Heart failure Flashcards
(45 cards)
another name for heart failure
congestive heart failure
what is heart failure
complex clinical syndrome resulting from structural or functional cardiac disorders
pumping difficulties
systolic heart failure
-depressed EF
difficulty filling
diastolic heart failure
-preserved EF
normal venrticular pumping
SVC/IVC->RA-RV-Pulmonary artery-> lungs-> pulmonary veins-> LA-> LV-> systemic circulation
symptoms of heart failure
- fatigue
- poor stamina
- dyspnea: on exertion
- paroxysmal nocturnal dyspnea: in bed at night
- nocturnal cough (orthopnea)
- abdominal fullness, bloating, nausea
- edema
signs of heart failure
- resting tachycardia
- low systolic BP and narrow pulse pressure
- volume overload
- elevated BP
- hepatojugular reflex: press on abdomen
- pulmonary rales
- S3, S4 or summation gallop
- displaced PMI
- murmurs: mitral or tricuspid regurgitation
- hepatomegaly
why have shortness of breath: left side
difficulty of pumping/filling-> back pressure goes into pulmonary circulation-> liquid seeps into alveoli-> alveolar edema (pulmonary edema)
- high pulmonary venous pressure
- see narrow pulse pressure
why have shortness of breath: what happens on right side
back pressure goes-> pulmonary artery
- high pulmonary artery pressure
- get jugular-venous distention
- can go to liver-> ascites
- edema
what is seen on X-ray
pulmonary infiltrates
-enlarged heart (maybe)
what is heard on auscultation of lungs?
crackles or rales on lung bases
symptoms of right CHF
ankles swelling
weight gain
fatigue
muscle atrophy
heart failure pathophysiology
- decreased CO
- poor circulation to organs
- low circulation to musculoskeletal system
- low circulation to kidneys
low circulation to kidneys results in
increase RAA-> salt and water retention, plasma volume expansion, and increased preload
what happens to heart in CHF: systolic heart failure
in systolic heart failure: heart muscle walls thin, cavity sites get bigger
Etiology of heart falire
coronary artery disease=atherosclerosis hypertension diabetes alcohol valvular heart disease viral familial
what happens to heart in CHF: diastolic heart failure
in diastolic heart failure: heart muscle thickens, and cavity site gets smaller
how to we stage heart failure
- Stage A: at risk of CHF (have diabetes, alcoholics)
- Stage B: asymptomatic structural disease (thinning wall or thickening wall)
- StageC: previous/current symptoms
- Stage D: refractory symptoms
class I classifications
no symptoms and no limitations to ordinary physical activity
class II
mild symptoms to ordinary physical activities
class III
marked symptoms with less than usual activity, comfortable at rest
class IV
severe limitations and symptoms at rest. Bed bound patient
steps in diagnosis of CHF
- clinical exam
- ECG
- chest film
- BNP
- echocardiography
what to look for on CXR
- enlargement of heart base
- congested lungs
