiomyopathy |
|
|
what is the difference between concentric and eccentric hypertrophy?? what causes these changes? |
concentric is response to pressure overload and heart gets thick eccentric is respoonse to MI and heart gets thinner angiotensin 2 and aldosterone |
|
|
what is BNP and how does it relate to HF? |
substance from the ventricles that increases in response to HF |
|
|
what maybe the causes of of exacertbation in heart failure? what meds can cause it |
uncontrolled HTN, acute ischemia, nonadherence, meds non dhp, bb, rosiglitazone, nsaid, cox2, doxorubicin |
|
|
what are the symptoms of HF? what are the signs? |
dyspnea, sob, exercise intolerance, bloating peripheral edema, s3, juglar venous distension, pulmonary rales |
|
|
describe the levels of heart failure from ACC/ACH |
a- high risk w/o structural heart disease or symptoms of HF b-structural heart disease w/o symptoms of HF c-structural heart disease with symptoms of HF d- structureal heart disease and refractory HF symptoms at rest |
